The purpose of the analysis was to provide a clear comparison between the KC-767 Advanced Tanker (AT), based on the 767, and its major competitor in the U.S. Air Force's KC-135 Tanker Replacement Program. The winner of the KC-X competition will begin recapitalizing the service's aging refueling inventory by building 179 next-generation tankers. The study showed that the 767 fleet burned 24 percent less fuel than the A-330s and would save approximately $14.6 billion in fuel costs. That number is significant since the Air Force spent approximately $6.6 billion on aviation fuel costs in 2006. [/quote] La guerre a commencé... :? Bon, un peu normal qu'un avion qui pèse 50 tonnes de plus au décollage consomme plus non ? D'autant qu'il emporte bien plus de kérosène et de fret...[/quote]
