    What's the status of the pump jet-featuring Alrosa?

    Built ages ago & all the Kilos they built since use the normal props -> I'd say status = fail or at least not enough benefit to make up for the downsides.

    Edit: guess I misunderstood the question below answer is probably more legit pale

    Beint on long term overhaul since 2014. Overhaul is supposed to be made of 3 phases, 2 phases are done and last phase is being performed atm. Its currently in the workshop hangars after on 18th April 2016. it was pulled from the dry dock.

    To provide a point of reference, the following acoustic signatures are from "Chinese Evaluations of the U.S. Navy Submarine Force" and "CHINA’S FUTURE NUCLEAR SUBMARINE FORCE"

    Ocean background noise - 90 decibels
    Seawolf-class - 95 decibels
    Virginia-class - 95 decibels
    636 Kilo class - 105 decibels
    Akula-class - 110 decibels
    Type 093 - 110 decibels
    Type 094 - 120 decibels

    Could be interesting to know the speed/deep and propulsion mode (diesel or electrics) for these numbers.

    interesting how Chinese measured Seawolf/Virginia noise? no source provided or I am missing omething? all other sources are either US intel or authors nothing from China or Russia. Funny is that 677 is noisier than 636.6 built for China accorduing tho those sources Very Happy

    Which Akula they're talking about ? Because Los Angeles class SSN faces difficulties in finding 971-Akula SSN ( 90 db )

    I think thats the only time I've seen actual numbers instead of scale-free graphs Suspect

    I wonder which 636 they are supposed to be & how much difference there is between the versions?

    Nicely rounded numbers.
    Submarine noise levels are closely guarded secrets by the military.
    These figures have zero credibility. At least they should have not rounded numbers. Hey, if they had put decimals, it would have looked more credible.


    Fools.

    It is more than that.

    An electric submarine must generate less noise than a nuclear in electric mode.
    It hasn't got cooling pumps, boiling water in the reactor and control roads in it.

    Additionaly the cruisinf speed of the nuclear submarine higher than for the diesel/electric, means more noise at the same speed.


    If the diesel works in diesel mode then OK, it is noisy ,but not in electric mode.

    Ocean background sound is in the 55 to 85 dB range.   The rest of these number are similar trash.  The noise level is not
    a constant but a function of submarine speed, local currents and turbulence if in the mixed layer, screw speed and power
    plant operation regime.   A submarine that is "off" will not make any noise relative to the background.    Then we have
    the peculiar properties of the thermocline at the base of the mixed layer where acoustic modes are refracted and ducted
    horizontally.   It is layer where the background noise maximizes so a submarine sitting in this layer will be very hard to detect.
    The 636 is specifically designed to cruise in this layer and when it operates in electric mode it really is a "black hole".   The
    "105 dB" figure is retarded fantasy masturbation.

    To be fair the 110 is for the old Akula's.

    The modernized ones are supposed to be quieter by how much well remains to be seen

    Another picture of the Stary Oskol escorted by Turkish Coast Guard vessel TCSG-88 and trailed by Turkish ASW boat P-1207 TCG Tekirdağ during the submarines passage through Istanbul on 29th June. Frigate TCG Yıldırım was waiting for the submarine at the northern entrance of the Strait. Everyone recording as much as possible of her sounds no doubt.

    Last overall or last for Black Sea Fleet?

    There should be 6 more for Pacific Fleet right? And Lord knows Baltic Fleet could use some of them.

    Russian Defense ministry sign contract for 6 Project 636 submarines

    Post  Ned86 on Wed Sep 07, 2016 2:00 pm

    Russian Defense ministry sign contract for 6 Project 636 submarines for pacific fleet.
    Submarines will be built between 2018-2021.

    Finally pacific fleet will get real boost with these new 6 submarines. I hope they will modernize some older Kilo's already in service, so total number of Diesel submarines in pacific fleet would be increased.
