In a "high-end fight", what's the anticipated loss rate? And how fast can the lost ones be replaced?
This is conditional based on a production line being restarted.
In a hypothetical scenario, an opposing country (Russia or otherwise) would probably be throwing Su-35s and T-50s at the F-22. I believe both would struggle at BVR engagements when it comes to spotting the Raptor. the Su-35 is a blimp on radar, and the T-50 maybe the size of a T-80 given those massive engines.
