The U.S. Navy's Fiscal Year 2027 Shipbuilding Plan is offering the clearest picture yet of the Trump administration's new battleship program, revealing a nuclear-powered surface combatant designed around hypersonic weapons, massive electrical generation capacity, and future directed-energy systems. Identified as BBGN — short for guided missile nuclear battleship — the program calls for procuring three ships across the FY2027-FY2031 defense plan.
The shipbuilding plan confirms several details that had previously only been hinted at publicly by Navy officials and the Trump administration. Most notably, the report explicitly identifies the vessel as nuclear-powered. According to the document, the future battleship is intended to deliver "high-volume, long-range offensive fires" while serving as a survivable forward command-and-control platform for distributed naval warfare. The Navy says the ship would feature vastly expanded power generation, advanced payload modules for hypersonic weapons, large missile magazines, electronic warfare systems, high-energy lasers, and advanced naval guns.
Previously released Navy concept art offered additional clues about the battleship's intended role and capabilities. One official rendering depicts a stealthy, heavily armed surface combatant equipped with 128 Mk41 vertical launch cells, 12 Conventional Prompt Strike hypersonic missiles, dual 300-kilowatt laser weapons, SPY-6 radar arrays, advanced electronic warfare systems, and even a 32-megajoule railgun firing hypervelocity projectiles. The rendering also shows a large command-and-control suite capable of embarking a fleet commander, along with a flight deck and hangar sized for V-22 Ospreys and future vertical lift aircraft.
Unlike the Arleigh Burke-class destroyer fleet, which the Navy says has reached the limits of its growth capacity, the battleship is being designed with significant future growth margins for power generation, weapons, and computing demands. The Navy also says the ship will use modular construction and distributed manufacturing techniques modeled partly on commercial shipbuilding practices and foreign shipyard production methods. The concept builds on earlier comments from Navy and administration officials dating back to late 2025, when President Donald Trump first announced the battleship initiative as part of his broader "Golden Fleet" naval buildup plan.
The Navy's newest Shipbuilding Plan lays out a sweeping 30-year roadmap to expand the fleet, including a massive $65.8 billion shipbuilding request for FY2027 alone. The plan calls for 34 manned ships and 5 unmanned platforms next year, while the broader five-year defense plan seeks 122 manned vessels and 63 unmanned systems. The Navy says the effort is aimed at reversing decades of stagnation as the fleet remains stuck at 291 battle force ships — well below the statutory requirement of 355.
Key Takeaways:
1. U.S. Navy will procure three nuclear-powered BBGN-class battleships under the FY2027-2031 defense plan.
2. Lead ship named USS Defiant will feature 128 Mk41 vertical launch cells, 12 Conventional Prompt Strike hypersonic missiles, and dual 300-kilowatt laser weapons.
3. Unlike Arleigh Burke-class destroyers, the ship is designed with significant growth margins for future power demands, weapons systems, and computing requirements.
4. Pentagon's FY2027 shipbuilding budget totals $65.8 billion covering 34 manned ships and 5 unmanned platforms.
5. Navy fleet currently stands at 291 battle force ships below statutory requirement while program aims to close this gap.
