The Columbia-class submarine is a planned ballistic missile attack submarine for the United States Navy (USN) intended to succeed the Ohio-class boats. Research and development work on the program has been underway for several years, and advance procurement (AP) funding for the first boat began in FY2017.

Ohio-class submarines are a product of the latter Cold War years, built from 1976 to 1997, and number eighteen completed boats (2018). The Navy’s FY2021 budget submission estimates the procurement cost of this boat at $9,326.1 million (i.e., about $9.3 billion) in then-year dollars. The Navy has identified the Columbia-class program as the Navy’s top priority program.

The Navy has identified the Columbia-class program as the Navy’s top priority program. - Blue Water Operations The Navy has identified the Columbia-class program as the Navy’s top priority program. (It is a longstanding 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 initial operating boat of the class will be christened USS Columbia (SSBN-826). The Navy’s proposed FY2021 budget requests $1,123.2 million in AP funding for the Columbia-class program, of which $1,028.0 million (i.e., about $1.0 billion) is for the second boat and $95.2 million is for the third and subsequent boats in the program.The Navy’s FY2021 budget submission estimates the total procurement cost of the 12-ship class at $109.8 billion in then-year dollars.Issues for Congress for the Columbia-class program include the following:Report on the Columbia-class Nuclear Ballistic Missile Submarine Program We do not sell any of the items showcased on this site.

The Navy wants to procure the first Columbia-class boat in FY2021. It is planned that the series will begin construction sometime in 2021 and the first boat will enter service in the following decade, possible in 2031. The Columbia (SSBN-826) class program is a program to design and build a class of 12 new ballistic missile submarines (SSBNs) to replace the Navy’s current force of 14 aging Ohio-class SSBNs. The Navy wants to procure the first Columbia-class boat in FY2021. Excluding costs for plans, the estimated hands-on construction cost of the first ship is $8,385.7 million (i.e., about $8.4 billion).
