@ANMDT
There's more to come. I'll post it soon.The interesting approach with Yamato was the incorporation lived lessons/experience from such classes as Fuso and Nagato .
This shows in the boilerwork and funnel plumbing for it...given the severe issues that arose from the earlier classes not designing this as a priority but rather side by side with the bridge/mast (pagoda) and weapon requirements etc. This caused a number of awkward retrofits in these classes to improve navigation, comms and overall officer viability from the bridge especially in unfriendly combat situations.
With Yamato (given it was going to be especially bigger than anything else), the propulsion had to be well prioritised (hence you see the super boiler size and super funnel approach and having it slanted away from the bridge etc).
However this eventually made Yamato class quite something of a resource hog too and it was not a marathon runner by any stretch, and thus saw limited actual combat of relevance in WW2...given the stretched logistical nature of the theatres where persistence and endurance was crucial.
The sobering lessons of real war can be quite crushing...even when you design something seemingly to handle it better. All improvements can have tradeoffs, some hidden for a long time too.

Very typical of Rusky engineering philosophy there. Either they making it faster, bigger, thicker, or just doubling down on everything without much of technological innovation. I doubt the Typhoon has acoustic dampener in the same level such as their US counterpart (Ohio class).Largest submarines ever made. Complements largest battleship ever made already in this thread.
8.25 min mark... resonant interactions "propping" up again literally...heh @anmdt
Whole video is worth a watch tho, interesting details and perspectives.
Example: 24 minute mark what kind of things sonar can detect
(this has been something popping up in forum lately overall)
Vasily, one ping only please! (Sorry couldn't resist lmao)

The latest Russian Yuri class ssbn left this double hull design if I'm not mistaken, any idea why?Largest submarines ever made. Complements largest battleship ever made already in this thread.

I am pretty sure this was the dialogue when that resonance was captured in initial tests of earlier submarine, by Russian engineers:8.25 min mark... resonant interactions "propping" up again literally...heh @anmdt
What is more surprising, the propeller doesn't seem like the high-skew propeller often seen on US and British subs of the same era. It could have been another technological challenge in those years to install a single propeller with high number of blades and highly skew to generate an efficient and silent propulsion. (also multi-pressure hulls which was have to be used due to advancement in material and construction techniques)
Guess the case of Yorktown in the battle of Midway was a very good example that almost everyone knows very well after being hit by three bombs repair efforts had been so effective that the Japanese pilots assumed that Yorktown must be a different undamaged carrier. here we are talking about the same Yorktown which was brought back to action for Midway just with in 3 days after a serious damage she recived in battle of coral sea.Damage handling in WWII era ships, the report is covering the cases in depth, and damage handling was crucial back in time, as much as firepower and armor of the ship which is highly related with training and morale of the personnel. Unlike modern era, the computations took place by hand and heavily relied on experience of commanders of particular (chief captain for stability) .
Basics of hierarchical system in ships ,the wikipedia article covers basics of the management system which similarly exists in warships with slightly different roles optimized for warships.
The link below is the report of the damage and repairs of the multiple WWII era ships suffered aerial bombardment, torpedo or explosion damage.

Probably a better material and construction technique was introduced to allow for a single larger tube. Moreover it makes more sense to install a single propeller since each shafting and gears cause acoustic raditation, also each of the propeller. If not well managed it would create a crazy acoustic signature with tonals from RPS of propellers by 1,2,3,4,5 multiples. There would be an additional noise at lower frequencies than the RPS due to an interaction occuring in wake region and probably be picked out from long distances.The latest Russian Yuri class ssbn left this double hull design if I'm not mistaken, any idea why?

going single propeller also requires installation of a larger propeller (also conforms the pressure on the propeller surface thus lowers noise) controllers on gears and propellers to operate in uneven conditons when the ship has surfaced. So these all points toward an advancement in technology, or a hand helping them out like the one was pointed by @Nilgiri
