The F15C never went up against a real air threat. It may not have faired so well against soviet Flankers. Then things would have been much more equal. And the F22 was conceved when the russians were working on 5th gen platforms, they have started working on them again allthough they are a very long way from being operational and even when they are will probably not be as capable as US 5th gen platforms. look up PAK FA. F16 block 60's wouldn't fair to well against these threats. And IMO an F22 is worth more than 2 F16 block 60's in A2A combat, so is the F35.
Are you shure an F22 will ever get shot down????? No F15 has ever been. So i wouldn't be talking about that in absolut's.
Reason why no F-15 have been shot down is because, USAF never have properly battled a well armed well trained adversary before. Of course I wouldnt say F-16 Block 60 could defeat F-22 please read people post carefully before posting your own to comment about others.
Never stated anything about a2a combat with F-16 vs F-22, dont know where you got that from my post.
Yes I am sure that eventually an F-22 will get shot down, its good but not that good that it cant be shot down.
USAF hasnt in modern times battled an equally adversary yet that is why USAF have had such a good record. Match an F-15 with an Su-30 with a well trained pilot and you will have your first F-15 possibly downed.
Nothing is invicible you better remember that, as US once removed the guns off fighter jets an replaced them with missles cause they thought that missles made them invicible and untouchable but that was a huge mistake when missles failed and they were confronted in dog fights without there guns on the fighter jets.
