Rumoured "mini-nuke/diesel" Submarine SSK-N(?) thread

[W20]

Okay

We remove the miniNuke so that it doesn't break down one day and we leave only the electric motor and a very big bunch of batteries now that we have more space after throwing the diesel generators overboard, the miniNuke and we throw overboard or in a more civilized way we leave on land, in port before setting sail, the majority of the crew, except the cook, of course, who is sacred

Oh wow, at this point someone could probably seriously look at a pure electric boat. Probably for near shore patrol or SCS patrol. Also isnt Li-S sorta of a new battery technology for boats?

Edit: Quick question, did this study assume the entire sub was just a big battery or was it more realisitc?

 

[W20]

On the one hand there is the battery revolution and on the other hand there is the issue of new passive sonars:

high-performance ultra-sensitive fiber-optic passive towed array sonar

At the intersection of these two paths is the idea of this submarine that will be freed at the same time from diesel generators, tanks to store diesel and AIP system tanks, leaving a clean and functional design: an incredible submarine for silent patrol

All electric was a Japanese idea, I mean what was known in the West from open sources

This Chinese idea of the mini nuke is more brilliant

miniNuke -- Battery -- Electric motor

 

[W20]

Electricity consumption

is the sum of

Electric motor + the so-called "Hotel"

The numbers in the Japanese idea or fantasy above seem to not include "Hotel"

which on the other hand raises the question of whether at some point in the future this type of submarine will be manned by robots

An electric submarine keeps its batteries charged, because batteries are for high-speed maneuvering.

The silent hunter's silent patrol is at low speed, about 3 knots, so as to not be detected and on the other hand not to make noise to the sensors.

And submerged at low speed the consumption of the Electric motor is very low: the Japanese numbers above serve to illustrate this issue:

a) fast maneuver @ 20 knots
b) navigation to the silent patrol zone @ 10 knots
c) silent patrol @ < 5 knots

and as pointed out in this thread the improvement of "Hotel" is important because it greatly improves the ability to Endure time submerged with oxygen to breathe, hot water and a good cook

 

[W20]

Let's assume (Achtung: it's just an exercise in imagination)

Let's assume that the new fiber optic sensors can detect 100 km to the port side and 100 km to the starboard side, so under this imaginative assumption 5 submarines on silent patrol cover a front of 1000 kilometers (!?)

Ok, let's be realistic: maybe 10 submarines on silent patrol could perhaps cover 1000 km, I don't know, the point is that a destroyer at high speed hears little and a submarine at low speed has much better hearing

Yeah, there is more risk, but it’s worth it to get VLS in there, no? I think we can say China makes reliable machinery that can be trusted in war time, that’s what they are aiming for.

What does it need VLS? If the furthest you want to operate this is second island chain and you already have overwhelming firepower in second island chain, then other factors like stealth, crew comfort and speed are more important.

I do not believe batteries alone would allow for sufficient backup in the case of reactor failure in the open seas

It’s possible that you could get back to port with a fully charged battery depending on how large battery pack is. In practice, nuclear electric components will be large enough that battery size probably won’t be more than a couple of MWh.

Why not just build larger UuVs if you are going to do this?

I mean they clearly already have XLUUV program for this type of mission. But they also clearly see a need for mini nuke.

 

[zyklon]

What does it need VLS?

Not to say the YJ-18B is an inadequate missile, but the PLAN wouldn't be arming 055 DDGs with AShBMs if tradeoffs weren't in play.

So it's plausible the submarine in question will be equipped with VLS cells to launch AShBMs and/or other missiles that are incompatible with its torpedo tubes

I really don't think you want to put AShBM in something like a 3600t mini nuke. If it is not meant to go outside of 2IC, then every plausible target it can reach would be better targeted via other assets. Anytime you launch missiles from a sub, it has to come up to periscope depth to do it, which reduces its stealth.

It's one thing for 093B to do it, because it's in the middle of Pacific Ocean and has the speed to scoot away afterward. And no other assets can really deliver missiles against San Diego. You don't get the same rationale for a sub that's just operating within 2IC.
