During the Pacific War, the Yokosuka Naval Arsenal was attacked by one bomber during the Doolittle Raid on 18 April 1942 and by a large force of carrier aircraft during the Attack on Yokosuka on 18 July 1945. The facilities were seized by the Allied forces at the end of World War II, and on 15 October 1945 the Yokosuka Naval Arsenal was officially abolished.
