The mighty KC-135
A U.S. Air Force KC-135 Stratotanker from the 22nd Expeditionary Air Refueling Squadron rests on the Incirlik Air Base flight line during an aircraft tour at Incirlik Air Base, Turkey, Aug. 17, 2020. While the KC-135 will eventually be succeeded by the new KC-46 Pegasus, the more than 300 KC-135s in service will continue to serve as the U.S. Air Force’s primary air refueler for decades to come.
