Hahn Air Base was a frontline NATO facility in Germany for over 40 years during the Cold War (former ICAO EDAH, now EDFH as Frankfurt-Hahn Airport). It is located 10 km (6.2 mi) from the town of Kirchberg and 20 km (12 mi) from the town of Simmern, and 2 km from the tiny village of Hahn in the Rhein-Hunsrück district of Rhineland-Palatinate in west-central Germany.
It was the home of the United States Air Force 50th Fighter Wing (in various designations) for most of those years as part of the United States Air Forces in Europe (USAFE). It was one of several USAFE bases in Germany (Zweibrucken Air Base, Ramstein, Sembach, Bitburg, Spangdahlem, and Rhein-Main) all within 100 km (62 mi) of each other. Beyond their location in the heart of US troop concentrations, these air bases were well situated to reach all locations within Europe and the Mediterranean region.
