Base aérienne 279 Châteaudun base is located approximately 3.5 kilometres southeast of Châteaudun and about 112 kilometres southwest of Paris.

The base is primarily used for aircraft storage and ferrying them to other squadrons of the Air Force. Entrepot de l’Armee de l’Air 601 was assigned to perform this mission. 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. The EAA also has the task of storing new aircraft to be used in times of war. To fulfil its mission, the EAA has the Group Maintenance, repair and storage of aircraft (GERS).
