ABSTRACT
Statements by Donald Trump on September 30, 2025 at Marine Corps Base Quantico proposing a return to gun-centric, heavily armored “battleships,” and references to consultations with Secretary of the Navy John Phelan, require immediate scrutiny grounded in official documentation and current program realities. Public-record confirmation of the Quantico event and policy signaling appears in contemporaneous reporting and statements from ABC News on September 30, 2025 and CBS News on September 30, 2025, which document an unprecedented gathering of senior flag officers addressed by President Donald Trump and Defense Secretary Pete Hegseth at Quantico and the administration’s intent to redirect force-development priorities (ABC News, September 30, 2025; CBS News, September 30, 2025). The official leadership status of John Phelan as 79th Secretary of the Navy is verified by Navy.mil with a sworn-in date of March 25, 2025 (U.S. Navy, Leadership Bio). The specific claim that “battleships” are under consideration sits against the technical baseline of the U.S. Navy’s current and prospective surface-combatant portfolio, especially DDG-1000 modernization for Conventional Prompt Strike (CPS) and DDG(X) pre-acquisition design studies, as reflected in official fact files and program-office communications (U.S. Navy Fact File: DDG-1000; Naval News, January 12, 2025).
The last Iowa-class battleships (USS Iowa, USS New Jersey, USS Missouri, USS Wisconsin) were decommissioned between 1990 and 1992 and subsequently converted to museum ships after periods on or off the Naval Vessel Register, as documented by the Naval History and Heritage Command (NHHC: USS Iowa; NHHC: USS Iowa (BB-61)). The manpower and lifecycle burden of such platforms are material to feasibility: the Iowa-class required crews in excess of 1,500—more than 5 times that of a Flight IIA Arleigh Burke-class destroyer—amplifying recruiting, training, and operations-and-support costs now under sustained pressure across the fleet. While precise manning tables differ by configuration and year, the broad differential is uncontested in official and scholarly sources; no verified public source provides current 2025 detailed manning plans for any hypothetical recommissioning—No verified public source available.
On lethality and reach, the central empirical contrast remains between large-caliber guns and modern missiles. The U.S. Navy’s post-Cold War experience with naval gunfire support converged on the 155 mm Advanced Gun System (AGS) on DDG-1000, contingent on the Long Range Land-Attack Projectile (LRLAP). The ammunition’s per-round cost escalated into the $800,000–$1,000,000 band before procurement was halted in 2016, leaving AGS without operational ammunition; the decision chain and cost data are recorded in contemporaneous defense reporting and analyses that cite Navy documentation (Defense News, November 6, 2016; Ars Technica, November 7, 2016). Parallel lines of effort migrated to Conventional Prompt Strike (CPS) integration on DDG-1000, verified in U.S. Navy fact files and subsequent program updates in 2023–2025, including USNI News reporting on missile-tube installation milestones on January 15, 2025 (U.S. Navy Fact File: DDG-1000; USNI News, January 15, 2025). Evidence for an evolving design philosophy that may even omit a forward main gun in some DDG(X) renderings appears in January 2025 coverage citing the DDG(X) Program Office presentation (Naval News, January 12, 2025).
Regarding railguns, the official analytic baseline is set by the Congressional Research Service (CRS)’s longitudinal report “Navy Lasers, Railgun, and Gun-Launched Guided Projectile”, updated September 11, 2025, which details the program’s evolution, test history, funding decisions, and the migration of effort toward hypersonic weapons (CRS R44175, September 11, 2025; CRS R44175, September 11, 2025). Additional confirmation that the U.S. Navy halted railgun development funding lines in the early 2020s to prioritize other capabilities appears in official-source-based reporting and service statements (Military.com, July 2, 2021). The cost premise often cited in railgun discourse—that guided projectiles could, at maturity, undercut missile price points—coexisted with unresolved technical hurdles in power systems, barrel life, thermal management, and fire-control integration documented in the CRS series. As of 2025, no U.S. Navy program of record fields a shipboard railgun; No verified public source available for any current 2025 fleet introduction timeline.
Armor and materials policy in surface combatants present an additional vector of analysis. Persistent cracking issues on aluminum-intensive designs have been documented by the Government Accountability Office (GAO) and the Director, Operational Test & Evaluation (DOT&E) in the Littoral Combat Ship (LCS) program, with weld-cracking and structural concerns observed in trials and survivability assessments (GAO-16-201, December 18, 2015; GAO PDF excerpt). The observed outcomes influenced subsequent U.S. Navy preferences for all-steel superstructures in follow-on designs, while broader survivability and modernization weaknesses in large surface combatants—particularly Ticonderoga-class cruisers—have been criticized by GAO in December 2024, highlighting schedule slips, cost growth, and quality-control gaps in cruiser modernization that are germane to any proposal to reintroduce unusually large and complex ships (GAO-25-106749, December 17, 2024).
Strategic utility and opportunity cost in 2025 hinge on adversary anti-access/area-denial envelopes, magazine depth, and the integration of hypersonic, supersonic, and subsonic missile families with cooperative engagement networks. The U.S. Navy’s current trajectory—retiring Ticonderoga-class cruisers while attempting to ramp DDG-51 Flight III production and define DDG(X)—prioritizes vertical launch capacity, sensor reach, and power margins for directed energy and future effectors. The empirical program evidence for this course is visible in CPS integration timelines, DDG(X) concept studies, and FY budget documentation summarized in CRS reports through September 2025 (CRS R44175, September 11, 2025).
Recommissioning Iowa-class hulls now faces compounded constraints relative to 2006–2007, when legislative provisions still contemplated recall under extraordinary conditions; since transfer to museum status, the bar for technical regeneration has risen. Steam-plant rehabilitation, magazine safety compliance under current ordnance standards, and the reacquisition of 16-inch supply chains—all absent from the FY program portfolio—would involve multi-year, multi-billion-dollar undertakings with high technical risk. No authoritative 2025 cost estimate exists in public for full return-to-service—No verified public source available.
Claims that “bullets are cheaper than missiles” are arithmetically true on a per-round basis but analytically incomplete without considering operational reach, time-to-kill in contested environments, probability of raid annihilation, and defensive resource depletion. The U.S. Navy’s abandonment of LRLAP in 2016 at $800,000–$1,000,000 per round and redirection to CPS illustrate the decisive role of range and lethality-per-shot in contemporary naval combat calculus (Defense News, November 6, 2016; Ars Technica, November 7, 2016). Conversely, the CRS record shows why hopes for railgun-grade cost-per-shot have remained unrealized at sea, reinforcing the missile-centric path while leaving room for future gun-technology inflection if and when technical blockers are removed (CRS R44175, September 11, 2025).
Force-design debates about armor remain salient given the demonstrated lethality of one-way attack UAS and anti-ship cruise and ballistic missiles observed in Red Sea combat incidents since 2023–2024; official open-source summaries repeatedly note magazine-management stress on surface escorts under sustained attack. However, authoritative 2025 design documentation for passive armor increases on new U.S. Navy large combatants is not publicly released—No verified public source available for any finalized requirement. The available modernization evidence emphasizes active defense layers, sensor fusion, and long-range strike integration alongside survivability upgrades within weight and power constraints consistent with existing shipyards’ capacity and the industrial base’s current throughput (see GAO-25-106749 for cruiser modernization lessons learned on quality and schedule risk: GAO, December 17, 2024).
Institutionally, the policy environment since January 2025 features assertive civilian guidance. The Department of the Navy leadership structure is official as of March 25, 2025 (U.S. Navy, Phelan Bio). Administration-level direction and agenda-setting rhetoric to the armed forces are documented in network-news reporting contemporaneous with the September 30, 2025 Quantico session—supporting the factual premise that senior leaders raised, in public fora, preferences that could influence requirements and acquisition pathways (ABC News, September 30, 2025; CBS News, September 30, 2025). The narrow proposition of reintroducing “battleships,” however, conflicts with the documented trajectory of the U.S. Navy’s major surface combatant programs through 2025, which emphasize VLS capacity, integrated power for next-generation sensors and effectors, and hypersonic-class strike on a limited number of high-end platforms, rather than newbuild gun-centric capital ships (U.S. Navy Fact File: DDG-1000; Naval News, January 12, 2025).
Finally, the industrial-base and schedule context is adverse to any very-large-ship reintroduction. Public testimony and open-source oversight have chronicled chronic delays and cost growth across multiple programs; GAO’s December 2024 cruiser report enumerates quality-control shortfalls that would scale unfavorably on a platform class larger and more manpower-intensive than any in present production (GAO-25-106749, December 17, 2024). In addition, official U.S. Navy modernization releases and USNI News program coverage indicate that limited shipyard capacity is already committed to CPS conversions, DDG-51 Flight III, Virginia-class/Columbia-class submarine backlogs, and amphibious-ship sustainment. No authoritative 2025 industrial-base plan publicly allocates capacity to reintroduce an armored, gun-centric capital ship—No verified public source available. In sum, while public remarks by Donald Trump and the position of Secretary John Phelan ensure the idea enters bureaucratic consideration, the authoritative technical, fiscal, and programmatic record through September 2025 points toward continued missile-centric surface warfare, selective exploration of next-generation projectiles within conventional guns, and survivability enhancements that do not replicate historical “battleship” constructs.

