KC-10A Extender

The McDonnell Douglas KC-10 Extender is an American aerial refueling tanker aircraft operated by the United States Air Force (USAF). A military version of the three-engined DC-10 airliner, the KC-10 was developed from the Advanced Tanker Cargo Aircraft Program.[N 1] It 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.


The two Dutch KDC-10s are used for both refueling and transport.[25] They are stationed on Eindhoven Airport as part of the 334th Transport Squadron. Of the 5,500 hours flown in the first 3 years of use, the aircraft were used in their tanker role for 50% of the time. Besides being used by the air force and NATO allies, the KDC-10s are also used to support peacekeeping and humanitarian aid operations. Of the first three years, 32% of the flight hours were used for peacekeeping and humanitarian aid.[12]

In this function, the aircraft have been deployed to Kosovo to evacuate refugees, to the Caribbean and Central America to provide humanitarian aid after the hurricanes
