General Dynamics wins U.S. Navy’s $5.1B Deal for Columbia-Class Subs

The U.S. Navy awarded General Dynamics Electric Boat (GDEB) a contract modification worth $5.1-billion for the Columbia class of submarines, the nation’s next-generation sea-based strategic deterrent.

Electric Boat is the prime contractor on the Columbia program, which will replace the aging Ohio class ballistic missile submarines. The District of Columbia (SSBN 826) and Wisconsin (SSBN 827) are presently under construction.

The contract modification has a value of $5,134,324,189. Work will be performed in Groton, Connecticut; Quonset Point, Rhode Island; and Newport News, Virginia; and is expected to be completed by October 2030. The award funds advance procurement and advance construction of critical components and material to support Build II (the next five ships in the class), efforts to support continuous missile tube production, enhancements to develop the Submarine Industrial Base, and sustained class maintenance and support.

At 560 feet long with a displacement of nearly 21,000 tons, the submarines of the Columbia class will be the largest ever built by the United States. Ships of the Columbia class will have a fuel core that will power the submarine for its entire service life, eliminating the need for a mid-service refueling.

Electric Boat will deliver the lead ship to the Navy in 2027.
