why indians were kept off limits? no one was to bee seen in the picture?
However at this moment PAK-FA specs. are not known. Just flying a frame influenced from JF-17 blk2 does not tell that it could beat JF-17 in itzs present form. PAK-FA is still at prototype1 phase while JF-17 is fully integrated into PAF and has been tested against F-16.
In any case the major difference between JF-17 and PAK-FA will remain that former was custome built for PAF requirements, where as later is not build specifically for InAF.
I can only laugh after reading your post. Custom built? SU 30 mki this is what you call custom built, India wanted a 2 seater, they got it, India wanted Israel avionics, got it, India wanted french systems as well, again got it. Thats what you call custom built.
JF 17 has nothing so far. You have not much choice whatsoever in choosing the engine. Avionics are chinese and will remain as such, What customisation was done on it?
Regarding PAK FA..... India will modify it as it wants it to be, FGFA a 2 seater, India will even develop avionics and some other systems I can't recall right now, But easily available. Please read or provide a link before posting thrash.
