The following is the Feb. 5, 2025, Congressional Research Service report, Navy Columbia (SSBN-826) Class Ballistic Missile Submarine Program: Background and Issues for Congress.
From the report
The Navy’s Columbia (SSBN-826) class ballistic missile submarine (SSBN) program is a program to design and build a class of 12 new SSBNs to replace the Navy’s current force of 14 aging Ohio-class SSBNs. Since 2013, the Navy has consistently identified the Columbia-class program as the Navy’s top priority program. The Navy procured the first Columbia-class boat in FY2021; the boat was funded with three-year incremental funding in FY2021-FY2023. The Navy procured the second Columbia-class boat in FY2024; the boat is being funded with two-year incremental funding (also called split funding) in FY2024-FY2025. The Navy wants to procure the remaining 10 boats in the program—boats 3 through 12—at a rate of one per year in FY2026-FY2035.
The Navy’s FY2025 budget submission estimates the total procurement cost of the first boat at $15,179.1 million (i.e., about $15.2 billion) and the procurement cost of the second Columbia-class boat at $9,283.1 million (i.e., about $9.3 billion). The first boat’s procurement cost is much higher than that of subsequent boats in the class because the first boat includes most of the detail design/nonrecurring engineering (DD/NRE) costs for the class. (It is a long-standing Navy budgetary practice to incorporate the DD/NRE costs for a new class of ship into the total procurement cost of the first ship in the class.) The first boat’s estimated procurement cost includes $6,557.6 million for plans, meaning (essentially) the DD/NRE costs for the class. Excluding costs for plans, the estimated hands-on construction cost of the first ship is $8,621.5 million (i.e., about $8.6 billion).
The Navy’s proposed FY2025 budget requests $3,341.2 million (i.e., about $3.3 billion) in procurement funding to complete the procurement cost of the second Columbia-class boat and $6,215.9 million (i.e., about $6.2 billion) in advance procurement (AP) funding for Columbia-class boats to be procured in FY2026 and subsequent years.
