New SSN (09X?) thread

Xiyazhou did elaborated more on his initial post, here are the summary of the relevant part:

- 09IIIB was only built en masse due to 09V being delayed

- 09V has gone through atleast one major design revision as the original design was considered too conservative

- Both factors mentioned above caused 09V to become almost like a "parallel project" to the new SSN in timeline

- The overall design of the new SSN is a massive improvement over traditional design; despite using the same (or similar) set of propulsion arrangement, the lack of a sail would mean the new SSN will have up to 15 percent drag reduction at high speeds which means significantly improved top speed.

- The sail is also the second largest cause of noise at high speed after propulsion, removing the sail would effectively remove a major cause of noise at high speeds. If your propulsion arrangement is silent enough (09V's nuclear IEP is mentioned to be SOTA globally), removing the sail would result in an extremely quiet submarine even at high cruise speeds.

- TWZ's statement on this new SSN being sort of like an underwater interceptor is partially correct, this SSN is designed to track and destroy American underwater assets efficiently between the first and second island chain.

- As a dedicated hunter killer, this submarine likely does not have any VLS cells (Though, we know now that this is likely incorrect as there were some VLS multipack tubes spotted, but given the minimal amount of only ~12 cells, I don't think this changes the conclusion much) and instead rely purely on a large amount of torpedo tubes like the Seawolf.

- This submarine may also be equipped with larger than 533mm tubes to launch UUVs, Xiyazhou expects all future designs to include provisions for these "underwater loyal wingmans".

- It is also possible that this submarine will include smaller 380mm torpedo tubes to launch dedicated anti-torpedo torpedos for active defense, as with how fast sensor technology is improving, current countermeasures like bubble decoys or jammers may become insufficient in the near future.

- There were already some rumors about this in the past, but he did not expect it to come so fast. It is now possible that the Type 09V will not see mass production.

I'm kinda curious which company he's alluding to that transferred nuclear tech so China could complete 09v.

Guancha has a weekly big military article that's published on the weekend and this week it's Ayi's turn to write it. He said he was several thousand words into writing about this new sub when orders came from above telling him to drop the subject, so he's starting over on a completely different subject.

He finishes up his statement saying "this is a weapon with the potential to change human history, we must treat it with respect."

A 15% drag reduction would mean a 5-7% increase in top speed?

And a sailless hydrodynamic design would be quieter/faster than any other submarine in the world.
Technically the original Chinese text was "(the new sub) effectively gains around 15% propulsive power at high speeds", Im no expert om subs so can't really make conclusions here

Several days ago Otter joked that it might be a huge nuclear torpedo, and assuming the yield ratio is 3kt TNT per kg, this torpedo's yield would be 27 BILLION TON TNT. It's more than enough to change human history.
Maybe not something that extreme, but another possibility is SSN(S) being China's own Poseidon carrier? Considering how hush-hush everything is about it, no one really knew (or said anything) about it, chinese denizens can't talk about it etc.

I'm not sure why people are letting their imaginations escape so far into thinking this is a strategic weapon.

Just being a future focused high performance SSN is enough to qualify as being able to change human history...

I will venture to disagree on this point. While the aircraft analogy is necessarily imperfect, a similar design philosophy can be observed in how both 6th-gens are explicitly oriented towards air superiority missions—not strike ones. That is to say, aircraft optimized for A2A combat, to destroy enemy aircraft, and ultimately to win control of the air. Strike missions and platforms are clearly a secondary priority at this stage.

It seems quite plausible, poetic even, than PLAN is likewise laser-focused on using its own next-gen platforms to win control of the (under)sea. Presumably the logic is that, given the disproportionate degree to which US and co. are dependent on air/sea control to conduct and coordinate distant operations along exterior lines from otherwise isolated island bases, contesting and disrupting said control yields disproportionate benefits to the country with interior lines along a giant continental landmass and associated benefits w.r.t. force (re)generation, (re)supply, logistics, etc, in-theatre by default.

In that case, the question then becomes how China would be able to conduct massed and sustained standoff strikes against land and sea targets far beyond the reaches of the PLAAF H-6K/J and PLARF MRBMs into the CentPac and EastPac, let alone the West Coast and East Coast of CONUS, in order to degrade the US's war-making and war-waging capabilities, without having a substantial fleet of SSNs that are able to provide massed standoff hypersonic and/or ballistic firepower to the target?

Yes, we do know that there's the DF-27 - But the purported maximum strike range of ~8000 kilometers would only enable the coverage of Hawaii and the northwestern CONUS (e.g., Kitsap), leaving the rest of CONUS untouched. Developing intercontinental-range conventional strike missiles (somewhat similar in a sense to the Global Prompt Strike idea) would mean a lower cost-vs-benefit ratio, alongside an understandably lower number of missiles that can be procured and deployed.

As long as China doesn't have any footholds up to the 2IC (at least), I certainly don't see how PLAN CVs, CGs and DDGs would be freely sailing within the vicinity of Hawaii, Kitsap, San Diego, or even Norfolk and Newport News to launch strikes against the naval bases and shipyards there, in addition to Palmdale (B-21 production site) and Fort Worth (one of the three F-35 production sites), among other industrial and military sites dotting all across CONUS for the foreseeable future. This is in contrast to how China's eastern seaboard is well within range of the 1IC and 2IC (and that there were never any guarantees of 100% defendability against enemy strikes coming from these island chains and beyond).

If the 09X is an even more "undersea superiority" platform than baseline 09V already is, I could see them going for a dual fleet of 09X and a heavier VLS load "09VA" variant in the future (and even 09X likely would still have some VLS albeit a bit lower than 09V at baseline possibly).
Such a fleet would be a balanced mix of "undersea superiority" and "undersea superiority+land attack" in role.
What is the actual, more ridiculous notion though, is the idea that the PLAN would really be willing to commit to an active SSN production line characterized by "all ~12m pressure hull" (for 09V/"VA" and 09X, assuming 09IIIB production sunsets in near future).

That would be immensely ambitious.

Aren't these two essentially contrasting/conflicting POVs? If not mistaken, aren't we kinda expecting both the 095 and 09X to have ~12 meters of hull diameter at this point?

By taking footholds, obviously. History already shows us how you fight a major war across the Pacific. Time has not changed the laws of physics, nor has it changed the fundamental need to control territory by putting boots on the ground. The fact that ground is so scarce in the vast Pacific only makes each scrap of it more precious. So if you want to send ships into the vicinity of Hawaii, Kitsap, San Diego, or even Norfolk and Newport News, then you need to island-hop your way over there.

Relying on fires alone to achieve decisive outcomes, be they standoff or stand-in, delivered by bombers or ballistic missiles or submarines, is exactly how you end up in the mess the US is stuck in now with Iran.
