Each French Air Force squadron stores some of its planes for a while thereby artificially prolong the life of the fleet and better material management.

Under occupation, the German army, owner, undertook infrastructure projects including the construction of dispersal areas called "daisies" and the track.

Largely due to the presence of the Me 262, Châteaudun became a major target of USAAF Ninth Air Force B-26 Marauder medium bombers and P-47 Thunderbolts mostly with 500-pound General-Purpose bombs; unguided rockets and .50 caliber machine gun sweeps to attack the German jets on the ground.

Initially, the 422d Night Fighter Squadron moved in and provided an air defense with P-61 Black Widows from 28 August to 16 September 1944.

With the combat units moving east with the front lines, Châteaudun became a transport airfield, with the 439th Troop Carrier Group flying C-47 Skytrains from the field from 4 November 1944 until 7 September 1945.

In 1967, during the period of tension précéding the Six-Day War, fifty Dassault Mirage 5 jets ordered by Israel were stored on the base of Chateaudun.

Today, the remains of World War II bomb craters are very evident in the grass areas of the airfield, as well as the abandoned 05/23 secondary runway in which the wartime patching with asphalt is still visible.

Element Air Reattache 279 (EAR 279) retained the mission of aircraft storage, as well as aerial activity (the field being open two days a week).
