As previously over Iraq in 1991, the entire Operation Allied Force became possible thanks to the availability of the large tanker-fleet of the US Air Force. As well as the venerable Boeing KC-135s, this included much bigger McDonnell Douglas KC-10A Extenders. A dozen of these were operated by the 305th Air Mobility Wing/92nd Air Expeditionary Wing from Moron AFB in Spain, while the example shown here – serial (8)20193 – was one of at least 15 rotated through the 60th Air Expeditionary Wing at Rhein-Main AFB in Germany. In turn, this wing was based on the HQ of the 60th Air Mobility Wing, home-based at Travis AFB, and organised into two squdrons, one equipped with KC-10As and the other with KC-135s – drawn from several different units of the USAF, AFRES and the ANG, all on temporary duty. As usual for the 1990s, the aircraft was painted in Neutral Gray (FS36173) overall, and wore only toned-down markings. (Artwork by Tom Cooper)
