    So 7 is not the final amount? 7 is kind of a strange number anyway... Why not 6 or 8? I know they are going to have another class to replace most older SSNs and/or they can order more Yasens like after 2025, but just wondering...

    I'm manufacturing guy, and as it seems they already started to manufacture the sixth new boat when they realised how mindblowingly expensive they are.

    SEVERODVINSK, March 31. /TASS/. Another multipurpose nuclear-powered submarine Kazan has been launched at the Sevmash shipyards, a TASS correspondent reports from the scene of the event.

    Clearly no pump jet or propulsor ducts then...  My guess is that the Russians don't want their SSNs to be hampered with the performance penalties that pump jets impose, and/or don't think they are worth the cost?

    I'll be interested in seeing more of her hull and the build quality.  To my eye, the Severodvinsk looked a little rough in patchs, no doubt due to her...  shall we say...  prolonged gestation....

    Pump jets must be yet another example of "superior" US technology that stupid Russians can't match.

    I can see a good reason for not using them: they are a sound resonance box. The last thing Russian engineers would
    want is for some harmonics of the propeller noise to be boosted for the pleasure of American sonars.

    If Russia can afford to blow a few tens of billions on Banderastan, it can afford a few billion on submarines vital for its survival.
    And as we have seen with the Project 636.3 boats, Russian prices are a small fraction of what Yankees and Brits shell out for
    their subs.

    The might of Russia's advanced nuclear submarine

    Russia's armament program through 2020 envisages the construction of six new Yasen-class submarines, armed with eight vertical silos for cruise missiles and ten torpedo tubes

    TASS-FACTBOX. March 31, 2017. The Sevmash Shipyard in Severodvinsk in northern Russia has floated out the second Project 885 Yasen-class nuclear submarine Kazan.

    The Project 885 (08850) Yasen-class fourth-generation multipurpose nuclear submarine was developed in the 1990s by the St. Petersburg-based Malakhit Design Bureau of Maritime Machine-Building under the direction of Chief Designer Vladimir Popov. The submarine is based on the Projects 705(K) Lira and 971 Shchuka-B. Sevmash, which is located in Severodvinsk in the Arkhangelsk Region and is part of the United Ship-Building Corporation, is the shipyard engaged in the construction of Yasen-class submarines.

    The Project 885 Yasen-class submarine is designed to destroy an enemy’s submarines and surface ships, naval bases, ports, naval task forces and other targets. The Yasen-class submarine’s one-and-a-half hull design (the outer hull giving the submarine its streamlined shape is present only in its forepart).

    Submarine’s performance characteristics

    According to public sources, the Project 885 submarine is about 139 meters long and about 13 meters wide and has a draft of 10 meters. The submarine displaces 8,600 tonnes in its surface position and up to 13,800 tonnes in its underwater position. It can submerge to a maximum depth of 600 meters and develops a speed of 16 knots in its surface position and up to 31 knots in its underwater position. The submarine has a sea endurance of 100 days and a crew of 85-90 men. It is equipped with a single-shaft steam turbine nuclear power unit with a capacity of about 43,000 hp. The submarine’s OK-650V water-cooled and water-moderated reactor has a thermal capacity of 190 MW (modernized Project 885M submarines will be outfitted with a power unit of over 200 MW).

    The Project 885 submarine is armed with eight vertical silos for Oniks and Kalibr cruise missiles, ten 533mm torpedo tubes with an ammunition load of 30 torpedoes each. Submarines of this type can be eventually armed with new Kh-101 (Kh-102) cruise missiles and universal deep-water homing torpedoes.

    Submarine series

    The Project 885 lead submarine K-560 Severodvinsk (Factory No. 160) was laid down at the Sevmash Shipyard on December 21, 1993, floated out on June 15, 2010, delivered to the Russian Navy for operational evaluation on December 30, 2013 and made operational in the Northern Fleet on June 17, 2014.

    The other submarines of this series are being built under the modernized Project 885M (08851) Yasen-M. They are characterized by the optimized hull shape and upgraded electronic warfare and automation systems.

