p2prada, what open source are you talking about? How exactly ahead of PLAAF is IAF?
You are overestimating the ability of your arsenal which you built back in the 1990s, yes they made a strong IAF then, that is why I admitted IAF had advantage. But now as China is gaining the capablity of building indigenous planes, India is simply losing it.
Let me give you a hint, the best planes in IAF are still Russia-built, but now China stops importing Russian toys. It is not that Russia refuses to deal with China, instead it is China is getting disenchanted. Buying Russian planes is always an available option, but PLAAF shows no sign of going for that, meaning they believe Russian planes are not worth it.
Chinese defence industry is far ahead of their Indian counterpart, just look at the inventory of both sides, 90% of Indian weapons are imported, whereas 90% of Chinese weapons are domestically manufactured. The reason we are stoping buying Russian airfighters and refused a proposal by Russians to joint-develop a 5G plane is because we are capable of building our own.
In my opinion, Rafale or Typhoon , it is just the last straw for India, which will not change the fate of IAF being left behind in the long turn. As long as India is relying on foreign weapons, China has an upper-hand in this race.
Let me reiterated what has been said again and again by Chinese policy-makers, military modernization is not something you can buy with money.
Military modernization is something you buy with money. Your policy makers are feeding BS to your population. Look at Pakistan today. They cannot buy anything worth talking about and also look at their current situation. Kashmir was as bad or worse and we handled it quite well in the same duration of time. In our condition the terrorists had a safe haven in Pak. The Taliban has no such safe haven, they are fighting the Pak Army on Pak's home ground and the US in Afghanistan and still winning. All this because they are broke.
Without money there is no military, you may as well use bows and arrows. So, stop listening to your policy makers with what they feed to your population. Get outside, forums are a great place to be, and see for yourself. See how UK is at the brink simply because they lost one lousy deal. European militaries have completely lost all the glory of their former selves because of lack of money.
Without engines and electronics your defence industry is at the same state ours is in. Your radar system is not even worth inducting in the IAF, maybe only as MLU for old aircraft. The KLJ-10 today is at a similar level as the RDY-2 in 1997. Your engines are all imported from Russia and everybody knows the AL-31F series are all junk by today's standards. Everybody is moving up the chain. China is not.
The best planes built in Russia are easily some of the best aircraft available. You are still trying to achieve MKIs standards, something Russia did in 1996. MKI is obsolete if you compare the current MRCA fighters and the current MRCA fighters are obsolete compared to the Super MKI. I have spoken to both American and British airmen. Both rated the Flanker to be at par or higher than their own fighters, and this was when we discussed the Su-35, not MKI.
As long as India imports, overwhelming technological superiority is guaranteed. China does not have this advantage. Don't you see the difference? India has an economy that is 4 times smaller than China, but we are able to maintain a technological lead over China and our numbers are pretty good too.
In 10 years you may have your fifth gen flying, at the same time we will have one too. We aren't discussing the differences between our military industrial complexes, we are discussing direct difference in technology between our two armed forces. Even in that case, you built your first SSBN in the 80s, but even today none of the SSBNs have left Chinese shores. At the same time, our very first SSBN is going out for deterrence patrol by this year end.
Imports and foreign JVs are helping us maintain a technological superiority as well as a minimum numerical parity against an economy much larger that our own.
The reason you are no longer buying Russian aircraft is because you have everything they already have. It is the same reason why the Su-35 was rejected by IAF too. We already have what they have. There is really no reason in buying something so similar. It's like forcing all the Hornet clients to buy Super Hornets, nobody will do it.
