The Mare Island Naval Shipyard (MINSY or MINS) was the first United States Navy base established on the Pacific Ocean and was in service 142 years from 1854 to 1996. It is located on Mare Island, 23 miles (37 km) northeast of San Francisco, in Vallejo, California. MINSY made a name for itself as the premier U.S. West Coast submarine port as well as serving as the controlling force in San Francisco Bay Area shipbuilding efforts during World War II.
The naval base was closed on 31 March 1996, with more than 7,500 civilians on its payroll, and has gone through several redevelopment phases. It was registered as a California Historical Landmark in 1960, and parts of it were declared a National Historic Landmark District in 1975.