Decoding Naval Power—Key Insights on Battleships, Armor, Missiles, Drones, and America’s Actual Fleet Plans
Guns on ships are useful for short to medium distances, but modern naval combat mainly uses guided missiles because they reach far targets with high accuracy. The Congressional Research Service Navy DDG-51 and DDG-1000 Destroyer Programs, March 21, 2025 explains that today’s large United States surface warships center their design around missile launch cells that can fire different types of weapons for air defense, ship-to-ship combat, and land attack. The Congressional Budget Office An Analysis of the Navy’s 2025 Shipbuilding Plan, January 6, 2025 confirms that current ship plans and costs reflect this missile-centric approach rather than a return to gun-centric ships.
A “battleship” is a very large warship with heavy armor and large guns. The United States has not operated battleships for active duty since the early 1990s. The Naval History and Heritage Command shows that the last four battleships of the Iowa class were decommissioned by 1992 and are now museum ships in different cities, as summarized on its leadership and history pages and in the historical profile for USS Iowa Admiral Frank B. Kelso II biography page, July 15, 2016 and the detailed ship evaluation posted by Naval Sea Systems Command Naval Vessel Historical Evaluation, 2011. These official records confirm the end of United States battleship service and the change to modern fleets focused on carriers, submarines, and guided-missile surface ships.
Very large gun ships would need very large crews, complex maintenance, and specialized parts that are no longer made at scale. The Government Accountability Office found that the Navy already faces serious challenges maintaining and modernizing its current large surface warships, with cost growth, delays, and quality problems on cruiser overhauls. See the Government Accountability Office Navy Ship Modernization, GAO-25–106749, December 17, 2024. The Congressional Budget Office analysis cited above shows that the Navy’s budget must cover many competing needs, including submarines and missile ships, which makes adding a brand-new class of very large gun ships even harder.
Modern destroyers and cruisers rely on missile cells because one launcher can hold many weapon types. The United States Navy fact file on DDG 1000 Zumwalt-class shows how design priorities have shifted. Although these ships were built with advanced 155 millimeter guns, the Navy did not buy the planned long-range shells because of very high costs. The Navy is now converting the ships to carry hypersonic missiles. See the United States Navy DDG 1000 Zumwalt-class Destroyer Fact File, January 5, 2023 and Naval Sea Systems Command coverage of hypersonic integration milestones in the May 8, 2024 event with INDOPACOM and STRATCOM leaders. The Congressional Research Service report on destroyer programs also tracks these changes in mission and fit, again confirming the move toward long-range missiles over large naval guns. See Navy DDG-51 and DDG-1000 Destroyer Programs, March 21, 2025.
People often ask whether cheaper gun ammunition could replace expensive missiles. The price per shell can be lower, but range and precision are different. The Congressional Research Service explains that long-range guided shells for ship guns became so costly that the program was stopped, while guided missiles remained the main option for long-range strikes and air defense. See the Congressional Research Service Navy Lasers, Railgun, and Gun-Launched Guided Projectile, December 9, 2020. That report also describes how a new type of guided shell could be fired from standard 5 inch guns, but the Navy’s shift toward hypersonic and other missiles shows where the money and engineering are going today.
Armor is another common question. Older battleships used thick steel belts to block shells and older missiles. Today’s ships use a mix of steel and lighter materials in different parts of the hull and superstructure to reduce weight and cost. Structural issues in some aluminum superstructures from past ship classes required repairs and changes in designs. Naval Sea Systems Command documented methods developed at its labs to fix aluminum cracking on cruiser superstructures, which influenced later decisions to emphasize steel in many designs. See Naval Sea Systems Command Carderock composite patch repair for aluminum cracking on cruiser superstructures, August 12, 2019. The Government Accountability Office has repeatedly highlighted the need to improve ship maintenance, planning, and quality controls across the surface fleet. See Navy Ship Modernization, GAO-25–106749, December 17, 2024 and shipyard infrastructure findings in Shipyard Infrastructure Optimization Program, GAO-23–106067, June 28, 2023.
Real-world combat now includes frequent drone and missile attacks at sea. In the Red Sea and nearby waters, United States forces have intercepted many drones and missiles since late 2024. These official updates show the kind of high-volume, multi-threat environment modern ships face, which stresses air defenses and missile magazines. See U.S. Central Command December 10, 2024 release on defeating Houthi attacks and February 24, 2025 release on joint strikes against Houthi targets. These official reports demonstrate why current ships carry a mix of long-range missiles, medium-range interceptors, close-in defenses, and electronic warfare rather than relying on big guns at short range.
The Navy’s next large surface combatant is being defined now. The working name is DDG(X). The analytic focus is power, cooling, sensors, and missile capacity. A recent Congressional Research Service brief explains the basic goals and trade-offs, including replacing retiring cruisers’ air-defense capacity and making room for future high-energy weapons. See Congressional Research Service Navy DDG(X) Next-Generation Destroyer, August 7, 2025. Naval Sea Systems Command maintains public material and technical venue slides that show the Navy’s design studies. See NAVSEA DDG(X) program material, January 2022. These sources make clear that the Navy is planning for ships with large power margins and modern sensors, not for a return to heavy-armor, heavy-gun platforms.
Hypersonic missile integration is moving forward on the Zumwalt-class. The Navy has shifted homeporting to support the conversion work and has posted official photos and releases that show launcher installation progress. See United States Navy Zumwalt arrives in Pascagoula for modernization, August 2, 2023 and Naval Sea Systems Command Hypersonics facility visit, May 8, 2024. This confirms that Navy investment is going into long-range, high-speed strike systems.
Several official budget documents show where money is going. The Department of the Navy requested $257.6B in the 2025 President’s Budget, as stated in the Navy’s own press release and budget pages. See United States Navy Department of the Navy FY 2025 President’s Budget, March 11, 2024 and Secretary of the Navy Financial Management and Comptroller FY 2025 Highlights Book, February 29, 2024. The Congressional Budget Office report linked earlier analyzes the long-term ship plan against these funding levels. These sources do not include any funded program to restart battleship construction.
Railgun technology was explored for many years, and some testing milestones were achieved, but the Navy did not field an operational ship railgun. The Congressional Research Service report on lasers, railguns, and guided projectiles cited above describes the funding path and remaining challenges. The Office of Naval Research has public material on earlier railgun demonstrations and media advisories that confirm significant test shots and outreach, showing progress in experiments but no fleet introduction. See Office of Naval Research Navy Sets New World Record With Electromagnetic Railgun Demo, December 10, 2010. Together, these official sources show that research continues in related areas, such as guided projectiles for existing guns and high-energy lasers, rather than a near-term railgun deployment.
The People’s Republic of China continues to expand its navy and missile forces, which shapes United States planning. The official Department of Defense annual report to Congress details the growth in Chinese ship numbers, missile inventories, and doctrine. See Department of Defense Military and Security Developments Involving the People’s Republic of China 2024, December 18, 2024 and the companion fact sheet, December 18, 2024. These documents, combined with Navy and Congressional Research Service sources, explain why United States surface ship plans prioritize air defense, long-range strike, and networked sensors over large-caliber guns and thick armor.
For citizens and officials who want to understand future destroyers, a simple point is that the Navy needs ships that can power advanced radars, computers, and directed-energy systems, and carry many missile cells. That is why the DDG(X) concept emphasizes power generation and cooling. The Congressional Research Service Navy DDG(X) Next-Generation Destroyer, August 7, 2025 notes power growth margins and integrated power systems as key design factors. The Navy’s technical slides show studies of hull form, sensors, and launch capacity rather than heavy, belt-style armor or very large gun turrets. See Naval Sea Systems Command DDG(X) program material, January 2022.
Cost and schedule risks are real. The Government Accountability Office has pointed to recurring problems in Navy shipbuilding and maintenance, which consume time and money and reduce fleet availability. See Government Accountability Office Navy Ship Modernization, GAO-25–106749, December 17, 2024. The Congressional Budget Office examined the gap between planned ships and funding levels, reinforcing that trade-offs are necessary. See An Analysis of the Navy’s 2025 Shipbuilding Plan, January 6, 2025. These constraints make it unlikely that the Navy would add a new battleship program alongside already hard choices on submarines, carriers, and missile ships.
Materials choices involve trade-offs. Aluminum can save weight but needs careful design and maintenance to handle cracking and heat. Steel adds strength and heat resistance but adds weight. Naval Sea Systems Command reported bonded composite patches to repair aluminum cracking on cruiser superstructures, which is one example of how the Navy solves issues in service rather than redesigning whole ships around heavy armor belts. See Carderock composite patch repair, August 12, 2019. Maintenance standards and corrosion control remain critical across steel and aluminum structures. See the Naval Sea Systems Command coating standard item used in ship work packages NAVSEA Standard Item 009–32, March 12, 2024 and training material on corrosion control in regional maintenance centers July 2023 edition.
Operational lessons from recent events are direct and clear. Drones and cruise missiles can be launched in waves, sometimes mixed with other weapons. Intercepting them can take many defensive shots. The official U.S. Central Command updates cited earlier are reliable examples. They show why navies around the world, including the United States, are investing in layered defenses and electronic warfare. Short-range guns still matter for close defense, but they are part of a larger system that starts with long-range sensors and interceptors. The Navy’s missile cells let a ship load the right mix for a mission and threat, which large guns cannot replace at long ranges.
Research continues on technologies that could change costs and magazine depth in the future. Guided projectiles for existing guns and high-energy lasers are two examples. The Congressional Research Service report on lasers and projectiles explains potential benefits and limits and notes that moving from demonstrations to fleet-ready systems takes time and stable funding. See Navy Lasers, Railgun, and Gun-Launched Guided Projectile, December 9, 2020. The Department of the Navy budget documents show continuing investment in research and development across these areas. See Secretary of the Navy Financial Management and Comptroller FY 2025 RDT&E Justification Books, March 2024 volumes.
For elected officials, the key policy facts are straightforward. Building new heavy-armor, heavy-gun ships would require very large budgets, new supply chains, new training pipelines, and many sailors at a time when crew recruiting is tight and current ship programs already strain budgets. The official budget and analytic sources above show no funded move in that direction. Current plans focus on destroyers with larger power margins, upgraded air defense radars, and many missile launch cells, plus conversions to carry hypersonic weapons. These choices match recent combat conditions and the official threat assessments for the People’s Republic of China, as documented in the Department of Defense annual report to Congress 2024 edition, December 18, 2024.
For ordinary citizens, the main point is that modern naval combat depends on information, networks, and layered defenses. Big guns help at closer ranges, but missiles and advanced sensors decide most engagements. Armor matters, but making an entire ship as heavily armored as a World War II-era battleship would reduce speed, reduce payload flexibility, and require far more people and money. The Navy addresses survivability with a combination of design, active defenses, redundancy, and tactics. The sources linked above are official and public and provide the best available evidence up to September 2025.
For social media users, a quick rule of thumb is that claims about bringing back battleships should be checked against official plans and budgets. The Navy’s public budget pages and the Congressional Budget Office and Congressional Research Service reports linked here show what is actually funded and built. There is no funded program to add battleships. The focus is on destroyers with strong air defense, submarines, and long-range strike.
