Probably after a year later , you will see J-16 enter service and see j-10b 1040. J-10B will be a testbed.I hope wwe won't enter again that discussion.
IMO it was - even if I'm too a bit disappointed - not surprising. 1038 - if confirmed - would be a pre-serial block aircraft and as such one which will most likely be assigned to the FTTC / a test regiment ... right the same procedure as with the J-10A and most likely with the - in Your eyes so much better - J-16, which is only available so far in prototype form too.
Like I once said, one can only be disappointed if expectations are missed ... and since we don't know the PLAAF's plans, schedulde and performance requirements, it's only possible to be personally disappointed.
Or do You speak as the PLAAF C-in-C ??
As such let's wait how many of these will be build, when will they be depolyed to a unit and when the first serials will roll off the production line.
