The F-22 is far from a "replacement".
The SR-71 has been replaced by the Aurora. It's a pulsejet running on methane, and goes faster and higher. I think the only reason it's not in active service right now is because of the refueling issue. Methane is exotic in comparison to JP-5 or JP-8 -- which can both be pumped from the same equipment. A specialized XKC-135 would have to be outfitted, and that thing would probably have to have it's own internal refrigeration system.

Quite the opposite - the B-2 has an even 'smaller radar sig' that the F-117!
