    The three parallel holes in the starboard and port bow section above waterline look interesting. Just hatches for ballast water or perhaps they could have something to do with countermeasures.

    The SSBN is a strategic asset, putting it at risk of discovery to operate in a conventional role is not something we want to be doing with the guaranteeor of our sovereignty. It's job is to remain undiscovered so it can play the deterrent role it serves.

    Yes, I totally agree... but this was at a time in the 1990s when some on the internet suggested Russia was over as a military power and that there would be no more funding for anything... even speculation that when NATO took on F-35s that they might sell Russia their old F-16s because Russian fighter design bureaus could not survive... they had lost their eastern europe market for selling fighters and the Russian military couldn't afford to buy many... looking back now it seems silly, but at the time most of the new stuff now like Pantsir and other things were just marketing shells... they had Mi-28Ns in pictures but the guts of the aircraft wasn't developed... they were flying early prototypes.

    Of course looking at the issue today you could actually follow through with the idea in a clever way that eliminates the issues you mentioned... if every modern sub is fitted with two external launch tubes with the nuclear propelled unlimited range cruise missiles, then in effect every sub could launch a strategic nuclear strike on any target on the planet... so even if HATO managed to destroy several SSBNs targets will still get destroyed eventually.

    For those unaware, modern subs have internal and external launch tubes... the difference is that internal ones can be reloaded from inside the sub, while external launch tubes don't hang on the outside of the hull, they are normally located between the inner and outer hull of the sub so they are always loaded and ready to fire, but cannot be reloaded... UKSK launch tubes are an example of external tubes, but there are lots of decoy and jammer and anti torpedo tubes on subs that allows things to be launched rapidly 24/7.

    The 955A looks much more advanced than the origianl 955...
    And Russians still call them 955 just like the case of 11711, you see Rassians do have some odd taste of humour...

    Original Borei has them too, but the 955A has them in slightly different positions. Hardly surprising given the change in hull design (original 955 used hull sections from unfinished 971s)

    Meh... 17 mins of my life I won't get back.....

    Obsolete info given the author thinks the main differences between 955 and 955A is the all-moving tailplane. In reality, a 955A is as similar to a 955 as a Ohio is to a Delta IV.

    The BS about sonar signatures of the 955 is simply a joke. We are supposed to believe that genuine info from the USN regarding Borei acoustic characteristics is going to be public domain??? J fecking C... this guy is simply disseminating disinfo from "unclassified" sources that are little more than conduits of US fakery.

    Amusing, but the guy can't even count... he said the Bulava can carry 6 warheads and 40 decoys, so the target would see 46 incoming warheads of which only 6 would go boom.

    Pumps designed to be easily replaced not being replaced in peace time... big deal.

    And now not humped: Atomic bomber carriers change appearance for the sake of speed and noiselessness

    New submarine received a unique profile


    Strategic nuclear missile carriers of the Project 955 "Borey" got a new look. The first updated boat was the "Prince Vladimir", the tests of which are now coming to an end. According to Izvestiya sources in the military department, the superstructure was altered on the nuclear-powered icebreaker, the bows of the bow became more streamlined, but the main thing was that the hump of the rocket launch platform disappeared. Such changes improve the driving performance of Prince Vladimir, as well as increase its noiselessness when driving under water. It is possible that the transformation of Project 955 boats will continue.

    The appearance of the first "Boreya-A" is fundamentally different from its predecessors "Yuri Dolgoruky", "Alexander Nevsky" and "Vladimir Monomakh." The first thing that catches your eye is the absence of the so-called rocket launch platform for the Prince Vladimir. There are no characteristic protrusions in front of the cabin, in which the acoustic systems of the first Boreev are supposedly installed. In addition, the contours of the bow of the ship have become more streamlined.

    Changed and the appearance of the add-in. The first "Boreev" she was beveled: its front part, when viewed from the side, closer to the deck narrowed. At Prince Vladimir, the cutting area received a traditional profile.

    I've been thinking: is it possible that Russia is sitting on Borei-K SSGN project because they are waiting for START treaty for fizzle out before starting construction to avoid needless bad PR?

    I know that it's not in contradicton to the treaty and that USA is already operating Ohio SSBNs but I would 100% expect USA to use it as one of excuses to pin the blame for treaty getting scraped on Russia.

    Waiting several months before ordering them would cost them nothing and USA would have one less possible excuse for letting START expire.

