The problem about mil hardware, is not like the good old days when a P51 was a P51 was a P51.
We have to much proprietary avionics stuff on American birds, a Belgian F16 might not do as well, or maybe better than his American counterpart in the same block F16.
Eurofighter Typhoon and Rafale (not sure if that’s a 4th gen though)has sex appeal for sure. Somewhere deep down I have a pic of some lost Brits in Erbil. Probably had tanking issues and needed a splash of the ground based F24.
Now this, is the opinion of a guy who has never flown a fighter, but may know a thing or two about capabilities, maybe.
