    disappointed to see that Russia did not put its best efforts due to economic probs to have a version with 8-cell VLS and an AIP section when the 636 was revived.
    Well that was basically going to be the Lada class...

    Makes little sense to make such big changes this late in the production cycle.

    But the AIP followup to Kilo class could be lengthened to accommodate VLS. And it would also provide some space for extra batteries.

    Russia launches sixth and final improved Kilo-class submarine
    Nicholas de Larrinaga, London - IHS Jane's Defence Weekly | 01 June 2016

    Here: http://www.janes.com/article/60884/russia-launches-sixth-and-final-improved-kilo-class-submarine

    Russia launched its sixth and final Project 636.3 (Improved Kilo-class) diesel-electric submarine on order for the Black Sea Fleet on 31 June, the Russian Ministry of Defence (MoD) announced.

    Kolpino was launched at the Admiralty Shipyard in St Petersburg in a ceremony attended by Vice Admiral Alexander Fedotenkov, deputy chief of the Russian Navy.

    At the ceremony, Vice Adm Fedotenkov revealed that Russia is now planning to order Project 636.3 submarines for the Pacific Fleet, and will later build more Improved Kilo-class boats for Russia's Northern and Baltic Fleets.

    Russia currently has four Project 636.3 vessels commissioned into service with the Black Sea Fleet ( Novorossiysk , Rostov-Na-Donu , Stary Oskol , and Krasnodar ) and launched a fifth ( Veliky Novgorod ) in March that is due to soon begin sea trials.

    Russia Surprised UK Needs Help to Track Submarines Near Surface



    The Royal Navy frigate HMS Kent has been shadowing a Russian Kilo-class diesel-electric submarine from the North Sea through the Channel.

    Russia has poked fun at the UK’s intercept of one of its submarines, saying it was surprised that the Royal Navy needed NATO’s help in tracking a submarine travelling at slow speeds “in surfaced position.”

    Russia’s Stary Oskol submarine was first detected in the North Sea by NATO ships on Tuesday, and was then escorted by Britain’s frigate HMS Kent past the Strait of Dover on Wednesday morning.

    Daniel Thomas, the commander of HMS Kent, said that detecting the Russian submarine “was a combined effort with NATO allies and shadowing such units is routine activity for the Royal Navy.”

    Following the incident, Russia’s Ministry of Defense issued a statement on Wednesday, mockingly saying “an up-top sub can’t be missed.”

    “The Russian Defense Ministry is surprised that joint UK-NATO efforts were required to discover a submarine traveling in a surfaced position at slow speed, accompanied by a tugboat,” the statement read.

    “It would have been strange if the Royal Navy together with its NATO allies failed to notice the submarine, particularly considering the fact that our sailors have been greeted — according to an old tradition — by passing merchant vessels from different countries in the Barents, Norwegian and Northern seas over the past days," it continued.

    Meanwhile, British media hailed the move by the Royal Navy, claiming that that the sub was there on Russian President Vladimir Putin’s personal orders prior to a Euro 2016 football match between the two nations on Saturday. Laughing

    “Vladimir Putin has sent an attack submarine into the English Channel – just days before England battle Russia in the Euros,” the Sun wrote.

    The Daily Mail and Metro echoed the same notion, with the latter writing “Putin sends submarine into English Channel days before England vs Russia at Euro 2016.”

    UK Defense Secretary Michael Fallon also praised the Royal Navy in a press release, saying “This shows that the Navy is maintaining a vigilant watch in international and territorial waters to keep Britain safe and protect us from potential threats.”

    According to Moscow, the Stary Oskol was on a journey from the Northern Fleet in the Arctic to the Black Sea in order to enter its new home base in Sevastopol, located on the Crimean peninsula.

    lol!
    The Russians have a tendency to use such magnificent language on this sort of thing: managing to be formal & nominally polite while simultaneously boldly scathing by pointing out obvious important facts that get (conveniently) left out by Western MSM/Politician propaganda.

    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

    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
