I suppose Boeing implies that the USAF asked for the most expensive option so they got justification to bury the F-15 and save funds for the F-35.
Yet they are used in Libya...
IIRC they also said the stealth advantage would only last them 5-10 years. One of the reasons they insisted on being able to add their own electronic equipment upgrades, i suppose.
They also forgot IRST.
That can be said of quite a few peoples.