For state and local leaders, the industrial base issues are real. Shipyard upgrades, skilled labor, and supplier capacity directly affect delivery schedules. The Government Accountability Office report on cruiser modernization problems GAO-25–106749, December 17, 2024 and the Congressional Budget Office 2025 shipbuilding analysis both point to the need for steady funding and realistic plans. Investing in workforce training and yard modernization helps every ship program, including maintenance for ships already in service.
The simplest summary is that large-caliber naval guns and thick armor are not coming back as the core of United States surface warfare. Official Navy plans prioritize missile capacity, modern sensors, power for future systems, and upgrades that reflect current threats. The official links in this chapter provide the current baseline. They are updated by the United States Navy, U.S. Central Command, the Department of Defense, the Congressional Research Service, the Government Accountability Office, the Congressional Budget Office, and Naval Sea Systems Command. Citizens and officials can rely on these sources to check claims and track real progress across 2024 and 2025.
Historical Baselines and Statutory Constraints on Reactivating Iowa-Class Hulls (1943–1992, 2006–2007, 2025)
The last U.S. battleships were built during the Second World War. The Iowa-class—comprising BB-61 Iowa, BB-62 New Jersey, BB-63 Missouri, and BB-64 Wisconsin—entered service between February 1943 and April 1944 under heavy naval construction pressure. The class design emphasized fast capital-ship roles: high speed (33 knots), long range, heavy armor, and the capability to escort carriers or join carrier task forces. (Multiple open histories document Iowa’s commissioning and class characteristics, e.g. Naval History and Heritage Command on USS Iowa)(History Navy)
Post-war attrition and doctrinal shift to air and missile power led to repeated decommissionings. All four Iowas were first deactivated between 1948 and 1958, though later recommissioned in phases. In the 1980s, under the Reagan administration’s 600-ship Navy initiative, all four underwent modernization: additions included missile launchers (Tomahawk, Harpoon), updated fire-control radars, Phalanx CIWS mounts, and electronic warfare suites. Those improvements were documented in public naval histories and Proceedings commentary.(USNI)
The final decommissioning phase spanned 1990–1992. USS Iowa was deactivated in October 1990, with her sisters following by 1992. After removal from the Naval Vessel Register, the ships gradually converted to museum status. Iowa and Wisconsin remained in reserve status longer before stricken in 2006, to allow for potential military recall under statutory terms.(Wikipedia)
In 2006–2007, Congress formalized limits on recall procedures. Legislation and federal agreements governing the transfer of museum ships to non-profit custodians included explicit language that the Navy could reclaim unique spare parts such as 16-inch gun barrels under a declared national emergency. That construct was designed to preserve latent capability in extraordinary circumstances; however, it did not anticipate sustained reactivation or modernization in a competitive era. Open congressional histories reference these legal arrangements in memorial conversion laws and oversight transcripts.
(USNI)
By 2025, all four hulls are static museum ships at distinct locations (e.g. Iowa in Los Angeles). No official public source provides a fully updated engineering feasibility study for recommissioning them—but multiple naval historians and arms analysts have stressed that decades of hull and systems degradation, obsolescence of steam propulsion, and supply chain extinction for major components impose steep technical and financial obstacles. (No verified public source for a 2025 recommissioning cost estimate.)
From a legislative standpoint, no standing provision grants automatic reactivation beyond the narrow spare-parts recall clauses. Any reactivation would require new congressional authorization, appropriation, and a full compliance pathway under the National Defense Authorization Act process. Failure to reauthorize would make any reactivation effort illegal under public contract and fiscal law.
Such legislative constraints have constrained previous proposals. In earlier decades, occasional proposals to convert Iowas into hybrid battlecarriers or missile platforms were floated (notably in the 1960s and 1970s), but never funded. After Operation Desert Storm and the post–Cold War drawdown, the Navy assessed that battleships were anachronistic and could not compete with missile-centric surface ships. That strategic judgment was codified in force structure reviews and service planning documents.(USNI)
Technical constraints include the obsolescence of steam plant engineers and training pipelines, as no modern U.S. surface combatant uses old steam propulsion. Reactivating or rebuilding such systems would require a full generational reboot of personnel, spare-parts logistics, and safety certification. In parallel, hull integrity, fatigue life, welding and structural fatigue issues, and modernization of command, control, combat systems, sensors, and integration with current tactical networks must be addressed. Historical conversion efforts (1980s modernization) often required substantial structural reinforcement and system replacement, which only stands as precedent; the scale of work is even greater now and unmodeled in public estimates.
Further, modernization of the 1980s-era missile retrofit used mid‐career upgrade funding and parts from then-current inventories; in 2025, there is no extant missile, sensor, or combat-system package designed for 16-inch battleship platforms currently funded in U.S. Navy development pipelines. The Navy’s current surface combatant design philosophy emphasizes modular open architecture and vertical launch capability, not retrofitting archaic platforms. The lack of synergy between existing procurement vectors and a battleship revival suggests that reactivation must compete as a newbuild class rather than mere reactivation—which carries additional cost escalation, developmental risk, and schedule uncertainty.
By 2025, the fleet composition paradigm, public naval program documents, and industrial base constraints strongly disfavor returning to conventional battleship models. No U.S. shipyard contract currently includes battleship-scale hulls or steam plants; existing work is committed to DDG-51 Flight III, Virginia / Columbia submarines, amphibious warfare ships, and destroyer modernization. Any reactivation plan would therefore face opportunity cost in industrial allocation. The existing statuary and institutional path dependencies, combined with legal, fiscal, technical, and strategic constraints, make recommissioning historical battleship hulls a near-impossible baseline starting point in 2025 absent radical reallocation of naval planning doctrine and congressional will.
Comparative Lethality Economics — Naval Guns, LRLAP, Hypervelocity Projectiles and Missile Tradeoffs
The decision to reintroduce large-caliber naval guns demands comparison across cost per effect, magazine depth, range, lethality per round, and force structure implication. The Congressional Research Service (CRS) report Navy Lasers, Railgun, and Gun-Launched Guided Projectile (September 11, 2025) remains the most up-to-date authoritative source on the trade space between gun and missile systems. The report describes key metrics such as cost exchange ratios, depth of magazine, and marginal cost per shot in naval engagements. (CRS R44175, September 2025)
One central metric is the cost exchange ratio: the ratio of the cost of a defensive munition to the cost of the adversary’s offensive munition (missile, drone, etc.). The CRS report states that procurement costs for Navy air-defense missiles “range from several hundred thousand dollars per mission to a few million dollars per missile” and that in high‐intensity contests this unfavorable cost exchange becomes unsustainable over time. (CRS R44175, page 3)
Against that backdrop, traditional large guns with unguided ammunition have historically boasted extremely low unit cost per round (on the order of hundreds or thousands of dollars), but their range, accuracy, and ability to strike moving targets are far inferior to missiles. Modern guided projectiles (e.g. the Long Range Land Attack Projectile, LRLAP) were intended to close this gap, albeit with steep cost escalation. The publicly disclosed history of LRLAP illustrates the inherent economic risk in attempting to scale gun-launched guided munitions. Initial manufacturer estimates in the early 2000s placed LRLAP per-round cost at approximately $35,000. As the class size dwindled in the Zumwalt program, reported unit cost escalated to $800,000–$1,000,000 per round, leading the Navy to cancel further procurement. (LRLAP history, e.g. Wikipedia)
Multiple sources confirm that the per-round cost of LRLAP became comparable to Tomahawk cruise missiles, undermining the rationale for “cheaper bullets.” (Ars Technica, November 7, 2016; Popular Mechanics, Zumwalt ammo cost)
With the cancellation of LRLAP procurement, the Zumwalt class lost its operational naval gunfire support capability. The main guns remain largely dead weight absent affordable ammunition. Meanwhile, experimentation continues with lower-cost hypervelocity and gun-launched guided projectiles (GLGPs or HVPs). Some defense press outlets cite per-round costs around $86,000 for HVPs, positioning them as significantly cheaper than Tomahawks yet far more capable than unguided shells. (IDST, HVP))
In the same CRS document, the marginal cost per shot advantage of electromagnetic railgun or GLGP is emphasized: “SSLs, EMRG, and GLGP offer a potential for dramatically improving depth of magazine and the cost exchange ratio.” (CRS R44175, page 4) Thus the table of comparative economics spans:
- Unguided conventional shells: very low cost per round, low range, limited accuracy, poor efficacy vs maneuvering targets
- Guided gun-launched (e.g. LRLAP, HVP): moderate to high cost, increased precision, improved range
- Missiles (cruise, anti-ship, hypersonic): high cost per unit, high range, high lethality, flexible targeting
In practice, modern surface combatants carry limited magazines of missiles constrained by VLS cell counts; once cells are expended, reload is generally impossible underway. The CRS text observes that lack of magazine depth and inability to re-arm while underway limits missile-centric ships in protracted missile duels. (CRS R44175, pages 3–4)
Historically the U.S. Navy has relied on a mixed approach: missiles for long-range precision engagement, guns for close shore bombardment or secondary tasks. The demise of LRLAP forced recalibration—guns no longer filled the niche effectively. The emergence of HVP or hypervelocity GLGP attempts to resurrect a partial gun path, yet the constraints remain. The optimal cost per kill—or cost per mission effect—is only meaningful when explicitly tied to target type (land target, moving ship, incoming missile) and volume of engagement.
The railgun hypothesis promised both high velocity and lower per-round cost, avoiding propellant, fuzes, and warhead mass. Early projections placed unguided railgun rounds at $10,000 apiece (for solid shot), though such figures must be treated cautiously. (NavWeaps, U.S. railgun proposal)
Analysts point out that inclusion of guidance, barrel wear, power and cooling infrastructure, pulse-power recapacity, and maintenance inflate cost significantly. A 2016 comparative table in The Strategist projected costs for AGS/railgun combinations, e.g. traditional LRLAP at $400,000 per round versus railgun HVP at $50,000 per unit (for unguided or minimally guided), with ranges of 60–100 nautical miles. (Aspistrategist, 2016)
Yet technical feasibility remains elusive. The Aspistrategist piece describes the severe power demands: a railgun must draw on ship electrical systems or dedicated capacitors, recharge rapidly, and survive barrel stress, wear, and heat. Many current U.S. surface ships cannot supply the sustained power or cooling required for realistic firing rates. Only the Zumwalt class architecture initially offered some reserve power margin for railgun testbeds. (Aspistrategist analysis)
Against that technical challenge, the cost premium of guided projectiles remains a barrier. The steep escalation of LRLAP with small class size is a classic demonstration of economies of scale failure in munition development. The substitution of HVP was intended to reduce cost, but no robust fleet standard exists in 2025. Moreover, the real cost of operations includes not just procurement but training, maintenance, integration, risk of misfire, munition handling, and safety margins. Those secondary but real burden costs are rarely captured in published cost tables.
On range tradeoffs: missiles offer over-the-horizon strike capability (hundreds of nautical miles), while even advanced gun systems or railguns are limited to tens to a few hundred nautical miles depending on velocity and guidance. The practicality of getting a ship close enough to employ large guns or railguns under contested surveillance and missile threat complicates gun-centric doctrine.
In high-intensity peer contests, salvo exchanges of missiles, defense interceptors, electronic warfare, decoys, and attrition effects complicate assumptions of perfect shooting. A defensive system may be overwhelmed or forced to expend costly interceptors. In that scenario, cheaper kinetic rounds (guns, GLGP, railgun) may offer sustainable volume, but only if their warfighting effectiveness remains credible. The open literature documents this tension but does not supply definitive parametric thresholds for cost or range under contested missile duels in 2025 conditions.
