I’ve moved our discussion on the Su-57 to here.
I admit that I was one of those who didn’t think China should buy the Su-35. Apparently, the PLAAF thought otherwise. I also highly doubted that China had bought them because of all the crying wolf from the Russians. Apparently I was wrong.
Please note that my objection has never been about the quality of the Su-35. I have insisted from the beginning that the Su-35 is an awesome fighter plane, one of the best. I have never questioned that. My objection of the purchase is purely from a strategic standpoint. I have always felt that China should go through the growing pain. No matter how painful it is, China needs to throw away their crutches. China needs to become independent in their weapons development programs.
And here I come again with my own uneducated opinion. The Russians asked China to join them in the development of the Su-57. But China declined. If the Chinese were truly interested in the Su-57, they would have agreed, especially when it was requested by the Russians. That was way before the J-20 came out. If the J-20 has not gone smoothly, the Chinese might also be convinced to join the Su-57 development. As far as we can tell, the J-20 is going very smoothly. There is even less incentive for the Chinese to join / buy the Su-57 at this point.
China bought only 24 Su-35’s. That suggests to me that the Chinese wanted the Su-35 for its technology, not the actual planes for use. As someone mentioned yesterday, it could be the fly control software. It sounds logical to me.
And let’s look at what’s new on the Su-57. Stealth shape? China’s own J-20 and the J-31 both have stealth shape that is, at least, as good as the Su-57. In my own opinion, the J-20 and the J-31 are both completely new designs that incorporate pure stealth tech. The Su-57, on the other hand, is a Flanker derivative.
The Su-57 have TVC. The Su-35 has them too. And China has obtained copies of the Su-35 along with its awesome engines for a while now. No need to get the Su-57 again.
Other aspects? In my own opinion, China is ahead of the Russians. And the Chinese have been ahead for a while. My own opinion.
