    Submarines 955A have the highest priority because they are part of the nuclear triad. Soon Russia will have the most modern naval nuclear triad in the world. More modern than the American one, which has always been the basis of American nuclear power. Modern 955A's are probably quiet enough to sail out into the wide oceans unnoticed, although the Russians probably do patrols on the Barents Sea, etc.

    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..

    He is surely joking. A pumpjet submarine which usually travels at slow speed like the Borei-A should be way, way quieter than an attack submarine with a conventional propeller like the Yasen-M.

    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...

    thumbsup
    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.

    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.

    Interesting anyone know what it could be. Looks like it's being loaded into a missile silo.

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

    Right is probably used to catch a ballistic missile. This is after Bulava is loaded

    See how Bulava is accelerating quickly? It seems to do this much faster than other SLBMs?

    "Arsenal of the Fatherland": Borey submarines "hear" underwater further than US submarines

    Project 955: Borei class SSBN #2 - Page 4 15519111

    MOSCOW, November 16 – RIA Novosti. Russian strategic nuclear submarines "Borey" with their hydroacoustic station "hear" under water 1.5 times further than American submarines, according to an article in the new issue of Arsenal of the Fatherland magazine.

    “One of the innovative means of superiority of the Borei class submarine cruisers is the hydroacoustic complex, which allows you to detect (“hear”) enemy ships at a distance one and a half times greater than similar systems of the most advanced American fourth-generation Virginia-class multi-purpose nuclear submarines, not to mention Ohio-class SSBN,” notes the publication authored by 1st Rank Captains Vitaly Bychkov and Vladimir Semiletov, employees of the Naval Institute VUNTS Navy “VMA”.

    As the editor-in-chief of Arsenal of the Fatherland, Viktor Murakhovsky, clarified to RIA Novosti, “in terms of detection range, the Borea sonar system exceeds US nuclear strategic submarines by about 100 kilometers.”

    He clarified that the Borei submarines are equipped with the Irtysh-Amphora-B-055 sonar system, which can simultaneously track at least 30 underwater targets.
    The complex includes the main hydroacoustic antenna "Amphora" with digital signal processing, as well as large-area side antennas and a towed antenna. "Irtysh-Amphora-B‑055" can operate in noise direction finding, echo direction finding and target classification modes. In addition to detecting submarines, torpedoes, mines and other underwater weapons of the enemy, the complex allows you to measure the thickness of ice in the Arctic regions, detect openings for surfacing or launching ballistic missiles.

    Strategic missile cruisers of projects 955 "Borey" and the modernized 955A "Borey-A" belong to the fourth generation of missile submarines. They are armed with 16 Bulava ballistic missiles and are designed to solve strategic nuclear deterrence tasks.
    The Navy's operational strength currently includes six Project 955 and 955A submarines: "Yuri Dolgorukiy", "Alexander Nevsky", "Vladimir Monomakh" of Project 955 and "Knyaz Vladimir", "Knyaz Oleg" and "Generalissimus Suvorov" of Project 955A.

    Three 955A boats are being built at the Sevmash enterprise: “Knyaz Pozharsky”, “Dmitry Donskoy” and “Knyaz Potemkin”. Another "Borey-A" - "Imperator Alexander III" - was launched in December 2022 and is now undergoing state tests. By the end of 2024, the cruiser should be part of the Pacific Fleet.

    Source: in 2024, two nuclear-powered cruisers of the Borei-AM project will be laid down at Sevmash

    Taking into account the Boreevs already built and under construction, it is planned that the Northern and Pacific fleets will each have six such cruisers this decade, the agency’s interlocutor added

    MOSCOW, March 27. /TASS/. Two nuclear submarine strategic missile cruisers of the modernized Project 955AM "Borey-AM" will be laid down in 2024 at the Sevmash enterprise for the Northern and Pacific fleets. A source in the military-industrial complex reported this to TASS.

    “This year, two nuclear cruiser of the modernized Project 955AM Borei-AM will be laid down for the Northern and Pacific fleets. All of them were contracted in 2021,” the agency’s interlocutor said.

    He noted that taking into account the Boreys already built and under construction, it is planned that the Northern and Pacific fleets will each have six such cruisers this decade. TASS does not have official confirmation of this information.

    When you figure out a good thing you commit and keep spamming them until your needs are covered and you have a buffer to work out the potential replacement at leisurely pace

    Yes but since russian navy is way smaller than US navy and focuses on its border waters it can't patrol all the oceans.

    US subs are quite safe even if older and noisier.

    On the opposite the US aand chiwawa states keep getting closer to russian bases and can focus there to wat h for russian navy.

    Russia need to build much more Yasen and a new cheaper SSN.

    Same is true for China.
