Editing Dahlgren, Virginia (section)

== History ==
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.<ref>{{cite web|last=Wagner|first=Gary R.|title=Navy Transfers Space Surveillance Mission to Air Force|url=http://www.navy.mil/submit/display.asp?story_id=15597|publisher=U.S. Navy|access-date=2013-08-24|archive-date=2015-01-03|archive-url=https://web.archive.org/web/20150103104927/http://www.navy.mil/submit/display.asp?story_id=15597|url-status=dead}}</ref> The [[Aegis Combat System|AEGIS]] Training and Readiness Center is currently a tenant command at NSA-SP.
