Vint Hill Farms, Virginia

Former military communication station established in 1942 on a 701-acre site by the Army's Signals Intelligence Service, to intercept enemy messages during WWII. After the war, it served as an installation specializing in intelligence and electronic warfare research, development, and training. The base was closed by BRAC in 1997 and transferred to a civilian development organization. 2,200 personnel were employed at Vint Hill. A major facility there now is the FAA’s Potomac Consolidated Terminal RADAR Approach Control (TRACON) office, which opened in 2002. The facility provides air traffic control service to the Baltimore-Washington and the Richmond-Charlottesville Areas, and controls the airspace over Andrews Air Force Base, BWI, Ronald Reagan, Dulles, Richmond and many other area airports. Other developments at Vint Hill include a datacenter operated by OVH, a brewery, and a small Cold War Museum, across from the Covert Café.
