link Mk. 41 is 22" inches (55.9cm) square while Mk. 57 is 25" (63.5cm) square. If the dimensions given are correct, measurement for Chinese Universal VLS is 23.5" (60.1cm)

Cross-sectional area:
Mk. 41: 3125cm2
CUVLS: 3612cm2 (+16% vs. Mk. 41)
Mk. 57: 4032cm2 (+29% vs. Mk. 41)

Of course at this point Mk. 57 is basically a waste of space given that nobody is going to be producing munitions that can be equipped on only three ships.

Where did you get the 23.5'' (601mm) from? I thought it was 850mm diameter, and as a circle contained within a square, the square has to be at least 85x85cm in size.

 

[Lethe]

A square cell with diagonal measurement of 85cm gives sides of 60.1cm via Pythagoras.

There may be other ways of interpreting Blitzo's figure, but my interpretation has the benefit of coming in between Mk. 41 and Mk. 57 in size, which is very plausible, while an 85x85cm cell would be more than twice the size of Mk. 41 and some 80% larger than even Mk. 57, for no readily apparent reason.

for sure but in your scenario the figure of 850mm becomes irrelevant....

the largest diameter you can fit in the box becomes 601mm

Since when did anyone measure VLS by it's square diagonal length like a TV? I was always under the impression that it's the circular diameter that's measured.

 

[Lethe]

If China's universal VLS cells are really 2.3x the size of Mk. 41 cells then I expect that would be open to visual confirmation.

Yeah 0.85m diagonal length is almost certainly wrong.

 

[Blitzo]

Still hanging on to hope about that amidships prediction of yours I see.

And the aft mast as well. I think the spotter's CGI also gets the helipad's length a bit small as well compared to a satellite photo that we recently had.

At the end of the day, I think the amidships and after mast possibility remains one which is not settled and preferably requires something firm to settle, like a clear photo. For the sake of caution I think it would be premature to call it just yet.

Diameter of the cell is 0.85m. if you place a circle in a square, the diameter of the circle = length of each edge of the square.

Putting it another way, it is 0.85m x 0.85m

It would, if you get close enough of a picture. Keep in mind that Mk41 uses a dedicated exhaust port while the CUVLS uses each individual cylinder as its exhaust ports, so the 2x4 modules are not as different in size as individual cylinders.
