Naval Operating Base Terminal Island, (NOB Terminal Island) was United States Navy base founded on 25 September 1941 to support the World War II efforts in the Pacific War. Naval Operating Base Terminal Island was founded by combining Naval Facilities in cities of San Pedro, Long Beach and Wilmington, California under one command. Much of the base was on the man-made Terminal Island, and harbor in San Pedro Bay. The harbor was made through the construction of a large breakwater system.[1][2]
