100 a year is really not all that many, and if there actually is a shift to the WS-15 incoming, iirc the rumors were that production rate was likely to drop temporarily. And the emphasis on new production methods is something that has been emphasized about the J-35 since the FC-31 days.J-20 is also easy to mass produce and we know that because production rate has already reached 100 a year. And it's likely they are still expanding its production.
Sorry, but until we see one of the CCAs actually flying, and get some idea of how they are supposed to be integrated into the PLAAF I will assume that they are a less mature program than the J-35, which has several flying examples and is rumored to have already been delivered to a unit for testing. CCA is also the name of an American program, we don't have any idea of what the PLAAF intend with its UCAV programs, so equivocating them doesn't make any sense to me.We also do know that CCAs will have to be a larger % of PLAAF going forward.
I don't necessarily believe that the land based version is actually going to reach some arbitrary goal of 1000 units, but assuming that its some sort of stop gap or half-measure seems premature.
