Kc-10 Extender




]]
The KC-10 Extender is a tanker aircraft in service with the United States Air Force . Though the 59 Extenders currently in service are greatly outnumbered by the KC-135 Stratotanker , the KC-10 has a significantly larger fuel capacity. KC-10s are currently stationed primarily at McGuire Air Force Base in New Jersey and Travis Air Force Base in California .

Beginning with the Vietnam War doubts began to be raised about the ability of the 700+ strong KC-135 fleet to meet the needs of the United States ’ global commitments. The air-refueling fleet was deployed to South-East Asia in support of tactical aircraft and strategic bombers, while maintaining the US-based support of the nuclear bomber fleet. As a result, studies began into the feasibility of acquiring an Air-to-air Tanker with a greater capability than the KC-135 fleet, but did not progress well due to lack of funding.

The Yom Kippur War in 1973 demonstrated the necessity of adequate air-refueling capabilities. Denied landing rights in Europe, USAF C-5 Galaxy s were forced to carry a fraction of their maximum payload on direct flights from the continental United States to Israel . As a result C-5 crews were soon trained in aerial-refueling and the Department Of Defense concluded that a more advanced tanker was needed.

In (which lost out to the C-5 in a previous military contract), the McDonnell Douglas DC-10 , and the Lockheed L-1011 . Donald Rumsfeld , in his first posting to the Pentagon , selected the DC-10 in 1976 .

Conversion to the KC-10 involved only minor modifications to the DC-10, the largest of which was the addition of a boom control station in the rear of the fuselage and extra fuel tanks under the main deck. First deliveries to the Strategic Air Command (then in control of AAR assets) commenced in 1981 .

In the AAR role the KC-10 has been operated largely in the same way as the RAF ’s Tristar (L-1011s), i.e. the strategic refueling of large number of tactical aircraft on ferry flights and the refueling of other strategic transport aircraft. Conversely, the KC-135 and RAF VC-10 fleets have operated largely in the in-theatre tactical role. Excellent examples of the KC-10's strategic role are:

The Royal Netherlands Air Force operates two KDC-10s - former civil aircraft modified to the same standard as the KC-10 - in the aerial refueling role and is acquiring an additional aircraft to serve in the strategic transport role.

The KC-10 is currently the world's longest-ranged production aircraft, and will continue to hold that record past the introduction of the Boeing 777-200LR , though future 777 variants may range further.
