{{Weapons of mass destruction}}

The [[Russia|Russian Federation]] is known to possess or have possessed three types of [[weapons of mass destruction]]: [[nuclear weapon]]s, [[Biological warfare|biological weapons]], and [[Chemical warfare|chemical weapons]]. It is one of the five [[List of states with nuclear weapons|nuclear-weapon states]] recognized under the [[Treaty on the Non-Proliferation of Nuclear Weapons]] and one of [[List of nuclear triads|the four countries]] wielding a [[nuclear triad]].

{{As of|2025}}, Russia's triad of deployed [[strategic nuclear weapons]] includes approximately 1,254 [[Intercontinental ballistic missile|intercontinental ballistic missiles]], 992 [[Submarine-launched ballistic missile|submarine-launched ballistic missiles]], and 586 [[Air-launched cruise missile|cruise missiles]] or [[Unguided bomb|bombs]] for delivery by [[Tupolev Tu-160]] and [[Tupolev Tu-95|Tu-95]] [[Strategic bomber|bombers]]. It also possesses the world's largest arsenal of [[tactical nuclear weapons]], approximately 1,500, of various shorter-range missiles, and is the only country to maintain nuclear-armed [[Anti-aircraft warfare|anti-air]], [[Anti-ballistic missile|anti-ballistic]], and [[Anti-submarine weapon|anti-submarine weapons]].

===History===

====Soviet era====
{{main|Soviet atomic bomb project}}

==== Production sites ====
Three sites in the [[Russian Soviet Federative Socialist Republic|Russian SFSR]] and subsequently Russia produced 145 tons of [[weapons-grade plutonium]] (uncertainty ±8 tons) from 1948 to 2010, with a consistent production peak between 1967 and 1989. Following the Moscow test reactor [[F-1 (nuclear reactor)|F-1]] in 1946, the [[Mayak]] site in [[Chelyabinsk-40]] began construction. The first plutonium production reactor [[A-1 (nuclear reactor)|A-1]] began operation in 1948, fuelling the [[RDS-1]] test. The Mayak site received nine further reactors were constructed. Of these, four were used for plutonium production, the other six reactors primarily produced [[tritium]] for [[thermonuclear weapons]]. Plutonium was also produced by five reactors at the [[Siberian Chemical Combine]] in [[Tomsk-7]], and three reactors at the [[Mining and Chemical Combine]] in [[Krasnoyarsk-26]]. The last plutonium production reactor in Russia is believed to have shut down in 2010. Mayak continues to operate two reactors for tritium and industrial [[Radionuclide|radioisotope]] production.<ref>{{Cite journal |last=Diakov |first=Anatoli |date=2011-04-25 |title=The History of Plutonium Production in Russia |url=http://www.tandfonline.com/doi/abs/10.1080/08929882.2011.566459 |journal=Science & Global Security |language=en |volume=19 |issue=1 |pages=28–45 |doi=10.1080/08929882.2011.566459 |issn=0892-9882}}</ref>

Russian sites also produced 1,250 tons of [[highly enriched uranium]] (uncertainty ±120 tons) from 1949 to 2010, excluding HEU produced for [[Naval nuclear reactor|naval nuclear reactors]]. Of this, 500 tons was [[Downblending|downblended]] by the [[Megatons to Megawatts Program]], and a further hundred tons were used in production research reactors, nuclear tests, and other downblending programs. Russia is now believed to possess 656 tons between HEU stockpiles and HEU inside weapons themselves. This began with the [[SU-20]] [[electromagnetic separation]] plant, but the Soviet project quickly followed the Manhattan Project's [[gaseous diffusion]] scheme, constructing the [[D-1 gaseous diffusion plant|D-1]] plant in [[Sverdlovsk-44]], eventually becoming the [[Ural Electrochemical Combine]]. The D-1 plant could produce 0.01 million [[Separative work units|SWU]]/year. The development of the [[gas centrifuge]] and waves of modernizations brought the Ural Electrochemical Combine to 11.9 million SWU/year by 1993. Further enrichment plants were built at the Siberian Chemical Combine, the [[Zelenogorsk Electrochemical Plant]] and the [[Angarsk Electrochemical Combine]].<ref>{{Cite journal |last=Podvig |first=Pavel |date=2011-04-25 |title=History of Highly Enriched Uranium Production in Russia |url=http://www.tandfonline.com/doi/abs/10.1080/08929882.2011.566467 |journal=Science & Global Security |language=en |volume=19 |issue=1 |pages=46–67 |doi=10.1080/08929882.2011.566467 |issn=0892-9882}}</ref>

