Yeah , and the Beijing has been doing both for decades , enlightened , are you ?
Else , what is J 20 and their AWACS ?
I am not saying that it is a wrong thing but declaring yourself superior using other's technology and claiming that you build it indigenous sure is ! Your scientists proudly do it all the time !
... Who declared them top class ? I can say the same for China's defense equipment ... What difference does it make ?
What makes you so sure these are the same as the 60 years Soviet bombers and haven't been innovation/improved upon ? As for the old carrier , you know how long have you been bearing the burden of a 1953 British commissioned carrier !
... How old is the highly overpriced Admiral Gorshkov ( according to Wiki , it was laid down in 1978 ) ?
... Are you accepting them both as rusting crap ?
China bought that for gaining experience and now they are proudly improving its design and building a indigenous one ... SO ?
Learn to debate with civility ... I know its difficult when constantly being refuted but still ...
They took 30 years to make something which is constantly being rejected by your AF , let alone any foreign one ! Seriously , was this the longest period of time taken to develop a military hardware ? You have had JV's and have been building license building aircraft so long ... Why couldn't you develop a new one based on that experience ?
...
Both things are different ... Things are customized as per customer requirements not being improved/design changed ...
Not really , you showed us who was trolling you declared a PT to be superior than operational aircraft ! We know who constantly loves to troll and flame on China defense threads as your lot began here ... Just check from the start of the thread ... This , thinking is getting you nowhere ... China's still way ahead and self reliant !
