The EADS-Northrop Grumman KC-45 is a proposed aerial refueling tanker aircraft based on the Airbus A330 MRTT (KC-30) a derivative of the civil A330-200. The United States Air Force (USAF) had ordered 179 KC-45As in the first stage of replacing the aging KC-135 tankers currently in service. However the contest was reopened in July 2008 after Boeing's protest of the award was upheld.