==== Testing ====
The Soviet Union used three major test sites: [[Semipalatinsk Test Site|Semipalatinsk]] in [[Kazakh Soviet Socialist Republic|Kazakhstan]], [[Novaya Zemlya]] in the extreme north, and [[Kapustin Yar]]. Notable tests at Semipalatinsk following RDS-1 include [[RDS-4]], the first Soviet [[tactical nuclear weapon]], [[RDS-6s]], the first Soviet weapon to use thermonuclear reactions in  a [[layer cake design]], sometimes called a [[boosted fission weapon]], and [[RDS-37]], the first Soviet true two-stage [[thermonuclear weapon]].<ref name=":0" /> Novaya Zemlya was the site of further megaton-range explosions, including the [[Tsar Bomba]], the largest weapon ever detonated, and the [[Raduga (nuclear test)|Raduga]] live test of an [[R-13 (missile)|R-13]] [[submarine-launched ballistic missile]]. Kapustin Yar was used for [[High-altitude nuclear explosion|high-altitude nuclear tests]] launched by missiles, including the [[1961 Soviet nuclear tests|1961 tests]] and [[Soviet Project K nuclear tests|Project K tests]]. The [[Soviet Army]] also conducted the [[Totskoye nuclear exercise]] in 1954. After the 1963 [[Partial Nuclear Test Ban Treaty]], underground testing continued at Semipalatinsk and Novaya Zemlya until 1990.<ref>{{Cite book |last=Zaloga |first=Steven J. |url=https://books.google.com/books?hl=en&lr=&id=yKpqBgAAQBAJ&oi=fnd&pg=PT6&dq=%2522rds-37%2522+%2522semipalatinsk%2522+%2522rds-6s%2522++%2522rds-4%2522&ots=N_i7vFbfsR&sig=5AdmsV-TAVftVTVvHktHcLGcCiQ |title=The Kremlin's Nuclear Sword: The Rise and Fall of Russia's Strategic Nuclear Forces 1945-2000 |date=2014-05-27 |publisher=Smithsonian Institution |isbn=978-1-58834-485-4 |language=en}}</ref> The Soviet Union also developed [[Clean bomb|"clean" thermonuclear weapons]], including weapons with only [[deuterium]] as thermonuclear fuel, used in a brief program of [[peaceful nuclear explosions]].<ref name="j500">{{cite web |title=Достояние России. |url=https://elib.biblioatom.ru/text/dostoyanie-rossii_2006/p38 |access-date=2025-06-17 |website=Электронная библиотека /// История Росатома |language=ru}}</ref><ref name="d842">{{cite web |title=На благо России.

====Post-Soviet era====

{{see also|Ukraine and weapons of mass destruction|Kazakhstan and weapons of mass destruction}}
Post-Soviet countries have signed a [[Succession, continuity and legacy of the Soviet Union|series of treaties and agreements to settle the legacy of the former Soviet Union]] multilaterally and bilaterally.

At the [[dissolution of the Soviet Union]] in 1991, Soviet nuclear weapons were deployed in four of the new republics: Russia, [[Ukraine]], [[Belarus]] and [[Kazakhstan]]. In May 1992, these four states signed the [[Lisbon Protocol]], agreeing to join the [[Treaty on the Non-Proliferation of Nuclear Weapons]], with Russia the [[continuator state]] to the Soviet Union as a nuclear state, and the other three states joining as non-nuclear states.

