Lol so now it is a Chinese knockoff? First you claim the J-20 is dedicated for a strike row, then you claim it is unstealthy, and now you are saying its a Chinese knockoff? Why are you introducing a bunch of red herrings? Why don't you defend what you said earlier about it being a strike fighter? Also if you know what a luneberg lens is then isn't its detection inevitable?
yaa I again repeat the amalgamation of Mig 1.44 russian abandoned project and stolen F-35 documents chinese came up with a poor stealth knock-off with no engine to match its intended purpose of striking US navy in pacific...
Chinese desperately waiting for russians to provide them some knowhow to thr new engines which russians are still working with but without any success...
and again for the hundredth time
Radar detection is one thing
And Infrared detection is completely another thing
