    Project 877/636: Kilo class SSK

    Post  Vladimir79 on Tue Oct 13, 2009 10:57 pm

    Admiralty Shipyards have begun to modernize diesel-electric submarine Kilo class

    PETERSBURG, October 9. (Itar-Tass). Modernization of diesel-electric submarine Kilo class started in the company "Admiralty Shipyards".

    According to ITAR-Tass director general of JSC Vladimir Alexandrov, the submarine of Project 636 will be replaced and prevention systems, mechanisms, establish new types of weapons.

    Submarine Kilo "Project 636, designed in the CDB for Marine Engineering" Rubin "is considered one of the most low-noise in the world. It is equipped with four missiles, 18 torpedoes and 24 mines. The crew of the ship - 52 people. The submarine can dive to a depth of 300 m and move in a submerged position with a speed of 37 km / h. "Kilo" is designed to destroy submarines and surface ships, protect naval bases and communications, reconnaissance.

    Currently, the company completed the construction of two submarine export Kilo class. Under the contract signed by Rosoboronexport, one of them will be transferred to customers in 2009, another - in 2010

    Russian submarine towed to port after engine malfunction

    RIA Novosti

    23/11/200901:42

    MOSCOW, November 23 (RIA Novosti) - A Russian diesel-electric submarine from the Black Sea Fleet is being towed to the port of Novorossiisk after suffering an engine malfunction during sea drills, a Black Sea Fleet official said.

    The Alrosa, a Kilo class diesel submarine, was on a training exercise in the Black Sea on Saturday when it reportedly experienced some problems with its jet propulsion system.

    "The submarine is being towed in a surfaced position to the port of Novorossiisk. Its arrival is expected on Monday. Experts will establish the cause of the malfunction there," the source said.

    A Russian Navy spokesman earlier said the situation on the submarine was under control and there was no danger to the crew.

    He also said the submarine would continue the drills after the problem is fixed.

    Alrosa, commissioned in 1990, is the only submarine in active service with the Black Sea Fleet. It is based at a Russian naval base in Sevastopol on Ukraine's Crimean Peninsula.

    Actually I have a bit of trouble believing that chart Austin, first of all those American stars are nukes and not diesel electrics.

    Second is it showing diesels operating with diesel engines running or on electric drive... quite different things BTW.

    When running off batteries most diesel electrics would compare quite favourably to most nukes as there are no noisy gears or reactor cooling pumps operating.

    Equally even a noisy sub can be operated near a choke point in a lie and wait tactic where it can remain noiseless and motionless waiting and listening for targets to come past it.

    ^^ Garry , Dont take that chart as a gospel truth but a trend in conventional submarine.

    Its true that Nuclear Submarine have lot of pumps ,reactor running which would make them noisy , compared to conventional subs running on battery.

    But Nuclear submarine have far more comprehensive silencing measures implemented in them , the much bigger size and unlimited power allows them to do so . While Diesel Electric Submarine have their limitation on size and power hence they are limited to what can be implemented to reduce acoustic field.

    There is some thing called Full Silence regime on Nuclear Submarine where it moves at slow speed ,all non essential stuff including pumps are shutoff , moments are restricted ( even no toilets ) , so Nuclear sub can remain and be more silent then diesel subs.

    Choke point business are best done by Conventional Subs , they are small in size ,choke point depth ( generally not greater then 200 m ) allows them to lie low and run on battery for long without the need to recharge for long time and AIP makes it much longer.

    Its always good to have a mix of Nuclear and Conventional subs as they have their own task cut out and are good at specific task , In US there are lobbies that think opting for Conventional Subs will eventually kill Nuclear submarine and their associated industry

    Thankfully Russia did a right thing of having mix of both , its a cost effective option as well.

    My main problem with the chart is that it doesn't actually list the scale of noise, it just says it is in decibels.
    As such the scattering of subs on the chart mean little except the downward slope suggests they are all getting quieter... which is a given anyway.

    Its true that Nuclear Submarine have lot of pumps ,reactor running which would make them noisy , compared to conventional subs running on battery.

    There are reactors that use natural circulation for cooling, but at the end of the day lots of noises on subs like opening torpedo doors, pumping water into and out of ballast tanks for trim, propeller noise, mechanical noise is going to be less on an electric than on any other type. Non nukes have their advantages especially in shallow waters because of their smaller size and manoeuvre capability and of course cost, but their fundamental advantage is in their reduced noise signature because electric motors make very little noise even at full power.


    But Nuclear submarine have far more comprehensive silencing measures implemented in them , the much bigger size and unlimited power allows them to do so .

