Well the currently flying aircraft should definitely be called "prototypes" because "initial production batch aircraft" is for after the development is finished, the design is finalized, and the aircraft is being produced for induction in the PLAAF, not for testing. The J-36 is clearly in its development phase not in its initial production phase.
I am not sure what you are trying to say here. There could indeed be more than 1 flying prototype but are you suggesting that there are multiple different flying prototypes simultaneously given the same serial number? This seems highly unlikely, what is the benefit of doing this? Not only is this needlessly confusing for the people working on the plane but it is unnecessary. Serial numbers are just a number, why would they do this?
I have no idea what you are trying to say here. I believe IOC means "Initial Operational Capability" which is achieved after development is completed and the aircraft is being produced for actual PLAAF service. Perhaps you mean something different with IOC? Also again "initial production batch aircraft" are the first aircraft that are produced after development is complete and they are intended for actual PLAAF service.
Maybe you are misunderstanding or being overly optimistic about the timeline. The J-36 is not ready right now and it's not even close. If you think the first production J-36 for PLAAF front line use will come in 2025 you are way off on the timeline. We are not even close to that point it will take years more of development.
Maybe you didn’t read what was discussed before. Most of this describes what happened during the development of J20.
Daubed the number, they did; yes, PLA and Chengdu did not explain the reason for the daub to anyone.
Initial production batch: The J20s sent to Dingxin Base and Yanliang Base are considered "initial production batches". Their numbers are completely inconsistent and are considered to be in service. However, the aerodynamic shape, DSI inlet shape, tail wing, etc. of these 10-20 J20s have undergone various changes. They are different from the official equipment version J20 we observed later.
So it is necessary, I would think "
The "prototype" does not completely determine the production model (IOC). It may be the "initial production batch" that determines the production model (IOC), and the "initial production batch" can also be considered a part of the "prototype" of the J20.
J36 currently only has one serial number: 36011. I would not consider him mature. Again, all test flight photos are blurry. And based on the number of flights announced in recent days, it’s hard to believe that this is an orphan.
