I read on this forum awhile ago (tried to find the post to no avail and lost my origin reply in the process), someone posted an article regarding j10A development cycle from testing to being in production and i calculated on average it took 3 years of testing before being put into production. To put it briefly, it took 3 years for j10A to finish testing, but the ws10a wasn't matured so they had to redesign the plane to use alfn which took another 3 years before being inducted in plaf. So i think 3 years of testing on j10b should be enough judging of past development from the j10a, unless the engline development is the delaying factor again.
Edit: in that article, i remember it said j10A origin intended engine is the ws10b, which wasn't ready. However, from tphuang post, it state FWS-10 and FWS-10A are separate projects where FWS-10 is for the flankers, while FWS-10A is for J10B, could FWS10A initially be dubbed WS10B for the intended J10A? I find that bit confusing, so hope someone can clear that up as I always heard J10A intended engine was the J10A.
Again, different budgets and priorities. Just look at how many J10A prototypes and pre-production aircraft were built.
IIRC, those pre-production J10As were never deployed to an operational unit and are still at the CFTC. That is a hell of a lot of money spent on non-frontline planes. With the J10A, that was justified because of the strategic position and threat environment China was in at the time.
Today, there is very little chance of a war with Taiwan, and the PLAAF has a vast 3rd/4th gen fighter fleet that can more than hold it's own against regional competitors and can even give the US a good run for it's money. The CFTC also has a large fleet of very capable and modern 4th gen fighters that they can use for tactical development and what not, so spending a similar amount of money and building a similarly large fleet of prototypes and pre-production models would be unnecessary and wasteful.
Simply put, the J10B is great and would be very welcome when it enters service, but China does not need it as desperately as it needed the J10A, and the CFTC certainly does not need another dozen or so of pre-production J10Bs to play around with.
