Remplacement des ravitailleurs US

En fait, c'est bien EADS (via CASA) qui mène les tests.

Boeing offrait aussi le 777, domage que cet voix n'aboutti pas!

Ben ils ont choisi de développer le KC-767. C'est déjà pas mal, non ?

2 problèmes (en tout cas à ma connaissance) : le coût (c'est le principal reproche qu'ils font au KC-30, difficile de se renier en suivant finalement l'option choisie par Airbus) et surtout les délais de livraisons, les chaines de 777 étant au taquet pour plusieurs années.

D'un autre côté, ça aurait été un sacré tanker.

Rien qu'en capacité interne du modèle civil 777-200LR, on est à 200 000 litres de kérosène. On serait probablement arriver pas loin des 250 000 litres en version KC-777.

En attendant le remplacement des KC-135 :

Boeing Submits Final KC-767 Advanced Tanker Proposal to U.S. Air Force

KC-X win would shift A330 Freighter assembly to US

Boeing 767 More Fuel Efficient than Airbus 330, Analysis Finds

The study conducted by the independent aviation research company, and funded by Boeing, used published data to calculate the fuel consumption of flying a fleet of 179 767-200ER and Airbus 330-200 airplanes over a 40-year service life. 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.

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…

Comme on est (je suis) dans le déterrage de topic en ce moment :

Boeing Completes First KC-767 Tanker Night Refueling

ST. LOUIS, Jan. 29, 2008 – The Boeing Company [NYSE: BA] made KC-767 program history Jan. 26 when one if its aircrews successfully transferred fuel from a KC-767 tanker aircraft to an F-15E at night – the first nighttime refueling ever accomplished on a KC-767.

The new tanker, scheduled for delivery to Japan's Air Self-Defense Force (JASDF) early this year, departed McConnell Air Force Base, adjacent to the Boeing Integrated Defense Systems Wichita, Kan., facility, and flew a 3-hour and 9 minute flight. Operating in the skies over Missouri, the aircrew connected the KC-767s fifth-generation, fly-by-wire boom (a telescoping tube used to deliver fuel to military aircraft) to an F-15E 11 times during dusk and night conditions and successfully offloaded fuel before returning safely. The company uses F-15E1 under a cooperative research and development agreement with the U.S. Air Force.

"Using our remote vision system, I was impressed with the quality of the picture and my ability to accurately see details of the F-15E and its refueling receptacle at night," said Rickey Kahler, Boeing KC-767 chief test boom operator.

The Japan KC-767 Tanker, a military derivative of the proven 767-200 commercial airplane, was selected over its competitor, the Airbus A-310, in a direct competition in 2001.

Its advanced boom builds on the aerodynamic shape and size of previous systems and provides more precise and responsive controls to the operator. With 2,600 fewer parts than previous booms, it also is easier to maintain.

"This milestone highlighted the KC-767's ability to perform refueling operations under all lighting conditions and demonstrated an upgrade to the lighting system we promised our Japan customer," said George Hildebrand, Boeing KC-767 Japan program manager."Our next step is to complete the remaining Federal Aviation Administration certifications and deliver two new tankers to Japan early this year."

Boeing has built nearly 2,000 tankers in its history and is under contract to build four KC-767s for Japan. The JASDF has selected the convertible freighter configuration, which will provide flexibility in carrying cargo or passengers, while maintaining its primary role as an aerial tanker.

Boeing also is building four KC-767s for Italy with delivery of the first two tankers in the second quarter of 2008. To date, Boeing has logged more than 350 flights accumulating more than 1,000 flight hours on the KC-767.

In addition to flight-testing the KC-767 for international customers, Boeing is competing for a contract to replace the U.S. Air Force's KC-135 Tanker fleet. It has offered the KC-767 Advanced Tanker, and a decision is expected in the first quarter of 2008. Transferring fuel through a boom, via the remote vision system during nighttime conditions, will significantly reduce risk for future tanker customers like the U.S. Air Force.

premier ravitaillement du F 15 par un kc 767 de nuit

KC-30 Tanker Designed to Meet or Exceed Key Performance Parameters

La perte du contrat des ravitailleurs US signifirait la mort de la branche militaire de boeing (après les echecs du yf-23 et du yf-32)

C'est réglé, je devrais plus rien poster tard la nuit moi.

la mort de la branche militaire d'airbus (après les echecs du yf-23 et du yf-32)

J'savais pas qu'Airbus avait conçu et construit le YF-23. Et je connais pas de YF-32. Le X-32 éventuellement.

C'est parce que tu penses avec la calculette Clansman au lieu de penser avec le cerveau.
