IMO JH-7B or its improved model can replace J-7s or Q5s. Jh-7B may have some upgrades and may be tailored to fukfill different roles to replace J-7s. A modified version may also replace Q5s. When PLAAF/PLAN is satisfied with J-11d and J-16 and able to manufacture 175+ annualy, they would be used to augment/replace older Su-27/J-11a/J-11bs.
When J-11d/J-16 induction reaches to 1000s then J-7s may replaced.
It all depends upon performance of J-11D/J-16 as well as J-20/J-31 and their integration into the PLAAF/PLAN.
Sorry, but please stay realistic ! These are only utter fan-boy wishes .... a production rate of 175 is simply unrealistic. If You compare the production rate for the J-10B at CAC, we have now 3 per month or 36 per year and I think SAC only has a similar rate ... in regard to the J-11-versions even lower during the last years.
As such a rate of 175 per year = nearly 15 per month ... simply forget it, or SAC will have to manufacture Flankers for the next 28 years. As a consequence - and again more fan-boy-dreaming that based on PLAAF/PLANAF-requirements - the PLA will never introduce 1000 J-11D and J-16, not even if You include the J-15).
Therefore I honestly beg You to think before You post ...