    Don't you mean the Borei-K SSGN project... and you answer it yourself... the US does not want to sign it to renew it so they wont... any excuse they use would never be the real reasons anyway and whether they can justify it or not they wont be signing a new agreement any time soon so who cares what reasons they use.

    I rather suspect they want to include hypersonic weapons in both a replacement for the INF treaty and the New New START treaty... and I hope the Russians wont give up that... I am also sure the US will demand China be included but wont demand the UK or France be included too... including France and or China would mean no change of an agreement... why would they give up anything when the US and Russia have so many more much more powerful weapons?

    Source: the head "Borey-A" "Prince Vladimir" at the end of June will resume running trials

    TASS interviewer confirmed that the missile carrier will serve in the Northern Fleet

    MOSCOW, June 14. / Tass /. Strategic missile cruiser “Prince Vladimir” of Project 955A (code “Borey-A”) at the end of June 2019 will go to sea to the second stage of factory trials. About this TASS reported a source in the military-industrial complex of the Russian Federation.

    “After the measurement of magnetic electric fields at the berth wall of Sevmash, Prince Vladimir will be released into the sea at the end of June to pass the second stage of the factory test run (ZHI), which will last several months,” the agency’s source said.

    He recalled that "Prince Vladimir" first went to sea at the first stage of the ZHI at the end of November 2018 and returned to Sevmash at the beginning of January 2019.

    "During the tests, some technical problems emerged, which, however, should not affect the delivery of the ship to the fleet at the end of 2019," said the source and confirmed that the missile carrier would serve in the Northern Fleet.

    Those April pics have it sitting much lower in the stern, bow up & I think generally lower.
    These new pics show it more properly as a direct variant of the original Boreis.

    Source: Russian Defense Ministry and USC will sign a contract for two more Boreas and two Yasen-Mattack

    The construction of four ships is expected to begin within the framework of the state armament program until 2027.



    "At the Army-2019 forum, it is planned to sign a contract of the Ministry of Defense with USC to build two more Boreev-A and two Yaseni-M in addition to the already contracted submarines of these types," the agency’s source said. He added that "the construction of four ships will begin as part of the state armament program until 2027, but they will be handed over to the fleet after it is completed."

    The construction of the Boreyev and Ash-m for the Russian Navy is being conducted by the defense shipyard Sevmash. In accordance with the state armament program, designed for the period up to 2027, eight Boreans and seven Ash trees should be built and transferred to the fleet. To date, there are three Boreas of the basic project 955 (Yuri Dolgoruky, Alexander Nevsky and Vladimir Monomakh) in the naval squadron and one Project 855 Yasen (Severodvinsk). The head submarines of the upgraded projects 955A "Prince Vladimir" and 885M "Kazan" were built and are at the stage of factory trials.

    2 more Yasen-M is surprising.

    2 Yasens is a very happy news, indeed!

    Still not enough tho.

    Boreis are really coming along just fine.

    Russia to complete Borei and Yasen series of nuclear-powered submarines in 2023-2024

    KUBINKA /Moscow Region/, June 27. /TASS/. Russia will complete the Borei/Borei-A series of nuclear-powered underwater strategic missile-carrying cruisers in 2023 and Yasen/Yasen-M nuclear-powered multirole subs in 2024, Sevmash Shipyard CEO Mikhail Budnichenko told TASS at the Army-2019 international military and technical forum on Thursday.

    What a pointless statement...

    What are​ they saying here exactly?

    That they will not cancel ships currently under construction? That they will finish only ones currently laid down? That they will complete​ all planned ships including ones not yet laid down?

    Should have just kept his mouth shut.

    I think they're saying with the special purpose subs & 'first serial' Borei-A/Yasen-M done they can focus efforts & build serial boats quicker?

    Looking at the HI Sutton drawing above with absent flank arrays & recent suggestion that Yasen-M has a Lada style conformal array, might Borei-A have same? (or modular variant)

    Makes sense to share that same tech on both types.
    Bow torps on the Borei-Adoesn't preclude the conformal array since Lada has bow torps but might mean a somewhat different setup than on the Yasen-M.

    Don't understand your point. They are saying WHEN the current submarines being built will be completed.

    At the same time, the construction of nuclear submarines such as "Borey-K" is not planned

    Their cruise missile armed subs will be used in conventional war so they don't need to be state of the art super stealthy... the vast majority of the countries on the planet couldn't track down a Foxtrot off their coast let alone a more modern sub like a Delta IV which could carry cruise missiles in two stacks or one stack with a greatly reduced hump size....
