KYli said:F22 is the best air superior fighter in US stockpile, I doubt US is willing to sell this state of art weapon anytime soon. Maybe 10-20 years later, but definite not anytime soon.
One of the reasons a decision must be made soon (next 2-3 yrs.) on a foreign sale fo the F-22 is because production is currently only scheduled to continue through 2008, and might be extended through 2010 until F-35 production ramps up. Once that production line is down, probably the only thing that could open it up again is a full scale war with for example China (of course I don't think that will happen). This is why in 10-20 yrs. it is 95% certain nobody will be buying F-22s, not even USAF. If Japan wants it and the US wants to sell it, we will know at the latest by the end of 2008.
