    The 8* VLS 'silos' are big tubes with 4 missiles each.
    Presumably similar to how UKSK has tubes in the lower part
    Project 885: Yasen class - Page 19 3p-14uksk_ris_011
    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
    Project 885: Yasen class - Page 19 885m%2Bdiferencias%2B2
    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.

    To reduce the length of the new cruise missile sub, the Russians removed frames from multiple compartments. http://www.hisutton.com/Pr885_Analysis.html … #OSINT

    The nuclear submarine cruiser "Ulyanovsk"

    On July 28, 2017, in the shop number 55 of the JSC "Production Association" Northern Machine Building Enterprise "(SMP, is a member of the United Shipbuilding Corporation) in Severodvinsk, the ceremony of laying down for the Russian Navy a multi-purpose nuclear submarine cruiser Ulyanovsk (Serial number 166) - the sixth in the series of the ship project 08851 (the same 855M). The project was developed by JSC "St. Petersburg Marine Bureau of Mechanical Engineering "Malachite". Vice-Admiral Viktor Bursuk, Deputy Commander-in-Chief of the Russian Navy, took part in the ceremony.

    Project 885: Yasen class - Page 19 4502831_original

    The main nuclear submarine cruiser of the project 885 series (code "Yasen") K-560 Severodvinsk (plant number 160) was laid on the NSR on December 21, 1993 and transferred to the Russian Navy for trial operation on June 17, 2014. Further construction of the series is carried out on the SMP on the modernized project 08851 (code "Yasen-M"), which laid the nuclear submarines K-561 "Kazan" (plant number 161, laid on the NSR on July 24, 2009, March 2017 and launched on April 8, 2017), K-573 "Novosibirsk" (plant number 162, incorporated on July 26, 2013), K-571 "Krasnoyarsk" (plant number 163, incorporated on July 27, 2014), K -564 Arkhangelsk (plant number 164, laid March 19, 2015) and Perm (plant number 166, laid down on July 29, 2016).

    "Ulyanovsk" became the fifth and the last ship, built in the framework of the contract S/1/2/0618/GK-11-DGOZ, concluded on November 9, 2011 by the Ministry of Defense of Russia with United Shipbuilding Corporation OJSC for the construction of five serial nuclear submarines of the project 885M ("Ash-M") with the factory numbers 162, 163, 164, 165 and 166.

    Wait Does the Yasen-M carry 8 UKSK sets or 10?

    Because most reliable sources claim 8....
    the ones that claim 10 are dubious sources....

    Does anyone have info about this?

    10 but it carries only 8 torp launchers.

    that is what I have seen from Naval documents.

    8 x VLS equipped silos for either:
    32 (8 x 4) with Oniks, or
    40 (8 x 5) with Kalibr-PL anti-ship, anti-submarine and land attack submarine launched weapon. Kh-101 cruise missiles.
    10 × torpedo tubes (8x650mm and 2x533mm).

    Yasen-M Class (Pr. 885M)
    10 x VLS
    8 x torpedo tubes (6x650mm and 2x533mm)

    Can anyone say what was the reason behind length reduction?

    Usually upgraded versions grow in size.

    A shorter hull radiates less in the longer wavelength range. Think of the hull as a flexing tube. Just like with centrifuges there
    are all sorts of modes of vibration, including flexing along the major length axis. Longer wavelength waves generated by
    this flexing in the ambient water medium will propagate farther and be more easily detected by the enemy.

    If they can make it shorter and get the same job done, then they are showing that they have a clue.
