What ever happened to the Y9 project, it was meant to be the most advanced cargo plane project in China, to challenge capability of the C130J
Supposedly it has had its first flight sometime last year, but we've not heard much since. I think they're trying to pump out for Y-8 GX and AEW aircraft first.
they have been saying that China has solved engine issues 5 years ago but still AC313 uses foreign engine, J10B still uses AL31, ARJ21 uses foreign engine and even Chinas new C919 civilian aircraft is going to use foreign engines
the engine seems to be Chinas achilles heel big time, even although they have thrown all resources at this problem for last 10 years
China must master engine technology
To be fair all recent J-11B is using WS-10. Progress is being made.
