    Austin,

    I am speaking about AMPULATED liquid fuel missiles – R-29, R-29R, R-29RM and RMU. They are fueled at the factory and then fuel valve is sealed by welding for entire service life and no refuelings are carried out. At least, that’s how it’s explained by Makejev design bureau.

    But the Bulava has other very important advantages (e.g. speedy boost phase), along with maintenance issues (much less demanding).

    Could you elaborate, please, on maintenance issues of ampulated liquid fuel missile compared to solid fuel? What exactly is much less demanding?

    Actually, it was possible to see on Google Earth both Oscar-I being dismantled in Severodvinsk. The list of boat types is a bit strange. Both Kondors (Sierra-II) should be ok for upgrade. I’m bit surprised about type called Bars, it should be Schuka-B, if they refer to 971. Bars was the lead boat of the type.

    Is any Oscar 2 under refit currently and are being upgraded ?

    Voronezh has just been re-launched at Zvezdochka repair facility after medium refit. Upgrades are expected to start in 2010.

    Thanks , some how google does not fully translate the link.

    Any idea on the weapons and sonar suite of Yasen ,have they mentioned or hinted in those journals ?

    I am more keen on the supersonic missile that Yasen will have in those VLS tube ? may be they might retrofit it on Oscar 2 during its upgrade.

    Sonar suite Irtish with spherical bow antena Amfora, automated signal analyzer and target identification system Ayaks-M.

    I’d be happy to know what are the “enhanced range cruise missiles” announced for Yasen. May be Granat with supersonic stage from Biryuza (Club).

    snake65 , from what I have read about Bark its USP was suppose to be the weight reduction of 50 % compared to SS-N-20 , and the figure i read was ~ 45 T , any source for that 80 T figure ?

    The precise weight of Bulava is 36.8 T per START exchange information link

    Well, the figure has been widely used on Russian forums and in a couple of Russian reference books on missiles. I pay respect to an article in Russian newspsper NVO in 2007, because it was written by two people from Makejev design Bureau where Bark (R-39UTTH) was designed. The table is at the end of article.

    Thanks for the clarification , but have few questions

    The picture from the short movie does not actually represents the real Borei though , case to point is the position of the sail much closer to the bow , and the shape of the sail is different from real borei.

    If Pics 3 and 5 are the real images which are described as CGI images of Severodvinisk then it represents the image of the short movie.

    BTW if the CGI is the real image of the Yasen the top view of the CGI shows Sonar/Sensor Patch all over her hull and sail which is damn impressive

    BTW Boris Spassky presence should not come as a surprise , though Malachite and Rubin have their respective skill and domain of expertise , I am quite sure these organisation might be doing a peer review work of each others project , quite a normal thing to do in scientific work , I am quite sure these two design bureau might not like to duplicate their work and learn from each other but retaining their core expertise area and design approach and solution to solve their respective problem

    No, no, I didn’t mean that. The drawing shows Yasen, not Borei. The movie itself is mostly on Borei and the epziode with the drawing comes in kind of accidentaly and narrator doesn’t explain that the drawing is of Yasen.
    Spassky should reserve his comments to designs of his Bureau and let the Chief of Malakhit introduce his boat, that’s common practice. It doesn’t mean that Spassky is ignorant of designs of other Bureaus, but it is appropriate that the author of the design presents it to top brass.

    Bark – 80 tons, Bulava – 36. 12 Barks – 960 tons, 16 Bulavas – 576 tons.

    I see that secretprojects have finally gathered most of the Severodvinsk pics which are available on the net.
    First post: Pics 1 and 2 are from short movie on subs built in Severodvinsk, it’s more about Borei actually. The interesting move there is the fact that person who is explaining the diagram is Boris Spassky, Cief designer of Rubin (designer of Borei), and has nothing to do with Malakhit designed Severodvinsk. The listening man is Mikhail Kasjanov, PM of Russia at that time, which allows to set year when this happens. Pics 3 to 5 are CG images which first appeared in article by Deputy Chief designer of Malakhit in Gangut #14 (issued in 1998), they were described as CG images of Severodvinsk.
    Second post: first pic is a find by a professional shipmodeler from Severodvinsk, he has a nice model made fom that drawing, second is either from Krylov institute annual report or from a book on Rubin SPKB (frankly, I don’t remember which), the other pics are from Krylov institute annual report of 2007, 2008.
    Hope that we don’t have to wait much longer to see the real thing 😎

    Let the Russians have that and return the money we paid. We are not responsible for them underestimating the cost, nor are we responsible for them employing unskilled welders. The Maximum we should agree is calculate the price difference because of dollar value changes and pay them that. Or esle they can have it for themselves.

    Full Speed IAC 1 & 2 😉

    No sweat. Sue them in Stockholm. And then wait 8 years for IAC.

    pics from last april

    Of course, the contract has become unprofitable for Russia. They severely underestimated the amount of repair and rebuild and severely underestimated competency and level of workmanship (high wages-mediocre quality) at Sevmash. The amount of welding, for instance, has trippled compared to the initially estimated, mainly because of low skills of welders.

    This effectively means more delay to second and third Lada and a farewell to RuNavy plans for 8 Ladas till 2015.

    This seems to be the source for line drawing. I’m not sure about the absence of pumpjet and the sonar arrangement looks wrong, YD and Severodvinsk have the same sonar suite and this one certainly looks more like modified Skat (possibly the all-digital Skat-3) and not Irtish/Amfora.
