The old style radars are like a flashlight in a dark room. They can be detected long before target returns can be seen.
One of these against an F-22 is like a man with a flashlight fighting a man with night vision goggles. That was the whole idea of the F-22. Don't fight fair.
I talked to a pilot who went up against an F22 (he was in a F16 as I recall) and I asked him how he fared.
He said: “I was a baby seal.”
Give MiG a break. They are great for what they were designed for, shooting up civilians and lightly armed militias.
As far as real combat, we need to look no further than their test in real combat. They were either shot down or ran like scalded dogs to some foreign hiding place.
