Marietta Army Airfield remained open after the war and became the home of Georgia Air National Guard (ANG) and Air Force Reserve units. The first post-war ANG unit, the 128th Fighter Squadron, activated at Marietta on 20 August 1946, with P-47 Thunderbolts. This was followed by the activation of the headquarters of the 116th Fighter Group on 9 September and the activation of the headquarters of the 54th Fighter Wing which commanded 56 units of the Air National Guard throughout the Southeastern states.
