A modified DC-10, the KC-10A entered service in 1981. The KC-10A Extender is an advanced tanker and cargo aircraft designed to provide increased global mobility. The KC-10A can transport up to 75 people and about 170,000 pounds of cargo a distance of about 4,400 miles unrefueled.
The KC-10's six fuel tanks can carry more than 356,000 pounds of fuel, almost twice as much as the KC-135 Stratotanker. Using either an aerial refueling boom, or a hose and drogue refueling system, the KC-10A can refuel a wide variety of military aircraft within the same mission. The aircraft is outfitted with special lighting for operations at night.
The boom operator controls refueling operations through a digital fly-by-wire system. Sitting in the rear of the aircraft, the operator can see the receiver aircraft through a wide window. During boom refueling operations, fuel is transferred to the receiver at a maximum rate of 1,100 gallons per minute and the hose and drogue refueling maximum rate is 470 gallons per minute. The KC-10A can be air-refueled by a KC-135 or another KC-10A to expand its delivery range.
The KC-10A fleet is being modified to add wing-mounted pods to further enhance aerial refueling capabilities. They are operated by the 305th Air Mobility Wing, McGuire AFB, NJ, and the 60th Air Mobility Wing, Travis AFB, CA.
