Extender Flight Refueller

It is a fact of life that no matter how potent a particular fighter or bomber are in combat to provide the United States with its global response they require a force of in-flight refueling aircraft. As an adjunct to its fleet of ageing Boeing KC-135's the McDonnell KC-10 Extender a derivative of the DC-10 airliner provides the USAF with a true multi-role capability as an refueller and tanker-transport.