    A contract for the construction of a submarine with Factory No. 161 was signed between Russia’s Defense Ministry and the Sevmash Shipyard on December 6, 2005. The construction of five submarines of this series with Factory Nos. 162-166 is stipulated by a contract of November 9, 2011 concluded with the United Ship-Building Corporation.


    •    The second submarine, the K-561 Kazan (Factory No. 161), was laid down on July 24, 2009, floated out on March 31, 2017 and is expected to be delivered to the Russian Navy in 2018.


    •    The third submarine, the K-573 Novosibirsk (Factory No. 162), was laid down on July 26, 2013 and is scheduled to be delivered to the Navy in December 2019.


    •    The fourth submarine, the K-571 Krasnoyarsk (Factory No. 163), was laid down on July 27, 2014 and is expected to be delivered to the Navy in December 2020.


    •    The fifth submarine, the K-564 Arkhangelsk (Factory No. 164), was laid down on March 19, 2015 and is expected to be delivered to the Navy in December 2021.


    •    The sixth submarine Perm (Factory No. 165) was laid down on July 29, 2016 and is expected to be delivered to the Navy in December 2022.


    The state armament program through 2020 envisages the construction of six Yasen-class submarines. Another underwater cruiser, the Ulyanovsk (Factory No. 166), is expected to be laid down in July 2017 and delivered to the Navy in 2023.

    The kazan should have ten VLS and eight tube by wiki.

    The 8* VLS 'silos' are big tubes with 4 missiles each.
    Presumably similar to how UKSK has tubes in the lower part

    So it's 8*4 = 32 VLS missiles (wiki says 8*4 = 32 Onyx or 8*5 = 40 Kalibr but may be mixing up Kazan having 10*4 = 40?)

    Bit disappointed this 'launch' seems to have actually been only a Christening since there is no sign of it going in the water (where pics might confirm Kazan having 10*4 VLS).

    Was wondering if they'd have to pause work on Nakhimov but it looks like they built up that side of the basin.

    The picture above showing two large tubes with 8 hatches is the UKSK launcher as fitted to surface vessels.

    It carrys Onyx and Calibr and Brahmos already and each launcher carries 8 missiles.

    If it has 8 VLS then it would have the capacity for 64 missiles as each VLS system carrys 8 missiles.

    The nameplates look like they still have 4 caps on each side. Maybe they mean torpedo tube launched Kaliber?

    Yes my point was to illustrate that the surface 8-cell UKSK module is split in the bottom into 2 tubes with 4 missiles each.

    So any thoughts on the rumor that Kazan is 10m shorter than Severodvinsk?
    Would seem to militate against the extra VLS its supposed to have.
    But supposedly smaller crew also -> more automation -> could it be smaller as well as having more missiles? confused

    Both Onyx & Kalibr (from the Gepard) in this

    And this

    A slowmo Brahmos launch https://gfycat.com/SecondLimpingAntarcticfurseal

    I'd call it a pretty hot launch.

    Edit: Charly015 on Severodvinsk vs Kazan length http://charly015.blogspot.co.nz/2017/05/sobre-precio-dimensiones-y-la.html
    Sail & tailfins seem same distance apart

    But Kazan bow seems to be shorter

    The Kazan is a new submarine, the Severodvinskvs is manufactured in the 90s.

    Maybe they changed the specifications for the amount /type of the torpedoes.

    It is not the sonar?

    There was same talk about to replace the cylindrical one with spherical one.

    Yeah Severodvinsk has a spherical sonar -> the torps are midships like on US Subs.

    Edit: Presumably Kazan has too, not seen any suggestion that its changed back to cylindrical.

    I suspect that the reduced length of the bow may be related to the revised/modernised (ie smaller) equipment design and improved automation to reduce the boats complement?  The diagram below suggests that the control room occupies the forward section, which may now be smaller with increased systems automation.  If the living quarters is also reduced, it could result in torpedo storage/handling being shifted aftwards, thus shortening the boat?

    Not a definative source regarding the 855 internals, but it does support conjecture.
