[quote="MoX"]Pour le cout du B-2, j'ai toujours entendu [b]2[/b],2 milliards de dollars.
Mais depuis le crash sur Guam, tous les médias annoncent en coeur 1,2 milliards.
Le premier communiqué devait être donc malencontreusement erroné. ( ? )

(Et, n'oublions pas, 2,2 milliards de $, $ des années 80 ! ! ! ! )[/quote]
Euh, non!

[quote]The cost of the B-2 program in 1994 dollars was reported at $737 million per plane; however, the total cost of the program with development, spares, and facilities averaged over $2.1 billion per plane as of 1997 according to the B-2 program office.[/quote]

[quote]Northrop made a proposal to the USAF in the late 1990s to build additional aircraft for ~$550M each. This more accurately reflects the per aircraft cost if the full order had been manufactured. The high development costs included: another stealth prototype (now at the USAF museum), security costs which included inefficiencies of separating design teams, the development of a computer aided design system which requires no paper (it was the first aircraft so designed), a totally computerized manufacturing control system (the first of its kind), and a computerized maintenance system to help crew chiefs with the most complex aircraft yet made[/quote]

Beaucoup de gens oublient que les EU comptent souvent le-tout-compris pas comme la France qui calculs avec le prix fly-away.
Par exemple, le prix fly-away du F-22 n'est "que" de $100-140M contre €49M (donc un peut prets $70M) pour le Rafale! Je trouve la différence très minime.


Pour le Raptor:
[quote]But the reality is, if the Air Force wanted to buy just one more jet, it would cost the taxpayer less than half that amount. The current cost for a single copy of an F-22 stands at about $137 million. And that number has dropped by 23 percent since Lot 3 procurement, General Lewis said. [/quote]

[quote]The average unit flyaway cost for the F/A-22 in 2003 was about $178 million, while the unit flyaway costs for future annual buys were projected before the budget decision to decrease to $127 million, $111 million, and $108 million in fiscal years 2007, 2008, and 2009 respectively [that is to say, roughly double the unit flyaway costs of the single engine F-35]. [/quote] [seulement si plus de F-22 seront produit, ce qui me semble raisonable]

Pour le Rafale:
[quote]The unit flyaway price as of [b]2000 [/b]is €47 million for the Air Force version, and €49 million for the Navy version.[/quote]
