    Knyaz Vladimir Project 955A submarine to join Northern Fleet


    The fourth submarine of the Project 955A, Knyaz Vladimir, is expected to join the navy by the end of 2019. It will remain with the Northern Fleet, joining the first Project 955 submarine, Yuri Dolgorukiy.

    Construction of Knyaz Vladimir began in 2012, it was floated out of the dry dock in November 2017.

    The fifth Project 955/955A submarine, Knyaz Oleg, still appears to be in the dry dock at Sevmash, although it was expected to begin service in 2020. It will join the Pacific Fleet.

    Compared to the first three Borei boats, inducted into the navy between 2013 and 2014, Borei-A boats are built with four additional missile tubes making them capable of carrying a total of 20 Bulava (RSM-56) ballistic missiles.

    Why do these so called experts keep claiming the Russians want 20 missile launch tubes in their Boreis?

    It made sense for Typhoon because there was no limit on how many SLBMs were allowed so if you had 6 boats then having 20 missiles in each... as opposed to say 12 or 16 meant you could have more missiles.

    These days the max number of missiles is limited so there is no value in putting all your eggs in fewer baskets.

    The current in force arms limitation treaty limits each side to about 1,500 warheads, which means if you divide that by three you are allowed 500 SLBM warheads... fitting 20 missiles into each borei with 6 warheads per missile means 500/6 = they can have about 83 missiles... with 20 missiles per sub that means four subs before they start having capacity for too many SLBMs. With 16 missiles per sub that means 5 subs... and 12 missiles per sub that means they can have about 7.

    If they declare each Bulava able to carry 4 warheads that means they can have 125 missiles, so with 20 missiles per sub that is about 6 subs, with 16 missiles that is about 8 subs and with 12 missiles that is about 10 subs.

    With 5 warheads per missile and 12 launch tubes you get 8.3 subs for 500 warheads... or more accurately with 5 warheads on each missile, with 8 subs with 12 warheads you get 480 warheads... which is about what they need. Replace a few of those 12 missile models with some 16 missile models and they will be close enough to 500... with the wording of the current treaty they only need to meet the numbers for one day anyway and when it expires the next day they can make as many as they like.

    START expires in 2021. If there is no new START there will be no limits. That is why Putin is very afraid of the US leaving START. The USA has a lot of MIRV W-76 warheads in stock. It can very quickly increase its nuclear potential. Trident II transfers to 14 MIRV Mace to 6 MIRV with Throw Weight 3 times smaller than Trident II.After 2021, there will probably be no warhead limits. USA wants to withdraw from START

    So what if it does withdraw from new Start... making nuclear weapons is much cheaper than maintaining a very large conventional force.

    I rather suspect considering all the new weapons they describe as doomsday weapons... like Posiden, and that nuclear powered cruise missile, that they will also be working on ever more powerful warheads to match.

    Their work on miniaturising warheads should lead to improvements... a cruise missile with unlimited flight range might originally have had a 400Kt nuclear warhead, but as a doomsday device they could take that warhead out and replace it with a dozen or more tiny 2kt nukes that can be dropped as the missile flys along its way.

    Their new design fast breeder reactors should be ideal for making weapons grade material very quickly too, so any new Arms race the US wants to start... Russia will be happy to oblige I am sure.

    I doubt Putin thinks Trump is smart enough to renew the new START programme... it wasn't really the number limitations... it was the right of inspections and trading information that made it valuable... with no replacement for New START the Russians can do what they like and not have to declare anything at all to the west.

    Those hypersonic Zircons and upgraded 3,500km range hypersonic Iskanders might have nuke payloads or they might not.

    From recollection US actually shut down their Plutonium breeder like 20yrs ago...

    But they've been many years behind on treaty obligations to permanently destroy a bunch of Plutonium, never even got round to starting building the facility vs Russia not just built their facility but finished 'burning' (as in used it to generate electricity) all the Plutonium they were supposed to several years back.

