    Here is your pool. You can find the entire documentry on the net. I think it was called mission invisible (at least the french title was Something like that).

    You're welcome.

    Better with the sound turned off...

    They get a dollar a month.... and where are they going to spend that dollar?

    Food and lodgings are provided.... they don't have to pay for anything... Geez I hate US documentaries.

    Regarding the two libraries I seem to remember mention that one was for officers and was technical books and the other was for everyone and included comic books and general literature.

    Charly015 comparison http://charly015.blogspot.co.nz/2017/11/el-submarino-knyaz-vladimir-se-botara.html
    As well as the rudder, towed array & T on the horizontal stabilisers the hump is missing/shorter

    Also but not mentioned by him this shot shows clearly the stern is tapered considerably more steeply.

    Gonna be interesting to see full length pics.

    What about the number of launchers? 16 or 20 ? Not many photos.

    -What are these doors?
    ~Those doors, sir, are the problem. I-I don't know what they are, neither do the British. Perhaps our friends in Murmansk have come up with something new.

    Speaking of full length pictures where the hell are they, I need those!!! cry

    Also, can someone explain to me where that "towed array" fits? It's can't be that little hole on the stabilizer, it's too small, isn't it? Or not?

    Teach me!

    Look at the Charly015 pic again.
    The older 955 has towed array off the top of the fin, diameter looks about the same (almost certainly exactly same)
    Also compare the visible hole with the size of the ppl nearly directly below, the hole must be something like 600mm diameter.
    Cables themselves are only something like 10cm diameter afaik.

    The steeper inclination of the stern could be to alow for more missiles or other equipment to fit in the submarine by alowing you to locate the drive system further towards the rear. Does anyone know how many missiles it carries?

    No.

    They are making 8 Boreis... if they put 20 missiles in the damn things then 160 missiles with.

    Bulavas are described as SLBMs with 6-10 warheads per missile... do the maths.

    Assuming 6 warheads per missile and 16 missiles per boat that is 768 warheads.

    Assuming 10 warheads per missile and 20 missiles per boat that is 1600 warheads.

    A little hint... the new Start treaty limits each side to 1200-1500 warheads each, which means about 400 warheads per branch of the nuclear triad, so even with 16 launch tubes they will be carrying more like 3-4 warheads per missile in their subs.

    20 launcher is better option. You can quickly increase your strategic arsenal. The USA has much more launchers in SLBM and ICBM.
    Russia has no money for many SSBNs. Borey A with 16 launchers is a big mistake.

    So Borey-A has 16 launcher or 20? Any photo ?

    Borei-B has 20 SLBMs.

    Who said it has 16?

    I think too that, dimensions-wise, those devices on the horizontal rudder could house a trailed sonar or whatever device.

    About hull forms, if I'm right that is the first hull built from scratch.

    So the exception should be considered the first hulls, built around sections meant for older vessels, not this one.

    At last. about the doors, some of them are likely just seacocks. I.e. valves ingesting sea water for any possible need, from desalinization to cooling, up to ballast tanks filling and discharging.

    I think it is likely that every single function has its own seacock's design, engineered specifically to perform a single specific duty, discretion being the first and foremost requirement in a SSBN.

    Well all sources I have seen about the 955A(U) has said that the submarine will carry 20 SLBMS. I gess we soon will find out.

    Oh, I know, probably for reactor coolant water.
    But you know, big new Russian missile sub with some unusual doors, what more perfect opportunity is there for using that quote jocolor

    Maybe, maybe not, no photos available yet.

    Still speculative since no full images have surfaced.

    START treaty is a hassle but if they get the production speed right it won't hurt to have more subs with fewer missiles from strategic standpoint.

    Wait and see.

    Details about the nuclear submarine cruiser "Knyaz Vladimir"

    The well-known resource "Covert Shores" very quickly issued its analysis on the main nuclear submarine missile cruiser of strategic design 09552 "Prince Vladimir", withdrawn from the shed JSC "Production Association" Northern Machine Building Enterprise "on November 17, 2017. Authors of the resource analyzed the available photo and video images and came to a number of conclusions.


    We only note that, according to unofficial information, the fencing of the retractable devices of the new SSBN is somewhat different from the one cited in the diagram (c) hisutton.com


    The authors of the resource counted 16 missile silos on the boat, which refutes earlier assumptions that the upgraded SSBNs will carry 20 submarine-launched ballistic missiles (SLBMs) ​​(with) hisutton.com


    The official designation of the main nuclear submarine strategic missile cruiser Knyaz Vladimir (plant number 204) of the modified project 955A (project 09552, code Borey-A) was made at the Northern Sea Route in Severodvinsk on July 30, The construction is carried out under a separate contract between USC and the Ministry of Defense of Russia N / 1/2/0368 / GK-12-DGOZ dated May 25, 2012. The actual building of the ship is being carried out on the NSR since 2009.

    Also on May 25, 2012, the Ministry of Defense of Russia with USC for the construction of four serial ARPKSNS project 955A (09552, "Borey-A") with factory numbers 205 , 206, 207 and 208, now the construction of serial ships of this project "Prince Oleg" (serial number 205, officially laid July 27, 2014), "Generalissimo Suvorov" (plant number 206, laid down on December 26, 2014 ), "Emperor Alexander III" (serial number 207, laid December 18, 2015) and "Prince Pozharsky" (factory number 208, incorporated on December 23, 2016).

    Earlier, the SMP carried out the construction and transferred to the Russian Navy the first three project 955 (09551, Borey) - K-535 Yuri Dolgoruky (plant number 201, transferred to the Russian Navy on January 10, 2013), K-550 Alexander Nevsky plant number 202, transferred to the Russian Navy on December 23, 2013) and K-551 "Vladimir Monomakh" (serial number 203, transferred to the Russian Navy on December 19, 2014).

    So the Borei has fewer missiles than the Ohio, and there are far fewer Boreis than the Ohios. Are there any really definitive advantages to the Ohio, apart from vague "next generation" explanations? I know everything is top secret, but can there be an educated guess? Can we expect the Borei to be multiple times quieter and a much deeper diver than the ohio? Also is the Borei magnetically detectable like the Ohio? Faster? Far better countermeasures? I really hope that the Borei A is completely superior to the Ohio in absolutely every technical category, including the SLBMs.


    Did they decide to not increase the number of bulavas on the borei-A because it would delay the building even more?

    I posted this in another thread, but it's relevant here too:
    New Skyph (Skif) sea bottom ICBM:
    http://svpressa.ru/war21/article/186921/?cba=1 skif
    They can put them in the Okhotsk Sea too. Cheaper than old Delta III/IVs & Borey SSBNs that also can safely deploy there & in the Arctic only. If these new ICBMs deployed in sufficient #s, at least some of the subs already built could be converted to SSGNs, perhaps eliminating the need for a few new Yasen SSGNs.
    The same goes for new Borey SSBNs which can dive deeper & whose BMs have longer range than the Ohio SSBNs:
