Proposed Navy Battleship Fleet Could Cost $275 Billion and Strain Shipyards
A proposed fleet of 15 nuclear-powered Navy battleships could cost approximately $275 billion while demanding substantially more output from U.S. shipyards already contending with delayed programs. The price and the production challenge are inseparable: this would be a new class of 35,000-ton surface combatants entering an industrial base that must continue building destroyers, aircraft carriers and submarines.
The Congressional Budget Office assessment released August 5 estimates the first ship at $23.4 billion, roughly $6 billion above the Navy’s initial December 2025 estimate. Each of the following 14 ships would cost approximately $18 billion, bringing the proposed program to about $275 billion in 2026 dollars over the 2027-2056 period. These are estimates based on a prospective design and acquisition plan, not approved construction costs.
The lead ship alone would be considerably more expensive than the approximately $13.3 billion construction cost cited for the USS Gerald R. Ford aircraft carrier. That comparison does not make the two platforms equivalent, but it places the battleship’s projected cost in the top tier of naval procurement. It also shows why the program cannot be treated as simply another addition to the Navy’s surface fleet.
Shipyard throughput is the harder constraint
The Navy’s schedule calls for approximately one battleship every other year while production continues at two Arleigh Burke-class destroyers annually. Under the 2027 shipbuilding plan, annual funding required for surface combatants would rise from about $11 billion to $19 billion compared with the 2025 plan. By 2035, shipbuilders would need to produce 12% more total tonnage, while the required output of large surface combatants would more than double. Across the longer plan, large-combatant tonnage would rise 60%.
That increase is not merely a request for more steel. The proposed ship combines nuclear propulsion, unprecedented surface-combatant size and advanced systems in a new design. At 35,000 tons, it would be more than three and a half times the size of an Arleigh Burke-class destroyer and more than twice the size of a Zumwalt-class destroyer. CBO concluded that, if built to the stated specifications, it would be the world’s largest surface combatant and the Navy’s largest since World War II.
The available yards also have different capabilities. Bath Iron Works and Ingalls Shipbuilding have built the Navy’s large surface combatants for decades, but they are not certified to construct nuclear-powered ships. The reported concept would distribute module work among multiple yards and conduct final assembly at HII’s Newport News Shipbuilding, which already builds nuclear-powered aircraft carriers and submarines. Adding another large nuclear program there could force schedule and workforce tradeoffs across existing Navy orders.
Those tradeoffs matter because capacity cannot be measured solely by dry-dock space. A Government Accountability Office assessment documented Navy ships delivered as much as three years late, disappointing performance and resource disruption linked to unrealistic cost and schedule assumptions. Shelby S. Oakley, a GAO director, described the resulting pressure as operating in “a perpetual state of triage.” A new lead ship would add design maturation, supplier coordination and first-of-class production demands to that environment.
The $275 billion estimate still has major boundaries
The battleship remains a proposal, and its publicly described specifications are not a final design. CBO acknowledged that its estimate could move higher or lower as displacement, configuration, construction methods and the division of work among shipyards become clearer. The 2028 start and the planned cadence through 2056 are assumptions used for estimating the program, not guarantees that contracts and deliveries will proceed on that schedule.
Nuclear propulsion illustrates the cost boundary. It raises construction complexity and limits where final assembly can occur, but it could eliminate conventional fuel purchases and reduce some operating costs over the ships’ lives. CBO did not quantify those potential lifetime savings, so they cannot presently be used to offset the $275 billion procurement estimate. Taxpayers and Navy planners therefore have a detailed acquisition-cost projection without a complete lifecycle comparison.
The central choice is not simply whether a very large combatant can be designed. It is whether the Navy can fund and build 15 of them without worsening delays elsewhere or displacing other fleet requirements. Before the first planned order in 2028, the program will need firmer specifications, a credible division of shipyard work and evidence that the required production increase can coexist with the Navy’s current nuclear and surface-ship workload.
