But they still need another 24 x J15B or batch 3
CV-16 trains the pilots
And CV-17 to maintain those skills
5th generation is not going to be ready that soon
Bad to wait for 5th generation
They need fighters
A lot of things are not making sense.
Building carriers with no naval trainers in the pipeline.
Hardly enough J-15s to fill CV-16 let alone CV-17.
Nothing specific about J-15 replacement except for rumours.
Oh, I think they will fire up the J-15 batch production for another 24 J-15 at least, I see little logic in truncating J-15 production at 30 birds, but there could well be anotherr bird in the pipeline?
Without doubt PLAN will produce more but that is the mystery. Why isn't it happening? J-15 is also by default acting as trainer because there is no navalized trainer. So no birds for CV-17.
Pretty sure that the navalized JL-8 is fulfilling the trainer role. That is evident from the documentary I linked which directly states that it is being used train naval aviation fighters.
My theory is that they are waiting to re-engine and upgrade avionics for the next batch of J-15s. Current ones are still using Russian engines and slotted array radars.
