This is just unnecessary obfuscation. Whether the designation of "A" and "B" are official is COMPLETELY irrelevant. The A version is the one under contract that China is legally able to license produce. The B iteration is the "indigenous" version which uses the stolen intellectual property of the Sukhoi company to manufacture a modified aircraft that is more suited to PLAAF's current requirements. That you are even arguing about this is simply astonishing to me.
And you would know this because you saw the original contract?
If not, kindly stop trying to pass off your own opinion as fact.
The fact is that the licensing agreement has always stated that there would be an ever increasing share of Chinese made components used in the aircraft, and the Russians never had any problem with that until the J11B came out.
"The breakthrough in engine manufacturing technology allowed China to increase its share of domestically developed components and technologies from 70-75% to over 90%," the newspaper cited an official from the Russian state-controlled arms exporter, Rosoboronexport, as saying."
The use of demostically made parts will begin after the first 60 are assembled using Russian kits and eventually 60-70% of the parts will be manufactured in China
That means the original license agreement allowed China to add their own domestically made components onto the Russian designed airframe so there is blatantly no breach of the original contract.
The only reason the Russians are trying to make a problem now is because of they fear that the J11B is superior to their own latest flanker derivative and so might take their diminishing share of the world fighter market were it ever offered for sale. But since China has neither exceeded the original contracted production numbers nor offered any J11 version for export, China has done nothing wrong.
What does the fact that the J-11A contract wasn't finished have anything to do with anything? Again, this is just noise rather than signal. If China didn't want to build all 200 J-11A's, that's its own business.
Again you make guesses and assumptions and pass them off as fact.
China signed a license agreement with Russia that allows China to manufacture 200 Su27 airframes with increasing Chinese components as I have already established. The deal was for the airframes and never included engines or radar as Russia did not allow those technologies to be transfered. Thus China continuing to manufacture the airframes when the original contracted number has not been reached is in no way a breach. And since the original contract clearly allowed Chinese components to be used in the J11s, putting Chinese made engines and radars on the airframes is no breach either.
What's NOT its business is to then take the intellectual property of Sukhoi, modify it without permission, and make several hundred more aircraft.
And you are resorting to down right lies here.
Where are these 'several hundred more aircraft' you claim China has made?
The Israeli F-15 example is completely irrelevant. The Israelis are not building additional F-15's, modified or not. The Chinese ARE building modified Su-27's in the form of the J-11B. Just because you add your own components doesn't mean you somehow acquire the right to use the Sukhoi design, tweak it, and then call it your own.
SAC is still building J11s because they still hold the license to build more. Its in their contract and perfectly legal for them to continue to do so until the 200 units limit has been reached.
And since when has China ever claimed that the J11 was Chinese designed? More lies.
So according to you as long as the sum total of J-11A's + J-11B's = 200 or less, China is legit? What's the likelihood of J-11B production being less than 200? Probably zero. There are already probably that many J-11B's in service, being certified, or on the production lines, with many more to come, to speak nothing of J-11A's that have been flying around for years.
And you of course have proof that there are 'already more the 200 J11s'?
China stole Russian intellectual property.
Keep repeating something will never make it true.
China purchase the production license to the Su27 airframe so there was nothing 'stolen'. The fact that all this BS is about China putting in completely indigenous components makes it ever more ridiculous that anyone can claim that China is violating Russian IP.
Russia never had a problem with China making Su27s using knock down kits while gradually increasing the percentage of components made in China. They even sent people over to help teach SAC how to make some of the components. That was fine, but as soon as China puts in Chinese designed engines and radar onto the airframe it becomes a violation of IP? Do you even understand what the concept of IP is? As your argument has it entirely backwards.
Duplicating Russian tech without permission is violation of IP. Replacing Russian made components with entirely indigenously designed ones is not. At the very most the Russians can claim that such unauthorized mods would void any warranty. But that's hardly a violation of IP.
