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 host command for the Navy’s fleet throughout West Puget Sound and to provide base operating services, including support for both surface ships and submarines homeported at Bremerton and Bangor. NB Kitsap also provides service, programs, and facilities to meet the needs of their hosted warfighting commands, tenant activities, crew, and employees. NB Kitsap is the largest naval organization in Navy Region Northwest and is composed of installations in Bremerton, Bangor and Keyport. Naval Base Kitsap was the recipient of the 2005 Commander in Chief's Award for Installation Excellence - the Best Base in the U.S. Navy.

Bangor Annex

NSB Bangor's military history began in 1942 when it became a site for shipping ammunition to the Pacific theater during World War II. After the Navy purchased 7,676 acres (31 km²) on Hood Canal near the town of Bangor for approximately $18.7 million, the U.S. Naval Magazine was established June 5, 1944, and began operations in January 1945.

From World War II, and through the Korean and Vietnam conflicts until January 1973, Bangor continued its role as a U.S. Ammunition Depot responsible for shipping conventional weapons abroad.

The Navy announced the selection of Bangor as homeport for the first squadron of Trident submarines in 1973. On February 1, 1977, the SUBASE was officially activated. Naval Base Kitsap includes the Strategic Weapons Facility Pacific which services the Trident missiles carried by the submarines.
