Main image

The Port Chicago Naval Magazine National Memorial commemorates the 1944 munitions explosion at the Port Chicago Naval Magazine and the men and civilians who died as a result. It recognizes the event’s role in changing safety practices and its significance in the history of racial justice in the U.S. Navy.

The memorial area includes markers and interpretive panels that summarize the July 17, 1944 explosion and the subsequent trials and reforms. It is a small site used for remembrance rather than extensive visitor facilities.

The explosion occurred while ships were being loaded with munitions; about 320 people were killed and hundreds were wounded, many of them African American sailors. The disaster led to the largest naval mutiny trial in U.S. history and increased attention to segregation and working conditions in the armed forces.

The memorial sits on the northern margin of Suisun Bay in Contra Costa County, California, near the former townsite of Port Chicago and roughly 30 miles northeast of San Francisco. The nearest communities are Concord and Martinez, and the site is accessed by road from local highways.

  • Date and casualties: The explosion occurred on July 17, 1944, killing about 320 people and injuring many others.
  • Administration: The site is administered by the National Park Service and contains interpretive markers remembering the explosion and its social and legal aftermath.
