The word 'poor' implies a comparison.
The F-16 will lose against the F-22, so does that mean the F-16 is a 'poor' air-air fighter ?
This is real physics, not 'Bangladeshi physics'. You want to have custom physics, talk to the Chinese and the Iranians.
And how many of them are there in deployment ? Please do not bring up the Chinese or the Russians.
No, you are not. The gullible may believe you, but not I.
The vast majority of the world's countries have to import their defense. That means they have to accept what the market have. The Russians are unlikely to product a viable '5th-gen' combat aircraft and the Chinese are somewhat 10 yrs away. In the mean time, the F-35 is the only game in town.
F-35 will be around for decades and there will be air-combat optimised 5th generation fighters from many countries around during this time.
Just how will be F-35 stand up to these fighters that will be stealthier, supercruise and be more manuverable?
Will the US then allow export of the F-22 to certain allies like UK and Japan?