    If that were true then the US could simply test its anti sub capability against its own nuclear power subs instead of inviting European and Australian conventional subs to exercise with them so they can practise operating against conventional subs.
    It seems these tests were useful and the USN has invited a European country to keep sending its subs for exercises.
    What would be the point if diesel electrics were noisier than nukes?

    There is some thing called Full Silence regime on Nuclear Submarine where it moves at slow speed ,all non essential stuff including pumps are shutoff , moments are restricted ( even no toilets ) , so Nuclear sub can remain and be more silent then diesel subs.

    Yes, I know about running silent on a sub, but even running on silent in a nuke and a diesel electric are not the same thing... in a nuke you keep the reactor running which means noise. In a diesel electric that means running on electric which is much quieter clearly... even in a natural circulation reactor there is the noise of fluids moving that doesn't sound like other things in the ocean.

    In US there are lobbies that think opting for Conventional Subs will eventually kill Nuclear submarine and their associated industry

    There are lobbies in the US that think universal healthcare is communism too. Smile

    A kilo could probably operate for 4-5 days on batteries before having to recharge... that is plenty of time to sit and wait for the right target or lay mines and sneak away to recharge.

    These are just trends and not a ballpark figure ,even if scale were to be provided it would be little value.

    I find it hard to believe to believe that Australian Collins are being rated in noise equal to advanced Kilo when they were mentioned as Rock Band under water by Western media and German U-212 being rated lower then adv Kilo when it should be on par or better.

    There are reactors that use natural circulation for cooling, but at the end of the day lots of noises on subs like opening torpedo doors, pumping water into and out of ballast tanks for trim, propeller noise, mechanical noise is going to be less on an electric than on any other type. Non nukes have their advantages especially in shallow waters because of their smaller size and manoeuvre capability and of course cost, but their fundamental advantage is in their reduced noise signature because electric motors make very little noise even at full power.

    Yes I am aware of the use of natural circulation at slow speed but those noises from ballast , motors , trip etc affect conventional and nuclear subs and a nuclear subs have much bigger sonars and other sensors to catch up such noises compared to conventional subs.

    Conventional subs are good for choke and intelligence gathering operations.

    If that were true then the US could simply test its anti sub capability against its own nuclear power subs instead of inviting European and Australian conventional subs to exercise with them so they can practise operating against conventional subs.
    It seems these tests were useful and the USN has invited a European country to keep sending its subs for exercises.

    They do lot of test viz a viz conventional subs against Australian or European countries , these are tactics , weapons ,how to play ball in shallow waters and even open seas , lot of stuff besides noise , A sub is more then just noise.

    What would be the point if diesel electrics were noisier than nukes?

    because its cheaper to build and operate ,very few countries can build and operate quality nuke subs and with AIP the conventional subs are getting better and as I said submarine is more then noise , Tactics , Weapons ,Training and Doctrine play an equal role.

    Yes, I know about running silent on a sub, but even running on silent in a nuke and a diesel electric are not the same thing... in a nuke you keep the reactor running which means noise. In a diesel electric that means running on electric which is much quieter clearly... even in a natural circulation reactor there is the noise of fluids moving that doesn't sound like other things in the ocean.

    Nuke Subs do have battery on them to provide powers and they have small creeper propellers one can see in Akula that gives them slow speed.

    All things being equal which I have mentioned above a 4th gen Conventional Sub like Lada will have its own advantage over 4th gen Yasen in shallow water operation.

    So conventional subs do have an edge in specific roles.

    There are lobbies in the US that think universal healthcare is communism too. Smile

    I think that was also a reason Democrat got defeated in recent Senate elections , health care is good as long as it can profit the big companies out there.

    A kilo could probably operate for 4-5 days on batteries before having to recharge... that is plenty of time to sit and wait for the right target or lay mines and sneak away to recharge.

    The Kilos are quite potent subs and can do many different task and these days they even come with Klub.

    SSK Kaluga Leaving Covered Slipway

    Post  George1 on Thu May 03, 2012 11:06 pm

    JSC Zvezdochka Ship Repair Center will withdraw diesel electric submarine (SSK) Kaluga on May 26, reports Central Navy Portal.

    SSK Kaluga is the first Project 877 Varshavyanka Russian conventional submarine passed modernization and interim overhaul over the last twenty years.

    The sub arrived at Zvezdochka in 2000 and had been staying at the yard's quay and on slipways for almost 10 years pending repairs. Due to lack of financing, works on Kaluga were postponed for ten years. Full-scale repair started only in 2010.

