The United States Navy has awarded General Dynamics Electric Boat a $15.38 billion contract modification to support the Columbia-class ballistic missile submarine program, including design work, lead yard support, and industrial base development.
According to the U.S. Department of War, the award covers additional Columbia-class submarine design activities, class lead yard support, sustainment, and integrated enterprise planning initiatives. It also includes supplier development efforts aimed at strengthening the submarine industrial base to support both Columbia-class and Virginia-class submarine production.
The contract, issued by Naval Sea Systems Command in Washington, D.C., modifies a previously awarded agreement (N00024-17-C-2117). Work will be carried out across multiple U.S. locations, including Groton, Connecticut, where 21% of the work will take place, as well as Newport News, Virginia; Sunnyvale, California; and several other industrial centers.
The effort is expected to continue through June 2035, reflecting the long-term scope and complexity of the Columbia-class program.
Funding for the contract includes $3.07 billion from fiscal 2026 national sea-based deterrence funds, along with additional allocations from fiscal 2025 and 2026 research, development, test, and evaluation accounts and maritime industrial base funds. A total of $3.14 billion will expire at the end of the current fiscal year.
The Columbia-class program is central to the Navy’s effort to maintain a continuous at-sea nuclear deterrent, replacing the Ohio-class submarines that have formed the backbone of the United States’ sea-based nuclear forces since the 1980s.
According to the Government Accountability Office, the Columbia class is designed to be the largest and most complex submarine ever procured by the Navy. The program represents the first new class of U.S. ballistic missile submarines developed since the 1990s.
From a technical standpoint, ballistic missile submarines are designed to operate undetected while carrying nuclear-armed missiles, providing a survivable second-strike capability as part of the nuclear triad. Their stealth, endurance, and global reach make them a critical component of strategic deterrence.
According to the announcement, the industrial base development work is intended to support the Navy’s plan for serial production of both Columbia-class and Virginia-class submarines. This reflects a broader effort to increase output and ensure that multiple submarine programs can proceed in parallel without delays.
The Columbia-class program also involves coordination between major shipbuilders, including General Dynamics Electric Boat and Huntington Ingalls Industries’ Newport News Shipbuilding, which are jointly responsible for construction and integration of key components.
The contract modification supports the role of Electric Boat as the lead yard for the class, responsible for design authority and coordination across the industrial network.