Ukraine agreed to give up its weapons to Russia, in exchange for guarantees of Ukrainian territory from Russia, the United Kingdom, and [[the United States]], known as the [[Budapest Memorandum on Security Assurances]]. [[China]] and [[France]] also made statements in support of the memorandum.<ref>{{cite news|url=https://www.voanews.com/a/the-budapest-memorandum-and-crimea/1862439.html|title=The Budapest Memorandum and Crimea|work=VOA News|date=March 2, 2014 |access-date=24 October 2014}}</ref>

=== Arms reduction ===
{{Main|Megatons to Megawatts Program}}

The threat of [[nuclear warfare]] was a persistent and terrifying threat during the [[Cold War]]. At its height, the Soviet Union and United States each mustered tens of thousands of warheads, under the doctrine of [[mutual assured destruction]]. By the 1980s, both the United States and Soviet Union sought to reduce the number of weapons the other was fielding. This led to the opening of arms reduction talks in 1982.<ref name="START I">{{Cite web |title=START I |url=https://www.nti.org/education-center/treaties-and-regimes/treaties-between-united-states-america-and-union-soviet-socialist-republics-strategic-offensive-reductions-start-i-start-ii/ |access-date=2022-03-01 |website= Nuclear Threat Initiative |language=en}}</ref>

This culminated in the signing of the [[START I]] treaty in 1991: the first nuclear arms reduction treaty between the two global powers. This first treaty limited the number of deployed warheads in each nation to 6,000, nearly halving the prior 10,000 to 12,000 being fielded in 1991.<ref name="START I"/> The considerable success of START I, combined with the [[dissolution of the Soviet Union]] in 1991, led to the [[START II]] treaty. Russia never ratified the treaty, and it did not go into effect. An attempted [[START III]] was attempted but could not get past negotiations.<ref>{{Cite web |title=START II |url=https://www.nti.org/education-center/treaties-and-regimes/treaty-between-united-states-america-and-union-soviet-socialist-republics-strategic-offensive-reductions-start-ii/ |access-date=2022-03-01 |website=Nuclear Threat Initiative |language=en}}</ref>

Instead, the [[Strategic Offensive Reductions Treaty]] was passed in 2002, capping warheads at 2,200.<ref>{{Cite web |title=SORT |url=https://www.nti.org/education-center/treaties-and-regimes/strategic-offensive-reductions-treaty-sort/ |access-date=2022-03-01 |website= Nuclear Threat Initiative |language=en}}</ref> The current limitations stem from the [[New START]] treaty, ratified in 2010. It limits each side to 1,550 weapons. Nuclear bombers only count as one weapon each, even though they may carry up to 20, so the actual limit on the countries is slightly higher.

During an annual [[Presidential Address to the Federal Assembly|state-of-the-nation address]] given on March 1, 2018, President [[Vladimir Putin]] publicly claimed that Russia was now in possession of several new classes of nuclear weapons, including some with capabilities previously speculated to exist. Putin discussed several new or upgraded weapons, including a [[Boost-glide|hypersonic glide vehicle]] known as the [[Avangard (hypersonic glide vehicle)|Avangard]], capable of performing sharp maneuvers while traveling at 20 times the speed of sound making it "absolutely invulnerable for any missile defense system."<ref>{{cite news |work=ABC News (US) |url=http://abcnews.go.com/International/wireStory/putin-boasts-russian-nuclear-weapons-53433951 |title=Putin boasts of new Russian nuclear weapons |access-date=15 January 2022 |archive-url=https://web.archive.org/web/20180301144604/http://abcnews.go.com/International/wireStory/putin-boasts-russian-nuclear-weapons-53433951 |archive-date=1 March 2018 |url-status=dead}}</ref>

Putin discussed the existence of a nuclear powered underwater torpedo and a nuclear powered [[cruise missile]] ([[9M730 Burevestnik]]), both with effectively unlimited range. He discussed that Russia had tested a new class of traditional [[Intercontinental ballistic missile|ICBM]] called the [[RS-28 Sarmat]], which expanded upon the range and carrying capability of the Soviet-era Satan ICBM. Animations of these weapons were shown in front of the live and televised audience. Putin suggested that an online poll be conducted to give them official public names.<ref>{{cite news|url=https://www.bbc.com/news/world-europe-43239331|title=Russia has 'invincible' nuclear weapons|work=BBC News|date=March 1, 2018}}</ref>

