China uses its Su30s as strikers first and foremost. There is no need to integrate PL15s on them given the large number of air superiority focused fighters China also have fielded.

Why not? What will be the negative? Cost will be negligible, capability will be significant.

Its the opportunity cost that matters. The people doing this sort of work always have other projects they are working for. To divert these people to work on this sort of stuff means that their projects will get pushed back considerably.

Who knows what these people are working now? Maybe it is better for them to just focus on their current projects and leave the plane as it is

And what happens to all the Russian made Su30 munitions if you switch radars? How much time and money will it take to re-integrate all those legacy munitions onto the new radar?

And after all that effort, just how often do you want to hang PL15s on your Su30s on strike missions? Bear in mind that those PL15s are significantly heavier than PL12s.

But... There is a midlife upgrade you almost have to do anyway and J-16 sub-systems are already there! Those munitions have a shelf life, too which I am pretty sure shorter than Su-30 airframe lifespan.

So, I agree that upgrading Su-30s with PL-15s probably isn't worth it, but don't agree with the reasoning.

1. I think integration of PL-15s on older 4th gen aircraft lacking AESAs is viable, because going forwards I expect cooperative engagement to be the name of the game. Giving Su-30s PL-15 capability will not give them the ability to guide PL-15s themselves, because they can be guided by friendly 4+, 5th gen aircraft. That is to say, the Su-30s should be able to continue to utilize its current sensors and existing weapons suite (including whatever stocks of Russian weapons they have left) -- if they wanted to add in PL-15s it should not compromise the rest of their weapons availability, because PL-15 upgrades could conceivably be made with only datalink upgrades rather than overhauling the entire sensor suite.
2. Su-30s are not a dedicated strike aircraft as operated by the PLA, they are very much multirole in the same way J-16 is. Giving a multirole aircraft a more capable A2A weapons suite is very much sensible.
I also want to clarify the A2A capability of the Su-30 in context -- for a period from the early to mid 2000s, the PLA's Su-30s were easily the most capable A2A aircraft they had by virtue of them having a reliable ARH BVR capability for the first time with a decently capable radar. Even now, today, they are not operated exclusively as strike aircraft in the way JH-7/As are. They remain multirole aircraft.



But... There is a midlife upgrade you almost have to do anyway and J-16 sub-systems are already there! Those munitions have a shelf life, too which I am pretty sure shorter than Su-30 airframe lifespan.

... Continued from above.... the reason why it doesn't make sense to give Su-30s PL-15s, is because of priority.
At present, priority for new PL-15 production obviously would be first going to new build 4+ and 5th generation aircraft -- i.e.: aircraft that can guide PL-15s with their own fire control systems. Given the number of new 4+ and 5th gen aircraft being delivered per year, I suspect PL-15 production is probably going to be prioritized for them for a while yet.
That is to say, I doubt older non-AESA 4th gen aircraft will receive PL-15s and the requisite datalink upgrades until PL-15 production capacity is significantly expanded into the future.

In the case of Su-30s specifically -- those Su-30s were flown very, very hard from when they were delivered to now. There are probably not many airframe hours left on them, I expect them to start being retired by mid this decade.
I very much doubt the Su-30s will get a mid life upgrade, because if they don't do a deep structural overhaul of the airframes, a mid life upgrade of weapons suite and avionics suite doesn't make sense -- and on balance, I suspect it would be easier just to order more J-16s which are much more compatible with the overall PLA infrastructure and logistics tail as well as substantially more capable (or if they don't want one for one J-16 to Su-30 replacements, they have J-10Cs and J-20s that they can choose to replace given units, as well as carrier based and land based J-XY production that will begin from after 2025).
So, IMO, given the likely retirement of Su-30s looming just on the horizon, giving them upgrades to accommodate PL-15 and giving them PL-15 stocks just doesn't really make sense.

China doesn’t even have that many Russian AA munitions left. Only legacy flankers still use them.

A much better version of a previously shared image.

Can anyone please tell me if this is J-16 or SU-30?

I think they bought a significant quantity of Russian AG munitions over the many Su30 purchases, since at the time China was buying with war in mind given the Taiwan crisis that propelled PLA modernisation into high gear. Who knows how much is left?

Something else to consider is that the fact that those munitions have finite shelf lives that they are fast approaching may be another reason why the PLAAF is in no hurry to MLU their Su30s - they may well have decided to get as many years use out of the Su30s as possible since they can be used to give pilots invaluable experience with using live munitions without running down inventories of newer and better Chinese made smart munitions.

Remember that training is a perishable skill, so you don’t want to use your stockpiles wisely to give as many pilots experience as frequently as possible. As such I imagine the PLAAF would have drawn up a detailed multi-year schedule of how much munitions to use each year to maximise their training value over as many years as possible.

Once those munitions stocks start to run low is when I would expect to see the PLA start to upgrade their Su30s with modern Chinese radars and avionics (so no more support of imported Russian stuff). There will still likely to be a significant proportion of munitions left when this starts, as the upgrade of the whole fleet may take years and the PLAAF would not want to have such an important part of their fleet essentially toothless for so long.

It would not surprise me if a decide part of the fleet is never upgraded and just kept around in this training role and eventually retired once all the old munitions have been used up.
