Personally, i think the best role for the flanker is to make it into a dedicated strike platform and take full advantage of its range and payload. So the development of the j11bs is probably more significant.
but then that would need to compete with the jh7a and rumoured semi stealth striker they r developing.
J-11BS should be significantly superior to JH-7A and significantly inferior to a 5th generation strike aircraft. I don't think PLAAF will take the risk of totally relying on the 5th generation strike aircraft development. They will definitely need J-11BS to fill the gap.
Incidentally, we've seen J-11BS prototype in yellow primer. I don't think we've seen it operational in a regiment, have we?
i don't see how saying certain J-11s will be converted to J-11B avionics/weapons and building new J-11Bs conflict with teach other. Do you think they are not trying to get new flanker regiments?
He means that there must be building new J-11Bs, not just upgrading old J-11A's, because some airframes are just too old to be upgraded and need to be retired.
For the latter it's easy, since a "B" has the MAW's, the new HUD (but not all) and most noticeable the black radome (and hopefully some day the WS-10A) !
Do you mean that the newest J-11Bs look like they are using AL-31F?
That is strange.... PLAAF doesn't have enough Russian engines for both production of J-10s and J-11Bs. It's unlikely they would use up the existing stock of engines for the two engined flankers instead of single-engined J-10s.
If we confirm that the newest J-11Bs look like they are using AL-31F, it suggests that the final production version of FWS-10 is visually indistinguishable from AL-31F.
