(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.) 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 FY2023 budget submission estimates the procurement cost of the first Columbia-class boat at $15,179.1 million (i.e., about $15.2 billion) in then-year dollars, including $6,557.6 million (i.e., about $6.6 billion) in costs for plans, meaning (essentially) the detail design/nonrecurring engineering (DD/NRE) costs for the Columbia class. The Navy’s proposed FY2023 budget requests $3,079.2 million (i.e., $3.1 billion) in continued procurement funding for the first Columbia-class boat and $2,778.6 million (i.e., about $2.8 billion) in advance procurement (AP) funding for subsequent boats in the class, for a combined FY2023 procurement and AP funding request of $5,857.8 million (i.e., about $5.9 billion).

The Navy procured the first Columbia-class boat in FY2021 and wants to procure the second boat in the class in FY2024. Since 2013, the Navy has consistently identified the Columbia-class program as the Navy’s top priority program. 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. 21, 2022, Congressional Research Service report, Navy Columbia (SSBN-826) Class Ballistic Missile Submarine Program: Background and Issues for Congress.
