Dahlgren is an unincorporated community and census-designated place (CDP) in King George County, Virginia, United States. The population was 2,946 at the time of the 2020 census,[3] up from 2,653 at the 2010 census,[4] and up from 997 in 2000.[5]
Since 1918, Dahlgren has been the site of a U.S. naval base named for Rear Admiral John A. Dahlgren. It was first the "U.S. Naval Proving Ground" but was renamed the "U.S. Naval Weapons Laboratory" after 1950, the "Naval Surface Weapons Center" in 1974, the "Naval Surface Warfare Center" in 1987, and the "U.S. Naval Surface Warfare Center Dahlgren Division (NSWCDD)" around 1990. In 2006, it was renamed "Naval Support Activity-South Potomac (NSA-SP)", with NSWCDD becoming a tenant command of the base. The U.S. Naval Space Surveillance Systems command was located at that base, but that responsibility was transferred to the Air Force in 2004.[6] The AEGIS Training and Readiness Center is currently a tenant command at NSA-SP. The naval base lies just east of the Dahlgren CDP within its own census-designated place, Dahlgren Center.
