The plane was also offered to the U.S. Air Force as a replacement for some of their Boeing KC-135 'Stratotankers'. Eventually in 2002, they chose Boeing's offering: the KC-767. But this order was cancelled after a lot of political controversy. In 2006, the Air Force started again. Boeing again offered the KC-767 and Airbus teamed up with Northrop Grumman to make the KC-30. This time, they chose the KC-30 and renamed it the KC-45A. But Boeing complained that the ruling was not fair and the US Government Accountability Office agreed with Boeing. The bid was cancelled again. Northrop Grumman has decided not to offer the KC-45A again.
