RAF Andover (IATA: ADV, ICAO: EGWA) is a former Royal Flying Corps and Royal Air Force station in England, 2 miles (3.2 km) west of Andover, Hampshire. As well as RFC and RAF units, units of the Aviation Section, U.S. Signal Corps, Royal Canadian Air Force, United States Army Air Forces, and the Air Transport Auxiliary were also stationed at the airfield. The RAF station closed in 1977 and the site was later redeveloped. In 2009 part of it became Marlborough Lines, home to the Headquarters of the British Army.
