    Little late but…
    17 December is the birth date of the USSR/Russian Strategic Rocket Forces.For the passed 46 years approximately 10 milion people in several generations had been on duty.

    Neptune you didn’t tell me what is your opinion on this:
    “Information on the noise level of nuclear submarines is practically non-existent in the open literature. However, specialists have repeatedly said that the noise level of a nuclear submarine is higher than that of a diesel submarine running on batteries.This fact may be explained by several reasons. First, like a diesel submarine, a nuclear submarine may work at a minimal speed, running off the storage cells (batteries). However, the submarine’s nuclear reactor continues working and this is an additional source of noise. Second, the displacement for nuclear submarines usually exceeds, by several times, the displacement of diesel, and this requires a greater power to weight ratio. In our calculations we made the assumption that within a “quiet” mode the difference in noise level between strategic nuclear submarines and diesel submarines, which were developed at the same time, is 10 dB.”

    And for the noise generators i thought that you mean permament one,not decoy.And yes Korund is noise generator.

    “For propellor, US propellors are generally better made than any others, except for German ones and that really makes a difference for propellors.”
    And you are one of the mentioned specialists?Is that your statement as propellor designer?

    “As for the Inside, you think all that space is used for the reactor and the turbines”
    Yes i forget the evaporator and electricity generators,as well meny water pumps,batteries and so…..but no living compartments or stored weapons.

    “More space means more capabilities, if you have a 110m long hull, then you have a lot of length, surface and volume to put systems in”
    And you have nuclear reactor,turbines,all the complicated gear and 129 crew…

    “1. Engine Room. The engine room houses all the propulsion machinery, as well as the Ship’s Service Turbine Generators that supply the ship’s electricity”
    To me is more than the half of the sub.And if you make simple calculations
    as lenght/crew number you have 1.89 m/person pr.677/Lada and 0.85 m/person for LA class.

    “No foreign subs use noise generators”
    Well even the 671RTM had 2 MG-74 Korund noise simulation decoys (torpedo-sized)

    “Does Kilo have interior tiling? Does it have a propellor as advanced as a US sub?”
    The main engine is equipped with a shock-absorbing base and drives a large single-shaft, slanted seven-blade propeller (the 877- type has a six-blade propeller).So what is the advantage of the USA propellor?

    And what is your comment to this:
    “Information on the noise level of nuclear submarines is practically non-existent in the open literature.

    “It is also necessary to note that the noise level of a specific submarine doesn’t remain constant. During their service life, submarines wear out and their mechanisms become unbalanced. It is the opinion of specialists that during its operational life, the noise level of submarines grows on average by 5 dB.”
    Also in nuclear sub you have more “cuts” in the hull,thus increasing the water flow vortex and the hydrodynamic noise.

    in reply to: Cold Launch VS Hot Launch? #1823192

    Another disadvantage of the hot launch is that the missile MUST have booster.Modern missiles with complicated two mode motors,need just that to become even more complicated and heavy.As Garry pointed out:”Several cold launched weapons I have seen (including Klintok) have nose mounted vectoring rockets to point the nose of the missile in the direction of the target before the main engine fires.”
    Just like in this movie:http://tiberium.hit.bg/9K331_Tor-M1.wmv
    This is big advantage!You don’t need booster,don’t waste the energy of the main motor to make a turn towards the target.And another thing come to my mind…with cold launch you can preserve your launching platform.Just look at S-300V
    http://pvo.guns.ru/images/other/bel/tetr/s300v_4.jpg
    and see in this movie how the missile guidence system is safe from the motor blast.and just as in the Tor-1M movie the missile is already pointed against the target.Compare that to Patriot…

    This is how look the Ground Based Early Warning Radar systems in 2000: http://pvo.guns.ru/russia/index12.htm
    .Some of the systems now aren’t operational,but there is also some new.
    “…….The two facilities of the missile attack warning system (MAWS) that were put into operation in 2002 will contribute to that too. This is what Russian Space Troops Commander Anatoly Perminov said at a news conference.

