Naval Base Kitsap is a U.S. Navy base located on the Kitsap Peninsula in Washington state. It was created in 2004 by merging the former Naval Station Bremerton with Naval Submarine Base Bangor. The Mission of Naval Base Kitsap is to serve as the home base for the Navy’s fleet throughout West Puget Sound and to provide base operating services, including support for both surface ships and Fleet Ballistic Missile and other nuclear submarines having their home ports at Bremerton and Bangor.
