I think Pantsir is a good system but just in a bad operator's hand who fights against a strong opponent. Can't really blame Pantsir.
Maybe not, but PLA used to operate Type-95 SP-AAA/SAM combo before, but now it's on it's way out with gun-only PGZ-07 as the replacement.
PLAN operated Kashstan gun/missile CIWS, but there hasn't been any similar domestic systems except for models in export trade shows.
To me, this is showing that PLA is not interested in these types of systems. I don't have any concrete information on this matter, so this is my own hypothesis.
Similar to what I posted on the SAM thread. It could be that the engagement envelope of missiles and guns is too different. PLA SHORAD missiles are at least double the range of guns (Pantsir 57E6 is triple). If you combine the gun and missile together, you can only engage max 1 target. Something like Tor/HQ-17 as a VLS system can engage multiple targets, and I imagine is why they invested in an AESA radar on the HQ-17. Could be a similar situation for PLAN, where ships are operating as a cooperative engagement network. HQ-10 of one ship can be directed to help another ship while 1130/730 gun can still cover the mother-ship. The disadvantage of this system is the additional cost of sensors, extra crew, and additional vehicles.
Again, I have no real source for this, but just my observation that no new in-service systems have combined missile and gun, but we have seen prototypes/tests/export models.
