An-122KC KC-X proposal revealed?
Details of US Aerospace's KC-X bid may have been revealed.
August 6: An unofficial release on Russian Internet of what look like US Aerospace documents have shed some light on the proposed version of Antonov’s An-70 that is being offered for the US Air Force KC-X aerial refuelling tanker contract for 179 aircraft.
The documents reveal that the An-70’s four turboprop engines would be replaced with two large turbofans similar to the Rolls-Royce Trent 1000 and that the maximum fuel load would be 83 tonnes, bringing the all-up weight to 165 tonnes. The An-122KC as it is called would have a range of up to 2,500 miles and could also carry 33 tonnes of cargo, if the equivalent fuel load was offset. The refuelling system would comprise three hose-and-drogue units, two on the wing and one on the fuselage, plus a telescopic boom.
US Aerospace will have to wait until the US Government Accountability Office (GAO) has considered if its claim against the US Air Force for “unfair treatment” for rejecting its bid for lateness is valid before it knows if it is still in the race. As the GAO is unlikely to come to a decision much before the November deadline for the air force to decide on a winner, it could force the whole KC-X programme to be delayed by months yet again.
