EADS/Northrop Grumman KC-45
The EADS/Northrop Grumman KC-45 was a proposed aerial refueling tanker aircraft based on the Airbus A330 MRTT. The United States Air Force (USAF) had ordered 179 KC-45As in the first stage of replacing the aging Boeing KC-135 Stratotanker tankers currently in service. However, the contest was reopened in July 2008, after Boeing's protest of the award was upheld.
