170 DDG AshM launchers: Opinion needed

These pictures are from the CDF and other Chinese forums, and attached here.

These pictures leave me with quite a number of question marks, and I think it is very intriguing.

Contrary to earlier impressions, the angle which we can now see the stands starts to tell me something. Instead of the missile containers actually laying across the stands, they actually sit into the “holes” between the columns or supports of the stands, and the supports actually “hold” the cylinders in their places.

The AshMs, therefore, are not launched from nearer to the horizontal slant position, as typical of the C-80X series, or with many known AshMs. They are launched from a near vertical slanted position.

The diameter of the “holes” in the stand, as well as their height, suggest that these are quite big missiles, perhaps supersonic or one with quite a long range.

If so, these are missiles I have not seen before, or one that I cannot equate with any known Chinese or Russian type. This is either a brand new Chinese missile, or if this is Russian, I suspect the 3M54E1, which is said to be launched from a near vertical position.