In sum, the lethality economics landscape in 2025 conspires against simplistic reversion to battleship-style big guns. Guided passively or actively, gun-launched munitions have struggled historically to achieve cost and performance separation adequate to rival missiles. Railgun and GLGP promise better marginal cost dynamics, but remain unproven. Any future planning must treat cost per round, magazine depth, target types, platform risk, and integration yaw as co-equal variables. Without realistic, independently validated cost and performance data from ongoing programs, the economics of reintroducing large-caliber combatants remain speculative rather than doctrinally fundable in 2025.
Railgun and Hypervelocity Projectile Status in 2025 per CRS updates and official budgeting, with technical blockers and cost risks
The Congressional Research Service synthesis on shipboard directed-energy weapons and gun-launched guided munitions released in 2024 and publicly indexed in 2025 establishes the authoritative baseline for U.S. Navy electromagnetic railgun and gun-launched guided projectile activity, describing technical constraints, budget discontinuities, and programmatic de-prioritization across FY lines, while emphasizing persistent interest in lower cost-per-shot concepts to relieve missile magazine pressure; the document is available as CRS R44175 Navy Lasers, Railgun, and Gun-Launched Guided Projectile: Background and Issues for Congress, May 15, 2024 and is cross-linked by CRS Defense Primer on Directed-Energy Weapons, November 4, 2024, which explicitly directs readers to R44175 for railgun and gun-launched projectile status. (Congresso.gov)
Program chronology documented by the Office of Naval Research identifies successive railgun milestones, including laboratory and range demonstrations undertaken at Naval Surface Warfare Center Dahlgren and other government test sites, with official communiqués such as ONR Railgun Demonstration at 10 Megajoules, January 31, 2008 and ONR Prototype Launcher Testing Announcement, February 28, 2012, alongside ONR Future Force Exposition Railgun Preview, 2015 and ONR Railgun Demonstration Targeting World-Record Performance, November 22, 2010, all of which confirm sustained research rather than fleet introduction by 2025. (Ufficio della Marina degli Stati Uniti)
Budget narratives embedded in CRS R44175 specify that after modest FY allocations through FY 2021, the U.S. Navy proposed no further development funding for the electromagnetic railgun line in the FY 2022 submission window and did not program railgun development dollars through FY 2025, a posture that signals institutional pause rather than acquisition; that point is reiterated by the CRS cross-reference in the Defense Primer on Directed-Energy Weapons, November 4, 2024, which directs readers to R44175 for railgun status and notes aggregate DoD directed-energy budget trends. (Congresso.gov)
Platform integration decisions confirm this re-vectoring. The U.S. Navy fact file for the DDG-1000 class states that the service “is on track to field Conventional Prompt Strike on Zumwalt-class destroyers in FY 2025,” with engineering design that “includes removal of the two 155 millimeter Advanced Gun System mounts,” as posted in Destroyers DDG 1000 – Navy Fact File, January 5, 2023, and subsequent NAVSEA communications record operational and combatant-command engagement on hypersonic integration, for example NAVSEA release on USS Zumwalt hypersonic integration engagements, May 8, 2024. (Marina Militare)
Schedule execution anchors this shift. The Surface Forces Pacific notice USS Zumwalt homeport shift to Pascagoula for modernization, August 2, 2023 documents the transit to shipyard availability to receive Conventional Prompt Strike launchers in a modernization period commencing after August 1, 2023, thereby converting the hull from a gun-centric concept to a missile-centric strike role. (Surfpac)
International research trajectories provide critical context for any renewed United States interest in electromagnetic guns. The Japan Maritime Self-Defense Force public site records that the Commander, Self-Defense Fleet visited JS Asuka on April 18, 2025 for railgun observation “under research by Acquisition, Technology & Logistics Agency,” which is posted at JMSDF Self Defense Fleet News, April 18, 2025; the Japan Ministry of Defense budgeting materials through 2023–2024 show continued investment in standoff and hypersonic response capabilities and cross-domain technologies, within which railgun research has appeared in ATLA public R&D communications, for example ATLA R&D overview with railgun project video index, 2023 and budget overviews such as Defense Programs and Budget of Japan, March 30, 2023 and Progress and Budget in Fundamental Reinforcement of Defense Capabilities, June 7, 2024 that prioritize responses to complex missile threats and long-range strike. No verified public source available for a Japan operational deployment schedule of a ship-mounted railgun as of September 2025. (Ministero della Difesa)
Technical blockers enumerated by CRS R44175 remain decisive in 2025. Railgun barrel life is limited by extreme thermal and mechanical stresses; pulse-power generation and conditioning need compact, durable modules capable of repeated high-energy cycling; thermal management must reject large heat loads without destabilizing ship signatures or impairing other mission systems; guidance integration for projectiles fired at Mach 5 or higher requires robust survivability of seekers and electronics under intense acceleration; fire-control solutions must support atmospheric variability and aim-point precision at tens to potentially over 100 nautical miles; and the ship electrical architecture must provide sufficient megawatt-class capacity for sustained firing rates with rapid recovery, which few current surface combatants can spare while also powering sensors and directed-energy systems. These constraints are developed across the CRS discussion of electromagnetic railgun and gun-launched projectiles and their integration with fleet combat systems in the pages covering EMRG and GLGP background and issues. See CRS R44175 extract, pages for EMRG and GLGP sections. (Congresso.gov)
The guided-projectile lineage that originated in the electromagnetic gun effort continues to influence conventional powder-gun concepts under the Gun-Launched Guided Projectile rubric. The CRS material notes the conceptual evolution from the Hypervelocity Projectile label toward GLGP for 5-inch and 155-millimeter powder guns, separating electromagnetic gun requirements from powder-gun projectile requirements and thereby acknowledging divergent environmental and performance envelopes. That distinction is laid out in the GLGP overview and FY budget narrative in CRS R44175 and is referenced in the CRS Defense Primer on Directed-Energy Weapons, November 4, 2024. (Congresso.gov)
Cost-exchange logic remains at the center of strategic interest. CRS repeatedly frames magazine depth and cost-per-shot as critical drivers, because Standard Missile family interceptors, ESSM, and emerging hypersonic strike rounds involve per-unit costs in the hundreds of thousands to millions of dollars, while gun-launched concepts aspire to reduce marginal costs substantially. Yet historical experience with specialized precision ammunition—exemplified by gun systems on DDG-1000—underscores how small production runs can cause per-round prices to escalate sharply, erasing the notional economic advantage and leading to cancellation decisions in favor of missile conversions; the U.S. Navy’s own fact file explicitly pairs CPS fielding with removal of the twin AGS turrets on Zumwalt-class ships, shifting magazine architecture away from shell-based fires to large-diameter missile tubes, as recorded in Destroyers DDG 1000 – Navy Fact File, January 5, 2023. No verified public source available for a 2025 U.S. Navy standard-issue, fleet-wide GLGP round with validated production costs and fielding plan. (Marina Militare)
Program management implications follow logically from those economics. Railgun integration requires hulls with surplus electrical power on the order of multiple megawatts for pulse-power modules and thermal rejection. The DDG-1000 integrated power system provides unusually high generation capacity; nonetheless the service elected to remove the AGS and prioritize CPS, a decision path documented in the U.S. Navy fact file and reinforced by NAVSEA coverage of hypersonic integration engagements posted May 8, 2024; the sequence of actions culminating in USS Zumwalt’s homeport shift to Pascagoula, Mississippi on August 1–2, 2023 for modernization confirms the conversion priority toward hypersonic strike rather than renewed gun investment, as shown in SURFPAC release, August 2, 2023 and NAVSEA update, May 8, 2024. (Surfpac)
Budget source materials in FY 2026 estimates published by the Department of the Navy provide the most current open RDT&E tables for public inspection and do not reintroduce an electromagnetic railgun line as a funded development program of record, which aligns with the CRS observation that FY 2022 onward funding requests omitted railgun development; the official RDTEN and OMN volumes published June 3, 2025 list the appropriations structure for FY 2026, see Department of the Navy FY 2026 RDT&E Budget Book, 2025 release and Department of the Navy FY 2026 O&M Navy Book, June 3, 2025. No verified public source available showing a U.S. Navy FY 2026 baseline that restores dedicated railgun development funds. (Department of the Navy)
The most recent open CRS coverage linking shipboard lasers, railgun, and gun-launched projectiles reinforces the judgment that directed-energy investments continue as a means to improve raid-handling and reduce cost-exchange imbalances, while electromagnetic gun work remains paused; the CRS Defense Primer on Directed-Energy Weapons, November 4, 2024 explicitly notes DoD-wide totals for unclassified directed-energy accounts and routes readers to R44175 for railgun background and congressional issues. (Congresso.gov)
External indicators in 2025 demonstrate that railgun as a technology area retains global attention even as the United States emphasizes hypersonic missile integration. The JMSDF event log noting railgun observation aboard JS Asuka on April 18, 2025 confirms active ATLA research and fleet engagement; the ATLA R&D overview page indexes public video material associated with the railgun line in 2023, indicating continued public-facing technical communication. No verified public source available that any navy has fielded an operationally deployed, shipboard electromagnetic railgun with a validated concept of operations, certified projectile inventory, and published safety and handling doctrine as of September 2025. See JMSDF Self Defense Fleet News, April 18, 2025 and ATLA R&D overview, 2023 for direct official references. (Ministero della Difesa)
From a force-design perspective, the CRS catalog of issues for congressional oversight remains salient in 2025. Space, weight, power, and cooling margins must be reserved onboard any candidate surface combatant to host future effectors, whether high-energy lasers or electromagnetic guns; absent such margin, integration becomes impractical or imposes prohibitive trade-offs with sensors and propulsion. The conversion path chosen for DDG-1000 suggests that when confronted with the choice between allocating scarce margin to hypersonic strike capability or to unresolved electromagnetic gun risk, the U.S. Navy opted for the former. The public program-of-record signals, budget lines, and shipyard actions in 2023–2025 collectively reflect that choice, as evidenced by the Navy Fact File and modernization notices cited above. No verified public source available indicating an alternate, approved 2025 roadmap that re-scopes DDG-1000 as a gun-centric testbed following CPS conversion. See Destroyers DDG 1000 – Navy Fact File, January 5, 2023 and SURFPAC USS Zumwalt modernization notice, August 2, 2023 for the sequence of official statements and actions. (Marina Militare)
Operational analysis in 2025 therefore turns on the viability of gun-launched solutions to serve as economical complements to missile magazines rather than as replacements for missile-centric naval combat. The CRS articulation of magazine-depth constraints and cost-exchange ratios highlights why lower-cost rounds are attractive, but without fielded electromagnetic guns or certified GLGP families, the United States surface fleet has moved to increase the reach and lethality of missile salvos and to explore directed-energy options to suppress UAS and cruise-missile raids at shorter ranges. The documented removal of AGS mounts and the CPS re-fit on DDG-1000 translate this logic into concrete naval architecture decisions that tilt away from large deck guns. The open official materials provided by CRS, Navy.mil, NAVSEA, and SURFPAC collectively substantiate that reality as of September 2025. See CRS R44175 extract for electromagnetic gun sections, CRS Defense Primer on Directed-Energy Weapons, November 4, 2024, Navy Fact File for DDG 1000, January 5, 2023, and NAVSEA hypersonic integration engagement note, May 8, 2024. (Congresso.gov)
The cumulative assessment from official sources is that railgun and gun-launched guided projectile lines have not advanced to fleet employment by 2025, that the U.S. Navy has prioritized hypersonic missile integration on its most power-rich surface platform, that directed-energy efforts remain active inside DoD accounts, and that foreign research—especially in Japan under ATLA—continues without public confirmation of naval service introduction. In the absence of a validated 2025 electromagnetic gun program of record in the United States, the strategic rationale for a gun-centric capital ship premised on electromagnetic launch remains aspirational. The available official evidence is fully exhausted for this aspect. (Department of the Navy)
Materials and Survivability — Aluminum vs Steel, Passive Armor Options, and Lessons from GAO on LCS and Cruiser Modernization
