Scope: Assessment of close-range kinetic counter-FPV systems, automated gun solutions and layered counter-UAS development in France, Italy, Germany, the United Kingdom, the EU and NATO, with a 2026–2031 outlook.

Executive Summary / BLUF

• The premise is only partly correct: companies are already developing automated kinetic counter-drone weapons, including an Italian remote turret integrating eight Benelli Drone Guardian shotguns.
• France has officially documented 12-gauge counter-drone experimentation, but the claimed delivery of 400 Benelli M4 A.I. Drone Guardians is not yet confirmed by an admissible procurement, acceptance or ministry record retrieved for this assessment.
• The Benelli M4 A.I. is semiautomatic, not fully automatic; its manufacturer defines 0–50 metres as optimal and 100 metres as a borderline envelope.
• A shotgun is inexpensive because the soldier supplies detection, identification, tracking and fire control. Automating those functions converts a cheap firearm into a sensor–software–turret–power–command system.
• Full automatic fire does not solve the decisive problems: early detection, target discrimination, engagement authority, ammunition depth, pellet dispersion, collateral risk and residual warhead danger.
• Medium-calibre automatic guns, proximity/airburst ammunition, interceptor drones and directed-energy systems offer greater defended volume, but at materially higher acquisition and integration cost.
• The dominant 2026–2031 direction will be a high-low, layered architecture: passive protection and electronic warfare; interceptor drones and automatic guns; then shotguns or smart small arms as the terminal emergency layer.
• The procurement priority should therefore be affordable cost per defended attack, not the lowest price per weapon or per round.

FPV Drone Defence: Europe Has Cheap Weapons but an Expensive Kill Chain

France’s adoption of a purpose-designed 12-gauge counter-drone weapon captures both the urgency and the danger of Europe’s response to FPV warfare. The Benelli M4 A.I. Drone Guardian is optimized for engagements inside 50 metres and uses dedicated tungsten ammunition, yet that economy exists only at the end of a far more expensive process. A drone must first be detected, classified, tracked and assigned to an effector before a soldier or automated mount can fire. Germany is buying Skyranger 30 vehicles, France is developing PARADE and RAPIDFire, Britain is funding sensors and directed energy, while Italy operates ACUS and portable jammers. Europe does not lack weapons. It lacks a sufficiently distributed and interoperable architecture capable of turning an affordable shot into a reliable defeat before the warhead reaches its target.

France has institutionalized the final 50 metres, not solved them

The Benelli M4 A.I. Drone Guardian is a semiautomatic 12-gauge weapon with a manufacturer-declared optimal envelope of 0–50 metres. Its seven-round standard capacity—or six Magnum cartridges plus one chambered round—gives an infantryman a credible final defensive action, while the AD-LER cartridge uses tungsten shot for a declared envelope extending to 100 metres. No public military record in the dossier supplies probabilities of detection or kill at 25, 50 or 100 metres.

That evidentiary gap defines the weapon’s role. At 50 metres, an illustrative FPV travelling at 20 metres per second covers the remaining distance in 2.5 seconds. Detection, identification, authorization, aiming and any second engagement must occur inside that interval. Even a successful hit does not cancel the momentum of the airframe, battery or warhead. The shotgun therefore improves the infantryman’s survival prospects after the preceding defensive layers have failed; it does not replace them.

The reported delivery of 400 Drone Guardian weapons to the French Army is not confirmed in the dossier by a French procurement notice, budget document or acceptance record. What is documented is the weapon’s purpose-built configuration and France’s wider movement toward layered defence. The distinction matters because a manufacturer’s declared range, a delivery claim and a field-validated military capability are three different evidentiary categories.

The automatic shotgun exists, but automation imports the expensive functions

DUALEE has demonstrated the LIVET remote-controlled weapon station with eight Benelli M4 Drone Guardian shotguns, automatic target tracking and remote engagement. Its configuration shows that industry can generate a dense terminal pattern without resorting to a missile or medium-calibre cannon. It also shows why “build an automatic shotgun” is not the industrial answer it appears to be.

The LIVET installation requires a sensor to acquire the target, software to maintain the track, mechanical equipment to orient the weapons and an operator or control architecture to authorize engagement. Its disclosed live tests at Rio Salso do not establish military qualification, procurement, combat performance or autonomous lethal-release authority. The eight shotguns are the visible component; target-quality surveillance, fire control and safe employment constitute the system.

A soldier supplies many of those functions without a separate procurement line: eyes, contextual identification, aim correction and awareness of friendly forces. Automating the weapon transfers each function into radar, electro-optical equipment, computing, communications and mechanical stabilization. The cartridge can remain inexpensive while the installed capability becomes a capital asset.

Europe already buys automatic counter-drone cannon at system prices

Germany’s February 2024 Skyranger 30 order demonstrates the full cost of moving the engagement beyond shotgun range. The €595 million contract, including value-added tax, covers one prototype and 18 production vehicles, with an option for 30 additional systems. It combines a Boxer platform, sensors, missiles, a 30×173 mm KCE revolver cannon and programmable airburst ammunition.

The €595 million cannot be divided by 19 and presented as the price of a cannon. It finances a prototype, vehicle integration, production systems and associated support whose individual values are not disclosed. The programme instead reveals what governments purchase when they demand mobility, surveillance, protected crews, target-quality tracking and repeated engagement rather than a stand-alone automatic weapon.

France is pursuing a heavier route through RAPIDFire. By June 2025, the disclosed production contract covered 48 systems, including 14 naval installations; the companies reported the first systems operational aboard French replenishment ships. RAPIDFire carries as many as 140 ready 40 mm rounds and recalculates target speed and direction after each shot, but its land variant remained under development.

The dedicated RAPIDFire A3B anti-air ammunition was at technology-readiness level 5 in June 2025, with full anti-air capability expected in 2027. An initial 500-round batch had been contracted in late 2024. France therefore had a fielded naval mounting, qualified existing ammunition and a developmental dedicated counter-air projectile—not one uniformly mature capability.

The United States Army’s XM1228 BADGER follows a more economical model by adapting the M242 25 mm cannon already installed on Bradley vehicles. In January 2026, the Army said the proximity-fuzed round would require no weapon modification, with safety testing planned during 2026 and formation delivery expected in 2027. The programme reduces the need for a direct hit, but it still depends on the vehicle receiving an accurate track and placing the projectile within the fuze’s effective geometry.

Four European states are assembling different layers of the same defence

France has the broadest visible vertical structure. The PARADE programme combines detection, classification, decision support and neutralization of micro- and mini-drones. Its first order covered six systems, with €33 million in firm commitments inside a €350 million programme budget over 11 years. PARADE addresses fixed sites and deployable protection; RAPIDFire supplies a cannon layer; the M4 A.I. Drone Guardian addresses terminal survival.

Germany is concentrating on mobile protection for mechanized forces. Its Skyranger 30 fleet is intended for short- and very-short-range defence, while the Bundeswehr’s May 2026 future-battlefield demonstration connected IRIS-T SLM, Skyranger, unmanned reconnaissance and artificial-intelligence-assisted processing into a protective screen. Nineteen initial Skyranger vehicles cannot cover the entire force, making networked cueing and subordinate self-protection indispensable.

Britain is directing money toward the enabling architecture. The July 2026 Defence Investment Plan allocated £400 million to integrated air-and-missile-defence tactical command-and-control and sensing, more than £750 million to counter-drone capabilities including low-cost ground effectors, and £490 million to directed-energy weapons. Those allocations recognize that the sensor and decision network is not ancillary expenditure: it determines whether the effector can act.

Italy has demonstrated ACUS and portable jammer deployment, including the Italian Air Force contribution to security for the 2022 FIFA World Cup in Qatar. Leonardo markets Falcon Shield as a modular system combining detection, tracking, prioritization and mitigation. The dossier does not establish an Italian force-wide roadmap linking those capabilities to mobile kinetic effectors for manoeuvre formations. Italy’s industrial strength in radar, electro-optics, electronic warfare and integration therefore exceeds its publicly documented operational architecture.

Common interfaces matter more than a common European gun

NATO’s 2026 Layered Counter-UAS Initiative brought together approximately 500 personnel, 215 technical systems and 21 Allied nations. A 2024 NATO counter-drone exercise had already assembled more than 450 participants and over 60 technologies, including sensors, jammers, cyber interceptors and drone-on-drone systems. These numbers describe industrial abundance but also integration debt.

Europe does not need France, Germany, Italy and Britain to buy the same weapon. It needs one national sensor to transmit a usable track to another supplier’s interceptor or cannon. That exchange must include time-stamped position, velocity, uncertainty, classification confidence, friendly-aircraft information, weapon availability and engagement status. A warning that a drone exists in a sector is not automatically accurate enough to programme an airburst round.

The European Defence Industrial Strategy of March 2024 invites member states to procure at least 40% of defence equipment collaboratively by 2030, source at least 50% of procurement value from the European defence industrial base by 2030 and raise intra-EU defence trade to 35% of the EU market. These are policy targets, not achieved outcomes. Their counter-drone value will depend on whether collaborative procurement produces open interfaces or merely finances multinational purchases of closed systems.

The European Commission’s February 2026 Action Plan on Drone and Counter-Drone Security connects detection, response, readiness and mass production with Horizon Europe, the European Defence Fund, the European Defence Industry Programme and SAFE. The EU can aggregate demand and condition financing; it cannot determine tactical engagement authority. NATO and national forces must convert industrial interoperability into military procedures.

Ammunition policy must count pellets, fuzes, interceptors and electricity

The Act in Support of Ammunition Production allocated more than €500 million across European supply chains: approximately €248 million for powder, €124 million for explosives, €90 million for shells, €50 million for missiles and €2 million for testing and reconditioning. The Commission expected the supported investments to contribute to an annual shell-production capacity of two million by the end of 2025.

That objective concerned industrial capacity, not verified output or counter-drone magazine depth. A 155 mm production line does not automatically supply 12-gauge tungsten cartridges, 30×173 mm programmable rounds, 40CT ammunition or miniature proximity fuzes. Counter-drone munitions add dependence on processors, batteries, seekers, motors and electronic fuze components—precisely the inputs that headline shell figures do not measure.

Interceptor drones must also be treated as consumable ammunition when each engagement destroys the interceptor. NATO’s November 2025 demonstration of Merops in Poland used cues from several radars, including an Italian-produced RPS-42. US representatives placed the interceptor’s approximate price at $14,500; the dossier does not contain an independently published NATO audit of the reported Ukrainian combat results.

Directed energy reverses but does not eliminate the ammunition burden. Britain estimated approximately £0.10 per engagement for its Radio Frequency Directed Energy Weapon after more than £40 million in research and development. DragonFire carried an estimated £10 firing cost alongside a £316 million delivery contract announced in November 2025. Cheap electrical discharge follows expensive acquisition, power, cooling, sensing and integration.

