they're STILL testing stuff, almost 4,5 years after first flight? What on earth is holding up this project?
J-10B priority drops. I will rank J-15/J-15S and J-16 even more important than J-10B. There are plenty of aviation project going on in China. China need to prioritise their project if it wants to move on fast.
I believe J-10B is being sacrifaced and more resources are devoted to other projects.
