Davison Army Airfield or Davison AAF (IATA: DAA, ICAO: KDAA, FAA LID: DAA) is a military use airport of the United States Army in Fairfax County, Virginia, serving adjacent Fort Belvoir. Located fifteen miles (24 km) southwest of Washington, D.C., the facility was named for noted World War II aviation engineer Brig. Gen. Donald Angus Davison.
The airfield provided support for Army One from 1957 to 1976 for presidents Dwight Eisenhower, John F. Kennedy, Lyndon Johnson, Richard Nixon, and Gerald Ford. Its role of support for the presidential helicopter ended in 1976 when that responsibility was transferred entirely to the U.S. Marine Corps. The 12th Aviation Battalion (part of The Army Aviation Brigade, TAAB) now operates Davison AAF and the Pentagon helicopter pad. The battalion's 18 UH-60 Blackhawks, including four VH-60 models ("Gold Tops"), is responsible for priority regional transport for U.S. Army and Pentagon senior leadership.