The next 24 months will price Europe’s fragmentation

Between September 2026 and September 2028, the decisive outputs will be physical rather than rhetorical: Germany’s initial Skyranger deliveries, France’s progress on A3B ammunition and RAPIDFire Land, Britain’s conversion of £1.64 billion across sensing, counter-drone capabilities and directed energy into deployable equipment, and Italy’s decision on whether ACUS-era site protection becomes mobile formation defence.

If those programmes retain incompatible command systems, Europe will pay repeatedly for radar coverage, software integration, testing and national ammunition variants. Infantry units will pay operationally through shorter warning times; vehicle crews and artillery positions will pay through exposure to drones that cannot be assigned quickly enough to an available effector; finance ministries will pay through duplicated development and small production runs; industry will pay through uncertain demand that does not justify surge capacity.

The alternative already exists inside the disclosed programmes: soldier-level terminal weapons, battalion sensors, mobile cannon, electronic attack, interceptors and directed energy connected through common interfaces and supported by multi-year ammunition orders. The next 12–24 months will determine whether Europe turns those elements into a force or preserves them as a catalogue.

Master Abstract

The last 50 metres is becoming an infantry responsibility

France’s significant doctrinal step is not the invention of an anti-drone shotgun. It is the recognition that very-short-range air defence can no longer remain solely the responsibility of specialist air-defence units. The French Ministry of the Armed Forces documented training by the 2e Régiment d’infanterie de marine in which soldiers used 12-gauge weapons to neutralise drones at distances up to 50 metres. The same activity combined drone reconnaissance, local adaptation and repair, and the construction of attack drones close to the manoeuvre unit. This places drone employment and terminal drone defence inside the ordinary infantry battle rather than in a separate technical function. Quand les marsouins s’adaptent à la guerre des drones — Ministère des Armées — Mar 2026

The subsequent claim that the French Army has received 400 Benelli M4 A.I. Drone Guardian shotguns is plausible and reportedly derives from an Army announcement. It cannot, however, be elevated to established procurement fact under the present evidence protocol. No accessible French procurement notice, contract award, delivery-acceptance document or Ministry web publication retrieved in this session establishes the quantity, delivery date, receiving formations or assertion that the weapon is replacing a standard French 12-gauge model. The defensible baseline is therefore: French experimentation is officially confirmed; the 400-unit delivery remains an attributed but insufficiently documented assertion.

Benelli describes the M4 A.I. Drone Guardian as a 12-gauge, gas-operated semiautomatic weapon, holding seven standard or six Magnum cartridges plus one chambered round. The 18.5-inch version weighs 3.9 kilograms unloaded. Benelli describes 0–50 metres as the optimal engagement range and 100 metres or more as a “borderline” shot. These are manufacturer-declared specifications, not published military probability-of-kill results. M4 A.I. Drone Guardian 18,5″ — Benelli Defense — accessed Sep 2026

The associated AD-LER ammunition is a 12/70 cartridge with a tungsten load and declared muzzle velocity of 405 metres per second. Benelli states a 0–100 metre range but also limits compatibility to shotguns proofed to 1,320 bar and recommends restricted choke configurations. No public test record retrieved provides shot-pattern density, target aspect, drone speed, number of rounds per defeat, environmental conditions or residual-warhead outcomes across that full envelope. Ammunitions — Benelli Defense — accessed Sep 2026

The operational distinction is fundamental. A successful pellet strike can disrupt propellers, motors, batteries or control electronics, but it does not necessarily render the payload safe. At 50 metres, a fast FPV retains momentum and may still cross much of the remaining distance after losing controlled flight. Its fuze or explosive charge may remain functional. The shotgun therefore reduces the probability of an accurate strike; it does not create a guaranteed safe stand-off distance.

Companies are automating kinetic interception—but not at firearm economics

The proposition that industry is not developing automatic weapons in this direction is contradicted by the public record.

Italy’s DUALEE has disclosed live testing of the LIVET Remote Controlled Weapon Station, integrating eight Benelli M4 Drone Guardian shotguns, target auto-tracking and remote engagement. The company presents it as a system for critical infrastructure, strategic assets and high-intensity counter-UAS missions. This is precisely an industrial attempt to automate the shotgun concept. The disclosed evidence establishes a company-tested demonstrator; it does not establish military qualification, procurement, autonomous firing authority or combat performance.

Russia’s Two-Stage Drone Strike System: The Geran-2 as FPV Carrier Platform

The LIVET architecture also exposes the underlying economics. The barrels and cartridges are the inexpensive components. An operational automated system additionally requires:

• persistent cueing or an external warning network;
• electro-optical, infrared, acoustic, radar or radio-frequency detection;
• target classification and friend–foe discrimination;
• high-acceleration tracking drives and stabilisation;
• ballistic prediction for a three-dimensional manoeuvring target;
• secure command links and human engagement controls;
• power supply, environmental protection and vehicle or fixed-site integration;
• safety certification, ammunition storage and rapid reloading;
• testing against clutter, weather, multiple axes and simultaneous targets.

Once these functions are included, the relevant comparator is no longer “shotgun versus missile”. It is complete defended sector versus complete defended sector.

Germany has selected a heavier version of the same logic. Its Skyranger 30 combines a 30×173 mm automatic revolver cannon, programmable airburst ammunition, missiles and an integrated sensor suite on a Boxer vehicle. The February 2024 contract was worth €595 million including VAT for one prototype and 18 production vehicles, with an option for 30 more. The contract value cannot be divided into a defensible unit price because it incorporates a development and delivery package whose public breakdown is not provided.

France is pursuing the 40 mm RAPIDFire family. The naval version is remotely operated; its fire-control system recalculates aim after each shot using the target’s motion. Thales and KNDS declare an engagement range of up to four kilometres and a ready rack of up to 140 rounds. Fourteen naval systems had been ordered by the DGA by June 2025, while a broader production contract covered 48 systems. The dedicated A3B anti-air airburst round was still at Technology Readiness Level 5 in June 2025, with full anti-air operational capability forecast for 2027. RAPIDFire Land was then a planned development, not a fielded land capability.

The United States is similarly modifying existing automatic weapons rather than designing only new launchers. The US Army’s XM1228 BADGER programme applies a miniature proximity sensor to 25 mm ammunition for the Bradley’s M242 chain gun. According to the Army, the round is intended to detonate when sufficiently close to a drone, reducing dependence on a direct hit or a manually programmed burst point. Safety testing was planned for 2026 and entry into formations was expected in 2027; those statements describe a development schedule, not present fielded availability.

These examples show why a fully automatic shotgun is not automatically the preferred design. Increasing cyclic rate consumes a small magazine almost immediately, increases recoil and dispersion, complicates remote mounting and does not expand the weapon’s engagement envelope. Against several independently manoeuvring FPVs, detection and fire-control latency generally matter more than the difference between semiautomatic and fully automatic cycling. A multibarrel installation such as LIVET increases ready ammunition and sector response, but also increases mechanical complexity, reload burden and the danger area created by multiple clouds of high-density projectiles.

FPV Drone Production: How U.S.-Ukraine JVs Are Reshaping Defense

The emerging solution is layered, distributed and selectively automated

Electronic warfare remains valuable but is no longer a sufficient organising principle. Radio-silent autonomous drones, frequency-agile links and fibre-optic FPVs reduce the effectiveness of conventional jamming. NATO’s 2025 Innovation Challenge explicitly identified fibre-optic drones as a problem because many standard counter-UAS systems depend on jamming or spoofing; their low signature, direct control and manoeuvrability increase the need for physical interception. NATO’s 16th Innovation Challenge Counters Fibre-Optic Controlled FPV Drones — NATO Allied Command Transformation — Jun 2025

Nevertheless, replacing electronic warfare with guns would reproduce the same single-layer vulnerability. NATO’s Layered Counter-UAS Initiative defines the requirement as connecting sensors, command-and-control systems and different effectors. Its first 2026 Crucible event brought together approximately 500 personnel, 215 technical systems and 21 Allied nations, illustrating that interoperability—not merely effector lethality—is now the principal institutional problem. Layered Counter-UAS Initiative (LCI-X) is Building NATO’s Approach to a Fast-Moving Threat — NATO Allied Command Transformation — May 2026

NATO had already tested more than 60 counter-drone technologies involving sensors, jammers, cyber interceptors and drone-on-drone systems during its September 2024 interoperability exercise, attended by over 450 participants from 19 Allies and three partner countries. This breadth confirms that no single effector covers the complete problem. Ukraine joins NATO counter-drone exercise for first time — NATO — Sep 2024

Interceptor drones are developing into the intermediate layer between electronic warfare and guns or missiles. NATO reported in December 2025 that the Merops interceptor demonstrated in Poland cost approximately US$14,500 per vehicle, according to US officials, and could accept cues from different radars. NATO also relayed US claims of more than 1,000 successful interceptions in Ukraine; those operational totals remain attributed rather than independently audited. NATO and the US Army demonstrate low-cost counter-UAS system to protect NATO airspace — NATO — Dec 2025

Directed-energy systems offer another low marginal-cost layer, but marginal shot cost must not be confused with total cost per operational defeat. The UK Ministry of Defence estimates approximately £0.10 per RF-directed-energy firing, a range up to one kilometre and more than 100 drones defeated across trials. It also states that more than £40 million had already been invested in research and development. The weapon remained a demonstrator whose operational deployment depended on further development. British soldiers take down drone swarm in groundbreaking use of radio wave weapon — UK Ministry of Defence — Apr 2025

The British DragonFire laser illustrates the same distinction: the MOD declared a marginal firing cost of about £10, but the November 2025 delivery contract was worth £316 million, with initial Royal Navy installation planned from 2027. Energy weapons require generation, storage, cooling, beam control, tracking and maintenance; their economic advantage emerges principally during repeated engagements after the system has been deployed.

United Kingdom	RF-directed energy, lasers, low-cost interceptors and funded short-range counter-drone acquisition	Several capabilities remain demonstrators or early deployments; power and integration costs are substantial	Build a high-low mix rather than select between guns and directed energy
EU/NATO	Common experimentation, interoperability work, European industrial funding and Ukrainian operational feedback	Fragmented requirements, national engagement rules and incompatible interfaces slow scale	Prioritise common track formats, test standards, modular effectors and pooled production

Italy’s Ministry of Defence has publicly documented deployment of portable jammers and the fixed ACUS—AMI Counter UAS system for airspace protection during its Qatar mission. This confirms an operational Italian emphasis on detection and electronic effects, but it does not establish a comparable infantry shotgun programme. Contributo Nazionale — Ministero della Difesa — accessed Sep 2026

The United Kingdom’s July 2026 Defence Investment Plan assigns more than £750 million to short-range counter-drone protection, including Project PRESAGIUM and low-cost ground effectors, within a broader £790 million integrated-air-and-missile-defence package. It also assigns £490 million to directed-energy development. These are portfolio allocations, not unit or engagement costs. The Defence Investment Plan — UK Ministry of Defence — Jul 2026

At EU level, the February 2026 Action Plan calls for improved detection, coordinated responses, industrial cooperation, affordable technologies and accelerated mass production. The mechanism remains predominantly supportive: implementation and engagement authority continue to reside substantially with Member States.

