ce qui est vraiment intéressant:
"The aircraft's ability to maintain supersonic flight without afterburners has surpassed its design specifications, say air force officials. [b]While the aircraft is required to dash supersonically at M1.5 without them, which the air force dubs "supercruising", the F-22A has demonstrated this at speeds up to M1.68, they say. The aircraft can fly faster than M2.0 with afterburners.[/b]"

"Raptor development has cost to date roughly USD30 billion. About USD15 billion has also been spent on aircraft production.[b] The aircraft's current per-unit cost, including engines, spares and support equipment, hovers between USD120 million and USD130 million[/b], according to Lockheed Martin.The company is currently producing Raptors at a rate of two per month."[/quote]
