The McDonnell Douglas KC-10 Extender is the military version of the three-engined DC-10 airliner operated by the United States Air Force (USAF). The KC-10 incorporates military-specific equipment for its primary roles of transport and aerial refueling. It was developed to supplement the KC-135 Stratotanker following experiences in Southeast Asia and the Middle East. The KC-10 was the second McDonnell Douglas transport aircraft to be selected by the Air Force following the C-9.
