The Kilo-class submarines are a group of diesel-electric attack submarines designed by the Rubin Design Bureau<ref name=fsgtd>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=ppu>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=diplomat20191122/> in the Soviet Union in the 1970s and built originally for the Soviet Navy.

The first version had the Soviet designation Project 877 Paltus (Template:Langx, meaning "halibut"), NATO reporting name Kilo.<ref name="TG14102024">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They entered operational service in 1980 and continued being built until the mid-1990s, when production switched to the more advanced Project 636 Varshavyanka variant, also known in the West as the Improved Kilo class.<ref>Gardiner, Chumbley and Budzbon (1995), pp. 408-409.</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Darman (2004), p. 46.</ref> The design was updated again by the Russian Navy in the mid-2010s, to a variant called Project 636.3, also known as Improved Kilo II.<ref name="TG14102024" />

Role

The Project 877 attack submarines were mainly intended for anti-shipping and 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 Template:Cvt and surface vessels with 10 Pa/Hz noisiness in Template:Cvt.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The improved sonar systems have reduced the number of operators needed by sharing the same console via automation.

Anechoic tiles 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>{{#invoke:citation/CS1|citation |CitationClass=web }}</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, Template:Ship Alrosa, is equipped with pump-jet propulsion, instead of a propeller.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It has been retrofitted for the Kalibr missile.<ref name="newdick">Template:Cite news</ref>

It was planned for Project 636 (Improved Kilo) to be succeeded by the Template:Sclass2 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.Template:Cn Series production was reported to be underway in the latter 2010s.<ref>Template:Cite news</ref>Template:Update after

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>{{#invoke:citation/CS1|citation |CitationClass=web }}</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>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The PPK 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 PPK class has a seven-bladed propeller, instead of the six-bladed propeller of the Project 877 class.<ref name=newdick/>

Operational history

Kilo-class attack submarines originally began entering service with the Soviet Navy from 1980.Template:Citation needed

At the beginning of 2014, the Chinese PLA Navy held an emergency combat readiness test.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</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 Template:Convert 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>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</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/> On 8 December 2015 marked the first time a Kilo-class submarine fired cruise missiles against an enemy. B-237 Rostov-on-Don struck two targets near the ISIS capital of Raqqa by the missile attack.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The B-237 Rostov-on-Don transited the Dardanelles on its way back to the Black Sea on 12 February 2022.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

B-871 Alrosa, a pump-jet Kilo class, which derives from the Project 877 hull, participated in the Russo-Ukraine War.

After the sinking of the Template:Ship in April 2022, it was remarked that the Kilo-class subs were the only members of the Black Sea Fleet whose orders did not prohibit venturing into Ukrainian waters near Odesa during the Russian invasion of Ukraine.<ref>Template:Cite news</ref> In September 2022, after the early 2022 Crimea attacks, the UK Ministry of Defence said that the Kilo-class submarines were moved from Sevastopol to the Port of Novorossiysk in Krasnodar Krai.<ref>Template:Cite news</ref><ref name="sutton">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On 13 September 2023, B-237 Rostov-on-Don was severely damaged by a Ukrainian Storm Shadow missile strike while it was drydocked in Sevastopol.<ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> According to satellite images taken in June 2024, the submarine was moved to a lesser used dry dock within the port (at coordinates 44.609975029014116, 33.537496816089906). Camouflage nets were, at least initially, thrown up to disguise its presence and to make observation more challenging. According to reports, the submarine is under repair.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On 2 August 2024, Ukrainian Forces launched a strike against a Russian submarine and an S-400 air defense system in Crimea. Ukrainian sources claimed that the submarine B-237 Rostov-on-Don was "sunk on the spot" in the attack.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Other sources claim that the submarine was only hit and not sunk.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Satellite images showed the that camouflage nets were burned out by the strike.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Operators

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>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

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>{{#invoke:citation/CS1|citation |CitationClass=web }}</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 Improved Jang Bogo-class submarines, later known as Template:Sclass, including a transfer of technology, where Indonesia will eventually build four of six of the submarines with South Korea.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Actually, the bid for Kilo Russian submarines fell apart due to the lapse of the financing term of the Russian Federation.