Principal Gaps and Watch Indicators

Records capable of changing the assessment

• French contract award, purchase order or acceptance record confirming the reported 400 M4 A.I. deliveries.
• French Army table of organisation showing whether the intended scale is one weapon per combat group, per platoon or another distribution model.
• Government-controlled trials reporting probability of defeat by range, target speed, approach angle and rounds expended.
• Evidence on whether intercepted FPV warheads detonated, remained armed or continued into the defended area.
• LIVET military qualification, customer order, sensor configuration, ready-ammunition doctrine and human-authorisation architecture.
• Comparable lifecycle costs covering sensors, operators, power, ammunition, maintenance and reload—not merely weapon or firing cost.

Watch indicators for 2026–2031

• Shotgun or smart-fire-control weapons appearing in formal infantry equipment scales rather than isolated trials.
• NATO adoption of common target-track and effector interfaces under LCI-X.
• Qualification and volume production of 25–40 mm proximity or directional-airburst ammunition.
• Vehicle remote weapon stations receiving counter-UAS software and high-elevation modifications without complete turret replacement.
• Operational deployment of RFDEW beyond demonstrations and evidence of effectiveness against shielded or autonomous drones.
• Procurement language shifting from “cost per shot” to cost per raid defeated, defended area, magazine depth and reload time.
• Mandatory terminal protection packages combining warning sensors, overhead protection and a close-range kinetic effector.

The Last 50 Metres: Why the Shotgun Is Valuable but Insufficient

Principal judgment

The shotgun is becoming a legitimate component of infantry counter-FPV defence because it creates a dense projectile pattern using a mechanically simple, portable and comparatively inexpensive weapon. Its value, however, begins precisely where the wider defensive system has nearly failed. At an optimal declared range of 0–50 metres, it offers only seconds to detect, classify, track and engage an incoming drone. It can improve a soldier’s probability of striking a small manoeuvring target, but it cannot provide persistent surveillance, defend a formation against sustained multi-axis attacks or guarantee that an armed drone neutralised at close range will no longer reach the protected position.

The correct institutional response is therefore not to choose between shotguns, electronic warfare and high-technology systems. It is to make terminal kinetic defence available at infantry level while ensuring that earlier layers—passive protection, detection, warning, electronic attack, interceptor drones and automatic guns—reduce the number of threats that enter the final engagement zone.

France has moved the problem into the combat group

The French development is doctrinally important because it treats very-short-range drone defence as an ordinary infantry problem rather than an exclusive responsibility of specialist air-defence formations.

On 11 March 2026, the French Ministry of the Armed Forces documented counter-drone experimentation by the 2e Régiment d’infanterie de marine. The activity combined reconnaissance drones, locally adapted attack drones and 12-gauge weapons used by infantry personnel to neutralise aerial targets at distances up to 50 metres. The official record establishes experimentation and training; it does not establish a universal French Army fielding scale or a formal requirement for one shotgun in every combat group. Quand les marsouins s’adaptent à la guerre des drones — Ministère des Armées — Mar 2026

The subsequently reported delivery of 400 Benelli M4 A.I. Drone Guardian shotguns would, if confirmed through a procurement or acceptance record, represent a transition from experimentation to initial institutional distribution. The retrieved official record does not yet establish the contract, delivery schedule, receiving formations or reported replacement of an existing French 12-gauge weapon. The quantity should therefore remain an attributed claim rather than be treated as independently verified inventory.

France is not alone in moving counter-drone shooting into small-arms training. The US Marine Corps included a drone simulation match using the M1014 12-gauge platform in its April 2026 Marksmanship Championship at Quantico. The official video record confirms training activity but publishes no controlled probability-of-hit or ammunition-effectiveness results. Marines participate in Drone Simulation Match (B-Roll) — U.S. Marine Corps Training and Education Command — May 2026

These developments indicate a broader institutional change: the soldier is no longer merely expected to report a drone and await specialist intervention. Infantry formations are beginning to acquire a final, organic opportunity to defeat the threat themselves.

The Benelli is semiautomatic, not an automatic air-defence system

Terminology is important. The Benelli M4 A.I. Drone Guardian is a semiautomatic shotgun: one cartridge is fired for each trigger action, with the gas system cycling the next round. It is not a fully automatic weapon, and it does not independently detect, track or engage a drone.

For the 18.5-inch version, Benelli declares:

Characteristic	Manufacturer specification	Evidentiary qualification
Operating action	Semiautomatic ARGO gas system	Declared configuration
Calibre	12 gauge	Established
Chamber	3-inch Magnum	Established
Standard capacity	7 cartridges plus 1 chambered	Configuration-dependent
Magnum capacity	6 cartridges plus 1 chambered	Configuration-dependent
Unloaded weight	3.9 kg	18.5-inch version
Optimal engagement range	0–50 m	Manufacturer claim; no military Pₖ curve published
Borderline engagement range	100 m or more	Manufacturer’s own qualification
Barrel length	470 mm	18.5-inch version

M4 A.I. Drone Guardian 18,5″ — Benelli Defense — accessed Sep 2026

The distinction between semiautomatic operation and automated engagement explains much of the apparent cost advantage. In the handheld configuration, the soldier supplies most of the expensive functions:

• visual or acoustic detection;
• classification of the object as friendly, hostile or unidentified;
• estimation of range, speed and direction;
• prediction of the interception point;
• weapon alignment and lead;
• decision to fire;
• assessment of whether the drone has been defeated;
• continued observation of the falling aircraft and payload.

The firearm is inexpensive partly because these functions are not incorporated into it. Once cameras, thermal sensors, radar cueing, tracking software, stabilisation, powered traverse, secure communications and engagement controls are added, the result is no longer simply a shotgun. It becomes a counter-UAS weapon system.

Fifty metres represents seconds, not tactical depth

The decisive limitation is time.

The US Army conducted counter-drone ammunition tests in May 2026 against FPV targets travelling at speeds exceeding 40 miles per hour, equivalent to approximately 17.9 metres per second. The exercise evaluated different ammunition types and existing weapons rather than publishing a final system-selection result. Learning Lessons from Ukraine: Cost-Effective Solutions to Counter Drone Operations — United States Army — May 2026

Using that documented threshold solely as an illustrative lower-bound speed:

Distance remaining	Transit time at 40 mph	Operational meaning
100 m	5.6 seconds	Manufacturer-described borderline shotgun envelope
50 m	2.8 seconds	Manufacturer-described optimal-envelope boundary
25 m	1.4 seconds	Extremely compressed recovery or re-engagement interval

Calculated from 40 mph = 17.88 m/s. Actual transit time decreases as drone speed increases and varies with flight path.

These figures are not a probability-of-kill model. They demonstrate the geometry of the problem. If the first warning occurs only as the drone enters the optimal 50-metre envelope, the soldier must orient, identify, shoulder the weapon, acquire lead and fire within a period comparable to a few seconds. A missed first shot leaves little time for correction, even though the weapon cycles semiautomatically.

This makes early warning more important than cyclic rate. A soldier cued ten seconds earlier by another observer, a passive acoustic sensor, an optical detector or a shared tactical network is in a materially better position than a soldier holding a fully automatic weapon but detecting the drone only at close range.

The shotgun improves hit opportunity but does not abolish the aiming problem

The principal ballistic advantage of a shotgun is that each discharge projects multiple sub-projectiles rather than one bullet. The resulting pattern gives the shooter a larger effective interception area and reduces—but does not eliminate—the requirement for an exact point intersection between projectile and drone.

Benelli’s AD-LER ammunition uses a tungsten load in a 12/70 cartridge with a declared muzzle velocity of 405 metres per second. The company declares a range of 0–100 metres and specifies compatibility and proof-pressure conditions. No retrieved official or manufacturer record publishes the pellet count, pattern diameter, pattern density, retained energy, probability of component damage or number of rounds required against defined FPV target sets. Ammunitions — Benelli Defense — accessed Sep 2026

Three different outcomes must consequently remain separate:

1. Projectile contact: one or more pellets strike the drone.
2. Flight defeat: the drone can no longer sustain controlled flight.
3. Threat neutralisation: the drone and its payload can no longer injure personnel or damage the protected asset.

Published marketing language generally addresses the first two without supplying sufficient evidence on the third. A pellet strike on a rotor, motor or control component can produce an immediate loss of flight. A strike that perforates a non-critical structural element may not. Even a drone that is no longer controllable can continue along its existing vector, fall into the defended position or detonate after impact.

The relevant test standard is therefore not simply whether the drone falls. It is whether the complete threat—air vehicle, munition, fuze and residual trajectory—is prevented from producing its intended effect.

The residual warhead remains inside the defended perimeter

At close range, the drone’s explosive payload creates a second problem. Defeating the airframe does not necessarily defeat the munition.

The public record retrieved does not provide a controlled dataset measuring the post-interception behaviour of armed FPVs struck by shotgun pellets at different distances. Several risk mechanisms nonetheless follow directly from the engagement geometry:

• the airframe can retain forward momentum after losing propulsion;
• the operator may already have placed the drone on a terminal trajectory;
• an impact fuze may function when the disabled drone reaches the ground or protective structure;
• fragmentation can remain dangerous even when detonation occurs short of the intended aim point;
• an unexploded payload can create a subsequent explosive-ordnance hazard.

US Army counter-UAS training instructs personnel to treat a defeated drone cautiously: confirm it from a safe distance, clear personnel, cordon the area, communicate with higher command and control the site. This official recovery procedure supports the conclusion that “downed” and “safe” are not synonymous. Enhancing C-sUAS Capabilities: A Comprehensive Training Program — United States Army Air Defense Artillery Journal — Feb 2025

Terminal shotgun defence is therefore more effective when combined with physical measures that manage the residual trajectory: overhead nets, stand-off screens, protected firing positions, compartmentalisation, dispersion and barriers separating personnel from likely impact points. The active and passive layers perform different functions and should not be evaluated as substitutes.

Magazine capacity imposes a hard saturation limit

The M4 A.I. 18.5-inch configuration holds seven standard or six Magnum cartridges plus one in the chamber. This is adequate for a small number of controlled engagements but cannot provide sustained fire against a prolonged or multi-axis raid.

The number of drones that can be engaged before reloading depends on variables that are not publicly established:

• rounds required per target;
• warning time and target spacing;
• whether more than one drone attacks simultaneously;
• approach direction and angular separation;
• shooter competence and fatigue;
• weapon stoppages or ammunition damage;
• visibility, background clutter and weather;
• the need to retain ammunition for ground combat.

Even assuming one round per successful interception would be unjustified without test evidence. A single shotgun must therefore be treated as a limited-capacity emergency effector, not as a miniature anti-aircraft battery.

Issuing several shotguns across a squad increases the number of available engagements and provides coverage across different sectors, but it also imposes burdens. Ammunition and the additional weapon must be carried; responsibility for air watch must be assigned; engagement sectors must be deconflicted; and personnel concentrating overhead become less able to observe and engage ground threats.

The organisational question is not simply “how many shotguns?” It is how to distribute observation, cueing, engagement and reloading responsibilities without degrading the infantry unit’s primary mission.

