Come on guys... too much trolling now.
Rafale IS a very good fighter and the best weapon it will have is Meteor missile and MBDA stuffs. China also will have long range and ramjet missiles. PL-15 has over 200km range and dual pulse rocket engine to improve terminal energy and kill probability with improving datalinks and active radar. The fighter can shoot and run but much better than previous PL-12 versions.
PL-21 and PL-XX will have longer range and at least one of them is ramjet powered. So basically similar capability. Rafale using SPECTRA did not work in NATO tests reportedly but who really knows? I think US did exercise with French against some old previous soviet nation's S-300 and already ESA types of radar can easily defeat SPECTRA. Very useful against older style equipment but already not that useful. When 10 years pass, will be even less useful unless they find new ways to improve it.
While Rafale may be very good, there's no way the air chief can know exactly how it will do against J-10B, J-10C, Su-35, J-16, and J-20. Not today and not what these fighters and other AWACs and SAM digital equipment can handle tomorrow or 10 years later. So this statement can be believed only by those who really want to but reasonable non-Indian person will know this is a bit rich of a statement to make. Maybe this guy does have very very detailed information about PLAAF fighters but now he say it, it's like admiting he has super top secret info. More likely just saying this for morale boost and boost Rafale advertising to make people accept Rafale fighter easier. Otherwise maybe people will think Rafale is too expensive or something but if people believe 36 - 100 Rafale is silver bullet to kill all of PLAAF, it is easier to spend big money on it. China will remain quiet on this and just observe. State media will not issue statement saying whether PLAAF can handle Rafale. We know nobody can or want to fight real war. Only talk about it and feel good about themselves. But honestly, I really doubt PLAAF worrying about Rafale and only a few squadrons. By time IAF gets all their Rafales, there will be hundreds of F-35s in USA and Japanese bases and ships just to China's east. That's a real worry.
