    Jane’s Fighting ships states that the max. speed of SSN-21,22 is 39 knots. SSN-23 is heavier and has the same reactor so it should be slower.
    There were rumors that the Seawolf had exceeded the highest speed ever by a manned submersible,44+knots by the Papa type SSGN

    In 1970 and 44.7kts was the official record. But I bet the modern day Sea Wolf class is a HELL of lot quiter at 40kts than the Papa class at the same speed!

    They have definitely lengthened it and increased the range. The original R-27 and R-27U have ranges of 2,400km and 3,000km respectively. I wonder about warhead accuracy though. Have they improved on the old guidance systems for the warhead(s)? The standard R-27/SS-N-6 has got a CEP of nearly 2km!

    Check your eyes/numbers again 🙂

    Right you are Victor, sorry. I was comparing the picture to a mental image of the LA class from memory and I got the impression it [SSN-774] was smaller. They are comparable in size, and I think the Virginia class is a few feet longer.

    And yes these Virginia class pics are GREAT!! 🙂

    Expensive? They have already been paid for… and can you think of a better way to use them? It is a very cheap way to dispose of older time expired missiles or missiles that must be destroyed… that have very good accuracy BTW.

    If you are using old stock then fine. But built for the purpose? Costly. And accurate I know, but maybe not enough for a conventional kill. I think you will need a CEP of better than 50m, more like that of a JDAM, or around 10m. Unless of course you up the warhead charge…

    They were gotten rid of for a reason… the very short flight times give very little warning. Plus proliferation problems now suggest that legal IRBMs would probably sell like hotcakes for Russia, but I don’t think the US would have that many customers so it probably isn’t in the US’s interest to revive that weapon system type.

    Short range missiles then. 600-1000km class. Even less if you control ground near the intended target. The Russians used the very short ranged SS-21s in Chechnya did they not?

    Good points, but as long as the missile is heading in the right direction the ship has to use it’s self defence systems against it.

    The more missiles launched against a target, the bigger the problem for it’s defences, the lower the chances for survival.

    True, a saturation attack even by several lighter but very fast missiles would warrant alarm and problems. You might even be lucky and get an Arizona style magazine strike. 😉

    Looks a LOT smaller than I expected. Compared to the LA class the Virginia is the much smaller cousin.

    The ABM system around Moscow has been tested and upgraded every year it has been operational… tested against ICBMs that is.

    Yeah but Garry those ABMs that ring Moscow use nuclear warheads to shatter inbound ICBMs if I am not mistaken. The ARROW, PAC-3, etc., use a bullet-on-bullet hit-to-kill, or conventional close proximity warhead kill method. That kind of technology is still in it’s infancy.

    See it before. But the under carriage looks real enough. Wonder what it was borrowed from?

    Well according to Norman Polmar and K.J.Moore, the authors of COLD WAR SUBMARINES: The Design & Construction of US and Soviet Submarines 1945-2001, the non-acoustic sensors forward of the sail on the AKULA class may not be directly related to the detection of other submarines as far as I can tell. They are used for temperature, turbulence, and radiation readings. I am quoting from the book.

    The photo was taken in the UK, so could they be aerial display smoke trail canisters that have been added to the rear?

    Yet another Su-35 incarnation? Is this Su-35BM going to be a tech demo platform, or are they still hoping to sell the Su-35 as opposed to the Su-30?

    Nah, couldn’t help ya there mate.

    Plenty of alternatives though – I use 9 forums regularly with another three that I sometimes visit.

    NINE! Crickey, how do you find time to do anything else? I post at 3 or 4 almost everyday, and drop into another 1 or 2 now and then, and that keeps me busy for ages! Must admit though a good proportion of my net time is spent on theses forums. 🙂