According to [[Ion Mihai Pacepa]], "[[Khrushchev]]'s nuclear-proliferation process started with Communist China in April 1955, when the new ruler in the Kremlin consented to supply [[Beijing]] a sample atomic bomb and to help with its mass production. Subsequently, the Soviet Union built all the essentials of China's new [[China and weapons of mass destruction#Nuclear weapons|military nuclear industry]]."<ref name="bomb">[http://article.nationalreview.com/?q=YmU3NjM4ZTg3NjViMTUyNWJmYWYzMDE4ZmRhOTQxZmI= Tyrants and the Bomb] {{webarchive|url=https://web.archive.org/web/20090606154259/http://article.nationalreview.com/?q=YmU3NjM4ZTg3NjViMTUyNWJmYWYzMDE4ZmRhOTQxZmI= |date=June 6, 2009 }} – by [[Ion Mihai Pacepa]], ''[[National Review]]'', October 17, 2006</ref>

Russia is one of the five "Nuclear Weapons States" (NWS) under the [[Treaty on the Non-Proliferation of Nuclear Weapons]] (NPT), which Russia ratified (as the [[Soviet Union]]) in 1968.

Following the dissolution of the Soviet Union in 1991, a number of Soviet-era nuclear warheads remained on the territories of [[Byelorussian Soviet Socialist Republic|Belarus]], [[Ukrainian Soviet Socialist Republic|Ukraine]], and [[Kazakh Soviet Socialist Republic|Kazakhstan]]. Under the terms of the [[Lisbon Protocol]] to the NPT, and following the 1995 Trilateral Agreement between Russia, Belarus, and the US, these were transferred to Russia, leaving Russia as the sole inheritor of the Soviet nuclear arsenal. It is estimated that the Soviet Union had approximately 45,000 nuclear weapons stockpiled at the time of its collapse, according to [[Viktor Mikhaylov (academic)|Viktor Mikhaylov]], head of the [[Federal Agency on Atomic Energy (Russia)]].<ref name="CISAC Manage Plutonium">{{multiref2

The collapse of the Soviet Union allowed for a warming of relations with NATO. Fears of a [[nuclear holocaust]] lessened. In September 1997, the former secretary of the Russian Security Council [[Alexander Lebed]] claimed 100 "suitcase sized" nuclear weapons were unaccounted for. He said he was attempting to inventory the weapons when he was fired by President [[Boris Yeltsin]] in October 1996.<ref>{{cite web|url=http://www.armscontrol.org/act/1997_09/lebedsept|title=Russian Officials Deny Claims Of Missing Nuclear Weapons|access-date=October 24, 2014}}</ref> Indeed, several US politicians have expressed worries and promised legislation addressing the threat.<ref>{{cite web|url=http://belfercenter.ksg.harvard.edu/publication/1010/nuclear_dangers.html?breadcrumb=%2F|title=Nuclear Dangers: Fear Increases of Terrorists Getting Hands on 'Loose' Warheads as Security Slips|date=October 19, 1997|access-date=October 24, 2014|archive-date=December 30, 2013|archive-url=https://web.archive.org/web/20131230234553/http://belfercenter.ksg.harvard.edu/publication/1010/nuclear_dangers.html?breadcrumb=%2F|url-status=dead}}</ref>

===Nuclear sabotage allegations===
The highest-ranking [[Glavnoye Razvedyvatel'noye Upravleniye|GRU]] defector [[Stanislav Lunev]] described alleged Soviet plans for using [[tactical nuclear weapons]] for [[sabotage]] against the United States in the event of war. He described Soviet-made [[suitcase nukes]] identified as RA-115s (or RA-115-01s for submersible weapons) which weigh {{convert|50|-|60|lb|kg}}. These portable bombs can last for many years if wired to an electric source. "In case there is a loss of power, there is a battery backup. If the battery runs low, the weapon has a transmitter that sends a coded message – either by [[satellite]] or directly to a [[GRU (Russian Federation)|GRU]] post at a [[List of diplomatic missions in Russia|Russian embassy or consulate]]."<ref name="Lunev">[[Stanislav Lunev]]. ''Through the Eyes of the Enemy: The Autobiography of Stanislav Lunev'', Regnery, 1998. {{ISBN|0-89526-390-4}}.</ref>

Lunev was personally looking for hiding places for weapons caches in the [[Shenandoah Valley]] area.<ref name="Lunev"/> He said that "it is surprisingly easy to smuggle nuclear weapons into the US" either across the [[Mexico–United States border|Mexican border]] or using a small transport missile that can slip though undetected when launched from a Russian airplane.<ref name="Lunev"/> Searches of the areas identified by Lunev – who admits he never planted any weapons in the US – have been conducted, "but law-enforcement officials have never found such weapons caches, with or without portable nuclear weapons" in the US.<ref>Steve Goldstein and Chris Mondics, "Some Weldon-backed allegations unconfirmed; Among them: A plot to crash planes into a reactor, and missing suitcase-size Soviet atomic weapons". ''Philadelphia Inquirer'' (15 March 2006) A7.</ref>

