Châteaudun Airfield (ICAO: LFOC) is a military airfield located near the town of Châteaudun in the Eure-et-Loir department of north-central France. It has historically served as a French Air and Space Force base and is not a commercial passenger airport. The airfield has roots dating back to World War II, when it was used by both German and Allied forces during the conflict. Today it primarily supports military aviation activities and general aviation operations, with no scheduled commercial airline services. The site is also associated with aircraft storage and maintenance functions for the French military, and access by the general public is restricted given its military nature.
