You only pick on a single arguement and try paint all others as disappointment? Yes, our engine is still the bottleneck and I dare to say its the only one in China military hardware. Are you going to deny China advancement in UAV which is through our research? In terms of missile development. China and US are the both only reported countries to have develop workable ABM with mid course interception. Not to mention, our ever advancing Ship buidling. You claimed all this as money wasted?
This is where your argument hits a road block. On one hand you are pounding your chest claiming Chinese superiority in weapons and research/science yet now you are conceding the fact that China is behind in engine technology.
Engine technology is arguable the most difficult technology to master because of the various fields involved which includes metallurgy, advanced allows, crystal blade technology, electronic, engineering, manufacture, and many other fields which includes innovation. So if China is so much more advanced in technology and research as you claim then why after so many years is Chinese engine development lagging even though the Chinese have foreign engines to copy?
That is why I give another 5 years timeline for China to beat any of your Russian hardware in terms of advancement once WS-15 deput.
More chest thumping, for that to happen Russian engineers would have to Cease all development, which isn't happening since development has never stopped and in fact Russia is working on new generation technology such as a mid course missile with MIRV capability giving it an ability to engage 10 targets, sorry China has no equivalent.
As for your PL-12 is just a internet myth like to pick up by anti China western basher. The fact, PL-12 aerodyanmic never even resemble the R-77 bought from Russian speaks on itself. Why would China pick and use an electronic component which she already deemd inferior?
I have sources to back my claim, do you? Any Source or person that claims something that is not to your liking is automatically anti China and a lie, in any case prove that the PL-12 does not use those Russian electronics.
as for your so called accusing of so much copying. I can sense the desperation and helpless of Russian being lag behind in China.
No China does not copy at all the J-11, J-15, and J-11bs are totally original. The Russians are totally lagging behind with all the Russian input we still see in Chinese designs be it L-15, Phazatron and NIIP providing assistance to China to built their own radars, or the recent revilation about the WZ-10 helicopter which was disclosed not only by the chief designer of Kamov but years ago by a Kamov employee on a Chinese forum.
The list of Russian involvement in the Chinese defense industry goes on, of course People like you are in denial.
As for J-20, Mig already outright denied any assist to China. So may I know its copy from what?
Did I ever mention copying or Mig? The chief designer of the J-20 in an interview revealed that Russian engineers are working on the J-20 and before you go ape sh!t and accuse the Russian media of lying the article was posted on this forum and if I recall correctly a Chinese member posted it and it was in Chinese.
By Accusing China as only know copying is a way to ease your pain of losing to mighty CHina in near future. I can understand your exasperation. So pain that your mother land fall from grace. Any rational being will also turn into a jealous and petty monster given in your case.
Keep pounding your little feminine Chest at the end of the day you got nothing to support your claims. You, just like may others like you have an inferiority complex. Dragons are not real much like your claims, but bears are.
