The SU-37 would require an absolute master, a 20+ year, highly experienced flight test veteran to beat a regular USAF GI in a F22.
Plain and simple.
Ever seen russian workmanship "up close"?
Airframe construction is frightening with those folks......
Im guessing that in a short but EXPLOSIVE war, it would cost 10 SU37s for each F22.
Problem is you could buy 12 SU-37s for each F22.
Go figure....................... ....