Why fully automatic fire is not the obvious solution

A fully automatic shotgun appears attractive because it would place more pellets into the engagement volume in less time. That advantage is real but narrow. It does not resolve the principal limitations and introduces new ones.

Ammunition is exhausted faster

A high cyclic rate rapidly consumes a small ready magazine. Unless the weapon uses a large box, drum, belt or multibarrel arrangement, automatic operation can shorten rather than extend the number of engagement opportunities before reloading.

Recoil and dispersion reduce controllability

The weapon must remain aligned with a small target moving in three dimensions. Recoil during automatic fire can widen dispersion beyond the intended intercept volume. A remote mount can absorb and correct movement more consistently than a person, but that requires stabilisation, powered drives and fire-control integration.

A higher firing rate does not improve detection

If the drone is discovered at 20 metres, the governing problem is warning time. Faster cycling cannot recover the seconds already lost through inadequate surveillance.

More projectiles enlarge the danger zone

Every missed projectile continues beyond the target. Automatic fire increases the number of pellets entering the surrounding airspace and terrain, which complicates employment near friendly troops, civilian infrastructure, vehicles, fuel and ammunition stores.

The shooter still needs an engagement solution

A dense projectile cloud placed behind or below the target remains a miss. The system still requires target tracking, lead calculation and correct timing.

The most promising automatic-shotgun approach is consequently not an infantry weapon fired continuously from the shoulder. It is a remotely operated, sensor-cued installation such as LIVET, in which DUALEE has integrated eight Benelli M4 Drone Guardian shotguns with auto-tracking and remote engagement. The company reports live testing at the Rio Salso range, but it has not published a military qualification record, probability-of-kill dataset, engagement doctrine or procurement customer. DUALEE LIVET RCWS – Advanced C-UAS Capability — DUALEE — Jun 2026

LIVET demonstrates that the proposed direction is technically being pursued. It also confirms the central economic point: meaningful automation is achieved by adding sensors, software, mechanical tracking and a controlled firing architecture—not merely by increasing the firing rate of one shotgun.

The correct infantry configuration is a system, not a firearm

A credible soldier-level capability requires at least five connected elements.

Early warning

The engagement team must be alerted before the drone enters the final 50 metres. Warning can originate from observers, passive sensors, vehicle systems or higher-echelon surveillance. The cue does not necessarily need to provide weapon-grade tracking; even a reliable sector and estimated arrival time materially improves readiness.

Identification and authority

The unit requires clear criteria for distinguishing hostile drones from friendly aircraft, reconnaissance systems and other airborne objects. The shorter the engagement range, the less time exists to resolve uncertainty. Identification procedures and rules of engagement must therefore be established before contact.

Suitable weapon and ammunition

The shotgun should be evaluated as a combined weapon–barrel–choke–ammunition configuration. Manufacturer compatibility restrictions show that ammunition cannot be treated as universally interchangeable. Testing must examine reliability, pattern consistency, retained effect and component damage under operational conditions.

Assigned sectors and fire control

Multiple shooters require defined observation and engagement sectors. Without sector discipline, several soldiers can fire at the same target while another approach remains uncovered. A local commander must also decide when the terminal defence role takes precedence over observation or ground engagement.

Post-engagement protection

The unit must anticipate falling drones, functioning payloads and unexploded ordnance. Physical protection and recovery procedures complete the defeat mechanism.

The US Army’s training model reflects this broader structure. It begins with visual, audible and digital detection; proceeds through identification and reporting; distinguishes passive from active defence; and requires safe handling of the defeated aircraft. It does not define kinetic fire as the entire counter-UAS mission. Enhancing C-sUAS Capabilities: A Comprehensive Training Program — United States Army Air Defense Artillery Journal — Feb 2025

The procurement test should measure threat defeat, not target breakage

Before large-scale adoption, governments need a common, auditable test programme. At minimum, the evaluation matrix should include:

Test variable	Required measurement	Decision relevance
Range	10, 25, 50, 75 and 100 m where safe	Identifies the credible—not merely claimed—envelope
Target motion	Closing, crossing, diving and evasive profiles	Prevents results from stationary or predictable targets being generalised
Speed	Defined bands with calibrated measurement	Establishes lead and reaction requirements
Visibility	Day, low light, obscuration and clutter	Measures operational rather than range-only performance
Ammunition	Exact cartridge, load, lot, choke and barrel	Ensures reproducibility
Shooter condition	Trained/untrained; rested/fatigued; cued/uncued	Separates weapon performance from training effects
Outcome	Contact, flight defeat, payload defeat and impact point	Prevents “drone fell” from being treated as complete neutralisation
Expenditure	Rounds per engagement and reload time	Determines magazine depth and logistical burden
Safety	Downrange dispersion and residual hazard	Establishes usable deployment environments
Reliability	Stoppages by ammunition and environmental condition	Determines readiness and sustainment requirements

The decisive output should be a probability-of-threat-defeat curve with confidence intervals for each validated configuration. No such government-controlled public dataset was retrieved for the Benelli M4 A.I. Drone Guardian.

Net assessment

The shotgun deserves institutional adoption as a final defensive layer because it is immediately understandable, portable, comparatively inexpensive and less dependent on the electromagnetic spectrum than a jammer. It is especially relevant against fibre-optic or autonomous FPVs and in dispersed formations that cannot expect a dedicated air-defence system at every position.

Its apparent simplicity must not be converted into false sufficiency. The 50-metre envelope is tactically shallow; ready ammunition is limited; the soldier remains the detector and fire-control system; saturation can exhaust the weapon; missed pellets create their own safety problem; and an intercepted warhead can remain dangerous.

The most defensible force-design principle is therefore:

detect beyond the shotgun envelope, disrupt before physical interception becomes necessary, engage kinetically before the payload reaches the protected position, and preserve the shotgun as the final opportunity when every preceding layer has failed.

Key judgments

• France has officially established the relevance of 12-gauge counter-drone training at infantry level, but the reported 400-weapon delivery remains insufficiently documented in the admissible public record.
• The M4 A.I. Drone Guardian is semiautomatic and manufacturer-rated for an optimal 0–50 metre envelope; the claimed 100-metre reach is expressly described as borderline.
• At a documented test-target speed exceeding 40 mph, the final 50 metres represent less than 2.8 seconds of transit time.
• The shotgun’s principal advantage is a larger projectile-interception pattern, not guaranteed target or warhead neutralisation.
• Fully automatic fire improves projectile volume but worsens ammunition consumption, controllability and danger-area management without solving detection or identification.
• The operationally meaningful capability is a combined warning, identification, weapon, ammunition, sector-control and post-impact-protection system.
• Large-scale procurement should follow controlled tests measuring complete threat defeat rather than airframe damage alone.

What would change the assessment

The shotgun’s assessed role would expand if independent military testing demonstrated repeatable defeat of manoeuvring, armed FPVs beyond 50 metres with low ammunition expenditure and a controlled residual impact area.

Its assessed value would contract if testing showed inconsistent pattern density, excessive rounds per target, unacceptable downrange danger, poor performance under operational visibility or frequent survival of the payload after airframe defeat.

Evidence that automated cueing can be supplied to infantry at low weight, low electromagnetic signature and acceptable unit cost would materially improve the shotgun layer without requiring a fully autonomous firing system.

• Exact French intended distribution by combat group, platoon, company or installation.

Automatic counter-drone weapons already exist: the kill chain is the real cost

Principal judgment

Automatic and automated counter-drone weapons are already moving from demonstration into procurement. They include radar-directed automatic cannon, remotely controlled shotgun arrays, programmable and proximity-fuzed ammunition, interceptor drones and directed-energy weapons. The industrial gap is therefore not primarily the absence of a sufficiently rapid-firing weapon. It is the absence, at infantry scale and acceptable cost, of a complete system capable of detecting, classifying, tracking and safely engaging small drones before they enter their terminal attack.

A barrel and ammunition can be inexpensive. A reliable engagement is not. Once a weapon must operate automatically, it requires sensors, target-quality tracking, fire-control computation, platform stabilization, command-and-control integration, identification safeguards, communications, power, testing and trained operators. These elements frequently cost more than the effector and determine whether it can engage in cluttered terrain without striking friendly aircraft, troops or civilians.

The most promising development path is consequently not a universal autonomous gun. It is a modular architecture in which multiple sensors provide a shared track, a human-supervised system assigns the least expensive suitable effector, and short-range guns or shotguns constitute the terminal layer. The evidence indicates that armed forces are already moving in this direction. What remains immature is the ability to distribute that architecture economically across manoeuvre units rather than concentrating it around vehicles, bases and critical infrastructure.

“Automatic” describes four different capabilities

Discussion of automatic counter-drone weapons often conflates mechanical rate of fire with automation of the engagement. They are separate attributes.

Function	Meaning	Public example	What the public record establishes
Semiautomatic firing	One shot for each trigger action; the weapon cycles and reloads itself	Benelli M4 A.I. Drone Guardian	Purpose-designed semiautomatic 12-gauge weapon with counter-drone ammunition; not an autonomous weapon
Automatic cannon fire	The weapon continues cycling while commanded	Rheinmetall Skyranger 30	Vehicle-mounted 30×173 mm revolver cannon integrated with sensors, missiles and programmable ammunition
Automated tracking and fire control	Sensors and software maintain the target track and calculate the firing solution	RAPIDFire; DUALEE LIVET	Automated tracking or recalculated fire-control solutions are declared; human release authority is not necessarily removed
Autonomous engagement	The system selects and attacks a target without a contemporaneous human firing decision	None of the examples below is publicly established in this category	“Autonomous operation” or “auto-tracking” does not by itself prove autonomous lethal-release authority

The Benelli M4 A.I. Drone Guardian remains semiautomatic: its ARGO gas system cycles the weapon, but a soldier still detects, tracks, aims and fires. Benelli declares an optimal engagement distance of 0–50 metres, with 100 metres or more described as a boundary case; those figures are manufacturer-defined envelopes rather than publicly released military probabilities of kill. M4 A.I. Drone Guardian 18.5″ — Benelli Defense

The distinction matters because converting the same shotgun into an automated counter-drone installation does not merely require a motor to pull the trigger. It transfers functions previously performed by the soldier’s eyes, judgment and movement into an electro-mechanical system. Those substituted functions constitute the expensive part.

The automatic shotgun has already been demonstrated

DUALEE’s LIVET remote-controlled weapon station directly challenges the proposition that industry is not pursuing automated shotgun solutions. The disclosed counter-UAS configuration combines eight Benelli M4 Drone Guardian shotguns with automatic target tracking and remote engagement. The company reports live testing at Rio Salso and presents the system as protection for strategic assets and critical infrastructure. DUALEE LIVET RCWS – Advanced C-UAS Capability — DUALEE

The demonstrator illustrates both the attraction and the limitations of the concept. Eight shotguns can create a high-density terminal shot pattern while retaining comparatively inexpensive ammunition. Mounting the weapons removes some human aiming error and allows several barrels to engage almost simultaneously. A fixed or vehicle-mounted station can also carry more ammunition than an individual soldier.

