SAN DIEGO - The U.S. Navy and its industry partners are implementing an aggressive acceleration plan to deliver the lead Columbia class nuclear ballistic missile submarine, District of Columbia (SSBN-826), by 2028. Speaking at the WEST 2026 conference, Rear Adm. Todd Weeks, Program Executive Officer for Strategic Submarines, confirmed the vessel is approximately 65 percent complete. The push follows a series of production delays involving bow and stern sections and turbine components that had previously threatened to push delivery into 2029.
Under a recovery initiative dubbed the "A-26" plan, shipbuilders General Dynamics Electric Boat and HII’s Newport News Shipbuilding successfully delivered all 26 major modules to the final assembly yard in Groton, Connecticut, by the end of last year. The Navy expects the submarine to achieve a completed pressure hull by the end of 2026, with a scheduled launch into the water the following year.
The program remains under significant pressure to maintain the required fleet of 12 ballistic missile submarines for the nation's sea-based nuclear deterrent. To mitigate risks associated with the transition from the retiring Ohio class, the Navy is currently evaluating life extensions for five older hulls. Despite the challenges with the lead ship, the second boat in the class, Wisconsin (SSBN-827), is 35 percent complete and currently on schedule, with the program expected to reach full serial production by 2031.
