Concord Naval Weapons Station

Base Background

Location 5110, Port Chicago Highway, Concord, California, 94520, United States
Years of Operation 1942-2007

The Concord Naval Weapons Station first opened in 1942 as an annex to the Mare Island Naval Shipyard and Mare Island magazine. During World War II, the base stored and supplied ships for the war effort. The station then had a role in shipping ammunition across the Pacific during the Korean, Vietnam, and Gulf Wars.

This station is well known for the Port Chicago Disaster, which occurred in 1944. During this incident, an explosive detonated and killed 320 people. Over 200 of these individuals were African American sailors. This incident is known as the largest stateside disaster of World War II.
