The Boeing KC-767 is a military aerial refueling and strategic transport aircraft developed from the Boeing 767-200ER. The tanker received the designation KC-767A in 2002, after being selected by the US Air Force initially to replace older KC-135Es. In December 2003, the contract was frozen and later canceled due to corruption allegations.
The tanker has been developed for the Italian and Japanese air forces, who ordered four tankers each. Financing of the development of the aircraft has largely been borne by Boeing, in that it hoped to get major orders from the U.S. Air Force. Boeing's revised KC-767 proposal to the U.S. Air Force was selected in February 2011 for the KC-X program.
