This man has a point, exaggerated but true for some aspects. Real life Su-27 and R-27R-ER-T-ET probably worse than we know and only thing we have against F-15s is Mig-29 with cucumber like radar, low ferry range and low payload(Damn even she doesnt have the ability of tracking 2 targets simultaneously). As for Su-33, a cheap imitation of Su-27 and playing with these planes become like bed fantasies. But, hey dont worry Flanker and Fulcrum lovers we can still get drop on them with creeping between mountains, except if they didn't add ground penetrating, AESA radar for F-15C :)
