The Navy plans to spend up to $250 million to extend and modernize a pier at Naval Base Kitsap-Bangor to serve new ballistic missile and attack submarines coming into the fleet in the next decade. The base is homeport to the Navy’s largest number of ballistic missile submarines. The work will enable the base to homeport more of the new Columbia-class ballistic missile submarines and Virginia-class attack submarines that the Navy has said will join the fleet in the next decade.
