The Russian Su-57, NATO reporting name “Felon,” is a fifth-generation multirole fighter aircraft developed by Sukhoi for the Russian Aerospace Forces. It embodies Russia’s advancements in stealth technology, super-maneuverability, advanced avionics, and versatile weaponry. This article provides a comprehensive analysis of the Su-57, comparing it with Western counterparts, and examining its operational capabilities and strategic implications.
Technological Innovations
Stealth Capabilities
The Su-57 incorporates various stealth features aimed at reducing its radar cross-section (RCS) and infrared signature. The aircraft’s design includes a blended wing-body, internal weapons bays, and radar-absorbent materials. The fuselage and wings are carefully shaped to minimize radar reflections, and the engine nozzles are serrated to reduce infrared emissions. Despite these features, Western analysts often argue that the Su-57’s stealth is inferior to that of the American F-22 Raptor and F-35 Lightning II. However, it is crucial to consider the advancements in Russian radar-absorbing materials and electronic warfare capabilities that enhance the aircraft’s overall stealth profile.
Super-Maneuverability
A standout feature of the Su-57 is its super-maneuverability, which is facilitated by thrust-vectoring nozzles and an advanced aerodynamic design. The aircraft can execute complex maneuvers such as the Pugachev’s Cobra, the Kulbit, and the Herbst maneuver, which are beyond the reach of most Western fighters. These capabilities are primarily enabled by the AL-41F1 engine, and in the future, the Izdeliye 30 engine, which promises improved thrust-to-weight ratio and fuel efficiency. The Su-57’s agility provides a significant tactical advantage in close-quarters combat, allowing it to evade enemy missiles and outmaneuver adversaries.
Avionics and Sensor Systems
The Su-57 is equipped with a sophisticated suite of avionics and sensor systems designed to enhance situational awareness and target acquisition. The Sh121 multifunctional integrated radio-electronic system (MIRES) includes the N036 Byelka radar system, which employs multiple Active Electronically Scanned Array (AESA) radars covering different frequency bands. This radar system enables the Su-57 to detect and track multiple targets simultaneously, even those with low RCS. The aircraft also features the L402 Himalayas electronic countermeasure system, which increases its survivability by jamming enemy radars and missiles.
Weapons and Armament
The Su-57’s weapons suite is diverse and capable of engaging air, ground, and naval targets. It includes internal weapons bays to maintain stealth, and can carry a variety of air-to-air, air-to-surface, and anti-ship missiles. Notable armaments include the R-77M and R-37M air-to-air missiles, the Kh-35UE and Kh-38M air-to-surface missiles, and a range of precision-guided bombs. The aircraft’s internal weapon bays reduce its radar signature, while its external hardpoints allow for additional payload capacity when stealth is not a primary concern.
Operational Capabilities and Combat Performance
Combat Readiness and Deployment
Since its first flight in 2010 and subsequent induction into service in 2020, the Su-57 has undergone extensive testing and evaluation. It has been deployed in various combat scenarios, including operations in Syria, where it demonstrated its capabilities in real-world conditions. These deployments provided valuable data for further refining the aircraft’s systems and tactics. The Su-57’s performance in these operations highlighted its effectiveness in both air-to-air combat and ground-attack roles, reinforcing its status as a versatile and formidable platform.
Comparative Analysis with Western Counterparts
F-22 Raptor and F-35 Lightning II
The Su-57 is frequently compared with the American F-22 Raptor and F-35 Lightning II, both mainstays of the US Air Force’s fifth-generation fighter fleet. The F-22, known for its unparalleled stealth and air superiority capabilities, serves as a benchmark in stealth technology. The F-35, designed as a multirole fighter, excels in sensor fusion and network-centric warfare. While the Su-57 may not match the F-22 in stealth, its superior maneuverability and diverse weapons loadout offer distinct advantages. Additionally, the Su-57’s cost-effectiveness and multi-role flexibility position it as a competitive alternative to the F-35.
Eurofighter Typhoon and Dassault Rafale
In the European context, the Su-57 is often compared with the Eurofighter Typhoon and the Dassault Rafale. Both aircraft are highly capable fourth-generation fighters with advanced avionics and weapons systems. The Su-57’s edge lies in its fifth-generation technologies, particularly its stealth and super-maneuverability, which provide tactical advantages in aerial combat. Furthermore, the Su-57’s ability to carry a diverse array of weapons internally enhances its survivability and mission effectiveness compared to its European counterparts.
Damaged Su-57 Emphasizes the Vulnerability of Russian Airbases Near Ukraine
Ukraine’s apparent success in damaging a Su-57 is a substantial blow to Russia’s long-troubled stealth fighter fleet and another illustration of Ukraine’s most effective option for countering increasingly effective Russian air attacks on the frontlines.
