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

Both the Yasen and the Virginia had a stated/target silent speed of 28 knots (52km/h), which is a curious coincidence.

So I think that represents some sort of hydrodynamic limit for cavitation, whether due to the hull or due to the propeller tip speed

The Yasen and NSSN designs are over 20 years old now, and we can see that the latest Type-093B have pumpjets and likely quiet or natural circulation reactors, which means they have surpassed the Los Angeles class.

So I suspect the Type-095 has been designed with a silent speed of 28 knots, comparable to the Yasen and Virginia.
Additionally, in a situation where technical developments among competing national sub designs all reach a common structural design plateau, then information processing and response time becomes more critical to a design's combat effectiveness.

Here is my latest video on the known features of the Type 095 SSN.

Thanks everyone for your contributions on this forum, it has been a great source of mine.


In Mandarin “o” is pronounced “all”. “Bohai” is pronounced as “ball-hi”

No, the pronunciation of "Bohai" in the video is correct/pretty close, putting aside tones. The 渤 in 渤海 might be pronounced "ball" in some other dialect(s), but not Mandarin.

Do we know if the VLS tubes on 09V are behind the sail? Having VLS tubes penetrating the pressure hull makes it weaker structurally which might penalize maneuverability and diving speed. 12m diameter should provide enough space for 2 rows of multipack vls in front of the pressure hull. Perhaps the sail on the 09V is further back compared to the 09IIIB becuase vls tubes are installed in the front.

The pictures posted in this thread so far are not of sufficient resolution to know for sure. I think the best one we have currently is the one in post 1852 which is too blurry to be certain but it seems to me that it's possible there's some VLS before and some after the sail. Keep in mind the VLS in 093B is after the sail so it seems PLAN is fine with having VLS there.

It is not definitive, but it is more likely. The bow of 09V likely is used to accommodate a larger torpedo compartment as well as a larger bow sonar apparatus.

Considering other recent major SSN types have seen additions of major VLS banks aft of the sail in the pressure hull itself -- Block V Virginia additions, Yasen/Yasen-M, 09IIIB -- it wouldn't be odd for a VLS bank to be aft of the sail rather than forward.

The video pronounced it right. 渤(海) is spelled as Bo, but in practice it is pronounced as Buo. There is a slight u sound ahead of o. English word all does not have that u. The closest English sound is four.

There is a big controversial of whether O or UO is right in spelling certain words. It even reached the ministry of education who insisted on O being the standard spelling. Interestingly most people assumed UO in place of O (the standard spelling) including myself. I only realized this "mistake" when looking up in dictionary.

The following link quotated a member of the standardization as saying that o is a shortened version of uo in spelling, meaning it is written as o but pronounced as uo, example is bo po mo fo are actually pronounced as buo puo muo fuo.

This link stated 99.8% error rate of o. It is like saying nearly all Chinese are wrong since the creation of standard mandarian except the very few "experts". How ironic is that!

有学者调查发现,“o”的误读率达到了99.8%

I personally must say that both the linguistics and the ministry are trying to defend their bad choice of spelling scheme (1950s) in their work (the standardization) ignoring the actual practice of the population.