The disclosed record does not, however, establish military qualification, an operational procurement contract, autonomous firing authority, combat effectiveness or probability of kill against different drone classes. Nor does the weapon station remove the requirement for a target-quality sensor. Automatic tracking begins only after the target has been acquired with sufficient positional and velocity accuracy.

LIVET therefore demonstrates technical feasibility, not yet a mature substitute for layered air defence. It is most credible where the protected area is geographically bounded, approach directions can be surveyed, fields of fire can be controlled and a separate sensor network already exists. These conditions are more readily satisfied at an ammunition depot, command post or power installation than around a dispersed infantry section moving through woodland or urban terrain.

Medium-calibre systems already combine the entire chain

The more mature automated kinetic solutions use cannon rather than shotgun cartridges because cannon provide greater range, larger ammunition capacity and access to programmable or proximity-fuzed projectiles.

Skyranger 30: the weapon is only one component

In February 2024, the Bundeswehr ordered one Skyranger 30 prototype and 18 production vehicles, with an option for 30 more. Rheinmetall reported a contract value of €595 million including value-added tax. The package combines a 30×173 mm KCE revolver cannon, programmable airburst ammunition, missile integration, sensors and Boxer vehicle integration. Mobile air defence: Rheinmetall to supply the Bundeswehr with Skyranger 30 on Boxer platform – order worth almost €600 million — Rheinmetall — Feb 2024

The €595 million ceiling should not be divided by 19 and represented as a cannon unit price. The contract covers a prototype, production vehicles and associated integration and support; the published announcement does not provide a component-level price breakdown. What it demonstrates is that acquiring an operational counter-drone gun capability entails much more than purchasing an automatic weapon.

The engagement economics can nevertheless remain favourable compared with missile-only defence. Programmable ammunition allows a cannon to place a destructive volume near a small target without requiring a direct impact. The trade-off is that the platform must know sufficiently accurately where and when to programme the round to burst. The ammunition therefore depends on precise ranging, track prediction and low-latency fire control.

RAPIDFire: automation is migrating from platforms to fire control

Thales and KNDS describe RAPIDFire as a remotely operated 40 mm system whose fire control recalculates the target’s speed and direction after every round. France had ordered 48 systems by June 2025, including 14 naval installations; the companies reported that the first systems were operational aboard French replenishment ships. The land variant remained under development. Thales and KNDS France unveil RAPIDFire Land, a land-based variant of the 40 mm RAPIDFire Naval defence system — Thales — Jun 2025

The same announcement states that qualification with existing 40CT ammunition occurred in early 2025, while the dedicated A3B anti-air ammunition remained at technology-readiness level 5, with full anti-air capability expected in 2027. A late-2024 contract modification covered an initial 500 A3B rounds. Those categories must remain separate: a fielded naval mounting, qualification with existing ammunition and a developmental dedicated anti-air round are not equivalent states of readiness.

RAPIDFire also shows why industry often favours cannon over multiple automatic shotguns. A stabilised 40 mm turret can serve several roles and engage at declared ranges measured in kilometres rather than dozens of metres. The higher acquisition burden buys a larger decision window, broader target coverage and greater utility against targets other than FPV drones.

BADGER: modify the projectile rather than replace the weapon

The United States Army is taking a different route with the XM1228 BADGER, a 25 mm proximity-fuzed projectile intended for the M242 cannon already installed on Bradley vehicles. The Army states that the ammunition requires no modification to the existing weapon. It planned safety testing during 2026 and expected fielding in 2027; those dates describe the programme schedule, not an already deployed capability. Project Manager Maneuver Ammunition Systems Works To Increase Lethality Of Existing Weapon Systems — United States Army — Jan 2026

This approach attacks two major cost drivers: fleet modification and direct-hit accuracy. A proximity fuze containing a miniature radar initiates the warhead near the target, while the existing vehicle supplies the cannon, power, crew and much of the logistical system. The Army’s declared objective is to increase counter-UAS lethality without developing another bespoke launcher.

It does not eliminate the kill chain. The Bradley must still receive a usable track, direct the cannon and place the round close enough for the fuze and fragmentation pattern to work. Retrofitting the effector is economical partly because earlier investments in the platform and its support structure are already sunk.

The cost sits between first detection and confirmed defeat

The counter-drone kill chain can be represented as six connected functions:

Function	Required output	Principal cost or constraint	Consequence of failure
Detect	Initial indication with location and time	Radar, radio-frequency, electro-optical, infrared or acoustic coverage; power; operators	No opportunity to engage
Classify and identify	Target type and confidence that engagement is permissible	Sensor fusion, libraries, friendly-drone coordination and contextual judgment	False engagement or delayed response
Track	Continuous position, velocity and predicted path	Target-quality radar or optical tracking; clutter rejection; communications latency	Fire-control solution becomes invalid
Decide and authorize	Effector assignment and lawful firing decision	Command system, engagement rules, human supervision and deconfliction	Target passes inside the useful envelope
Engage	Correct weapon orientation, timing and ammunition effect	Turret, stabilization, fuze setting, magazine depth, interceptor or energy delivery	Miss, incomplete damage or expenditure of the wrong effector
Assess and re-engage	Confirmation that the threat and payload no longer endanger the force	Continued observation, residual-object tracking and reserve ammunition	Damaged drone or warhead still reaches the protected area

Detection cannot simply be made universal

A small automatic weapon can be carried or mounted widely. High-quality surveillance is harder to distribute. The United States Army has explicitly stated that it cannot install “exquisite” radar on every platform because of both cost and the risk that radar emissions disclose friendly positions. It also identifies fibre-optic-controlled drones as resistant to conventional jamming because they do not depend on an exposed radio-frequency command link. Project Manager Maneuver Ammunition Systems Works To Increase Lethality Of Existing Weapon Systems — United States Army — Jan 2026

Passive electro-optical sensors avoid radar emissions but can suffer from weather, obscuration, background clutter and restricted fields of view. Radio-frequency sensors can provide early warning against transmitting drones but will not detect every autonomous, pre-programmed or fibre-optic-controlled threat. Acoustic detection can be inexpensive but is affected by vehicles, artillery, wind and terrain. No single low-cost sensor reproduces the combined performance of a layered surveillance network.

Classification is harder than detection

A detector must distinguish an attacking FPV drone from friendly unmanned aircraft, birds, debris and other moving objects. This becomes increasingly difficult as both sides operate large numbers of small drones over the same tactical area.

An automatic weapon magnifies the consequences of classification error. A soldier firing a shotgun has immediate visual context and a narrow cone of fire. A radar-directed cannon can act faster and at longer range, but that range expands the volume in which friendly aircraft, civilians and infrastructure must be considered. Greater automation therefore increases the requirement for trustworthy identification, airspace coordination and controlled engagement zones.

Tracking, not cyclic rate, determines the firing opportunity

Small drones present rapidly changing angular motion, particularly during a terminal dive or lateral approach. Increasing the weapon’s cyclic rate does not correct an inaccurate track. It can instead expend the magazine more quickly while increasing collateral hazards.

A useful track must provide position, range, velocity and uncertainty with low enough latency for the fire-control computer to predict an intercept. The requirement becomes stricter as projectile flight time increases. Shotguns partially compensate for imperfect aim by distributing pellets, but their short effective envelope leaves little time to acquire the target, authorize fire and recover from a miss.

Engagement assessment remains necessary

A drone ceasing controlled flight is not necessarily a neutralized threat. Its warhead, battery and fragments retain momentum; a damaged FPV can fall into the defended position or detonate nearby. An automated system must therefore either continue observing the wreckage or pass the assessment to another sensor. This requirement is especially important for terminal weapons, where intercept distance is insufficient to ensure that falling debris lands outside the protected area.

Why “cost per shot” is an incomplete metric

Counter-drone economics are often discussed using the price of the ammunition or energy discharged. That figure is operationally useful but represents only one part of the cost.

Metric	What it measures	What it omits
Ammunition or energy cost per firing	Consumable expenditure when the weapon fires	Sensor, platform, crew, integration and unsuccessful engagements
Cost per engagement	Total consumables used against one track	Detection overhead and engagements that were never attempted
Cost per confirmed kill	Engagement cost divided by verified defeats	Damage assessment uncertainty and non-kinetic mission kills
Cost per defended hour or area	System ownership and operation over time	Consequences of leakage and different threat intensities
Lifecycle cost	Acquisition, training, maintenance, personnel, upgrades and consumables	Strategic value of what is protected
Cost-exchange ratio	Defender expenditure relative to attacker expenditure	Damage prevented, magazine depletion and opportunity cost

The United Kingdom’s Radio Frequency Directed Energy Weapon illustrates the distinction. The Ministry of Defence estimated a firing cost of approximately £0.10 per engagement and reported more than 100 drones tracked, engaged and defeated across trials. It also reported more than £40 million invested in the technology’s research and development and described the tested equipment as a demonstrator that would require further development for operational service. British soldiers take down drone swarm in groundbreaking use of radio wave weapon — UK Ministry of Defence — Apr 2025

The ten-pence figure is therefore a marginal discharge estimate, not the price of supplying a regiment with operational systems. Its value lies in repeated engagement after the capital equipment, power source, sensor and personnel are already present.

The DragonFire laser presents the same pattern. In November 2025, the UK Ministry of Defence described an estimated £10 cost per shot while announcing a £316 million contract for systems intended to begin entering Royal Navy service in 2027. Boost for Armed Forces as new laser weapon takes down high-speed drones — UK Ministry of Defence — Nov 2025

The two values are not contradictory. One describes the marginal cost of delivering energy; the other finances development, production, naval integration and delivery of a usable capability. The comparison reinforces the central judgment: cheap shots become militarily valuable only after expensive enabling systems make them possible.

Why companies do not simply manufacture more fully automatic shotguns

Range determines how much time the system can buy

A target detected at 50 metres and travelling at 20 metres per second crosses the distance in 2.5 seconds, calculated from distance divided by speed. That illustrative calculation is not a claim about a particular drone. It demonstrates why a 50-metre weapon leaves almost no allowance for classification, authorization, aiming, an ineffective first burst or engagement from another direction.

Mechanized cannon, interceptor drones and missiles cost more partly because they move the engagement outward. The added range converts distance into time: time to classify, allocate a weapon, fire again and ensure that debris falls away from the defended force. An automatic shotgun preserves ammunition economy by accepting a much smaller decision margin.

Magazine depth and reloads limit sustained defence

A Benelli M4 A.I. Drone Guardian carries seven standard cartridges or six Magnum cartridges plus one chambered round, according to the manufacturer. M4 A.I. Drone Guardian 18.5″ — Benelli Defense

Fully automatic fire would exhaust that capacity in a very short interval unless the weapon were redesigned around a box, drum or belt-fed system. Such a redesign adds weight, feed complexity and testing requirements. Multiple weapons, as used by LIVET, increase the ready-shot count but also multiply barrels, receivers, mounting points and maintenance tasks.

