This is rumored to be the vertically-launched variant of the HQ-22 (HQ-22B) with quad-packed FM-3000N missiles.
Was this shared? It is being marketed as an addition to the HQ-17AE. 24 short range and 48 very short range missiles... Very probably against cheap UAVs.
Note to the mods: I can't upload photos. It says they are too large.
No, it says unmanned vehicle in chinese on the sign.What I do is upload them to imgur and then link them in if they're too big.
As for the sign for HQ-17AE, I think it is just bad positioning of the sign and/or photography because we can see an actual HQ-17AE next to that vehicle.
