It's hard to say how much is being produced and if it is out of domestic production because of PLA OPSEC but from what I gather from what @Deino has said J-10C is still in production just very low volumes. Perhaps that has changed in the last year or something but it's hard to know.Note that the 2nd AB used to fly J-10Cs, a type which AFAIK has been out of domestic production since ~2022. Yet, in late 2024 we saw that the 44th AB had transitioned to the J-10C. As such, I'd suggest that the 44th AB's new J-10Cs are in fact the 2nd AB's former J-10Cs, transferred after the latter unit received new-built J-20s some time last year.
