The S-300V/SA-12 Giant is an ABM with fins on the upper stage and a very large booster.

The SM-3 series follows an incremental design process where the missile body and boosters for Block I is recycled from the SM-2 ER series. Had it been a clean slate design as a PLAN ABM would be, the size ratio of the booster and upper stages wouldn’t necessarily be what it is today.

I didn't say that having fins on the upper stage = unable to be ABM. After all, I directly mentioned SM-3 in the same post, which has fins on its upper stage after its booster.
I was addressing the comparison to THAAD specifically, which alexander had made based on the images, which the YJ-21 one did not show the fins in the given frame.


As for the YJ-21 itself, to me it looks like the first stage/booster stage is as long, if not a bit longer than the upper stage, which while not incompatible with an ABM design, is slightly deviating from the norm. THAAD adopts such a configuration, but its upper stage is also finless.


Overall, my belief regarding this missile's identity, is that based on the timing of the emergence of this video clip, and the noise being made around it thus far, it seems more consistent with the expected YJ-XX ship launched AShBM/HGV, rather than the HQ-26 or HQ-19 ABM.

It's long been rumored that China has been developing the next-generation anti-ship missile, YJ-21, although it's not clear whether YJ-21 is ballistic or hypersonic.

Below is a screen capture from a presentation some years ago by Rear Admiral Zhao Dengping, former deputy director of Bureau of Naval Equipment, in which he talked about future development of PLAN anti-ship missiles. The first bullet is hypersonic anti-ship missile, the second anti-ship ballistic missile.

So we are expecting two type of ship based ballistic missile: one with the elongated/double cone (like DF-26/LRHW/CPS) vehicle and the second with a glide vehicle (DF-17/ARRW)

I think there were two projects like you mentioned to control the risk. But the glider one is the real objective. They will arm the double cone thing only if they felt urgent need and couldn’t wait for the glider.

Why develop a new ASBM though? Isn't the YJ-18 already really good? Could it be a hypersonic interceptor instead?

first, YJ-18 is not a ballistic missile
second, take DF21 as comparison, which is 1.4m diameter and 10.7m length with 2000 km range. Missile which fit VLS of 055, which is 850mmX9m, is probably to have 1000km plus range. That range is far beyond all anti ship missile in service.

I'm trying to think of operational situations where a ballistic missile would need to maneuver right after launch, as seen in the video.

Iskander missile launch videos, for example, seem to show a fairly straight trajectory after launch until some medium altitude...
