Taverny Air Base

Taverny Air Base (formerly Base Aérienne 921 "Frères Mahé" de Taverny; ICAO: LFPJ) is located in the communities of Taverny and Bessancourt in the Val-d'Oise department of France, 20 km (12.4 mi) north-northwest of Paris. From 1964 to 2007 and again since 2024 it has been the headquarters of the Strategic Air Forces Command, the nuclear strike force of the French Air and Space Force, with an underground command center.

The base is divided into three tiers with an area of approximately 15 hectares:

• The first tier is underground in a former gypsum quarry beneath the Forest of Montmorency. The facility comprised the hardened command facility for the French Air Force.
• The second tier is on the surface, and provided support services for the underground command center.
• The third tier is at the top of the hill, with facilities for secure military communications.

There were no aviation facilities apart from a heliport.
