Davison Army Air Field — Fort Belvoir, United States

At Fort Belvoir, Virginia, Davison Army Air Field operates under the code DAA, a military airfield located in Fairfax County just south of Washington, D.C. The field has long supported priority airlift for Army leadership and government functions in the National Capital Region, given its proximity to the Pentagon and federal offices, and it hosts both fixed-wing and rotary-wing operations tied to Army aviation units. DAA's role is primarily administrative and operational support rather than public commercial travel, distinguishing it from the civilian airports serving the broader D.C. area like Reagan National or Dulles. Its location within Fort Belvoir keeps access restricted to military and authorized personnel.
