an you're included in that, @undertakerwwefan
most of the world renounce experts think that they are all Fits in 4.5th/4++ gen jets with the exception of F-22/F-35/J-20/J-31/Su-57 which are in separate gen 5th class and you're neglecting those world renounce experts, your self proclaimed expert listing/count worth nothing in the front of those world renounce experts "WHO SAID THAT THOSE FIGHTER JET ARE NOT IN 5TH GEN CLASS BUT IN 4.5TH/4++ GEN CLASS" and you're not expert @undertakerwwefan

But not designed from scratch @undertakerwwefan don't have stealth features, supercrusie, short take off and landing characteristic etc etc @undertakerwwefan
your definition are wrong, the whole world is not consider those jet as 5th gen jets but 4.5th/4++ gen, only you think that is not worth of talking you're wasting PDF precious bandwith @undertakerwwefan