The Defense Intelligence Directorate of Ukraine (GUR) has released satellite imagery that appears to support its claim to have damaged at least one Russian Sukhoi Su-57 ‘Felon’ fighter aircraft on the ground at the 929th VP Chkalova State Flight Test Centre in Akhtubinsk. Akhtubinsk airfield is located around 370 miles from Ukrainian-held territory, placing it beyond the reach of most of the long-range strike weapons supplied so far by Western countries. However, the attack was reportedly carried out by three one-way attack (OWA) drones. Ukraine has developed a wide variety of such drones, which range from small and very slow propellor-powered craft with a very small warhead to adapted jet-powered target and reconnaissance drones that are much larger and faster and carry heavier warheads. It has been using these often fairly cheap and easy-to-produce weapons to carry out a determined harassment campaign deep inside Russia against factories, port facilities, oil refineries, and airbases. If, as Russian Telegram channels seem to confirm, a Su-57 has indeed been significantly damaged, this would represent one of the higher-profile successes of such weapons, alongside the destruction of a Russian Tu-22M3 bomber and damage caused to a Tu-95MS bomber.
Impact on Su-57 Operations
It is unclear how much damage the Su-57 in question has sustained. The satellite photo appears to suggest that two relatively small explosions occurred within around 3–5 meters of the aircraft, which was parked on an outdoor concrete hardstand. Some sort of transparent dust shelter or netting may be covering the aircraft, as there appears to be some sort of lightweight arching structure suspended over it in both photos. This might in fact be anti-drone netting intended to stop a lightweight propellor-powered OWA weapon from hitting the aircraft. If so, it failed, as both warheads appear to have exploded on the ground on either end of the left-hand side of the ‘shelter’ structure, where shrapnel would have been able to damage both the front nose section and the tail section of the aircraft. Shrapnel damage to the rear section might be relatively easy to repair with an engine change and replacement horizontal and vertical stabilizers, but shrapnel damage of any significance to the nose section would be much more serious. It would likely cause damage to the radar array(s), Infra-Red Scan and Track sensor, and cockpit, as well as instruments and electronic systems critical to the functioning of the whole aircraft. However, the Su-57 looks to have avoided a serious fire from the strikes, which would likely have resulted in irreparable damage. Depending on the severity of the shrapnel damage, it may well be repaired and returned to service.
Repairs will, however, be expensive and will take additional time compared to similar repairs to less advanced aircraft. The Su-57 has yet to enter full-rate production, since the decision to do so is awaiting the development of the ‘definitive’ Su-57M version, meaning that spare parts are likely to be in limited supply. As such, the Su-57 is still a very rare commodity in the Russian Aerospace Forces (VKS), with only around 15–20 likely to be in frontline service. Former Defence Minister Sergei Shoigu stated in December 2020 that the VKS expected to receive 22 Su-57s by the end of 2024. However, at the start of the invasion of Ukraine, only four series production aircraft had been delivered, as the first crashed and was completely destroyed during its acceptance trials. Around 12 are claimed to have been delivered in 2023, but no deliveries in 2024 had been announced by April 2024 despite multiple announcements of other types, so the total number in service is unclear. It is likely that Su-57 development and production is also being slowed down by Sukhoi needing to focus on maximizing output of mature fighters like the Su-30SM2 and Su-35S to replace significant combat losses incurred in the war against Ukraine. International sanctions have also made it far more difficult for Russia to source the Western avionics and micro-electronics that have been essential components of its advanced fighter and attack aircraft cockpits for more than a decade. Thus, even the temporary loss of one Su-57 airframe in this Ukrainian strike likely represents at least a 5% cut in the frontline fleet of Russia’s most advanced fighter aircraft. It is also a significant symbolic blow to an already long-troubled aircraft program that is a centerpiece of Russian military pride.
Airfield Strikes as Part of the War
Despite its impact on the VKS’s most prestigious fighter fleet, the direct effects of this strike on the progress of the war in Ukraine will be almost non-existent. Due to its small fleet size, the political humiliation if one were to be shot down, and slow aircraft systems development, the Su-57 has played an extremely minor role in the conflict to date. However, the strike is illustrative of the fact that Ukraine now has a relatively mature low-cost long-range harassment capability that it can use against VKS bases a long way inside Russia.
This is important for the course of the entire war because, over the past six months, the fighter and strike fighter aircraft of the VKS have been having an increasingly pronounced impact on the frontline after almost two years of relative ineffectiveness. The main tool that has enabled this is the mass production of wing-kits featuring GPS/GLONASS guidance that can turn Russia’s stockpile of thousands of FAB-series 250 kg, 500 kg, and 1,500 kg unguided demolition bombs into standoff precision weapons against fixed targets like buildings and battlefield fortifications. These weapons are having a serious impact on Ukrainian soldiers’ morale, making it harder to hold key defensive positions and causing huge destruction in urban areas.