    “The interceptors are getting old,” the Space Troops commander admitted. “However, they all undergo a technical inspection every month, and work is being done to prolong their service lifetimes. In 2002 a training launch of an interceptor was carried out at the Balkhash testing ground. The results showed the high potential of the Russian missile defense system and the opportunities to extend its lifespan. In the meantime, industries were assigned to update interceptors,” Perminov emphasized.

    Not only missiles will undergo the process of renovation, but also facilities that are part of the MAWS system. For example, after a fire at the Space Troops facility near the settlement of Kurilovo, Moscow region, it was decided not to restore the destroyed equipment, but to install new hardware instead.

    “We still have equipment which is almost 30 years old,” Perminov says. “However, this does not mean that it is useless. We recently conducted a joint experiment with the Americans. From their shuttle, we released spheres with a diameter of 5, 10, 15, and 20 centimeters. Unlike the American system, our MAWS system was able to detect a 5- centimeter sphere at a distance equivalent to that between Moscow and St. Petersburg. Even with their newer equipment, our American partners are unable to match that at present…”

    In 2002 the technical capacities of the Russian missile defense system actually expanded. It gained two facilities at once, unique in their capabilities: the Volga radar station at Baranovichi (Belarus) and the Okno (“Window”) optic-electronic complex in Nurek (Tajikistan). Volga can detect the launches of all types of strategic ballistic missiles within about 5,000 kilometers. Developed by the design bureau of the Krasnogorsk plant, the Okno optic-electronic complex is meant for automatic detection of high-orbit objects in space, at altitudes to 40,000 kilometers, tracking their orbits, and determination of their class, destination, state, and origin.

    Perminov noted that in 2003-05 the Space Troops would include 60- 65 military satellites and 15-16 dual-use satellites. As a result, “silent zones” will be completely eliminated from the Russian missile defense system.

    Hi again.This week i’m very busy with work but i’ll do my best to translate all i can.Pit i have some info for 671 in one book about russian submarines.
    http://tiberium.hit.bg/22.JPG
    The info about “pure” 671 is 14 pages.It will be easier to me to translate this,so tommorow i will post it.The book is quite good and cost only 9$!!And there is info about torpedo subs 627,627A,645,671,671RT,671RTM,685,705,705A,705D,945 and 971.And that is just for the torpedo subs.
    About the film.Some interesting part(from 31:36).The translation in not direct.
    “671RTM gain modernized power plant and that increased the lenght of the patrol to 3 months.Such long sail obliged the captain to search methods to keep the moral high(the captain explain-31:47)When we discover other(not soviet) submarine,we have a custom on the sub.The polit-commisar immediately go to the sub cooking room and the chef bring to all crew on shift to keep the strengh and the moral of the sailors a glass full of cream with a strawberry on the top(in this moment he smiles).After that they talk about the ration of the crew and the glass of wine that is compulsory.The doctors discover that is very healthy and was a reason for a good moral on the sub.
    Bye for now.

    Hi all.Few days ago i was surfing trought some russian military site’s and found this: http://www.army.lv/video/153.wmv
    It’ a nearly 40 minute movie about pr.671 submarine and it’s evolution.I know that few people on this forum know russian,but in the movie is a few things only seen in pictures.I’m on work right now so i don’t have much time to translate. They say that the reason of development of the first soviet torpedo reloader is because the torpedo room was too small,since the sonar was very large.They first think of redesing the sub,but that was time-costly(~12 minute of the film).The constructor of the sub explain how hard the work was,and he spend around 1000 days without his wife,and some marriages broked because of the intense work and presure.Around 22 minute of the film is said that in 1975 all the sub designer bureaus was summoned to a meeting with the presense of public prosecutor.The oversighting officer of Soviet naval forces complaint that the noise of the soviet subs was intentionally “put” in the design…..There is so much interesting in this movie,but i don’t have the time right now.Tomorrow….

    It’s exactly the same as the first picture.The dooooted path is “turning point of the flight path”,translated as “waypoint”.
