My position is that I do agree that China needs more of everything in the event of a direct conflict, what I strongly disagree with is the notion that the PLAAF does not already have the necessary PGMs equipped for (at a minimum) field testing and training, because ultimately working out bugs in both doctrine and weapon systems needs to be performed even if a piece of kit is not adopted en mass, and that takes way more time than manufacturing any type of PGMs.
Right, so I want to explain my threshold for why I think the PLAAF almost certainly does not have the necessary PGMs for field testing and training.
For new aerial weapons/payloads, we generally see their transition from initial industry development -> initial service fielding/tactics -> widespread service in a certain manner.
Initial Industry Development: we see one or two pictures of a test article on an aircraft or two. Sometimes, for certain weapon types, they are first "revealed" at a defense expo at Zhuhai, which is usually indicative of a relatively advanced level of platform/payload testing occurring. However, note that this is
industry development. That is to say, it has yet to enter initial fielding with the PLA and initial tactics testing with the PLA -- this stage comes next.
Initial Service Fielding/Tactics: in this stage, it is the first sign that the
PLA has procured a new weapon type en masse or is intending to do so. It is the part where they field these weapons in a few units to start off with, to develop initial tactics and likely writing the book for how to handle, operate, maintain those weapons, and the best ways to utilize them. We usually get images or sometimes even brief video clips of this, and it usually emerges may be a few years after the "Initial Industry Development" stage. However, these images is usually only seen on aircraft from one, maybe two units. The weapons are not widespread.
Widespread Service: this is the final stage, and usually is visible a further 2-3 years after the "Initial Service Fielding/Tactics" stage, where the new weapon is basically widely proliferated among the PLA in all of the aircraft units intended to field the weapon. We gradually get multiple pictures (official and unofficial) of aircraft from a variety of units carrying the new weapon, deploying and training with the new weapon, and seeing the new weapon at given air bases.
For me, the only unpowered PGM that the PLA has which has reached the "Widespread Service" stage is the 500kg LGB (LT-2/GB500/LS-500J/whatever name it is). We see this weapon on JH-7/As and J-10 variants, and its status as a "Widespread Service" weapon was basically confirmed sometime in the mid 2000s, and since then we've had consistent stages of it being employed by those platforms.
However, for other PGMs -- whether it's any weapon of the FT family, or the extended LT family, TL PGM family, or the LS family -- we have not seen any evidence of those PGMs entering the "Initial Service Fielding/Tactics" stage let alone the "Widespread Service" stage.
Indeed, it seems that for those weapons they have only existed at the "Initial Industry Development" stage, and we haven't had any signs of the PLA buying them in even a small number to start to train with them and develop tactics of them -- and
we require evidence of this, we cannot just assume the PLA are doing it.
In the last couple of years, the only new PGM that we have seen which the PLA might have allowed to reach the "Initial Service Fielding/Tactics" stage is a new 100kg LGB type weapon (pic below), however even in that image it is not exactly encouraging because they're installing it on what appears to be a JH-7/A and on a single pylon rather than a multi-ejector rack, completely wasting the purpose of having a smaller weight bomb. Additionally the bomb itself is a rather large footprint for such a small weight, and lacks the wing kits of other 100kg bombs in existence (like SDB, SPICE 250, or Chinese industry options like TL-20, FT-7).
In short -- there's a lot left to see and confirm, and at present the only PGM that we can confirm the PLA have in widespread service is the 500kg LGB. There is possibly a 100kg LGB that the PLA are starting to field, but is one that is suboptimal in footprint and carrying capacity.
