Nancy-Ochey Air Base, designated BA 133, is a military airfield operated by the French Air and Space Force (Armée de l'Air et de l'Espace). Located near the village of Thuilley-aux-Groseilles in the Meurthe-et-Moselle department of northeastern France, it serves no scheduled civilian air traffic. The base has historically been home to fighter and strike aircraft, and has played a role in French nuclear deterrence missions. It is one of several French air bases in the Grand Est region with a long operational history dating back to the Cold War era. As a restricted military installation, BA 133 is not open to the public and has no commercial passenger facilities. It holds the ICAO code LFSO but no IATA code, reflecting its exclusively military function.
