Commander Fleet Activities Yokosuka

Commander Fleet Activities Yokosuka at a glance

Commander Fleet Activities Yokosuka is a shore installation supporting the U.S. Seventh Fleet and the U.S.-Japan alliance. Its community includes forward-deployed naval organizations alongside the services required by Sailors, civilians and families. The installation's official mission emphasizes fleet service and the quality of an overseas community, bringing ship support together with healthcare, education and other shore functions.

The U.S. Navy established the activity after the Japanese base was transferred to Allied control in 1945. Ship repair became a major part of its role in the years that followed. Yokosuka's location at the entrance to Tokyo Bay makes it a distinct naval community within the greater Tokyo region. Current installation pages should be used for ship and tenant information, since historical profiles can retain former assignments.
