I read a journal that remarked that "the F-22, with its stealth, speed and high altitude capability- is the only platform consistiently able to defeat 4th generation SAM's."
Look, its no secret that the USAF wants a very high altitude cap. for bombing purposes. The F-22 will fill that role.
Imagine, radar sig. of a f-117, speed of a sr-71, comming at you at 80k- it will be better that the la-7.
