J-11 China Figter Similar To The Sukhoi Su-27 Russian
J-11 China Fighter Russian Sukhoi SU-27 Similiar
This isn't copy, this is a big improvement. Yes first we copied we bought a whole production line to produce Su27 but later we found out that we have so many stuffs are better than what the Russian selling to us. Why do we need to copy? We put our own new radars, engines, electronic systems and weapon systems in it but we keep the Su27's frame because it has the best frame for a good fighter, now J11B is a good fighter can counter Su35, F15SE and F35, good job China.