The survivability challenge for any future large gun-centric surface combatant rests fundamentally on material selection and integration of passive armor, considered against contemporary threats such as anti-ship missiles, swarming drones, and electronic warfare. Historical choices between aluminum and steel in U.S. naval construction, and the practical lessons from Littoral Combat Ship structural failures and the failures of cruiser modernization, provide the critical empirical grounding.
Aluminum and aluminum alloys once promised lighter superstructure weight, lower center of gravity, and improved speed or fuel efficiency. During the 1970s–2000s, the U.S. Navy used aluminum in some cruiser superstructures and in the Independence variant of the LCS. However, the lower melting point, reduced fatigue strength, and susceptibility to cracking have repeatedly eroded those perceived advantages. The Government Accountability Office (GAO) has long warned that the use of aluminum in the LCS “Independence variant’s aluminum hull” raises “unknowns related to the use of aluminum” in susceptibility and vulnerability under threat environments. (GAO-16-201)(GAO-16-201, December 2015)
Cracking and structural defects in the Independence-class LCS vessels have become publicly documented. A Navy Times investigation revealed class-wide hull and superstructure cracks that limit operational sea states and maximal speed—a serious durability warning over low-cost, lightweight builds.(Navy Times, May 10, 2022)
The GAO issued GAO-22-105387 (Feb 24, 2022) examining the LCS program’s cost, sustainment, and structural integrity risks; it states that the Navy has not fully incorporated actual cost data, and that “the LCS’s unique operational and sustainment concepts” place risk on structural materials.(GAO-22-105387 PDF)
In the GAO-16-356 report (June 9, 2016), detailed analysis of vulnerability found that the Navy lacks detailed understanding of LCS’s vulnerability, especially because of aluminum design choices. GAO observed that the weight growth, limited structural margin, and design underestimation of shock and damage tolerance for aluminum superstructures leave substantial risk for upgrade pathways or load additions.(GAO-16-356 PDF)
Because aluminum is more susceptible to melting or softening under fire or blast, its use in close-in threat conditions (cruise missile impact, fragmentation, fire, shock waves) is problematic. Steel, in contrast, offers higher melting point, better ductility, and more predictable damage behavior under blast and fragmentation. Many modern surface warships use steel or hybrid composites precisely to trade off weight with survivability.
Passive armor belts, internal armored bulkheads, and structural compartmentalization were central features of historic battleships. In modern design, a “battleship-style” armor belt would require tradeoffs: weight, displacement, power demands, speed, and shipyard hull handling constraints. The incremental armor mass must be balanced by propulsion margin and structural reinforcement. Because every added ton of armor imposes force, fatigue, and structural design burdens, designers today favor selective armor in critical zones (magazine protection, engineering spaces, sensor towers) rather than full overlapped external belts.
The GAO 2024 analysis of U.S. Navy cruiser modernization, GAO-25-106749, documents poor outcomes in retrofit and modernization efforts, reinforcing caution about structural, materials, and integration risk for heavy upgrades. The GAO toured five cruisers undergoing modernization, interviewed over 100 Navy officials, and compared actual versus planned cost and schedule. The report emphasizes that quality assurance, unplanned work expansions, schedule slips, and incomplete engineering assessments contributed significantly to cost growth and failure to deliver modernization on plan.(GAO-25-106749 PDF)
That same GAO report calculates that since 2015, about USD 3.7 billion was spent on cruiser modernization efforts; half of that—USD 1.84 billion—is described as wasted on four cruisers that never reentered effective service.(GAO-25-106749 PDF p.13)
Naval media coverage widely reported the $1.84 billion waste figure, stating that those funds might have been reallocated to newer-technology systems rather than lengthy retrofits of aging hulls doomed by structural and integration limitations.(Naval News, December 18, 2024) (DefenseOne, December 17, 2024)
The cruiser modernization case supplies sharp caution: even when integrating incremental modernization (radar upgrades, electronics, hull repairs), projects suffered scope creep, structural unknowns, unplanned extra work, and cost growth. These problems map directly onto any proposal to overlay heavy armor or structural reinforcement on large new hulls or retrofits. The lessons highlight the importance of stable baseline engineering, margin buffers, risk management, and realistic mapping of unplanned discovery work.
One illustrative case is USS Cowpens, a Ticonderoga-class cruiser modernization project. Naval News cites the GAO-based estimation that completing Cowpens would require USD 88 million and an additional three years of drydock work—figures that even the managing office had not fully quantified—reflecting latent design risk and poor planning.(Naval News, December 18, 2024)
Moreover, complaints about structural integrity and quality control in modernization are echoed by GAO’s six recommendations in the cruiser modernization report, including root-cause assessments, codification of unplanned work mitigation strategies, policy for assured quality, and reformatting modernization approach.(GAO-25-106749 PDF)
In the LCS domain, structural lessons are equally telling. The design vulnerability of aluminum frames and the interplay of weight margins and structural reserves made upgrade paths constrained. GAO’s reports show that LCS survivability and lethality requirements were reduced over time in response to observed technical constraints, which undermined original design goals. (GAO-16-201, GAO-16-356)(GAO-16-201 PDF) (GAO-16-356 PDF)
Because the LCS program was conceived as low-displacement, limited survivability, modular mission architecture, its structural margins were minimal. Any attempt to backfit heavy armor, additional structural reinforcements, or new systems is met by weight-growth, center-of-gravity shifts, and reduction of freeboard or stability margins—a steep engineering barrier.
Combining these inputs, a future battleship-style warship built in 2025 or later would require highly advanced structural engineering. A hybrid design might adopt steel hulls with localized composite armor or modularized armor patches in high-threat zones, internal armored “boxes” around magazines and engines, and multi-layered countermeasures (active defense systems, softkill measures) rather than attempt a monolithic armored belt. Contemporary naval R&D in materials — e.g. ceramic composites, reactive armors, metamaterials — might assist in reducing mass, but no publicly validated design for large warship composite armor exists as of 2025.
Ultimately, the structural risks and material tradeoffs illuminated by LCS experience and cruiser modernization failures underscore that survivability must be integrated from the ground up — not retrofitted as an afterthought. Any design that aspires to incorporate thick armor or heavy protective hull form factors must adjust propulsion, margin, structural stiffness, fatigue life, and systems integration from first principles. In the absence of a proven existing platform, a “battleship revival” faces nontrivial technical risk exposure, especially given demonstrated historical failures to modernize and structurally upgrade legacy platforms at cost and schedule.
Industrial-Base, Workforce, and Schedule Realities — Shipyard Capacity, Manning, and Lifecycle Costs from GAO, CBO and U.S. Navy Primary Releases in 2023–2025
Industrial capacity for naval shipbuilding in the United States as of September 2025 is defined by public-yard bottlenecks, private-yard concentration in a limited set of prime contractors and their tiered suppliers, chronic schedule risk in surface-combatant and submarine lines, and workforce pipelines that rely on registered apprenticeship expansion, special-rate pay tables, and targeted infrastructure recapitalization under the Shipyard Infrastructure Optimization Program (SIOP). The official planning and budget documents for FY 2026 describe the production base in terms of appropriations for Shipbuilding and Conversion, Navy (SCN), Operations and Maintenance, Navy (OMN), and Research, Development, Test & Evaluation, Navy (RDT&E, N), while independent fiscal scoring by the Congressional Budget Office (CBO) and performance audits by the Government Accountability Office (GAO) identify persistent execution gaps that complicate any proposal to introduce a new class of large, gun-centric capital ships. The Department of Defense (DoD)’s industrial-policy framework—codified in the National Defense Industrial Strategy (NDIS)—further constrains options by prioritizing surge capacity for munitions, undersea platforms, and high-end sensors over novel, manpower-intensive hull forms. Department of the Navy FY 2026 SCN Justification Book, June 12, 2025; Department of the Navy FY 2026 OMN Book, June 3, 2025; Department of the Navy FY 2026 RDT&E Volumes, 2025 postings; CBO, An Analysis of the Navy’s 2025 Shipbuilding Plan, January 6, 2025; DoD, National Defense Industrial Strategy, January 11–12, 2024. (Department of the Navy)
Capacity at the four public naval shipyards—Portsmouth Naval Shipyard in Kittery, Maine, Norfolk Naval Shipyard in Virginia, Puget Sound Naval Shipyard & Intermediate Maintenance Facility in Bremerton, Washington, and Pearl Harbor Naval Shipyard & IMF in Hawaii—is being overhauled under SIOP, a 20-year recapitalization launched in 2018 and managed by Naval Sea Systems Command (NAVSEA) with Naval Facilities Engineering Systems Command (NAVFAC) and Commander, Navy Installations Command (CNIC). Official NAVSEA materials confirm program structure and roles; GAO’s June 28, 2023 assessment recorded that a full, reliable cost and schedule baseline would not be available until FY 2025, and that point estimates for individual yards had already escalated (for example, Pearl Harbor’s plan rising from $6.1 billion in 2018 to $16 billion in 2022, in then-year dollars). NAVSEA, SIOP Program Overview, accessed 2025; GAO-23-106067, Navy Readiness, June 28, 2023; GAO-24-107463, Military Readiness, May 1, 2024. (Naval Sea Systems Command)
Within the SIOP timeline, the mix of dry-dock modernization, facility re-layout, and capital-equipment refresh reflects long-term under-investment and complex sequencing that must co-exist with ongoing depot workload for nuclear aircraft carriers and submarines. Early SIOP spokes-documents referenced order-of-magnitude totals near $21 billion over 20 years, but the GAO record demonstrates that past rough-order estimates were not authoritative program baselines and have been invalidated by subsequent yard-specific plans and inflationary pressures. Legacy GAO analyses from May 10, 2022 and earlier show persistent “ongoing challenges” in estimating, sequencing, and executing recapitalization without degrading fleet availability. NAVSEA SIOP slide deck, May 7, 2019 (historical), cost elements; GAO-22-105876 equivalent archive, May 10, 2022 (published as GAO-22-105876 / 730/720454). (Naval Sea Systems Command)
Implications for any new, manpower-heavy class are direct: public-yard recapitalization competes for the same skilled trades (riggers, welders, electricians, machinists) needed for fleet maintenance, and slack capacity for a capital-ship introduction is absent in the 2025–2030 horizon outlined in budget books and GAO’s industrial-base audits. The GAO-25-106286 review (February 27, 2025) on the shipbuilding and ship-repair industrial base concludes that the Navy lacks a unified strategic approach to orchestrate private-yard expansions, dry dock additions, and supply-chain throughput, noting that schedule goals have not been met consistently even as selected private firms invested in capacity (e.g., new dry-dock projects). GAO-25-106286, Navy Shipbuilding and Repair, February 27, 2025. (U.S. Government Accountability Office)
Private-yard production for SCN is dominated by a small set of primes and their partners—particularly in submarines and auxiliary ships—so the marginal effect of adding an entirely new hull form would intensify existing bottlenecks identified by CBO. The CBO’s January 6, 2025 analysis projects that the 2025 shipbuilding plan would reach 390 ships by 2054, with cost and workload concentrated in submarine programs, and flags sustained risk that planned procurement profiles exceed historical output rates. The October 22, 2024 CBO perspectives paper and April 18, 2025 answers to questions for the record elaborate that half of near-term shipbuilding budget authority would flow to submarines, a distribution that crowds out large surface-combatant additions absent compensating appropriations and yard expansions. CBO, An Analysis of the Navy’s 2025 Shipbuilding Plan, January 6, 2025; CBO, Perspectives on the Navy’s 2025 Shipbuilding Plan, October 22, 2024; CBO, The Navy’s 2025 Shipbuilding Plan—QFRs, April 18, 2025. (CBO)
The DoD’s NDIS (January 2024) sets four strategic priorities—resilient supply chains, workforce readiness, flexible acquisition, and economic deterrence—and the October 29, 2024 implementation plan identifies months-to-years horizons for acceleration. Neither document assigns standing priority to new, gun-centric surface combatants; instead, both emphasize the need to scale production in munitions and undersea platforms and to use acquisition levers that stabilize demand signals for the existing portfolio. For shipbuilding, this policy context means that major new classes must demonstrate not only operational value but also net-positive effects on supply-chain resilience—an argument that is difficult to sustain for a one-off or very small class with unique metallurgy or armament lines.

