This is the last time I am telling you that it was carrying Lundberg lense is your wishfull thinking and nothing else. Why China bought Su 35 inspite of having so called 5th generation fighter. You answer me.
My most important point is that India's air chief and air marshal has said catagorically that J 20 is not a threat for India. Parheps they are not as knowledgeable as you are. Even China has accepted that Tejas has stealth features and Tejas is a plane of future. In its comparison article of Jf 17 and Tejas, Chinese media had concluded the article by saying that Jf17 is a plane of present but Tejas is a plane of future. Do not argue by making your assumptions a base. Give the reference in support of your argument.
The Theory of a Lunberg lens is not some kind of wishful thinking my friend! It's a reality! I have not Said that I don't believe that IAF didn't detect it.
No country will fly their 5 generation jet without Luneburg lens in patrol duty during peace time. So, the so called "Su-30 can detect J-20" is meaningless. During war time, J-20 RCS will be completely different.
Recently, US claims that their F-35 has met Chinese J-20 in the air outside Chinese border. Did you see either side bragging "Our jet radar can detect their stealth jet"? No, because both sides knew both jets have Luneburg lens on board.
Now coming to China buying 4th generation fighter even when it has 5th generation option like J-20. Have you even bothered to read the Discusssion?
Is it about China Buying SU-35 when China has 5th generation J-20? That logic is so flawed. If we go by this logic than we can also say that the F-35 is is not so Advanced and Hence US Airforce is buying more F-15EX. Read These sources:-
You see mate, you can't always Operate 5th Generation Aircrafts in large numbers because it's very expensive in doing so and hence you also need 4th Generation Aircrafts to supplement and build up a bulk of your fleet using them. Also there were several other reasons for China buying these SU-35 Flankers from Russia.
Also China wanted engine Technology from it possibly too.
You really think that Chinese are so dumb that they will build a jet like a J-20 which supposively is to Match F-22/F-35s be detected by a PESA radar from 300 kms away?
I have already answered all your questions in the Past and also with regards China buying 4th generation, please read the entire thread 1st because you have clearly not done so.
I am argueing with giving references here. Also in my previous posts in this thread I had also posted pictures of F-35 and F-22 Carrying radar reflectors also.
So whatever has been told by me is nothing with regards to wishful thinking.
