Davison Army Airfield

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.

The Civil Air Patrol National Capitol Wing uses a small tower for use during exercises and flights, and bases their four Cessna 172 and 182s there.

A helicopter operating a training flight from Davison was involved in the 2025 Potomac River mid-air collision in late January.