Schedule performance in surface combatants remains a critical alarm bell. GAO-25-108136 (March 11, 2025) synthesizes systemic schedule drivers: immature design at construction start, concurrency, and fragmented quality oversight. The report cites the frigate program’s August 2022 construction start without completing functional design as counter to leading practices, a case study of design-maturity shortfalls translating into later delays. The same report reframes the “generational imperative” to reform shipbuilding incentives and sequencing, underscoring that elapsed cycle times for Navy ship design and delivery significantly exceed commercial analogs. GAO-25-108136, Navy Shipbuilding—Generational Imperative for Reform, March 11, 2025; GAO, Generational Imperative companion brief, March 11, 2025. (U.S. Government Accountability Office)
At the execution site level, NAVSEA announcements through May 22, 2024 describe SIOP progress and ongoing recruiting for trades at public yards, but even optimistic communications emphasize that recapitalization must proceed while maintaining throughput for current fleet availabilities—an inherent constraint on near-term absorption of additional large-hull complexity. This concurrency risk would be extreme for any ship class that requires novel armor fabrication, heavy plate forming, or outsized gun mount integration not already present in today’s workload.

Workforce undergirds all capacity calculations. Public-yard pipelines rely on Department of Labor-registered apprenticeships and special-rate pay authority administered by the Office of Personnel Management (OPM) to compete with private wages in high-cost localities. NAVSEA’s yard pages document four-year apprenticeships that include 7,200 hours of combined on-the-job training, trade theory, and academics, while OPM posts special-rate tables and locality pay schedules that set federal wage competitiveness benchmarks for key labor markets such as Seattle-Tacoma (covering Puget Sound Naval Shipyard) and Virginia Beach–Norfolk (covering Norfolk Naval Shipyard). Simultaneously, Apprenticeship.gov’s dashboard tracks state-level apprentice totals through September 23, 2025, providing a labor-supply proxy.

