CBO: Lead Trump-Class Battleship Could Cost $23.4 Billion
The 35,000-ton USS Defiant would gain unlimited range and power for advanced weapons, but the program faces supply-chain and manpower shortages, officials said.
- On August 4, 2026, the Navy confirmed the future Trump-class battleship USS Defiant will be nuclear-powered, marking the United States' first nuclear-powered surface combatant since the Cold War Period.
- Nuclear power was selected over conventional propulsion to provide the endurance and energy density required for high-output lasers, enabling the ship to operate across the Pacific.
- The planned 15-ship fleet carries an estimated cost of roughly $217.6 billion, featuring 128 vertical-launch cells and 12 weapon positions, though final armor specifications and combat-system baselines remain unpublished.
- Construction relies on BWX Technologies, the only facility capable of producing necessary nuclear reactors, raising concerns the program will worsen delays on Ford-class carriers and AUKUS reactor work.
- Congress has not yet approved the $1 billion in advance procurement for fiscal 2027, and House and Senate negotiators had not reconciled stopgap bills as of August 4, 2026.