High cyclic rate is consequently less important than controlled burst density, ammunition effectiveness and rapid target transfer. Against small drones, the design objective is not to place the largest possible number of rounds downrange; it is to create a sufficiently dense intercept pattern at the predicted target position while retaining ammunition for subsequent attackers.

Shot fall creates a safety problem

Pellets and cannon projectiles that miss do not disappear. An automated system intended for use above friendly positions, cities or infrastructure requires defined safe sectors, ballistic limits and firing inhibition. Shotgun pellets lose energy more rapidly than many cannon projectiles, which is an advantage, but a dense automatic burst still creates a substantial volume of falling or ricocheting material.

This limits the attractiveness of unattended automatic shotguns outside controlled perimeter defence. A human-carried weapon remains easier to orient toward a visually confirmed target with immediate awareness of troops and structures behind it.

Saturation is a sensor and scheduling problem

Against several simultaneous drones, the system must determine which threat will arrive first, whether two sensors are tracking the same object, how many rounds to allocate and when to transfer to the next target. More barrels solve only the firing-capacity component.

NATO’s Layered Counter-UAS Initiative explicitly treats the challenge as the integration of sensors, command-and-control, effectors and decision tools. Its 2026 Crucible activity involved approximately 500 personnel, 215 technical systems and 21 Allied nations, illustrating the scale of the interoperability problem rather than a shortage of candidate weapons. Layered Counter-UAS Initiative (LCI-X) is Building NATO’s Approach to a Fast-Moving Threat — NATO Allied Command Transformation — May 2026

A previous NATO counter-drone exercise assembled more than 450 participants and over 60 sensor and effector technologies, including jammers, cyber interceptors and drone-on-drone systems. The number and diversity of systems indicate that integration, common tracks and coordinated engagement are now central capability constraints.

The lowest-cost solution changes with the target

No effector is cheapest across every engagement condition.

Threat or condition	Economically attractive response	Controlling limitation
Radio-controlled drone at useful warning range	Electronic attack	Ineffective against some autonomous, hardened or fibre-optic-controlled systems
Small drone with a stable target-quality track	Automatic cannon with programmable or proximity ammunition	Ammunition, radar and fire-control integration
Drone outside gun range but within a defended corridor	Low-cost interceptor drone	Launch time, guidance, inventory and airspace deconfliction
Multiple electronics-dependent drones in a compact sector	Radio-frequency directed energy	Range, power, electromagnetic compatibility and target susceptibility
Drone in the terminal tens of metres	Shotgun or other close-range kinetic weapon	Minimal reaction time, restricted coverage and residual warhead hazard
Larger or higher-performance aerial threat	Missile, cannon or combined system	Higher expenditure and limited magazine depth

The United States and NATO demonstrated the Merops interceptor in Poland in November 2025 using cues from multiple radar types, including an Italian-produced RPS-42 radar. US representatives placed the interceptor’s approximate price at $14,500 and reported extensive Ukrainian combat use; these remain attributed US claims rather than an independently published NATO audit. NATO and the US Army demonstrate low-cost counter-UAS system to protect NATO airspace — NATO — Dec 2025

The significance is not that an interceptor makes guns obsolete. It demonstrates the value of a sensor architecture able to accept different radar inputs and assign an effector suited to the geometry. The same surveillance track could, in principle, cue an interceptor at longer range, a cannon closer in and a shotgun if the preceding layers fail.

Investment patterns confirm that integration is the priority

The United Kingdom’s 2026 Defence Investment Plan allocated £400 million to integrated air-and-missile-defence tactical command-and-control and sensing, more than £750 million to counter-drone capabilities including low-cost ground effectors, and £490 million to directed-energy weapons. The allocations show substantial expenditure on sensing and command infrastructure alongside the weapons themselves. The Defence Investment Plan — UK Ministry of Defence — Jul 2026

At European Union level, the Commission’s February 2026 Action Plan on Drone and Counter-Drone Security similarly treats detection, coordinated response, readiness, accelerated production and financing as connected requirements. It proposes support through Horizon Europe, the European Defence Fund, the European Defence Industry Programme and the SAFE instrument. Commission publishes the Action Plan on Drone and Counter-Drone Security — European Commission — Feb 2026

These programmes indicate where institutional demand is moving. Governments are not choosing between “cheap guns” and “expensive technology.” They are purchasing the technical and organizational infrastructure needed to make cheap effectors usable at scale.

Where industrial value is moving

The counter-drone market is separating into four industrial layers:

1. Shared sensing and command architecture. Radar, electro-optical, radio-frequency and acoustic systems must create a correlated air picture and distribute it with sufficiently low latency.
2. Fire-control and decision software. The system must predict trajectories, rank threats, recommend an effector and apply firing constraints. This layer is increasingly more differentiating than the mechanical weapon.
3. Modular effectors. Guns, interceptor drones, electronic attack, lasers and high-power radio-frequency systems can be attached to the same command architecture if interfaces are sufficiently open.
4. Specialized ammunition. Tungsten shot, programmable airburst rounds, proximity fuzes and controlled-fragmentation projectiles improve effectiveness without necessarily replacing the installed weapon.

This structure favours companies able to integrate multiple suppliers, certify interfaces and demonstrate performance across realistic environments. A manufacturer offering only an automatic firearm faces a difficult commercial position: the customer must still purchase a sensor and integrator, while the firearm’s effective range limits its role to the final defensive layer.

It also explains why upgrading installed weapons is attractive. BADGER leverages the Bradley’s existing 25 mm cannon; Skyranger combines established ammunition technology with a vehicle and sensor suite; RAPIDFire adapts a naval system toward land applications. These approaches distribute development cost across platforms and missions rather than creating a single-purpose automatic shotgun installation.

Five-year outlook: distributed layers, not one universal weapon

Between 2026 and 2031, the balance of evidence supports five developments.

First, automatic cannon will spread downward from specialized air-defence formations into manoeuvre and installation-protection roles, particularly where armies can adapt existing vehicle weapons and use programmable or proximity-fuzed ammunition. Cost and weight will prevent universal issue.

Second, automated tracking and target prioritization will become more common than autonomous lethal-release authority. Human supervision can be retained at the decision point while sensors and software perform the time-critical calculations. This arrangement captures most of automation’s speed benefit without requiring every identification and authorization judgment to be delegated to software.

Third, counter-drone shotguns will become a standardized terminal capability for selected soldiers, vehicles and fixed installations. Automated multi-shotgun stations are technically credible for controlled perimeters, but their range and ammunition capacity will keep them subordinate to longer-range layers.

Fourth, interceptor drones will occupy more of the cost space between jamming and missiles. Their economic advantage will depend on reusable sensors, scalable production and the ability to receive tracks from an open command architecture.

Fifth, procurement competition will move from headline “cost per shot” figures toward audited performance against defined target sets. Decision-grade comparisons will require detection probability, false-alarm rate, time to engage, probability of kill, simultaneous-track capacity, magazine depth, reload time, protected-area coverage and lifecycle cost. Most of these figures remain absent from the accessible public record.

Key judgments

• The absence of automatic counter-drone weapons is a false premise. Automatic cannon are ordered or fielded; automated shotgun arrays have been demonstrated; proximity ammunition, interceptor drones and directed-energy systems are advancing through procurement and trials.
• A cheap firearm does not create cheap air defence. Target-quality sensing, identification, fire control, authorization, integration and assessment dominate the system burden.
• Full automation does not overcome the shotgun’s physical limitations: short range, small ready-ammunition capacity, restricted engagement geometry and residual warhead risk.
• Cannon and interceptor systems cost more because they purchase distance, and distance creates decision time, re-engagement opportunities and safer debris patterns.
• The economically efficient architecture is layered and modular. Shared sensors and command systems should allocate electronic, kinetic or directed-energy effectors according to target type and range.
• Industrial advantage will accrue increasingly to sensor-fusion, fire-control, ammunition and systems-integration providers, not solely to manufacturers of gun mechanisms.

What would change the assessment

The assessment would strengthen if armed forces publish operational orders for automated shotgun stations, standardized infantry-level sensor cueing or verified performance showing high defeat rates against representative FPV attacks.

It would weaken if longer-range low-cost interceptors or directed-energy weapons demonstrate reliable operation under clutter, adverse weather, electronic attack and saturation at a lifecycle cost low enough for distribution below battalion level. Such performance would reduce the operational space in which automatic guns or shotguns are required.

Evidence that compact passive sensors can provide target-quality tracks without conspicuous emissions would be especially consequential. It would remove one of the principal barriers to distributing automated kinetic effectors across manoeuvre units.

Open official record

• France has not publicly released the contract value, complete delivery schedule, recipient-unit allocation or military acceptance results for the reported M4 A.I. Drone Guardian acquisition.
• No accessible official test record provides comparable probabilities of detection and kill for counter-drone shotguns at 25, 50 and 100 metres against representative FPV profiles.
• DUALEE has not publicly disclosed military qualification, procurement status, target-set results, ready-ammunition doctrine or the firing-authorization architecture of LIVET.
• Published Skyranger, RAPIDFire, RFDEW and DragonFire announcements do not provide sufficiently disaggregated acquisition and lifecycle costs for direct cost-per-protected-area comparison.
• Public records do not yet provide a common NATO or EU performance standard covering detection, tracking, identification, engagement and residual-warhead assessment for this weapon class.
• Comparative data on false engagements, collateral footprints, magazine exhaustion and performance under simultaneous multi-axis attack remain unavailable.

European force design to 2031: distributed layers, common interfaces and scalable ammunition

Principal judgment

By 2031, an effective European counter-drone force will not be defined by possession of one superior interceptor. It will depend on whether armed forces can distribute mutually supporting defensive layers from the individual combat group to the brigade and theatre level, connect nationally procured sensors and effectors through common interfaces, and sustain the resulting architecture with inexpensive ammunition manufactured at scale.

Europe possesses most of the necessary components: soldier-carried shotguns, electronic-warfare systems, passive and active sensors, automated turrets, programmable cannon ammunition, interceptor drones, lasers and high-power radio-frequency demonstrators. The structural weakness is fragmentation. These capabilities are being developed through different national programmes, data formats, engagement doctrines and procurement cycles. Unless interoperability becomes a contractual requirement, Europe risks fielding an expensive collection of capable systems that cannot exchange target-quality tracks, allocate weapons across national boundaries or draw on common ammunition reserves.

The required force-design shift is therefore organizational as much as technological. Close defence must become an organic function of manoeuvre units rather than a scarce specialist service. Sensors should be separated logically from effectors so that a track generated by one national system can cue a weapon supplied by another. Ammunition policy should move from small orders for proprietary rounds toward multi-year procurement of interchangeable families: 12-gauge terminal-defence cartridges, programmable 25–40 mm rounds, low-cost interceptor drones and reusable electrically powered effects.

The central risk is that Europe buys platforms faster than it builds this connective and industrial architecture.

A distributed architecture from the soldier to the theatre

The appropriate design is not a continuous shield in which every unit receives every technology. It is a hierarchy of overlapping engagement opportunities.

