A Congressional Budget Office report estimates the first Trump-class nuclear-powered guided missile battleship (BBG(X)) will cost $23.4 billion, with the full 30-year fleet projected at $275 billion. The report details advanced armaments including hypersonic missiles, railguns, and laser systems. The Trump administration announced plans for the new class in December 2025.
The Congressional Budget Office (CBO) has issued a detailed cost estimate for the proposed Trump-class nuclear-powered guided missile battleship (BBG(X)), projecting a fleet cost of $275 billion over 30 years and a first-ship price tag of $23.4 billion, making it the most expensive warship ever built for the US Navy. The report, cited by the source specializing in Middle Eastern affairs, describes the 35,000-ton vessel as the most heavily armed battleship ever constructed, equipped with surface-to-air missiles, land-attack missiles, anti-ship missiles, hypersonic missiles, nuclear-capable cruise missiles, advanced laser systems, and railguns.
The Zioneer previously reported on August 5 that the CBO had estimated the fleet at $275 billion, with the first ship costing roughly $23 billion, citing a Bloomberg correspondent. The new report provides additional technical specifications and confirms the administration's December 2025 announcement of intent to develop the class.
The Trump administration's push for a new generation of nuclear-powered surface combatants represents a significant shift in US naval strategy, emphasizing large, heavily armed surface vessels capable of sustained operations. The CBO's cost estimate will inform congressional budget deliberations as the program moves toward potential authorization.