In a 2004 interview, colonel general of [[Strategic Missile Forces|RVSN]] [[Viktor Yesin]] said that Soviet small-scale nuclear bombs have only been operated by the Army. All such devices have been stored in a weapons depot within Russia, and only left it for checks at the plant which produced them.<ref>{{cite news |last1=Novikova |first1=Inna |title=Куда исчезли 'ядерные чемоданчики'? |url=https://military.pravda.ru/46851-sadm/ |work=[[Pravda]] |date=March 29, 2004 |language=ru}}</ref>

==Biological weapons==
{{Main|Soviet biological weapons program}}

The Soviet Union covertly operated the world's largest, longest, and most sophisticated biological weapons programs.<ref name="LeitenbergZilinskasKuhn2012"/> The program began in the 1920s and lasted until at least September 1992 but has possibly been continued by Russia after that.<ref name="LeitenbergZilinskasKuhn2012" /> Thereby, the Soviet Union violated its obligations under the [[Biological Weapons Convention]], which it had signed on April 10, 1972, and ratified on March 26, 1975.<ref>{{Cite web|title=Status of the Biological Weapons Convention|url=http://disarmament.un.org/treaties/t/bwc|access-date=2021-02-07|website=[[United Nations Office for Disarmament Affairs]]}}</ref>

In the early 1970s, the Soviet Union significantly enlarged its offensive biological weapons programs.<ref>Leitenberg, M., Zilinskas, R., & Kuhn, J. (2012). Beginnings of the “Modern” Soviet BW program, 1970–1977. In ''The Soviet Biological Weapons Program'' (pp. 51–78). Cambridge, Massachusetts; London, England: Harvard University Press. Retrieved February 7, 2021, from http://www.jstor.org/stable/j.ctt2jbscf.7</ref> After 1975, the program of biological weapons was run primarily by the "civilian" [[Biopreparat]] agency, although it also included numerous facilities run by the [[Ministry of Defense (Soviet Union)|Soviet Ministry of Defense]], [[Ministry of Agriculture and Food (Soviet Union)|Ministry of Agriculture]], [[Ministry of the Chemical Industry (Soviet Union)|Ministry of Chemical Industry]], [[Ministry of Health (Soviet Union)|Ministry of Health]], and [[Soviet Academy of Sciences]].<ref name="Alibek">Alibek, K. and S. Handelman. Biohazard: The Chilling True Story of the Largest Covert Biological Weapons Program in the World– Told from Inside by the Man Who Ran it. Delta (2000) {{ISBN|0-385-33496-6}}</ref>

According to [[Ken Alibek]], who was deputy-director of [[Biopreparat]], the Soviet biological weapons agency, and who defected to the United States in 1992, weapons were developed in labs in isolated areas of the Soviet Union including mobilization facilities at [[Omutninsk]], [[Penza]] and [[Pokrov, Vladimir Oblast|Pokrov]] and research facilities at [[Moscow]], [[Stirzhi]] and [[Vladimir, Russia|Vladimir]]. These weapons were tested at several facilities most often at "Rebirth Island" ([[Vozrozhdeniya]]) in the [[Aral Sea]] by firing the weapons into the air above monkeys tied to posts, the monkeys would then be monitored to determine the effects. According to Alibek, although Soviet offensive program was officially ended in 1992, Russia may be still involved in the activities prohibited by BWC.<ref name="Alibek"/>

In 1993, the story about the [[Sverdlovsk anthrax leak]] was published in Russia. The incident occurred when [[spore]]s of [[anthrax]] were accidentally released from a military facility in the city of Sverdlovsk (formerly, and now again, [[Yekaterinburg]]) {{convert|1500|km|abbr=on}} east of Moscow on April 2, 1979. The ensuing outbreak of the disease resulted in 94 people becoming infected, 64 of whom died over a period of six weeks.<ref name="Alibek"/>

