09V/09VI (095/096) Nuclear Submarine Thread

[Blitzo]

Do we have any hints that they are on the hull instead of on the sail? I ask because I'm making the 09V based off my 09VI model with some tweaks. I put the planes on the sail.

09VI model dimensions: 14m diameter, 159m long, 23,600 cubic meter volume, 2.4m diameter VLS tube, 14m tall tube. 16 Tubes

09V model dimensions: 12m diameter, 135m long, 13,900 cubic meter volume, 2.4m diameter VLS tube, 12m tall tube. 8 Tubes

I think placing the hydroplanes on the hull are a more modern/contemporary practice for SSNs, so that is part of the assumption for 09V's positioning.
I think there may have been some semi-credible rumours in the past about 09V having such a configuration (as opposed to 09IIIB, which was written as continuing to have the same positioning as the prior 09III family), but I can't recall the exact details.

My own off the cuff drawing a few years back had it something like this

Also, why the big gaps between pairs of tubes? Sure, columbia is to come with quadpacks but without any real gaps between packs...

Out of interest, what's the rationale of making 09V's tube 12m long?

I admit my operating assumption was that the total length of 09V's tube is likely to not exceed 10m, partly derived from this paper (and related papers) a few years back for a tripack tube design (overall triapck tube length 9994mm, individual missile tube length 8810mm, overall tube radius 1005mm, individual missile tube radius 415mm), all of which corresponds to the sort of payloads one would be interested in loading that are compatible with the the maximal 9m length PLAN surface combatant UVLS (like submarine launched versions of YJ-20, YJ-17, and likely the hypersonic cruise missile for UVLS "YJ-XX", among others in the future -- the depicted payloads in this paper for example seems to show a weapon consistent with YJ-20)

If the 09V diameter is 12m, the prevalent hump layout on the hull's top basically gives a max tube length of up to 12m. I was using this model from SOYO from the past as a reference which is why I asked some questions about it. If the max diameter was 10m. The hull would be nearly entirely rounded.

If the 09V is only 10m in diameter, then the hump would make more sense for 10m tall VLS tubes.

A follow-up progress, with the number of multipack VLS tubes reduced to 8 to match the number of VLS cells on the 093B SSN. Made by SOYO on Weibo. Similar cautions apply.

Ah I see.

to be fair I sometimes don't understand the assumptions that go into all of SOYO's models. In any case a 10m long tube (and a more flush geometry with the hull form) seems more appropriate for a vessel that is still primarily a SSN.

I did the partitions because of this one old Chinese academic paper. It may or may not accurately describe the layout of the 09VI. This is just what I modeled it after. Personally I thought the sail was too close to the openings, so I moved the sail further forward on my model.

Some illustrations from an academic paper that I don't have access to, but these appear to depict a SSBN that doesn't match any existing Chinese design. Filing these here for documentation purposes just in case.

Here's an update:

New model, Diameter still 12m. But now the tubes are 10m long and the length I shortened the overall to 128m. Sail modified to be like your picture. Volume now 12,000 cubic meters.

Very nice.

Tbh this is about as close in major features to what I expect for 09V, as we can get (other details not included being 8 torpedo tubes, 4 mounted on each side, which is a feature mentioned by some as expected). 8x tripack VLS tubes seem like a sensible baseline VLS armament.
The only thing to await otherwise would be what the overall length of the submarine will be. There's a possibility that even with 8x tripack tubes, the length might be a fair bit smaller than 128m; some have said a more conservative 110m ala Virginia/Seawolf for 09V.

The VLS tubes im also using might also be an unrealistic diameter at 2.4m I used the same as on my 09VI model which would be for SLBM. With the paper you quoted, the maximum outer radius is said to be 1m. So 2m diameter tubes would be quite a bit smaller. With thinner tubes I can make my model even more streamlined, and shorter to the 110-120m mark I believe.

Once you're done, you should definitely consider posting it on a social media handle as a prediction/projection for 09V's features.

Because afaik, 12m hull diameter, single/hybrid hull, multipack VLS for a "moderate" total cell count, x tails, pumpjet, bow mounted diving planes, 38MW steam turbine, 10,000t ish submerged displacement, and up to 8 torpedo tubes side mounted, is about as good as we have for what it will look like.
