Eskişehir Air Base — Eskişehir, Turkey

ESK identifies Eskişehir Air Base, a Turkish Air Force installation serving the city of Eskişehir in northwest Anatolia. The base has long hosted transport squadrons and training operations, and it also handles limited civilian and government flights alongside its military role. Eskişehir itself is a major hub for aviation education in Turkey, home to Anadolu University's flight training programs, and the air base has historically supported that ecosystem. Because it is primarily a defense facility rather than a commercial gateway, scheduled passenger service is minimal or absent, with most movements tied to Turkish Armed Forces logistics, exercises, and occasional NATO-related activity in the region.
