===History===

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

==== Production sites ==== Three sites in the 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 in 1946, the Mayak site in Chelyabinsk-40 began construction. The first plutonium production 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 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|url-access=subscription }}</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 reactors. Of this, 500 tons was 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 plant in Sverdlovsk-44, eventually becoming the Ural Electrochemical Combine. The D-1 plant could produce 0.01 million 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|url-access=subscription }}</ref>

====Post-Soviet era==== {{main|Succession, continuity and legacy of the Soviet Union#Nuclear weapons}}

{{see also|Ukraine and weapons of mass destruction|Kazakhstan and weapons of mass destruction}} Post-Soviet countries have signed a 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>

==== Alleged Russian nuclear testing ==== The US alleged in 2020 that Russia had carried out "nuclear weapons experiments that have created nuclear yield" between 1996 and 2019, but that it was not aware of such individual experiments in 2019. As Russia is a signatory of the Comprehensive Nuclear-Test-Ban Treaty, but the treaty is not in force, the legal status of such an experiment is unclear. The same report accused China's nuclear weapons program of constructing the infrastructure for undetectable low-yield tests, but did not allege any tests had occurred.<ref name="i508">{{cite web |title=Executive Summary on Findings On Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments, April 2020 |url=https://s.wsj.net/public/resources/documents/EXECUTIVE%20SUMMARY%20OF%202020%20CR%20FINDINGS%2004.14.2020.pdf?mod=article_inline |access-date=2025-01-16}}</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.

Following the dissolution of the Soviet Union in 1991, a number of Soviet-era nuclear warheads remained on the territories of Belarus, Ukraine, and 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, head of the Federal Agency on Atomic Energy (Russia).<ref name="CISAC Manage Plutonium">{{multiref2 | 1 = {{citation |author1=((Committee on International Security and Arms Control)) |title= Management and Disposition of Excess Weapons Plutonium |date=January 15, 1994 |publisher=National Academies Press |location=Washington, DC |isbn=978-0-309-05042-5 |ref=none |url=https://books.google.com/books?id=IYEOUEgYhloC |access-date=14 December 2023 |language=en |quote=...{{nbsp}}Victor Mikhailov, head of the Russian Ministry of Atomic Energy (MINATOM), reportedly indicated that the Russian{{nbsp}}...

===Nuclear sabotage allegations=== The highest-ranking 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 post at a 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 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 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>

=== Cultural impact === Following the expansion of the Russian Orthodox Church following the dissolution of the Soviet Union, an eschatalogical-political concept called Nuclear Orthodoxy gained some prominence. Nuclear Orthodoxy was further elaborated upon by Eurasianist ideologue Yegor Kholmogorov in 2009, where he argued that Russia must secure dominance over the West through military methods and nuclear blackmail. The same year, Patriarch Kirill of Moscow visited the city of Sarov, home to the All-Russian Scientific Research Institute of Experimental Physics and birthplace of Saint Seraphim of Sarov, where he said that Russia's nuclear weapons programme was the will of God.<ref name="Sumlenny">{{Cite web |last=Sumlenny |first=Sergej |date=11 October 2022 |title=How Russia Learned to Love the Bomb (Too Much) |url=https://cepa.org/article/how-russia-learned-to-love-the-bomb-too-much/ |access-date=30 January 2024 |website=Center for European Policy Analysis}}</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 Soviet Ministry of Defense, Ministry of Agriculture, Ministry of Chemical Industry, 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 and research facilities at Moscow, Stirzhi and 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 spores 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"/>

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.

==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 weapons in 1997 consisting of: *blister agents: Lewisite, mustard, Lewisite-mustard-mix (HL) *nerve agents: Sarin, Soman, 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.

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.
