I assume the fact that the PLAN has yet to put WS-10A mounted J-15s on Liaoning shows how careful they are in minimizing the chance of accidents. However, I guess soon (within this year) the the PLAN would have to test WS-10A mounted J-15 (B)s on Liaoning and make sure they work, or else there's only limited supply of AL-31s.With WS-10s to boot!
i think it's old photos.