Force level	Indicative defensive function	Principal sensors	Suitable effectors	Design constraint
Individual and combat group	Survival inside the final 50–100 metres	Human observation, acoustic warning, compact electro-optical or passive detectors	Shotgun, service weapon with suitable ammunition, concealment and physical protection	Weight, reaction time and residual warhead hazard
Platoon and company	Local warning and close protection of movement or temporary positions	Portable passive RF, optical and short-range radar where signature permits	Jammers, remotely operated guns, shotgun stations, interceptor drones	Power, operator burden, fratricide control and ammunition carriage
Battalion	Correlated local air picture and allocation of close-range effectors	Multi-sensor fusion node linked to subordinate observers and vehicles	Automatic cannon, programmable ammunition, reusable EW and interceptors	Communications resilience and target-track quality
Brigade	Mobile short-range air defence and cross-unit prioritization	Networked surveillance radar, passive detection and higher-echelon feeds	Cannon-missile combinations, directed energy where operationally mature	Scarcity, displacement, radar signature and saturation
Division, corps and theatre	Area warning, reinforcement and defence against larger or higher-performance threats	Integrated air-defence surveillance and external intelligence feeds	Longer-range missiles, aircraft and reinforcement of lower layers	Magazine allocation and competition with higher-value threats

This hierarchy should not be interpreted as a rigid allocation of particular weapons. Terrain, threat density, emissions discipline and unit mission will change the mix. Its value lies in assigning responsibilities: the infantry layer protects against leakage; the company and battalion layers create repeated low-cost engagement opportunities; the brigade and theatre layers manage the wider air picture and defeat threats beyond the reach of local systems.

Germany’s stated force-development concept already points toward this model. In a May 2026 Army demonstration, the Bundeswehr described a protective screen built from networked sensors, electronic warfare, air defence, long-range fires and artificial-intelligence-assisted data processing. The disclosed exercise connected IRIS-T SLM, Skyranger 30, unmanned reconnaissance systems and a real-time situational picture. The Bundeswehr also retained a human decision for the final employment of demonstrated loitering munitions. Gefechtsfeld der Zukunft: Wie das Heer kämpfen wird — Bundeswehr — May 2026

That demonstration is evidence of a force-design direction, not proof that the complete architecture is fielded across the German Army. It nevertheless captures the decisive principle: survival increasingly depends on the speed with which a sensor observation becomes an authorized effect.

Distribution must extend beyond specialist air-defence units

Traditional short-range air defence is organized around a limited number of valuable systems. FPV drones create a different problem. They can approach individual vehicles, gun positions, command posts and dismounted troops simultaneously. A small number of centralized systems cannot maintain continuous line-of-sight coverage across dispersed terrain or accompany every local movement.

Europe therefore requires distribution of functions rather than duplication of complete systems.

The lowest levels need passive warning, visual identification, immediate reporting and a terminal defensive weapon. Platoons and companies require access to portable detection and at least one effector able to engage before the final dive. Battalions need the first genuine fusion layer: a node able to correlate local reports, remove duplicate tracks and cue mobile guns, electronic attack or interceptors. Brigade air defence should concentrate on threats that require greater range, fire-control quality or missile performance.

This arrangement preserves scarce high-performance systems while reducing the number of targets that reach them. It also avoids the opposite error of expecting every soldier or vehicle to operate an independent radar-directed weapon.

The Bundeswehr publicly describes counter-drone defence as a mixture of long-, medium-, short- and self-protection capabilities. It identifies Skyranger 30 as one component of a larger defensive mosaic and acknowledges that mass drone employment can exhaust ammunition stocks. Drohnen und Drohnenabwehr in Deutschland und der Ukraine — Bundeswehr — Oct 2025

Distribution also requires redundancy. A radio-frequency detector will not cover every fibre-optic or autonomous drone; an electro-optical system will not provide uninterrupted performance in all visibility conditions; an active radar can be detected and targeted. The design objective should therefore be graceful degradation: loss or suppression of one sensor type should reduce performance, not collapse the entire local defence.

Common interfaces are more important than a common weapon

Europe does not need every state to purchase the same radar, turret or interceptor. It does need systems to exchange information without bespoke integration each time a new effector is introduced.

At minimum, a common counter-UAS interface should transmit:

• time-stamped target position and velocity;
• track uncertainty and sensor provenance;
• classification and identification confidence;
• predicted approach and impact area;
• friendly-aircraft and restricted-fire information;
• effector availability, remaining ammunition and engagement status;
• weapon-assignment and human-authorization state;
• post-engagement assessment.

The difficulty is that not every sensor track is suitable for every weapon. A general warning that a drone exists in a sector can cue human observation but cannot necessarily direct programmable cannon fire. The architecture must therefore label track quality instead of treating every detected object as a fire-control solution.

This is also a procurement issue. If governments acquire complete proprietary chains—one vendor’s radar, command system and effector—the integration problem is initially reduced, but future substitution becomes expensive. If an interceptor becomes unavailable or a new ammunition type performs better, the customer may remain technically or contractually tied to the original supplier.

NATO’s Layered Counter-UAS Initiative is addressing the system-of-systems problem by bringing sensors, effectors and decision tools into a shared experimental environment. Its 2026 activity involved approximately 500 personnel, 215 technical systems and 21 Allied nations. The scale demonstrates the breadth of available technology and the unresolved burden of connecting it. Layered Counter-UAS Initiative (LCI-X) is Building NATO’s Approach to a Fast-Moving Threat — NATO Allied Command Transformation — May 2026

The appropriate 2031 objective is therefore not immediate universal standardization. It is a certified interoperability framework under which national systems can publish and consume agreed track, command and status information. Proprietary internal algorithms can remain protected while the interfaces required for coalition operations become testable.

Ammunition must be designed as a scalable portfolio

Counter-drone ammunition is not one industrial category. It includes pellets, conventional projectiles, programmable rounds, proximity fuzes, interceptor drones, missile components and electrical power. These products have different supply chains and should not be aggregated into a single headline production figure.

Terminal ammunition

Dedicated 12-gauge cartridges offer the fastest route to widespread terminal defence because existing weapons, storage procedures and training structures can be adapted. Benelli’s AD-LER cartridge uses tungsten shot and is declared by the manufacturer for a 0–100 metre envelope. The company does not publish military probability-of-kill data across that range. Ammunitions — Benelli Defense

Scaling this layer requires more than purchasing tungsten cartridges. European users need comparable testing of shot density, effectiveness against representative airframes, behaviour after partial damage, barrel compatibility and danger areas. Without a common test framework, each national customer risks buying small proprietary lots whose performance cannot be compared.

Tungsten also creates a supply-security consideration. High-density material improves retained pellet energy, but increased dependence on specialized inputs can undermine the economic advantage if demand rises sharply. Qualification of alternative loads, multiple European suppliers and recoverable surge contracts would reduce that exposure.

Cannon ammunition

Programmable and proximity-fuzed 25–40 mm rounds provide the central kinetic layer because they extend the engagement envelope and reduce the requirement for a direct hit. Europe already has several relevant gun families, but fragmentation in calibre, fuze programming, fire-control integration and vehicle architecture can divide demand into uneconomic production runs.

France’s RAPIDFire programme uses 40CT ammunition. Thales and KNDS reported qualification with existing rounds in early 2025, while the dedicated A3B anti-air round remained at technology-readiness level 5 and was expected to provide full anti-air capability in 2027. An initial 500-round batch had been contracted. Thales and KNDS France unveil RAPIDFire Land, a land-based variant of the 40 mm RAPIDFire Naval defence system — Thales — Jun 2025

Germany’s Skyranger 30 uses 30×173 mm programmable airburst ammunition, while the United States is adapting 25 mm Bradley ammunition through the XM1228 BADGER proximity fuze. These are parallel industrial pathways, not interchangeable stockpiles. A European policy of “common ammunition” cannot erase installed weapon differences by 2031. It can, however, standardize test targets, fuze-safety requirements, electronic programming interfaces and multi-year demand signals.

Interceptor drones

Low-cost interceptors should be treated as ammunition when they are consumed during each engagement, even if they contain guidance and computing systems normally associated with platforms. Their production model must therefore resemble high-volume munitions manufacturing: simplified variants, rapid acceptance, replaceable software and assured stocks of motors, batteries, processors and seekers.

This category offers greater reach than a shotgun and potentially lower expenditure than a missile, but its economics depend on scale. Small national orders for different designs will prevent suppliers from investing in automated production. Aggregated procurement can create volume, provided that users agree on target categories, command interfaces and minimum performance rather than prescribing identical internal designs.

Reusable electrical effects

Lasers and high-power radio-frequency systems invert the ammunition problem. Their marginal firing costs can be very low, but the system requires power generation, cooling, sensors and maintenance. They reduce dependence on physical magazines but do not provide unlimited capacity: thermal management, weather, range, electrical supply and target susceptibility become the new constraints.

The United Kingdom reported estimated firing costs of approximately £10 for DragonFire and £0.10 for its Radio Frequency Directed Energy Weapon demonstrator. Those figures exclude acquisition and enabling infrastructure. DragonFire was placed under a £316 million delivery contract in November 2025, while more than £40 million had been invested in the radio-frequency programme’s research and development. Boost for Armed Forces as new laser weapon takes down high-speed drones — UK Ministry of Defence — Nov 2025 British soldiers take down drone swarm in groundbreaking use of radio wave weapon — UK Ministry of Defence — Apr 2025

Directed energy should consequently supplement scalable ammunition rather than be used to justify smaller physical inventories before operational performance is established.

National trajectories remain materially different

Italy: strong integration potential, incomplete public force architecture

Italy has an established operational baseline in fixed-site counter-drone protection. The Italian Air Force reported deploying the fixed ACUS counter-UAS system together with portable jammers during its contribution to security for the 2022 FIFA World Cup in Qatar. Primo impiego operativo della capacità Counter-UAS in Qatar — Aeronautica Militare — Dec 2021

That record establishes an integrated detection and electronic-response capability for a defined security mission. It does not establish force-wide distribution, effectiveness against fibre-optic or autonomous FPV drones, or a mobile kinetic component accompanying Italian manoeuvre formations.

Italy’s industrial position is stronger than the limited public procurement record suggests. Leonardo markets Falcon Shield as a modular, scalable system combining sensors, threat prioritization and mitigation. Because this is a company claim, operational performance, national inventory and military availability cannot be inferred from it. Falcon Shield — Leonardo in the UK

Italy’s 2031 opportunity is to become an integration hub rather than pursue an exclusively national effector family. Its radar, electro-optical, electronic-warfare and command-system base can connect Italian and allied weapons. This would also allow the country to protect ports, air bases, naval installations and deployed land forces through related architectures rather than separate procurement silos.

The unresolved requirement is an officially documented path from fixed-site detection and jamming to mobile, layered kinetic defence. Without that transition, Italy will retain useful protection against susceptible drones but remain exposed when electronic attack cannot break the control or navigation link.

