KC-10A Extender

The KC-10A Extender is an advanced tanker and cargo aircraft designed to provide increased global mobility for US Armed Forces. It can transport up to 75 people and nearly 170,000 pounds of cargo a distance of about 4,400 miles unrefueled. The KC-10 has three large fuel tanks under the cargo floor as well as three main wing fuel tanks. Combined the 6 tanks carry more than 356,000 pounds of fuel, almost twice as much as the KC-135 Stratotanker. It uses an aerial refueling boom, or a hose and drogue centerline refueling system, to refuel a wide variety of military aircraft within the same mission. During refueling operations the fuel is transferred at a maximum rate of 1,100 gallons per minute using the boom, while the hose and drogue can refuel at a maximum rate of 470 gallons per minute. In addition, the KC-10 can be be in-flight refueled by another KC-10 or a KC-135 tanker aircraft to increase its delivery range. The KC-10 has a crew of 4 people: the pilot, copilot, flight engineer and boom operator. The KC-10A Extender is a derivative of commercial DC-10 aircraft and was deployed within the US Air Force in 1981. During operation Desert Shield in 1990 and Desert Storm in 1991, this aircraft provided in-flight refueling for US Air Force aircraft making possible the rapid deployment of US military forces to the Persian Gulf theater of operations. During the war the KC-10 and KC-135 tankers delivered about 125 million of gallons in 51,700 separate refueling operations.
