It seems J-11B, J-11BS,J-15 and J-16 have a much faster pace of production and development than J-10B... The only solution Chengdu do is to pump out J-10A and J-10S. Isn't Chengdu suppose to be more capable than Shenyang?
Seems? We simply don't have enough accurate info to judge.
When did all of these programmes start? What level of complexity was involved in terms of how much of an improvement these planes are over their predecessors? What stage of testing and development are they at at this precise point in time?
The J11B is not anywhere close to as radical redesign of the J11A as the J10B is of the J10A, the J11BS is just a twin seat J11B as far as anyone can say, the J16 is a twin seat J11B with enhanced ground attack capabilities and probably many of the airframe enhancements found on the MKK. The J15 is very much based on the Su33 prototype SAC got from Ukraine.
Since the J11B is using pretty much the same airframe, and most of the changes with the exception of the engines are internal, it should have required far less test flying than a major airframe mod like the J10B. The J15 and J16 programmes also benefitted greatly from the Su33 and MKK whereas the J10B had no such help. Even if it took longer, that is perfectly within reason.
But as I said, do we even know when all the programmes started and ended to make the case that J11B, J11BS, J15 and J16 were developed faster than the J10B? All we have are observations, rumors and guesses, based on landmarks of first flight, test flights, more prototypes and finally serial and then full scale production, and with the exception of the J11B and maybe the J11BS, none of the others are in full scale production yet.
Of the J15 and J16, are we only seeing prototypes, pre-production birds, small scale production examples or full scale production versions? We don't know. Will they even go through all those different phases? Will the J10B?