In 2022 Russian Ministry of Defense started construction of a new massive facility at Sergiev Posad-6 site that hosted bioweapons research in Soviet times.<ref>{{Cite web |title=Satellite images show major expansion at Russian site with secret bioweapons past |url=https://www.washingtonpost.com/national-security/interactive/2024/russia-biological-chemical-weapons-laboratory-expansion/ |website=The Washington Post}}</ref> The site belonging to [[48th Central Scientific Research Institute]] (48 ЦНИИ) of the Russian Ministry of Defense, featuring biological security labs was even featured on Russian TV when a delegation from the ministry, then led by Sergei Shoigu visited it.<ref>{{Cite news |last=Krutov |first=Mark |last2=Dobrynin |first2=Sergei |date=2024-12-17 |title=Inside A Secret, Expanding Russian Lab Site With A Bioweapons Legacy |url=https://www.rferl.org/a/russia-biological-weapons-laboratory-sergiyev-posad-shoigu-visit/33236030.html |access-date=2024-12-17 |work=Radio Free Europe/Radio Liberty |language=en}}</ref> Also in 2022 the 48th Institute has registered a patent for "protective medium for freeze-drying of [[Yersinia pestis]]", a common biological weapon pathogen.<ref>{{Cite web |title=RU2800372C1 – ПРОТЕКТИВНАЯ СРЕДА ДЛЯ СУБЛИМАЦИОННОГО ВЫСУШИВАНИЯ КЛЕТОК Y.

As of 2024, the [[United States Department of State]] "assesses that the Russian Federation (Russia) maintains an offensive [biological weapons] program and is in violation of its obligation under Articles I and II of the BWC. The issue of compliance by Russia with the BWC has been of concern for many years."<ref>{{cite web |url=https://www.state.gov/wp-content/uploads/2024/04/2024-Arms-Control-Treaty-Compliance-Report.pdf |title=2024 Arms Control Treaty Compliance Report |date=April 2024 |publisher=U.S. Department of State |access-date=2024-11-01}}</ref>

==Chemical weapons==

Russia signed the [[Chemical Weapons Convention]] on January 13, 1993, and ratified it on November 5, 1997. Russia declared an arsenal of 39,967 tons of [[Chemical warfare|chemical weapons]] in 1997 consisting of:
*[[blister agent]]s: [[Lewisite]], [[mustard gas|mustard]], Lewisite-mustard-mix (HL)
*[[nerve agent]]s: [[Sarin]], [[Soman]], [[VX (nerve agent)|VX]]

[[Ratification]] was followed by three years of inaction on chemical weapons destruction because of the [[August 1998 Russian financial crisis]].

Russia met its treaty obligations by destroying 1% of its chemical agents by the Chemical Weapons Convention's 2002 deadline,<ref>{{Cite web|url=http://www.opcw.org/html/global/ra_frameset.html|archive-url=https://web.archive.org/web/20040406043031/http://www.opcw.org/html/global/ra_frameset.html|title=Recent Updates|archive-date=April 6, 2004}}</ref> but requested technical and financial assistance and extensions on the deadlines of 2004 and 2007 due to the environmental challenges of chemical disposal. This extension procedure spelled out in the treaty has been utilized by other countries, including the [[United States and weapons of mass destruction#Chemical weapons disposal|United States]].

In 1947 the 76th warehouse at Leonidovka, Penza District ([[:ru:Леонидовка_(железнодорожная_станция,_Пензенская_область)]]) was reorganized into the 608th Central Aviation Ammunition Base. In 1983, the base was renamed the 50th Arsenal of the Air Force. In February 1998, the unit was reassigned to the Chief of the NBC Protection Troops and received the name 50th Arsenal for Storage of Chemical Weapons of the 1st Category. In 2001, Military Unit 21222 became part of the [[Federal Directorate for the Safe Storage and Destruction of Chemical Weapons]] and was named the Leonidovka Chemical Weapons Storage Facility. The depot was storing aviation chemical munitions filled with nerve agents such as sarin, [[Soman]], and [[VX (nerve agent)|VX]]. The toxic agents stored there amounted to 17.2% of the total stockpiles in the Russian Federation.<ref>{{Cite web |title=Воинской части в Леонидовке исполнилось 80 лет |url=https://russia58.ru/news/76683/ |access-date=2025-07-22 |website=russia58.ru}}</ref>
