The KC-10A Extender is a US Air Force advanced tanker and cargo aircraft whose primary mission is aerial refueling. Within the same mission, it can refuel US and coalition forces aircraft using either a hose and drogue centerline refueling system or an advanced aerial refueling boom, and it can also be refueled by another KC-10 or a KC-135. The aircraft is configured to carry military cargo and personnel at the same time. Since 1981, the KC-10 has been an important part of air fueling in war and peace, improving global mobility for US armed forces. KC-10A serial number 84-0191 was instrumental in 1986 during OPERATION EL DORADO CANYON, serving as a mother ship for an attacking element of US F-111s, including the F-111F also on display in the museum, as they struck the command center for a Libyan terrorist network in Tripoli. For the first time since WWII, US aircraft took off from Royal Air Force bases in the United Kingdom for a bombing mission, and the KC-10's large fuel capacity allowed the strike force aircraft to refuel eight times during the mission. The raid demonstrated the US's capabilities for long-range precision strikes. This aircraft arrived in April 2024 from its last duty station at Travis AFB, California. It has a crew of four, three General Electric CF6-50C2 turbofans each producing 52,500 pounds of thrust, a maximum fuel load of 356,000 pounds, a maximum cargo load of 170,000 pounds, and a range of 4,400 miles with cargo or 11,500 miles without cargo unrefueled.