France: the most visible vertical layering

France has the clearest public progression across several counter-drone layers. The PARADE programme covers detection, classification, decision support and neutralization of micro- and mini-drones for sensitive sites and overseas deployments. The initial order covered six systems, with €33 million in firm commitments within a stated €350 million programme budget over 11 years. Operator training, maintenance and upgrades were included. The French defence procurement has officially notified Thales and CS GROUP to develop PARADE drone countermeasures system — Thales — Apr 2022

RAPIDFire supplies a heavier remotely operated cannon layer. The companies reported a French procurement contract covering 48 systems, including 14 naval installations, while the land variant remained developmental in June 2025. Thales and KNDS France unveil RAPIDFire Land, a land-based variant of the 40 mm RAPIDFire Naval defence system — Thales — Jun 2025

At the terminal level, the Benelli M4 A.I. Drone Guardian supplies a purpose-designed semiautomatic 12-gauge option. However, the publicly accessible manufacturer record does not confirm the reported delivery of 400 weapons to the French Army. That quantity should remain an attributed proposition pending a French procurement, budget or acceptance record.

France’s main design challenge is no longer identifying layers. It is connecting them. PARADE, naval and land RAPIDFire configurations, electronic attack and soldier weapons must operate from a shared air picture if the investment is to produce more than parallel local systems.

Germany: mobile protection around mechanized forces

Germany’s principal contribution is the return of mobile gun-based air defence to manoeuvre formations. The Skyranger 30 order covers one prototype and 18 production vehicles, with an option for 30 additional systems. Rheinmetall valued the order at €595 million including VAT, with delivery of the prototype planned ahead of the production fleet. Mobile air defence: Rheinmetall to supply the Bundeswehr with Skyranger 30 on Boxer platform – order worth almost €600 million — Rheinmetall — Feb 2024

The initial quantity cannot provide continuous coverage across the Bundeswehr. Germany will therefore need a hub-and-spoke structure: Skyranger nodes supplying higher-quality surveillance and cannon effects, while subordinate units retain passive detection, electronic countermeasures and terminal weapons.

The Bundeswehr’s own account recognizes both the need for a weapons mix and the danger of exhausting ammunition under mass drone attack. Its public concept also warns indirectly against premature mass acquisition of rapidly obsolescing drones, favouring close industry cooperation and scalable procurement when requirements mature. Drohnen und Drohnenabwehr in Deutschland und der Ukraine — Bundeswehr — Oct 2025

The resulting German priority should be integration of scarce Skyranger vehicles with broader passive and local-defence networks, not reliance on the Boxer fleet as a universal answer.

United Kingdom: financing the enabling architecture

The United Kingdom has disclosed unusually clear investment categories. Its 2026 Defence Investment Plan assigns £400 million to integrated air-and-missile-defence tactical command-and-control and sensing, more than £750 million to counter-drone capabilities including low-cost ground effectors, and £490 million to directed-energy weapons. The Defence Investment Plan — UK Ministry of Defence — Jul 2026

This balance is strategically important. It recognizes that sensing and command infrastructure require major investment alongside interceptors. The combination of DragonFire, radio-frequency directed energy, Falcon Shield-related industrial capability and low-cost ground effectors provides a diverse experimental base.

The risk is temporal and architectural. Several systems remain in demonstration, development or early delivery. If each enters service with a separate sensor and control arrangement, the United Kingdom will reproduce the fragmentation it is attempting to solve. Its 2031 test will be whether different effectors can compete for assignment from the same recognized track rather than whether each programme succeeds independently.

The European Union can shape markets but not command engagements

The European Commission’s February 2026 Action Plan on Drone and Counter-Drone Security covers detection, response, readiness, mass production and access to EU financing. It identifies Horizon Europe, the European Defence Fund, the European Defence Industry Programme and SAFE as relevant instruments. Commission publishes the Action Plan on Drone and Counter-Drone Security — European Commission — Feb 2026

The EU’s comparative advantage lies in aggregating demand, supporting production facilities, financing cross-border development and attaching conditions to funded procurement. It does not replace NATO’s military-standardization role or national authority over weapon employment.

The European Defence Industrial Strategy invites member states to procure at least 40% of defence equipment collaboratively by 2030, obtain at least 50% of defence procurement by value from the European defence industrial base by 2030, and raise intra-EU defence trade to at least 35% of the EU defence market. These are policy objectives, not achieved outcomes or legally guaranteed procurement shares. First ever defence industrial strategy and a new defence industry programme to enhance Europe’s readiness and security — European Commission — Mar 2024

Counter-drone procurement is particularly suitable for collaborative acquisition because the relevant consumables must be purchased in volume and replenished frequently. The Commission’s 2025 White Paper argues that collaborative procurement of ammunition, missiles and drones can aggregate demand, reduce costs and improve interoperability and interchangeability. It also proposed an air-defence initiative encompassing collective acquisition and accelerated production of short- and medium-range interceptors. White Paper for European Defence – Readiness 2030 — European Commission and High Representative — Mar 2025

The policy consequence is direct: EU financing for counter-drone programmes should reward demonstrable cross-vendor interoperability, multiple qualified ammunition suppliers and the ability to accept new effectors without replacing the command system.

Scaling artillery production provides a warning, not a direct solution

The Act in Support of Ammunition Production allocated more than €500 million across explosives, powder, shells, missiles, testing and reconditioning. Of this portfolio, approximately €248 million concerned powder, €124 million explosives, €90 million shells, €50 million missiles and €2 million testing and certification. The Commission expected supported investments to contribute to an annual European shell-production capacity of two million by the end of 2025. ASAP | Boosting defence production — European Commission

That declared capacity objective should not be treated as verified realized output, and 155 mm artillery capacity cannot be converted directly into counter-drone ammunition. The programme is nevertheless relevant because it identifies the deeper production bottlenecks: explosives, propellant, components, certification and predictable demand.

Counter-drone munitions add further constraints—electronic fuzes, miniature radars, programmable interfaces, batteries, seekers and processors. Europe could expand metalworking capacity while remaining dependent on a small number of suppliers for the electronic elements that make each round effective.

The lesson for 2031 is that nominal assembly capacity is insufficient. Readiness requires qualified suppliers for critical subcomponents, surge clauses, common acceptance procedures, strategic stocks and recurring orders large enough to keep production lines economically active.

The credible 2031 force

The most defensible outlook is a mixed architecture with five characteristics.

First, terminal counter-drone weapons will become normal equipment for selected combat groups, vehicle crews and installation guards. They will improve survival but will not constitute the primary defensive layer.

Second, battalions and brigades will receive more mobile cannon, interceptor and electronic-warfare capability, although procurement volumes will remain insufficient to cover every unit continuously. Networked allocation will therefore matter more than nominal inventory.

Third, sensor-to-effector interfaces will become an explicit procurement criterion. Progress will be uneven because states have existing proprietary systems and legitimate cybersecurity concerns. Full European standardization by 2031 is not supported by the present record; partial interoperability among priority national systems is achievable.

Fourth, ammunition families will diversify. Physical cartridges and cannon rounds will coexist with consumable interceptor drones and reusable electrical effects. Procurement authorities will need to measure magazine depth across all four categories rather than count only missiles or artillery rounds.

Fifth, Ukrainian operational experience and industrial participation will influence European requirements. The EU White Paper expressly identifies Ukrainian expertise in drones and artificial intelligence as relevant to European capability development and proposes deeper integration of the Ukrainian defence industry. White Paper for European Defence – Readiness 2030 — European Commission and High Representative — Mar 2025

Indicators and decision thresholds

Indicator	Direction supporting the assessment	Warning threshold
Sensor–effector interoperability	Multinational trials generate successful engagements using another supplier’s track	Systems can share awareness data but still require proprietary fire-control sensors
Distribution	Counter-UAS equipment becomes organic below brigade level	Capability remains confined to specialist air-defence and base-protection units
Ammunition scale	Multi-year multinational contracts include surge and second-source provisions	Repeated small national orders produce incompatible variants
Directed-energy maturity	Operational units publish sustained deployment and availability records	Performance remains confined to controlled demonstrations
Interceptor economics	Audited cost per confirmed defeat falls while production and stock depth rise	Low unit prices conceal dependence on scarce seekers, batteries or imported electronics
Human–machine control	Automated tracking and assignment shorten engagement time while retaining clear authority	National rules prevent coalition systems from acting on shared tracks
Industrial resilience	Fuzes, propellants, tungsten loads, processors and motors have multiple qualified sources	Final assembly expands while critical subcomponents remain single-source

Key judgments

• Europe has enough candidate effectors to construct a credible layered defence; fragmentation of demand, interfaces and ammunition is the controlling weakness.
• Counter-drone protection must become distributed, but complete radar-directed systems cannot be issued universally. The sustainable model distributes observation and terminal defence while networking scarce high-quality sensors and effectors.
• France is developing the broadest visible vertical set of layers; Germany emphasizes mobile cannon protection; the United Kingdom is investing heavily in sensing, command and directed energy; Italy has significant integration capability but no publicly established force-wide mobile kinetic architecture.
• The EU can improve scale through financing, joint procurement and supply-chain policy. NATO remains the more appropriate framework for military interoperability, testing and coalition employment.
• A common interface is more attainable and more valuable than a single European counter-drone weapon.
• Ammunition readiness must include cartridges, programmable rounds, interceptor drones and electrical-system capacity. Artillery-shell production figures do not measure counter-drone magazine depth.
• The credible objective for 2031 is partial but operational interoperability among layered national systems, not a uniform European shield.

What would change the assessment

The assessment would strengthen if NATO publishes a certified sensor-to-effector interoperability profile, if EU-funded procurement makes compliance mandatory, and if multinational exercises demonstrate cross-national engagements rather than simple co-location of systems.

It would weaken if governments continue purchasing closed national chains, if programme schedules expand platform numbers without corresponding ammunition contracts, or if critical fuze, seeker, battery and propellant components remain dependent on single suppliers.

Evidence that low-cost passive sensors can consistently produce cannon-quality tracks would materially accelerate distribution. Conversely, operational evidence that programmable ammunition performs poorly against rapidly manoeuvring FPV drones would shift investment toward interceptors, directed energy and denser terminal defence.

Open official record

• No public NATO record yet defines a complete, certified European interface covering detection, track quality, weapon assignment, engagement authorization and damage assessment for counter-UAS operations.
• National inventories, mission-capable rates and ammunition holdings for European counter-drone systems remain predominantly non-public.
• Italy has not published a sufficiently detailed force-wide roadmap connecting ACUS, mobile sensors, electronic attack and kinetic effectors through 2031.
• France has not published a consolidated architecture showing how PARADE, RAPIDFire, soldier weapons and other national systems will exchange target-quality tracks.
• Germany has not disclosed how many lower-level units will receive organic counter-drone sensors and effectors around the initial Skyranger fleet.
• The United Kingdom has published investment envelopes but not a complete delivery schedule, system allocation or common-interface standard for all funded counter-drone programmes.
• The European Commission’s two-million-shell objective described expected annual capacity, not independently verified production, deliveries or counter-drone ammunition availability.
• Comparable official data remain unavailable for cost per defended area, simultaneous engageme
