Rumors suggest that the launch canister of the HHQ-9C has a diameter of 470mm which is larger than the 425mm maximum required to quad-pack in current 850mm VLS. However the new 950mm VLS launcher is already in testing and will probably included on next generation destroyers, which is sufficient for quad packing HHQ-9C. Just wait another 5-7 years and you'll see the new ships.

Do you know about/have access to the revelant academic papers/patents/tender documents on this 950-mm diameter VLS cell?

Because from what I scouted, there appears to be a 1200-mm (1.2-meter) diameter VLS cell which is (also) in development, though no clue as to how accurate this claim is, and neither do I have access to the relevant academic papers/patents/tender documents.

Speaking of which, I did some fumbling around with the presently-fielded 650-mm VLS cells (for FFGs) and the 850-mm VLS cells (for DDGs), alongside the purported/claimed 950-mm VLS cells (said to succeed the 850-mm VLS cells) and 1200-mm VLS cells (said to be the LVLS cells) in order to find out the theoretical maximum sizes of the respective VLS cells for comparison.

Here are the results.

Firstly, calculating the cross-sectional area of the respective VLS cells:
VLS Cell SizeCalculationsVLS Cell Cross-Sectional AreaPercentage Jump From Preceding VLS Cell Size
650-mm0.65 m x 0.65 m0.4225 m^2-
850-mm0.85 m x 0.85 m0.7225 m^2~71.01 %
950-mm0.95 m x 0.95 m0.9025 m^2~24.91 %
1200-mm1.20 m x 1.20 m1.4400 m^2~59.56 %

Next, by setting the 850-mm VLS cell depth at its maximum of 9 meters (strike version) and scale the other VLS cell depths accordingly:
VLS Cell SizeVLS Cell Depth (Rounded-off)
650-mm7 meters (set)
850-mm9 meters (control)
950-mm10 meters
1200-mm13 meters

Lastly, by including the depth of the VLS cells for the calculation of the respective VLS cell volumes:
VLS Cell SizeCalculationsVLS Cell VolumePercentage Jump From Preceding VLS Size
650-mm0.65 m x 0.65 m x 7 m2.9575 m^3-
850-mm0.85 m x 0.85 m x 9 m6.5025 m^3~119.86 %
950-mm0.95 m x 0.95 m x 10 m9.0250 m^3~38.79 %
1200-mm1.20 m x 1.20 m x 13 m18.7200 m^3~107.42 %

As can be seen, while the jump from 650-mm VLS cell to 850-mm VLS cell is bigger than the jump from 950-mm VLS cell to 1200-mm VLS cell, yet the differences are actually pretty marginal, all things considered. Besides, the capability upgrades from the 650-850 to 950-1200 certainly cannot be understated either (i.e. enable the multipacking (2x or 4x) of larger-diameter missiles for the 950-mm VLS cells, while offering significant upgrade in surface strike capabilities for the 1200-mm VLS cells).

Some kind of new front superstructure, it is said to be around 20m wide.

First note: That structure certainly doesn't resemble the fore superstructure on the 055 DDGs (as shown below), let alone the 052D DDGs:

With the absence of angled faces at the backside of the structure, it seems to suggest that the 4x AESA radar panels are actually group in two pairs (namely, one pair located at the fore superstructure and covering 180 degrees forward, and another pair located at the aft superstructure and covering 180 degrees rearward).

The relative locations of the two AESA radar panels also seem to suggest that the bridge will be located below them and not above (and are situated higher up in the ship's superstructure compared to those on the preceding 052D and 055 DDGs).

Addendum: The structure is about 24-26 meters wide (give-or-take some inaccuracies due to hidden edges) which is even greater than the beam of the 055 DDG.

Therefore, if this structure is a realistic, 1:1 representation of the real thing - Could this be referring to the 055-successor CG?

Or, given the size, this is a structure for a CV, perhaps? :)