    They'll still claim Russia failed to comply, that US has completely complied & its definitely Russia to blame for no START renewal, western bravely independant media will repeat that line without any evidence or questioning until everyone assumes its true dunno

    Russian latest Borei-A nuclear-powered sub completes state trials


    The most advanced nuclear-powered submarine Knyaz Vladimir has arrived at the Northern Fleet’s Belomorsk naval base


    MOSCOW, November 21. /TASS/. The most advanced nuclear-powered submarine Knyaz Vladimir (Prince Vladimir) has completed the cycle of state trials and arrived at the Northern Fleet’s Belomorsk naval base, the Fleet’s press office reported on Thursday.

    "The latest Project Borei-A strategic underwater cruiser Knyaz Vladimir has completed state trials at the Northern Fleet’s combat training ranges in the White Sea and arrived in Severodvinsk," the press office said in a statement.

    At the wharf of the Northern Fleet’s Belomorsk naval base, the cruiser’s crew was welcomed by Base Commander Rear Admiral Konstantin Kabantsov and CEO of the Sevmash Shipyard (part of the United Shipbuilding Corporation) Mikhail Budnichenko.

    On October 30, the crew of the Knyaz Vladimir test-fired a sea-launched Bulava intercontinental ballistic missile from the White Sea towards the Kura range in Kamchatka in the Russian Far East and also held torpedo fire against an underwater and surface target.

    Aside from the trials of the sub’s sea-launched weapons, the shipbuilders checked the operation and the reliability of all its systems, mechanisms and equipment and made measurements of the noise level and the underwater cruiser’s other special parameters.

    The Knyaz Vladimir is the improved Project 955A strategic missile-carrying underwater cruiser and represents the fourth generation of nuclear-powered subs built for the Russian Navy.

    Compared to the first three Borei-class submarines - the Yuri Dolgoruky, the Alexander Nevsky and the Vladimir Monomakh, the Knyaz Vladimir is less noisy and features improved maneuvering, depth and armament control systems.

    Source: two submarines Borey-A laid on the day of the 75th anniversary of Victory (9 may 2020) russia russia attack

    MOSCOW, Nov 29 - RIA Novosti. The ninth and tenth nuclear submarines of the modernized project 955A (Borey-A) are planned to be laid down on May 9, 2020 and transferred to the Russian Navy in 2026 and 2027, a source in the military-industrial complex told RIA Novosti .
    "The laying of the ninth and tenth Borea is scheduled for May 9, 2020. The transfer to the Navy is in 2026 and 2027," the source said.

    The source noted that the names for the new submarines have not yet been determined.

    Earlier, Deputy Minister of Defense of the Russian Federation Alexei Krivoruchko told reporters that the Ministry of Defense had planned to supply the Navy with two nuclear submarines of Project 885M (Yasen-M) and two nuclear missile carriers 955A (Borey-A). Thus, the number of "Boreev" will be increased from 8 to 10 submarines.
    Three Boreas have already been built and are part of the fleet: Yuri Dolgoruky, Alexander Nevsky and Vladimir Monomakh. The fourth submarine, "Prince Vladimir," is undergoing sea trials.

    That would be 10 Boreis and 9 Yasens

    Hopefully they keep at it, it's nice too see the fleet going into double digits for a change without constant flip-flopping and starting over from scratch

    Thanks thumbsup It's way more difficult to put all the news that keeps this forum going(George1). Or give great explanations like Gazputin, GarryB, etc...and of course the giant Mindstorm...oh and Arrow too for the laughs.

    I think when a product is working keep buying, the r&d for the new SSBN can wait a little, the problem is when they buy like Lada submarines etc...

    The 24 tubes of the Ohio class and 20 tubes of the Akula class were from a time when there were no restrictions on how many missiles or warheads you could have so having more on each sub just meant for every new sub you put in to service meant more missiles available for use if needed.

    These days with new START.... right now Russia could have 2 and a half Akulas with 500 warheads in 50 missiles, while the US could have 3 and a half Ohios with 504 warheads in 84 missiles.

    With Borei having 16 launch tubes and 6 warheads per missile that is 96 warheads per boat so just over 5 Boreis is legal these days.