    After launching, the sub will be outfitted afloat. Mooring trials will start in June; in the fall of 2012, SSK Kaluga will take the sea to pass shipyard's trials.

    Late in 2012 the submarine will be handed over to the Navy and be in service for 10 years.

    Third Varshavyanka class submarine for Russia’s Black Sea Fleet to be launched soon

    ST. PETERSBURG, August 28./ITAR-TASS/. The third Varshavyanka class submarine - Stary Oskol of Project 636.3, built for Russia’s Black Sea Fleet, will be launched at the Admiralty Wharves Shipyard in St. Petersburg on Thursday.

    Commander-in-Chief of the Russian Navy, Admiral Viktor Chirkov is expected to attend the ceremony.

    A total of six Varshavyanka class submarines will be built for the Black Sea Fleet. According to the Navy commander, the submarines “will fulfil jointly with the naval surface forces and antisubmarine aircraft complex tasks in their responsibility zone.” They will also strengthen the combat capability of Russia’s naval task force in the Mediterranean.

    The head submarine of the series - Novorossiysk, was laid down in August 2010 and delivered to the fleet in the presence of Russian Defense Minister Sergei Shoigu on August 22, 2014. After a voyage to the North it will pass two-week deepwater sea trials at the Northern Fleet ranges. Rostov-on-Don - the second submarine of the project and simultaneously the first series Varshavyanka for the Black Sea Fleet, was laid down in November 2011 and launched on June 26, 2014.

    The Stary Oskol submarine was laid down in August 2012, and the fourth submarine of the project - Krasnodar - in February 2014.

    The laying down of the fifth and sixth submarines of the class is planned in late October this year, for the 310th anniversary of Admiralty Wharves. The submarines will be named Veliky Novgorod and Kolpino.

    The Varshavyanka-class third-generation diesel-electric subs were designed by the Rubin Central Design Bureau for Marine Engineering (St. Petersburg). Dubbed by the US Navy as “black holes in the ocean,” they are almost undetectable when submerged, designed for anti-shipping and anti-submarine missions in relatively shallow waters.

    The submarines, armed with torpedoes, mines and cruise missiles, displace 3,100 tonnes, reach speeds of 20 knots, can dive to 300 metres and carry crews of 52 people.

    Russia's first Varshavyanka-class submarine, the Novorossiisk, has entered service with the Black Sea fleet

    Russia's first Varshavyanka-class submarine, the Novorossiisk, has entered service with the Black Sea fleet

    MOSCOW, September 17 (RIA Novosti) – Russia's first Varshavyanka-class submarine, the Novorossiisk, has entered service with the Black Sea fleet, the Southern Military District's press service said Wednesday.

    The submarine currently remains at the Admiralty shipyard in St. Petersburg and will head to the Black Sea port of Novorossiisk after completing final trials with the Northern Fleet.

    The Defense Ministry has ordered a total of six Varshavyanka-class subs, dubbed "black holes in the ocean" by the US Navy because they are nearly undetectable when submerged.

    The Novorossiisk was laid down in August 2010. Back in August 2014, Russian Navy Commander Admiral Viktor Chirkov confirmed that two Project 636.3 diesel-electric submarines, the Novorossiysk and the Rostov-on-Don, would join the Black Sea Fleet by the end of the year. The construction of all six subs is to be completed by 2016.

    The submarines are primarily intended for anti-ship and anti-submarine missions in relatively shallow waters. They will be crewed by 52 submariners, have an underwater speed of 20 knots and a cruising range of 400 miles with the ability to patrol for 45 days.

    Guess it's pretty long way to get to the BSF base.


    Other than that, would love to see better 636 with AIP in the future.

    According to the U.S. Navy the Improved Kilo's are considered "black holes" of the oceans, and like blackholes their both invisible and very dangerous.

    and why the F every diesel-electric sub out there still use conventional propeller ?

    Being silent is sure nice BUT don't you ever think of clogging whenever the sub operate in coastal area ? Where the sea bed might be shallow.

    Or perhaps loss of propulsive efficiency ?

    Yeah, pump jets aren't without problems.... They are less efficient at lower speeds, which is a problem as diesels aren't known to be very fast... As Stealth said, they can be clogged with just about anything, and that problem gets much worse at the shallow depths the Kilos will operate... - Aka, they aren't any good for diesel powered subs! Most importantly, and this make you a hypocrite Navy, is that pump jets are much more complex and expensive. Which just happens to be your main argument *against AIP*!

    That being said, pump jets can be worth while on larger subs and ships.
