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

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.

on 12m hull for 09V. I think Tom Shuggart a year or two ago spotted hull modules that were 12m at Bohai shipyard, so I think it's not unreasonable, especially if we consider that's how big the Seawolf are and PLA has been building large platforms across its service (like 055 and 076 for example). Also probably more importantly, if they intend to install a larger and wider VLS module on 09V.

I specifically made the diameter 12m due to these spotted modules. I don’t think there is any sub in the PLAN arsenal that is 12m in diameter? There were also 14m diameter modules were spotted as well, likely for the 09VI.

The 12m pressure hull (single/hybrid configuration) for 09V is also a rumour which predates the suspected hull modules spotted on satellite.

In fact the whole notion of 09V being more of a "Seawolf-sized" peer rather than "Virginia-sized" peer is something that goes back nearly half a decade.

Given SSKs and SSKNs, they would be suited to the vast majority of littoral missions in the 1IC and ASEAN.
So the it would make sense for the 09V to be optimised for deep ocean, long-distance, long-duration missions.

And for the next 5+ years, the 09V would be the only platform that could realistically operate beyond the 2IC.
It would have to operate by itself, so that pushes towards a larger submarine.

What's the point of 093B if it cannot operate beyond 2IC?

Just on the specifications, I think one of the key attributes is the maximum "silent" speed, which is presumably comparable to ocean background levels.

That is so useful from both a tactical and strategic perspective.

The Seawolf is listed as 20 knots, but I recall the Virginia is somewhat higher?

I think one of the use cases would be for a Type-09V to have 3000km land-attack hypersonic missiles, as SS(G)Ns would be the only platforms which could realistically deliver conventional weapons to CONUS (West Coast, East Coast and the Gulf Coast) for the next 10 years.

Even a modest capability would significantly alter US perceptions and calculations of a China conflict.

It would also force the US to invest much more into missile defence.

Hey guys, just a general feeler here. Are Chinese submarines still considered noisy compared with their US counterparts? In general? Have they made any progress where they are major threats to US detection?

The Seawolf class is still the submarine that generates the least noise in the USN service. In fact, the being built Mark V Virginias, being ridiculously long because of extra VLS modifications, may not be as quiet as the Mark IV in service right now. In reality, "silent" speed is when noise coming from propellers and the reactor complex is negligible, but the flow noise coming from water being pushed around by the hull always exists, is a lot louder than the ocean background noise and can only be mitigated by better shaping. Water is not a superfluid, and thus submarines with weird proportions such as the newest Virginias, causes, problems.
