The way my underinformed a$$ sees the newly discovered production rates of certain warplanes for the PLAAF and PLANAF, generally it does provide a generally good insight on how the PLAAF and PLAN lineups would look like, going into the coming decade or two at least, IMO.
Do note that only offensive-purpose warplanes (i.e. fighters and bombers) for the PLA are included. Non-offensive-purpose warplanes (i.e. AWACS, ELINT, reconnaisance, tankers, transport aircrafts etc) for the PLA would not be included.
1. The J-20s and J-16s (alongside Su-35s) would become the mainstay and major fighting arm of the PLA for the coming decades.
2. The J-11s would be gradually phased out and replaced by the J-20s (at least from older units), alongside those imported Su-27s and older Su-30s.
3. The J-10s would remain as the mainstay and support fighting arm of the PLA for the coming decades.
4. The J-15s would remain as the mainstay of the PLAN until the J-35s has been introduced into mass production, of which the J-15s would be gradually supplemented and then replaced by the J-35s.
5. The JH-7s would be gradually phased out and replaced by the J-16s.
6. The H-6 would remain in service with the PLAAF for considerable periods of time until the H-20s have been introduced into mass production, of which the H-6s would be gradually supplemented and then replaced by the H-20s.
However, there are two warplane models which I am still unclear with.
7. One would be the J-31, which is basically the land-based version of the J-35 multirole fighter. Would the J-31s be introduced to PLAAF service to serve alongside the J-20s as China's 2nd land-based 5th generation fighter, or would it only be meant for export? Should the earlier option be chosen, the J-31s could be the ones that would be gradually supplement and then replace J-10s (at least from older units).
8. Two would be the JH-XX, which is an even less well-known fighter-bomber project compared to the H-20. No confirmation exists on whether the JH-XX project is even real at this point. However, if the project does exist and become a viable fighting component for the PLA, then the JH-XXs would be a complementary component to the H-20s.
