If the 095 SSNs already have approximately 12 meters of hull diameter, then the 096 SSBNs can be expected to have an even larger hull diameter, no?
The Ohios, Columbias and Boreis have around 13.1 - 13.5 meters of hull diameter in comparison.
Perhaps having a hull diameter of 13-14 meters might be indicative of the length of the JL-3 SLBMs that are to be used on the 096 SSBNs?
Maybe.
But like I said, I think it's better to not speculate too many steps ahead yet on our own dime.
We have some rumours that 09V will have a 12m hull diameter for a single hull design, and the picture of possible hull modules are that size but we don't know if the hull modules are for it.
For 09VI, we should wait for additional rumours in their own right, I think.
I *personally* think a 09VI with a larger hull diameter of 13m class would make sense, but it's possible they go for the same hull as 09V as well.
Can we tell it is single hull or double hull from the latest photo?
We can't even fully tell if it's definitely a submarine hull module in the latest photo.
That said, the cross sectional view does show us an outline of the "hull" and it looks like it is only a single hull (i.e.: it doesn't seem to be an inner pressure hull and outer hydrodynamic hull/casing).
But we don't know if the "hull" is a pressure hull or not.
And even if it is a pressure hull, that technically doesn't rule out the possibility that it could have a hydrodynamic hull/casing assembled around it later.
