09III/09IV (093/094) Nuclear Submarine Thread

[Iron Man]

I remember when some people on this forum were 100% convinced those humps represented VLS launchers and anyone who disagreed were China haters and US fanbois.

The use of the term single and double hull is misleading, when designs are tend to be hybrids, and the ballast tank arrangement differs by section.

The front of the sub would be double hulled, as well as the taper on the rear. Meaning the ballast tanks are all around an inner cylinder, or ballast tanks wrapping around an inner hull.

In between a sub can have sections that are monohulled, with no ballast tanks; or sections that have shoulder ballast tanks, where in the ballast tanks are on top. Some people also call this single hulled. Sections that have ballast tanks on the side are somehow called double hulled. European SSKs like the Gotland, Type 212 and 214 designs are all shoulder mounted ballast tanks all along its length. The Russian Amur/Lada class is also shoulder mounted. The Kilo class, Song and Yuan class have ballast tanks along the side, with the front and rear sections being wrapped around. The Japanese Soryu class is a hybrid, the front and rear sections are double hulled, or ballast tanks around an inner hull, but the middle doesn't have ballast tanks, and is single hulled.

I suspect that on the Type 094, the front section is wrapped around ballast tanks. The next section with the sail has the ballast tanks to to the side until you reach the section with the hump and ballistic missiles are. On this hump, and its quite visible, the ballast tanks are on the top where the hump is, and this section does not have side mounted tanks, making it single hulled and allow for more room within. Once you are past this section, you have side mounted ballast tanks, and then the taper to the rear propeller would have wrapped around tanks.

I suspect that on the Type 093 (small hump), the entire hump section is a shoulder mounted ballast tank which extends to the aft and forward ballast tanks that wrap around the sub. The sink hole, which is the term for the lines of holes where the air comes out of the ballast tanks, extends as a single line from the aft tank, to the middle shoulder tanks, and to the forward tanks. This would be consistent to the structure of the Type 094 I described above where the two subs are basically same sub with this middle section changed, and share common sections.

If you move the ballast tanks from the side to the shoulder, this frees more room on this entire section, and that can be used to house a larger reactor. The hump itself is there to create additional ballast tank volume.

Thanks for the detailed information.

I am one of the people who would call any sub that has part of its pressure hull being the outmost hull a mono-hull design. When I said "Chinese subs are double hulled", I meant 09III NOT to be arranged as you suggested (middle section being mono).

As of the "freeing room by moving the ballast tank to the top", it runs counter to the "larger reactor", because the supposed larger reactor is "natural circulation" which is taller not wider.

Maybe your thought is right, but then the hump would certainly not for a bigger (new) reactor.

We don't know if these are type 09IIIB, more likely one of the variant of 09IIIA.

Funny how we speculate the PLAN isn't ready to go public on the latest 09IIIB...

This sub is no longer a secret, it's only a matter of time before everyone goes "yup, that's a new submarine."

I trust that the 09V won't be a long wait from now.

Moving the ballast tanks from the side to the top would enable a section to have more room. That may or may not have anything to do with a new reactor. Just having more room amounts to a whole lot of benefits on its own.

Double hulled as people understand it. This includes side mounted tanks.




Sub mainly single hulled, except for fore, aft and waist section.



Sub with ballast tanks fore, aft and above, also known as shoulder mounted.



How this sub looks from the outside. Note the sink hole pattern.





Another sub with shoulder ballast tanks. Compare it with the Type XX1 above, the 209 does not have tanks on the side. Note the appearance of the sink holes, and once again compare that to the newer Type 093.

If there is need to such a situation, China should just send the 29th and 30th Escort Task forces into the area. That will be a total of four Type 054A and two supply ships.

Is this your imagination or are you reporting the news? If so, where is the link for this source?

媒体报道，近日在波斯湾海域美军发现两艘来历不明的潜艇，疑似来自东亚某大国型号，从外形判断是一艘093B和一艘094A核潜艇。美军告诉媒体已经出动一架P3C侦察机前往一探究竟。美方认为093B除了可以发射鱼雷，还兼具反舰导弹发射能力，就连潜射导弹也可以机动发射。另外一艘094A核潜艇战略弹道导弹，具备远程战略打击实力。五角大楼称目前尚无法判断出这两艘潜艇出现在这一海域的真实意图。而伊朗媒体最近则将此和美伊局势联系起来，认为这是变相的给伊朗打气撑腰。目前美军喊了半天的狼来了，但迟迟没有下手，到底是什么令美军犹豫不决？显然美方担心其他国家渔翁得利。伊朗媒体还称这两艘来自东亚大国的核潜艇足以逼迫五角大楼撤回对伊朗的作战方案。

Whats the point in sending 094A?

PS:

According what you posted, they got detected. Which is a big bummer....

They obviously surfaced so people can tell the difference between the two.
094A can be configured as Arsenal sub carrying 12 AshMs.
China is plenty clear in defending Iran, won't sit idle if US forces attack Iran.

Once, trade war started by US against China, China figures it has no more relationship with US, everything is possible. In my other thread I posted China sending 8000 troops to fight for Assad in Syria, securing the oil fields , won't allow them to fall into hands of US backed ISIS.

Um....? What? 094A carries DF-21D?

or YJ18,
The tubes are big enough to carry any types of China antiship missiles
