Costs and capacity challenges
The U.S. Navy’s proposed nuclear-powered battleship fleet is expected to cost approximately $275 billion in 2026 dollars. Production will span orders placed between 2028 and 2056. According to the fiscal 2027 shipbuilding plan, the program will begin with three initial orders. It will be followed by roughly one new battleship every other year. This estimated cost exceeds the Navy’s earlier projections for a conventional design. At the heart of the plan is the Trump-class BBGN. It is a massive vessel with a displacement of at least 35,000 tons. Its length ranges from 840 to 880 feet. It would serve as the largest surface combatant built for the Navy since the end of World War II.
The higher initial expenditure comes with the expectation of long-term savings. These savings would come through reduced operating expenses. Particularly, the elimination of the need to purchase and consume large quantities of conventional fuel is expected. However, the CBO emphasized it lacks sufficient data. It cannot calculate these potential savings until the ship’s detailed design is fully established. Also, propulsion requirements must be established.
Design and industrial challenges
The Trump-class battleship is set to feature a formidable arsenal. It includes 128 Mark 41 vertical-launch cells. It also includes 12 Conventional Prompt Strike hypersonic missiles. It includes a range of other offensive and defensive weaponry. These would include nuclear-armed sea-launched cruise missiles. High-powered lasers and rail guns would also be part of the arsenal. Various defensive systems would be included. The battleship is designed to replace the Navy’s planned DDG(X) destroyer. This is a smaller platform that, in the Navy’s view, might compromise future capabilities. This is due to its limited size and payload capacity. A single battleship would cost as much as five new DDG-51 destroyers. This highlights the massive investment the project represents.
Newport News Shipbuilding would be responsible for final assembly of the Trump-class battleship. It is the only yard certified to build nuclear-powered surface ships. Other potential shipyards, such as Bath Iron Works and Ingalls Shipbuilding, could contribute module production. They would not be able to perform final construction. This is due to the lack of nuclear certification. These scheduling and capacity constraints are already straining the Navy’s shipbuilding pipeline. The production timelines for various platforms have expanded. Attack submarines, destroyers, and large amphibious ships are affected. Production timelines have expanded from an average of five to six years in the early 2000s. They now take nine to 11 years today.
Strategic shift and financial pressure
The 2027 shipbuilding plan marks a significant shift in the Navy’s strategy, with the number of large surface combatants rising from 51 in the 2025 plan to 72 in the current plan. This increase is backed by a substantial boost in annual funding for large surface ships, moving from $6.9 billion to $15.2 billion. The CBO has warned that beginning construction before the design process is complete could result in costly rework, schedule delays, and further cost overruns. These risks are particularly acute given the complex nature of the battleship design and the challenges associated with scaling up production.
The U.S. Navy aims to use cutting-edge digital engineering and artificial intelligence-enabled tools to mitigate cost and schedule risks from the outset. However, the final price of the battleship is closely tied to its size and configuration. A reduction in displacement to 30,000 tons could cut the lead ship’s cost by about 13%, but increasing the displacement to 41,000 tons would raise the cost by 16%. Advanced weapons systems and the desire for higher survivability may also push the total budget beyond the current CBO estimate. The industrial base is already under strain, with the new battleship program adding to the pressure on an already limited number of shipyards capable of handling such a massive construction workload.
