== Role ==
The Project 877 attack submarines were mainly intended for [[Anti-surface warfare|anti-shipping]] and [[anti-submarine warfare|anti-submarine]] operations in relatively shallow waters. Original Project 877 boats are equipped with Rubikon MGK-400 sonar system (with [[NATO reporting name]] Shark Gill), which includes a mine detection and avoidance sonar MG-519 Arfa (with NATO reporting name Mouse Roar).

Newer Project 636 boats are equipped with improved MGK-400EM, with MG-519 Arfa also upgraded to MG-519EM. MGK 400E can detect submarines with 0.05 Pa/Hz noisiness in {{cvt|16|km}} and surface vessels with 10 Pa/Hz noisiness in {{cvt|100|km}}.<ref>{{cite web |url=http://roe.ru/eng/catalog/naval-systems/shipborne-electronic-systems/mgk-400/ |title=MGK-400EM Sonar |website=[[Rosoboronexport]] |access-date=18 July 2020}}</ref> The improved sonar systems have reduced the number of operators needed by sharing the same console via automation.

[[Anechoic tile]]s are fitted on casings and fins to absorb the sound waves of active sonar, which results in a reduction and distortion of the return signal.<ref>Anechoic tiles are fitted on casings and fins to absorb the sonar sound waves of active sonar, which results in a reduction and distortion of the return signal.</ref> These tiles also help attenuate sounds that are emitted from the submarine, thus reducing the range at which the submarine may be detected by [[passive sonar]].<ref>{{cite web |url=http://www.russiafile.com/kilo.htm |title=Kilo-class Submarines |website=Russiafile.com |access-date=29 October 2008 |archive-url=https://web.archive.org/web/20150924092844/http://www.russiafile.com/kilo.htm |archive-date=24 September 2015 |url-status=dead}}</ref>

Project 636 and 636.3 submarines can launch [[Kalibr]] (and their Club export version) cruise missiles. It was reported in September 2022 that they can carry four Kalibr missiles, and can launch them through two of their six torpedo tubes.<ref name=sutton/>

==History==
A single Project 877 submarine, {{ship|Russian submarine|B-871||2}} ''Alrosa'', is equipped with [[pump-jet]] propulsion, instead of a [[propeller]].<ref>{{cite web |url=http://www.alrosa.net/eng/ |title=Kilo Class Submarine "Alrosa": Black Sea Fleet, Russian Federation |website=Alrosa.net |access-date=8 March 2014 |url-status=usurped |archive-url= https://web.archive.org/web/20080603220020/http://www.alrosa.net/eng/ |archive-date=3 June 2008}}</ref> It has been retrofitted for the Kalibr missile.<ref name="newdick">{{cite news |last1=Newdick |first1=Thomas |title=Russia's Only Pump-Jet Kilo Class Submarine Is Back To Attack Ukraine |url=https://www.thedrive.com/the-war-zone/russias-only-pump-jet-kilo-class-submarine-is-back-to-attack-ukraine |agency=The Drive |publisher=Recurrent Ventures |date=28 June 2022}}</ref>

It was planned for Project 636 (Improved Kilo) to be succeeded by the {{sclass2|Lada|submarine|4}} in [[Russian Navy]] service. However, by November 2011 it was apparent that the Lada class would be delayed because ''Sankt Peterburg'' (B-585), the lead boat of the class, had shown major deficiencies. On 27 July 2012, the Russian Navy commander-in-chief announced that construction of the Lada-class submarines would resume, having undergone design changes.{{cn|date=February 2023}} Series production was reported to be underway in the latter 2010s.<ref>{{cite news |url=https://www.naval-technology.com/projects/project-677-lada-class-project-1650-amur-class-submarines/ |title=Project 677 Lada Class / Project 1650 Amur Class Submarines |newspaper=Naval Technology}}</ref>{{update after|2014}}<!-- so what happened after 2014?  is this even still real?  any sources in, say, 2016 or later that show the Russian Navy is still actively fielding the Lada class? -->

The Russian Navy also moved forward in the late 2010s, with the construction of Project 636.3, also known as Improved Kilo II. The first-in-class was named ''Petropavlovsk-Kamchatsky'' (PPK) and was launched by the head of [[Admiralty Shipyard]] Alexander Buzakov on 28 March 2019, or some thirty months after commission.<ref name=fsgtd/> By November 2019, six units had been built for the [[Black Sea Fleet]] and further boats were proposed, but not funded, for the Pacific and Baltic Fleets.<ref name=diplomat20191122>{{cite web |url=https://thediplomat.com/2019/11/first-project-636-3-kilo-class-attack-sub-to-enter-service-with-russias-pacific-fleet-this-month/ |title=First Project 636.3 Kilo-Class Attack Sub to Enter Service With Russia's Pacific Fleet This Month |date=22 November 2019 |first=Franz-Stefan|last=Gady |website=The Diplomat}}</ref>

In June 2022, an unconfirmed report from within Russia's defense industry suggested that a further tranche of six additional Project 636.3 vessels might be ordered to start construction in around 2024.<ref>{{cite web | url=https://tass.com/defense/1465805 | title=Shipbuilders to build a series of Project 636.3 submarines for Russia's Northern Fleet }}</ref> The class "is slightly longer in length — the sub's submerged displacement is around 4,000 tons — and features improved engines, an improved combat system, as well as new noise reduction technology; it can fire both torpedoes and [[cruise missiles]], launched from one of six 533-millimeter torpedo tubes."<ref name=fsgtd/> The class has a seven-bladed propeller, instead of the six-bladed propeller of the Project 877 class.<ref name=newdick/>

