Romilly Sur Seine Airfield

The closure was a result of a large-scale restructuring of the French Armed Forces following the end of the Cold War. The decision was primarily driven by economic reasons and the strategic need to consolidate military assets and reduce the number of bases.

The site has been completely redeveloped and repurposed. A large portion of the former airfield, including the main runway areas, has been converted into one of France's largest photovoltaic power plants (solar farms). The remaining area has been transformed into a large industrial and commercial zone called 'Aéromia'. Many of the original hangars and military buildings have been refurbished and are now used by various businesses. The original aviation infrastructure is no longer functional.

Romilly-sur-Seine Airfield, officially known as Base Aérienne 912 'Commandant-Rozanoff' (BA 912), had a long and rich history.

- **Establishment:** It was one of France's oldest airfields, created in 1912 for military aviation.
- **World War I:** It served as a crucial training, repair, and logistics center for the French air services.
- **Interwar Period:** It became a major industrial site for aircraft construction and maintenance.
- **World War II:** After the Fall of France in 1940, the airfield was seized and used by the German Luftwaffe as a bomber base, housing units like Kampfgeschwader 54 equipped with Junkers Ju 88s. After its liberation by Allied forces in August 1944, the USAAF Ninth Air Force designated it as Advanced Landing Ground 'A-60', using it for fighter and transport squadrons.
- **Post-War:** It was returned to the French Air Force (Armée de l'Air) and became a major maintenance and supply depot (Entrepôt de l'Armée de l'Air 601) and a key industrial site (AIA). It was named in honor of Constantin Rozanoff, a celebrated French test pilot.

There are no known plans or prospects for reopening the site as an airport. The extensive and permanent redevelopment into a solar farm and an industrial park makes a return to aviation activities virtually impossible.
