Welcome to Mare Island Dry Dock!

Mare Island is the oldest shipyard facility on the West Coast, located in Vallejo, California – 23 miles northeast of San Francisco.  It was established in 1854 as the first United States Naval base on the Pacific Ocean. Mare Island served as a major naval shipbuilding and repair facility for over 140 years.  Naval operations cased in 1996 and Mare Island was decommissioned.