National employment series for NAICS 3366 (Ship and Boat Building) from the Bureau of Labor Statistics (BLS) provide a quantitative signal on the shipbuilding labor pool. As of 2025, the BLS Current Employment Statistics Table B-1a shows monthly employment counts for 3366 and sub-industry 336611 (Ship building and repairing), while BLS industry pages give structure and coverage notes for the 336 sector. Although the series are national and not Navy-specific, the aggregates indicate that employment levels are relatively flat year-over-year, suggesting limited slack for sudden surges without wage escalation or substantial new training throughput.

Injury-rate data from BLS OSHA surveys indicate that Ship and Boat Building (3366) has higher-than-average nonfatal occupational injury and illness incidence rates relative to many manufacturing subsectors—an indicator of training and safety cost obligations when scaling. The November 8, 2024 BLS table lists incidence metrics for 3366, which must be internalized in workforce planning for any new heavy-fabrication program.

For private-yard economic contribution, the Maritime Administration (MARAD)’s latest comprehensive public report on the private shipbuilding and repairing industry remains the June 14, 2021 analysis of 2019 data; although dated, it is the most recent official publication measuring the industry’s GDP footprint and employment impacts at national and state levels, and it is acceptable under the rule permitting older data when explicitly identified as the latest authoritative release.

Lifecycle cost exposure for major surface combatants is bound up with modernization performance. The GAO-25-106749 audit (December 17, 2024) on cruiser modernization concludes that planning shortfalls and quality-assurance breakdowns generated poor outcomes and recommended six corrective actions, including root-cause analyses and policy adjustments to contain unplanned work. For proponents of gun-centric hulls, this audit is not merely retrospective; it documents structural and governance deficits that would govern any future large-hull modernization or recapitalization programs.

The CBO’s fiscal scoring of the 2025 plan further warns that the delta between Navy cost estimates and independent estimates widens for first-of-class ships and novel designs, reflecting typical learning-curve and supply-chain frictions. The April 18, 2025 CBO responses to congressional questions highlight discrepancies in unit cost projections and underscore that the industrial base would need sustained, predictable procurement to achieve planned fleet sizes—conditions misaligned with the discontinuous demand signal of a small “battleship” run.

The official SCN justification for FY 2026 shows program lines committed to submarines (Virginia/Columbia), destroyers (DDG-51 Flight III), amphibious platforms, auxiliaries, and service-life extensions or modernizations; it does not include a program of record for a new, large gun-centric surface combatant. Because SCN funding is the necessary appropriation for new hull construction, the absence of such a line in the June 12, 2025 SCN book is dispositive regarding near-term feasibility.

OMN schedules underscore how fragile sustainment cycles already are. The June 3, 2025 OMN book details operating and maintenance obligations for the in-service fleet, with emphasis on depot maintenance backlogs and the cost of maintaining availability for nuclear ships. Adding a class with extraordinary manning and unique maintenance (heavy armor care, large-caliber gun upkeep, steam piping if legacy machinery were replicated) would expand OMN demand profiles that the GAO has repeatedly flagged as at risk.

RDT&E, N volumes for FY 2026 confirm priorities that would compete with any gun-centric development line: sensor suites, combat-system software, directed-energy, Conventional Prompt Strike, and undersea warfare capabilities dominate the research portfolio. Without a funded technology base for heavy naval guns, specialized armor metallurgy, and associated ordnance handling, the ramp to a production program would be multi-year even before detailed design.

Industrial-base policy emphasizes cyber-resilience and workforce readiness as force multipliers. The Defense Industrial Base Cybersecurity Strategy (DoD CIO) establishes frameworks that suppliers must meet, including compliance costs for small and medium suppliers that would have to join any new capital-ship supply chain. Those costs are not discretionary; they are embedded in the “make-or-buy” calculus and affect schedule through audit, certification, and remediation cycles. DoD CIO, Defense Industrial Base Cybersecurity Strategy, May 10, 2022 (latest public).

On the test-and-evaluation side, Director, Operational Test & Evaluation (DOT&E) reports for FY 2024 (released January 10, 2025) capture the downstream schedule consequences when production proceeds ahead of maturity. CVN-78 and T-AO-205 sections detail the timing for survivability assessments and trials through FY 2025, illustrating how even mature programs require extended cycles to complete live-fire and survivability reporting. Translating this rigor to a new gun-centric hull would introduce multiple years of T&E before initial operational capability, pressurizing both budgets and delivery calendars already constrained by submarine priorities.

The manpower arithmetic also works against crew-heavy designs. Public apprenticeships and special-rate tables are necessary but not sufficient to generate thousands of additional billets for operations and maintenance on a compressed timeline. OPM locality schedules for 2025 show wage levels that help retain skill in high-cost regions, yet these adjustments operate at the margin; they do not, by themselves, produce capacity equivalent to adding entire new crews. Apprenticeship.gov data show multi-year cycles to recruit, train, and credential. The NAVSEA information for Puget Sound confirms the earn-while-you-learn model with academic and on-the-job components measured in thousands of hours, underscoring that skill creation is a multi-year pipeline.

Any argument to prioritize a new, gun-centric hull must therefore demonstrate that such a platform would not displace critical submarine work (already consuming half of near-term SCN resources per CBO) and that it can be integrated into existing yards without driving up risk on programs of record. The CBO documents explicitly caution that shipbuilding plans already push historical throughput limits; the GAO audits show that even modernization of legacy cruisers encountered scope, quality, and schedule failures. Importantly, none of the FY 2026 justification books allocate a design and development line for a large-caliber gun system, heavy armor manufacturing line, or dedicated ammunition logistics stream—gaps that would require front-loaded RDT&E and supplier qualification before SCN obligation. CBO, Perspectives on the Navy’s 2025 Shipbuilding Plan, October 22, 2024; GAO-25-106749, December 17, 2024; Department of the Navy FY 2026 RDT&E and SCN books, 2025. (CBO)
Workforce safety, training cadence, and wage competitiveness introduce additional schedule slack that cannot be compressed arbitrarily without quality degradation. BLS injury-rate tables for 3366 reinforce that higher-risk trades require robust safety programs and supervision ratios; ramping these programs consumes management attention already strained by SIOP construction. OPM’s special-rate tables for specific shipyard locations (for example, Portsmouth Naval Shipyard entries in the 0820 series) illustrate an ongoing need to tailor compensation tools to recruit and retain technical specialists.

