What is clear there, is a fact that English speaking audience is retarded en masse. And filled with shit.
To be fair as part of that English speaking audience I would say many do just go with the flow and are not prepared to go against the widely accepted views of western propaganda and that a few that are trying to sell the propaganda message of the west tend to be very vocal and seem to have plenty of time to share their thoughts.
Honestly I have noticed a vast increase of westerners going to YT channels like Indian news channels to find unbiased news regarding BRICS and Ukraine and even Israel and celebrating Russia and China and other countries of the south for standing up to the colonial west.
Recent elections in the west seem to confirm a real shift of people no longer believing the narrative and the propaganda, but of course it will take rather more than that to deal with the monster...
They can't make any reasonable analysis because that shit is coming out of any single case.
If they start thinking about the truth the whole rainbow structure falls down so they just take the pieces of the puzzle they are given and make the picture on the box and tell how obvious and easy a jigsaw puzzle is when there are only three pieces...
Putin bad, Russia bad, West good.
Bad means always at fault and always meddling, and good means never bad and never wrong.
It is an end effect of wide spread and massive propaganda that starts from an early age and surrounds people there for their entire lives.
Opportunities to make a good living dry up very quickly if you pick the wrong path.
It is not the end. Kazan can go to a depth of 600m, if not more, and is much more automated.
The only thing we don't know is what about the acoustic signature, but we won't find out about it.
Another factor is that the US was making its subs out of non spec steel, so parts of their subs could fail unexpectedly when put under stress...
Screw noise is dealt with its shape, and no matter what the Angloids will say, it is just a matter of mathematics.
To be fair the propellers are enormous and being able to make them to the precision level where the mathematics gives you an advantage is a core feature of getting your sub quiet.
Of course wasn't it five or six axis milling machines from Japan that raised their game in the 1980s and led to a dramatic improvement in performance... or is that just a myth?
If you have a double hull structure, it means that not only every system can be isolated from the hull with different sort of absorption pads, but you have it all isolated from the external hull. It is spaced, with an additional layer of water that can be used as an additional silencer.
Anybody who has been in a music room at school or a sound recording studio will notice the material on the walls to absorb and reduce sound... with a double hull you can have extra spaced layers of sound reducing material including rubber like material on the outer surface to reduce the effectiveness of enemy active sonar pings too.
Second to that, Soviet subs carried more advanced, longer ranged, and much more versatile ordnance.
Even looking at the propaganda, in the 1970s the US had Harpoon and Tomahawk, while the Soviets had a wide range of anti ship cruise missiles of all shapes and sizes and performance levels.
