Most Chinese aviation fans don't like Shenyang. They won most of their contract thru powerful connection. While CAC get the contract mostly because it delivers and meet expectation. WS-10 indigenous delay is also because of Shenyang. J-10B received WS-10 engine that late might be also do with rivalry of CAC and Shenyang.Unfortunately, I sense some of the usual bias against SAC in some of the posts here. Claims are that this SAC J-XX will meet more of the basic 4S requirements than F35, T50.
Such a plane will have a big role in PLAAF.
