Project 955: Borei class SSBN #2

What I like is this post from yesterday about the future submarine K-XXX Dmitry Donskoy which reads;

“The new Dmitry Donskoy submarine will be distinguished from the previous Borevs by a number of technical improvements that have been introduced by the developer of project 955A, TsKB MT Rubin. In particular, improvements will be made to the steam turbine plant, as a result, the boat propulsor will become even quieter,” said interlocutor of the agency on the sidelines of the International Maritime Defense Show (IMDS-2023).
He also clarified that in terms of its acoustic characteristics, the submarine will approach the multi-purpose submarines of the modernized project 885M (code "Yasen-M").


I can only imagine what a beast the project 885M submarine is..

Don't misunderstand me, because I think something similar to what you stated.
However, the submarine of project 955/955A that was built the fastest (from the laying of the keel to the active status) is the K-552 "Knyaz Oleg".
The keel for K-552 was laid on July 27, 2014, while it reached active status on December 21, 2021. So a little over 7 years.

Yes, so far the fastest Borey has been 7 years, but they have had a lot of work in the shipyards, including the Peter the Great which will be delivered soon and will free up a lot of workers to speed up the Boreys.
In the same piece of news that you have posted, there is talk of delivering the Dimitry Donskoy in 2026, which gives 5 years, I was also surprised when I read it, but if it is true, the series of 12 Borey's should be finished in 2030 and the next decade would be to start receiving the Husky's
It is not only reasonable but desirable, time will tell

Submarines rarely travel at full speed but even so the Yasen can cruise quietly at around 20 knots.

To MIR...


Yasen-M is twice as expensive as Borey-A and I don't think that's without reason.
Of course, there is no doubt that Borey submarines are very quiet.
And as for the data on "silent" underwater driving for any submarine, that data will remain unavailable to us.
There is that info that Yasen-M has quiet underwater navigation up to a speed of 20 knots, but the text was written in 2019 when NO Yasen-M submarines were operational yet. Some other information amounts to a much higher speed in silent mode, that is, up to 28 knots.
All that can be found on the internet is speculation and conjecture.
I'm sure the Yasen-M subs are beasts, thats all i know..

Very different roles... an SSBN will sail at relatively low speed to its operational area chosen to be in range of all its targets and there it will move around at very low speed... 2-4knts changing depths and directions and just trying to be lost.

Yasen is a hunter and might cover enormous distances looking for prey or looking at different places it might hunt prey in the future, or it might go spying near enemy waters and practise its ability to hunt using conventional shipping or enemy subs.

Zipping around at high speed all the time will just mean everyone knows where you are... moving at high speed might be to draw enemy subs away from some area, or there might be a place you have to get to in a hurry, but it attracts attention and gives the enemy somewhere to start looking for you so you don't just do it for fun or to show off.

KNYAZ OLEG.

Newly built SSBN «Imperator Alexander III» (Borei-II class) of the RuNAVY Pacific Fleet began sea-trials in the White Sea. It’s planned that the SSBN to be commissioned in this year.

Looks as if it sits on top of the silo and helps to load the missile. 


Yes, it does.