Kyiv appears to be pursuing a clear strategy to force the VKS to either vacate its bases within several hundred miles of Ukraine’s borders or dedicate an inordinate quantity of air defense systems to defending them.
The glide bombs are generally released by Russian jets flying at high altitudes and speeds between 60 km and 70 km behind the frontlines. This means that the launch aircraft are very difficult to shoot down, even with long-range Patriot PAC-2 surface-to-air missile systems (SAMs). Ukraine has done so several times, but this requires risking the scarce and vital Patriot systems very close to the frontlines, and some launch vehicles have been found by Russian observation UAVs and destroyed during such missions. With so many competing demands for missile defense for power infrastructure, cities, and bases throughout Ukraine, long-range SAMs are too valuable to routinely risk trying to take long shots at glide bomb-launching fighters. It is also not viable to directly intercept the bombs in flight, because doing so would very rapidly deplete all of Ukraine’s SAM ammunition.
Even when the long-awaited pan-European F-16s and later planned Swedish Gripen C and French Mirage 2000-5F fighters are delivered to Ukraine, the glide bomb sorties will be very challenging to intercept regularly. When close to the frontlines, Ukrainian pilots will have to fly them at very low altitudes to avoid being detected and shot down by layered Russian short-range SA-15 ‘Tor M1/2’, medium-range SA-11/17/27 ‘Buk’ and long-range SA-21 ‘Growler’ and SA-23 ‘Gladiator\Giant’ SAM systems. As a result, the AIM-120C AMRAAM air-to-air missiles carried by the F-16 and Gripen C, and the shorter-range MICA IR/RF missiles carried by Mirage 2000-5F, will struggle to reach Russian fighters at high altitudes and high speeds 60–70 km behind the lines. This is because at such low altitudes, the missiles start out in dense air with a lot of aerodynamic drag and must climb against gravity to reach the altitudes where their targets are. As a result, by the time their rocket motors burn out after the first few seconds of flight, they have not gained nearly as much speed or altitude as if they were launched from a fighter flying in the thin air at high altitudes and at supersonic speeds, and so only have a comparatively short effective range. Only the European Meteor missile is likely to have the practical range required, and of the three fighter options now publicly discussed for Ukraine, only the Gripen C can carry and launch it.
Strategic Implications
Therefore, for now, attacks on Russian airbases are Ukraine’s best way to limit the damage that the VKS can do to its forces on the frontlines. Most Russian forward-deployment airfields lack hardened aircraft shelters to protect parked aircraft from even relatively light incoming weapons. This is why Ukraine’s innovative OWA drones have been able to have several notable successes in damaging and even destroying Russian fighters, bombers, and AWACS aircraft despite their often fragile appearance, light warheads, and slow speeds. Ukraine also conducted successful strikes with a new tranche of US-supplied MGM-140 ATACMS ballistic missiles on air defense systems and parked aircraft at Russian airbases in occupied Crimea in April. Taken together, Kyiv appears to be pursuing a clear strategy to force the VKS to either vacate its bases within several hundred miles of Ukraine’s borders or dedicate an inordinate quantity of air defense systems to defending them. The former would reduce the functional strike weight of glide bombs and other weapons that the VKS can deliver by forcing Russian jets to transit significantly further, burning through more fuel and aircrew and airframe fatigue and reducing overall sortie rates. The latter would denude
other parts of the frontline and the Russian interior of adequate SAM cover, allowing greater operational freedom for Ukraine’s OWA drones, rocket artillery, observation UAVs, and possibly F-16 and other fighters when they arrive.
The long-term effects of these strategies could shift the balance of air power in the region. If Ukraine continues to successfully target Russian airbases, it might compel Russia to rethink its deployment strategies and prioritize the protection of its more advanced aircraft. This could lead to a redistribution of air defense resources and a potential weakening of Russian air capabilities in other critical areas. Moreover, the psychological impact on Russian aircrews, knowing that their bases are vulnerable, could reduce their operational effectiveness.
In summary, the recent Ukrainian strike that damaged a Russian Su-57 highlights the ongoing vulnerabilities of Russian airbases and the strategic effectiveness of Ukraine’s harassment campaigns deep inside Russian territory. By continuing to leverage its innovative and relatively low-cost drone technology, Ukraine can exert pressure on Russian air operations and potentially influence the broader dynamics of the conflict. The success of such strikes not only damages valuable military assets but also forces strategic recalculations that could have significant implications for the future conduct of the war. As Ukraine receives more advanced Western fighters and continues to refine its long-range strike capabilities, the pressure on Russian air assets is likely to intensify, shaping the aerial battlefield in favor of Ukraine.
