Concord Naval Weapons Station was a military base established in 1942 north of the city of Concord, California at the shore of the Sacramento River where it widens into Suisun Bay. The station functioned as a World War II armament storage depot, supplying ships at Port Chicago. The Concord NWS continued to support war efforts during the Korean War, the Vietnam War and the Gulf War, processing and shipping thousands of tons of materiel out across the Pacific Ocean. During World War II it also had a Naval Outlying Field at its southern edge of the base. It ceased being an operating airfield after World War II.