Kilo-class attack submarines originally began entering service with the [[Soviet Navy]] from 1980.{{Citation needed|date=November 2024}}

At the beginning of 2014, the Chinese PLA Navy held an emergency combat readiness test.<ref>{{cite web |title = Courage and bloodiness have always been the backbone of soldiers and the edge of victory. |url = http://news.mod.gov.cn/pla/2014-10/22/content_4545847.htm |author=Wang Tao |date=2014-10-22 |website=PRC Ministry of National Defense |access-date=2018-07-13 |archive-date=2018-07-13 |archive-url = https://web.archive.org/web/20180713143304/http://news.mod.gov.cn/pla/2014-10/22/content_4545847.htm |url-status=live }}</ref> The Kilo-class submarine ''Yuanzheng 72'', deployed on a combat readiness voyage encountered a "cliff" caused by a sudden change in seawater density. Because the seawater density suddenly decreased, the submarine lost its buoyancy and rapidly fell to the [[seabed]] more than {{convert|3000|m}} deep. The pressure on the submarine increased sharply, and the main engine room pipeline was damaged and water entered.  The vessel lost power due to a large amount of water entering the main engine room. The crew reacted quickly, the submarine resurfaced in three minutes, avoiding disaster. The voyage was notable for creating many firsts for PLAN's submarine service.<ref>{{cite web |title = South China Sea Fleet submarine suddenly lost buoyancy during a voyage and encountered the most dangerous 3 minutes |url = http://news.ifeng.com/a/20140409/35582388_0.shtml |date=2014-04-09 |website=凤凰网 |access-date=2018-07-13 |archive-date=2018-07-13 |archive-url = https://web.archive.org/web/20180713143237/http://news.ifeng.com/a/20140409/35582388_0.shtml |url-status=live}}</ref><ref>{{cite web |title = Media reveals military awards: Most awards are related to "aircraft carriers" |url = http://sc.people.com.cn/n/2014/0901/c345460-22169825-3.html |date=2014-09-01 |website=人民网 |access-date=2018-07-13 |archive-date=2018-07-13 |archive-url= https://web.archive.org/web/20180713142540/http://sc.people.com.cn/n/2014/0901/c345460-22169825-3.html |url-status=live }}</ref>

In 2015, five Kilo-class submarines were deployed to the [[Russian naval facility in Tartus]], Syria. At least two of the units reportedly attacked land targets inside Syria with 3M54 Kalibr cruise missiles (NATO designation: SS-N-27A "Sizzler").<ref name=diplomat20191122/> 8 December 2015 marked the first time a Kilo-class submarine fired cruise missiles against an enemy.

The first submarine entered service in the [[Soviet Navy]] in 1980, and the class remains in use with the Russian Navy today; around 11 original Kilo-class vessels believed to still be in active service with the Russian Navy (as of 2023), while new Improved Kilo–class subs are being delivered through the 2020s to replace them. About forty vessels have been exported to several countries:

=== Possible purchasers ===
The government of Venezuela expressed interest since 2005 in acquiring nine AIP-powered conventional submarines, either the German U214 or later the Amur 1650. There was a Russian counteroffer due to technical issues at the shipyards back then, for five Project 636 Kilo-class and four Amur 1650, but it hasn't gone through yet.<ref>{{Cite web |last=InfoDefensa |first=Revista Defensa |title=Venezuela y la renovación de su fuerza submarina.

In 2017, the [[Philippine Navy]] showed interest in the Kilo-class submarine as part of its modernization program. Defense Secretary [[Delfin Lorenzana]] said the country was evaluating a Russian offer.<ref>{{cite web |url=http://www.janes.com/article/67273/philippines-evaluates-russian-kilo-class-submarines |title=Philippines evaluates Russian Kilo-class submarines |first=Jon |last=Grevatt |date=27 January 2017 |website=IHS Jane's Defence Industry |access-date=30 January 2017 |archive-url=https://web.archive.org/web/20170129212842/http://www.janes.com/article/67273/philippines-evaluates-russian-kilo-class-submarines |archive-date=29 January 2017 |url-status=dead}}</ref>

===Failed bids===
The [[Indonesian Navy]] was interested in purchasing two used Kilo-class submarines, but the [[Chief of Staff of the Indonesian Navy]] [[Laksamana]] [[Marsetio]] cancelled the plans in 2014 after inspecting the two submarines in Russia with an Indonesian Navy team. He said, "The submarines look good on the outside, but the inside is filled with broken equipment, and the two submarines have been in storage for two years." Indonesia instead bought six [[Jang Bogo-class submarine|Improved ''Jang Bogo''-class]] submarines, later known as {{sclass|Nagapasa|submarine|2}}, including a transfer of technology, where Indonesia will eventually build four of six of the submarines with South Korea.<ref>{{cite web |url=https://www.liputan6.com/news/read/2021855/tni-al-batal-beli-kapal-selam-rusia |title=TNI AL Batal Beli Kapal Selam Rusia |trans-title=Indonesian Navy cancels buying Russian submarines |first=Dian |last=Kurniawan |date=12 March 2014 |website=[[Liputan 6]] |language=id |access-date=25 March 2020}}</ref>
Actually, the bid for Kilo Russian submarines fell apart due to the lapse of the financing term of the Russian Federation.