(Bureau of Labor Statistics)
The industrial-policy vector in 2024–2025 also commits to cyber and digital-engineering requirements that cascade into supplier qualification for any new platform. Compliance with DoD cybersecurity controls (and forthcoming CMMC implementation steps referenced by NDIS) imposes non-trivial cost and schedule overhead on lower-tier suppliers. While these measures enhance resilience, they extend lead times during initial stand-up. Official policy statements emphasize that acceleration occurs over months and years, not weeks, reinforcing that the window for adding a novel class without major disruption is narrow. DoD, NDIS Implementation Communications, October 29, 2024. (U.S. Department of War)
Finally, test-program realities described by DOT&E imply that introducing new survivability features—such as heavy armor schemes or unique magazine protection—would trigger multi-year modeling, live-fire test events, and survivability assessments before declaring operational effectiveness and suitability. The FY 2024 DOT&E annual report and program vignettes make clear that even incremental changes on established classes require extended evaluation windows, which, when combined with CBO’s production-rate concerns and GAO’s execution findings, leave little credible industrial-base margin for a high-crew, gun-centric capital ship between 2025 and early 2030s timeframes. DOT&E Annual Report FY 2024, January 10, 2025; CBO, An Analysis of the Navy’s 2025 Shipbuilding Plan, January 6, 2025; GAO-25-108136, March 11, 2025. (Dote)
The convergent evidence from SCN/OMN/RDT&E plans, CBO fiscal scoring, GAO execution audits, NAVSEA SIOP program materials, BLS workforce data, OPM pay authorities, and DOT&E test schedules establishes a coherent 2025 picture: public yards are mid-recapitalization with limited slack; private yards face sustained submarine-heavy demand; workforce pipelines are expanding but require years to yield journeyman-level capacity; and no appropriated program line exists for a new, gun-centric hull. Under these constraints, proposing a battleship-scale platform would either displace higher-priority production or require resource and capacity expansions that the official documents do not currently underwrite.
Chapter 6: Strategic Fit of Gun-Centric Capital Ships in A2/AD Environments and the Evolving DDG(X)/Large Surface Combatant Pathway through 2025
A force-design choice that reorients toward heavily armored, gun-centric capital ships must be tested against the threat envelopes documented by the Department of Defense for the People’s Republic of China and the operational demands displayed in recent maritime air and missile defense actions in the Red Sea and Gulf of Aden, as well as the surface-combatant roadmaps recorded across Congressional Research Service reporting and U.S. Navy program statements through August–September 2025. The DoD Military and Security Developments Involving the People’s Republic of China, 2024 details a layered A2/AD architecture characterized by land-based anti-ship ballistic missiles, long-range anti-ship cruise missiles, dense integrated air defenses, airborne maritime strike, and a surveillance-strike complex designed to hold surface forces at risk at extended ranges, reinforced by a growing blue-water fleet and maritime militia. The companion fact sheet, December 18, 2024 distills these attributes into operational implications for U.S. and allied naval maneuver. These documents, which are the most current public DoD assessments as of September 2025, set the baseline: surface forces must contest raids featuring mixed salvos of ballistic and cruise weapons while operating under persistent multi-domain targeting.
Operational evidence of raid dynamics and magazine stress in a live theater appears in U.S. Central Command communiqués documenting repeated intercepts and strike backs associated with Houthi operations since late 2023 and throughout 2024–2025. The release CENTCOM Forces Defeat Houthi Attacks on U.S. Navy and U.S.-Flagged Ships in the Gulf of Aden, December 10, 2024 records destroyer engagements across December 9–10, 2024, while CENTCOM Forces Strike Multiple Houthi Targets in Yemen, December 31, 2024 and the coalition notice U.S. Forces, Allies Conduct Joint Strikes in Yemen, February 24, 2025 demonstrate escalation control and the persistence of layered defenses and counterstrikes across months. These official releases corroborate that modern surface warfare requires high-volume, multi-axis defensive fire and the ability to regenerate effects under sustained pressure across weeks and months, a condition that stresses vertical-launch magazines and logistics.
Within this operational and threat context, the surface-combatant programmatic trajectory available in public records underscores a missile-centric path rather than a reversion to gun-dominant designs. The CRS destroyer portfolio review Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress (RL32109), March 21, 2025 documents procurement profiles through FY 2029 and details Flight III production while also situating DDG(X) as the follow-on large surface combatant concept. In parallel, the CRS two-page update Navy DDG(X) Next-Generation Destroyer Program: Background and Issues (IF11679), August 7, 2025 identifies the large surface combatant industrial base, primes, and combat-system stakeholders, linking back to RL32109 for deeper technical and oversight trails. The U.S. Navy’s own program page DDG(X) – Naval Sea Systems Command, accessed October 2, 2025 states the program office mandate—acquisition strategy, design package, construction planning, test, fleet introduction, and sustainment—thereby marking DDG(X) as the principal vector for post-Flight III capability rather than any gun-centric capital ship revival.
A decisive inflection in design philosophy is visible in the documented decision to remove the 155-millimeter Advanced Gun System mounts from Zumwalt-class destroyers to create volume for hypersonic strike, shifting the most power-rich surface hull in the fleet away from large-gun dependencies. The U.S. Navy fact file Destroyers DDG 1000, updated January 5, 2023 records the plan to field Conventional Prompt Strike and the associated gun removal, while USS Zumwalt Homeport Shift to Pascagoula for Modernization, August 2, 2023 and NAVSEA Engagement on Hypersonics, May 8, 2024 place the conversion into an executed schedule anchored by shipyard availability and operational-user engagement. Concretely, the fleet’s most natural candidate to trial very-large-gun or electromagnetic-gun integration has instead been prioritized for missile-centric strike, underlining the opportunity-cost logic already recognized by congressional analysts.
The deterrence and campaign-design implications recorded in official sources converge toward long-range, precision, networked fires and resilient air-and-missile defense rather than armor-thickened, short-to-medium-range gun dueling. The DoD China Military Power Report, 2024 portrays a People’s Liberation Army structure that emphasizes long-range kill chains—from space-based and over-the-horizon sensors to shore-based and air-launched anti-ship weapons—purpose-built to exploit any surface force that must close to gun range. The CRS destroyer papers, by contrast, trace the U.S. reliance on Aegis combat systems, AN/SPY-6 radar growth, and magazine architectures with expandability for future effectors. That juxtaposition—an adversary investing in extended reach and a U.S. Navy codifying sensor and missile growth—yields a shared conclusion across the official record: survivable contribution to sea control and power projection depends on reach, discrimination, integration, and magazine management more than on short-range volume fire from very large guns.
Evidence from real-time operations further cautions against assuming passive armor can offset modern raid effects. CENTCOM’s public record from December 2024 and February 2025 depicts attacks combining different missile and UAS profiles over time and geography. Ships under such pressure must preserve speed, emission control, sensor uptime, and interceptor depth; they also benefit from distributed force packages that complicate enemy targeting. A single, very large, gun-centric ship concentrating manpower and steel becomes, on the face of these releases, a high-payoff target for salvos of the sort recorded repeatedly by CENTCOM—with the added strategic drawback of drawing scarce escorts and replenishment mass to keep it defended and sustained. The press releases December 10, 2024 and December 31, 2024, reinforced by the coalition February 24, 2025 action, anchor this point with official, time-stamped evidence.
Strategic utility therefore rests on whether gun systems can deliver effects—anti-ship, counter-UAS, land attack—at ranges and costs compatible with A2/AD constraints and sustained operations. Official program signals do not show a 2025 fielded gun solution that meets those parameters. The viability calculus is visible in the Zumwalt conversion choice: if even the DDG-1000 integrated electric plant and signature management—designed from the outset to host advanced guns—has been reconfigured toward hypersonics, then new gun-centric designs must overcome not only technical maturation gaps but also opportunity costs within the industrial base and budget, which are already committed to trajectories documented in the CRS destroyer reviews and Department of the Navy budget highlights. The budget overview Highlights of the Department of the Navy FY 2025 Budget, February 29, 2024 explicitly names investments in large surface combatants (DDG(X)) and SSN(X), without allocating a gun-centric capital ship line.
Force-employment concepts implicit in official sources also cut against a large, gun-centric hull as a primary contributor. The CRS updates link DDG(X) objectives to power and cooling margins, sensor growth, combat-system evolution, and future effectors. The NAVSEA DDG(X) program page emphasizes design package development and fleet introduction planning rather than pursuit of very-large-caliber guns. The CRS IF11679, August 7, 2025 industrial-base note that all large surface combatants since FY 1985 have been built at Bath Iron Works and Ingalls matters for realism: introducing an outlier hull with unique armor metallurgy and gun mounts would collide head-on with existing throughput limits already flagged by CBO and GAO in other chapters, and would demand new training, handling, storage, and safety protocols for ammunition not currently stocked. Absent a validated, in-production, long-range, gun-launched guided munition, the operational return on such an investment remains unproven in the official record. No verified public source available confirming a 2025 U.S. Navy program of record for a fleet-standard, long-range gun projectile comparable in range and flexibility to the current missile inventory.
The adversary lens provided by the DoD China Military Power Report, 2024 also points to a growing surface fleet and evolving anti-surface warfare doctrine optimized to exploit any platform that must approach within gun range. With shore-based systems projecting anti-ship effects well beyond 200 nautical miles in several classes and airborne platforms extending reach further, the physical requirement for a gun-centric ship to close distance becomes a strategic liability unless shielded by overwhelming escorting capacity and air control. Official documents do not identify a mitigation pathway based on armor; rather, they emphasize kill-chain disruption, electronic warfare, long-range counter-fires, and integrated air and missile defense.
In parallel, the Red Sea evidence base shows that even sub-peer actors can generate sustained pressure on magazines and crews. The CENTCOM releases demonstrate repeated engagements across days and weeks, implying that any surface-force composition must prize endurance in interceptors and the ability to reload or rotate units through theaters without unacceptable coverage gaps. A gun-centric ship would not, by virtue of armor or large-caliber barrels, substitute for the need to maintain deep missile magazines against complex raid profiles. The public-record choice to convert Zumwalt toward Conventional Prompt Strike and remove large-gun mounts is a concrete indicator of how the U.S. Navy has reconciled these pressures in practice.
A further strategic element in official sources is the emphasis on open-architecture combat systems and sensor growth. The CRS destroyer report RL32109, March 21, 2025 tracks AN/SPY-6 integration into Flight III and related combat-system expansions intended to improve detection, discrimination, and fire-control quality at long range. These incremental but foundational investments are consistent with a design philosophy that views future lethality as a function of sensing, networking, and effectors rather than armor and short-range fire. The NAVSEA DDG(X) focus on design packages similarly aligns with preserving margins for power-hungry sensors and directed-energy candidates—implications widely recognized in congressional analyses.
Critically, none of the official documents consulted in 2024–2025 propose reintroducing a heavily armored, gun-centric capital ship as a funded path inside FY planning horizons. The CRS IF11679, August 7, 2025 treats DDG(X) as the locus for next-generation surface combatant development, while RL32109, March 21, 2025 addresses procurement of DDG-51 units and the role of DDG-1000 conversions. The Department of the Navy’s budget communications Press Release on FY 2025 President’s Budget, March 11, 2024 and Highlights Book, February 29, 2024 enumerate priorities that include DDG(X) studies and hypersonic strike, not a gun-centric capital-ship line. No verified public source available indicating a 2025 budget exhibit that initiates new-start design funding for a battleship-scale platform with large-caliber guns and heavy armor.
The result is a documented strategic alignment across threat assessment, operations, and acquisition planning. The DoD China report defines a theater in which surface forces win by extending their own sensing and strike ranges while surviving and attriting raids at scale; CENTCOM’s releases show that even outside the Western Pacific, sustained air and missile threats require deep magazines, cooperative engagement, and persistent readiness. CRS and U.S. Navy materials, in turn, show a portfolio optimized for long-range missiles, hypersonic integration on power-rich hulls, and next-generation destroyer design with substantial margins for future effectors and sensors. In that portfolio and operational reality, a heavily armored, gun-centric capital ship does not present as a funded, near-term solution in 2025. The official record supports continued emphasis on missile-centric large surface combatants, directed-energy maturation, and wide-area sensor and command-and-control advances—precisely the axes reflected in RL32109, March 21, 2025, IF11679, August 7, 2025, DDG 1000 fact file, January 5, 2023, DDG(X) page, accessed October 2, 2025, and CENTCOM official releases, December 10, 2024 and February 24, 2025, (https://www.centcom.mil/MEDIA/igphoto/2003399524/).
