Navy 30-Year Shipbuilding Plan Includes Nuclear-Powered Battleship and Overseas Auxiliary Construction

The Navy's 30-year shipbuilding plan, published May 11, states the Trump-class battleship will be nuclear-powered; Navy officials had previously described gas turbine and diesel propulsion for the ship, Inside Defense reported. The plan projects 15 BBG(X) hulls over 30 years and describes the ship as a dedicated long-range fires and command platform, not a destroyer replacement; USNI News reported a potential per-unit cost of $17.5 billion. The service is also seeking congressional authorization to build auxiliary ships at foreign shipyards, according to Breaking Defense. The plan cites an ongoing review of the CVN-82 Ford-class design aimed at improving lethality and reducing cost.

Analysis
Nuclear propulsion concentrates BBG(X) construction risk at Newport News, the only U.S. nuclear surface-ship yard and one already managing carrier and submarine backlogs. Per the official plan and specialist outlets, the program's $17.5 billion per-hull cost would exceed that of a Ford-class carrier. Stacking 15 hulls against simultaneous destroyer and submarine commitments from FY30 frames a fiscal competition Congress has yet to endorse. The overseas auxiliary authorization request confirms domestic yard capacity as a present constraint. The nuclear propulsion declaration may instead be aspirational requirements-setting ahead of formal design definition, with reversion to conventional propulsion feasible under congressional pressure. The BBG(X) is unlikely to receive initial R&D funding by the close of FY27, with no appropriations language committing development funds.
