The collapse of the Soviet Union in December 1991 left the Russian Federation in possession of the vast majority of the USSR's weapons of mass destruction (WMD) complex. Since then, Russia has implemented arms control agreements and participated in threat reduction programs that have dismantled and downsized substantial parts of its arsenals and made inventory numbers more transparent. At present, Russia is modernizing and recapitalizing its entire arsenal of strategic nuclear weapons and delivery systems. Although the retirement of aging Soviet-era capabilities provides much of the impetus for these efforts, Russia also views modernization as a means to counteract the conventional superiority of the North Atlantic Treaty Organization (NATO), as well as a way to retain its status as a major military power. Given its extensive WMD capabilities, Russia's active participation in nonproliferation, arms control, and disarmament efforts is a prerequisite to their global success.
The Soviet nuclear weapons program began during World War II and culminated in a successful nuclear test in 1949. Russia, as the successor of the Soviet Union, is a nuclear weapon state party to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and one of the three NPT depository states.  According to estimates by the Natural Resources Defense Council (NRDC), by 1991 the Soviet Union had approximately 35,000 nuclear weapons in its stockpile, down from a peak in 1986 of approximately 45,000. 
Under the provisions of the 1991 Strategic Arms Reduction Treaty (START), the 2002 Strategic Offensive Reductions Treaty (SORT, also known as the Moscow Treaty), and the New START Treaty, Russia and the United States will be limited to 1,550 strategic warheads by 2018. According to the latest biannual exchange of data required under the New START Treaty, both the United States and Russia have met that goal. Russia has 1,444 warheads on 527 deployed intercontinental ballistic missiles (ICBM), submarine-launched ballistic missiles (SLBM), and warheads designated for heavy bombers.  However, Moscow's current total stockpile of deployed and non-deployed strategic and tactical nuclear weapons, including those awaiting dismantlement, is approximately 7,000 warheads. 
Russia inherited a massive nuclear weapons production complex and large stocks of weapons-grade fissile material after the collapse of the Soviet Union. It is estimated that Russia currently has 679 ± 120 metric tons of weapons grade-equivalent highly enriched uranium (HEU) and approximately 128 ± 8 tons metric tons of military-use plutonium.  In the early 1990s, the United States and Russia partnered through the Cooperative Threat Reduction (Nunn-Lugar) Program to secure Russian stockpiles of HEU and plutonium as well as to dismantle Soviet-era delivery systems and chemical weapons. However, since June 2013 the Russian government has allowed many of these cooperative agreements to expire, due in part to deteriorating relations with the United States. 
The Soviet Union began field trials with biological weapons agents in the mid-1920s, and launched a full-scale offensive biological warfare (BW) program in 1928.  The Soviet Union signed the Biological and Toxin Weapons Convention (BTWC) in 1972 and ratified it in 1975 as one of the treaty's three depository states.  However, the Soviet Union immediately violated the terms of the BTWC by reorganizing, greatly expanding, and modernizing its existing offensive BW program. The post-1973 Soviet offensive anti-personnel BW program, codenamed Ferment, sought to employ genetic engineering techniques to develop enhanced pathogens for use against humans.  Soviet BW scientists also continued to research, develop, and produce anti-crop and anti-livestock agents under a program codenamed Ekologiya. 
The USSR developed anti-personnel type-classified weapons around numerous pathogens, namely the causative agents of anthrax, brucellosis, glanders, Marburg fever, melioidosis, plague, Q fever, smallpox, tularemia, and Venezuelan Equine encephalitis.  The associated delivery systems included cluster submunitions for aerial cluster bombs and airplane spray tanks. 
Although Russia admitted the existence of the Soviet offensive BW program in 1992, the program’s full extent was never disclosed, and it remains unclear whether Russia fulfilled its obligations under Article I of the BTWC to fully eliminate or convert to peaceful use all of its components. 
During the Cold War, the Soviet Union developed the world's largest arsenal of chemical weapons, including artillery shells, bombs, and missiles that contained choking agents (phosgene); nerve-agents (sarin, soman, and VX); and blister agents (mustard, Lewisite, and mustard-lewisite mixture).  There have been allegations that the Soviet Union developed a new class of nerve agents (Novichok), estimated to be between 5 and 10 times more toxic than VX. 
Russia inherited the declared Soviet stockpile of 40,000 metric tons of CW munitions and agents stored in bulk.  In November 1997 Russia ratified the Chemical Weapons Convention (CWC), but financial and other difficulties impeded to the timely destruction of its chemical weapons stockpile. In September 2017 the OPCW announced that Russia had completed the full destruction of its CW stockpile.  Despite this declaration, Russia has been implicated in the March 2018 attempted assassination of former Russian intelligence officer Sergei Skripal and his daughter Yulia in the United Kingdom, which an OPCW-accredited lab in the UK determined involved a Novichok-class nerve agent. 
Russia has one of the most robust and advanced missile programs in the world, and maintains the capability to produce highly sophisticated liquid- and solid-propelled missiles of all ranges. Russia is a member of the Missile Technology Control Regime (MTCR) and the Hague Code of Conduct Against Ballistic Missile Proliferation (HCOC).
According to the latest New START data exchange, Russia deploys its 1,444 warheads on 527 strategic nuclear delivery systems.  Soviet legacy missile systems comprise 34% of the Russian missile arsenal.  Current modernization plans call for the elimination of these legacy missile systems by 2026; however, Russia’s current economic problems may affect this timeline.  For the land based leg of the nuclear triad Russia currently only produces the RS-24 Yars (NATO: SS-29) road mobile ICBM. Russia is currently developing two new ICBMs: a road mobile ICBM, the RS-26 Rubezh and a heavy liquid-fueled ICBM, called Sarmat. Development of a third, rail-mobile ICBM, called Barguzin, was suspended in December 2017 in order to focus resources on the Sarmat and Rubezh programs.  The RS-26’s entry into force has faced repeated delays and Sarmat is scheduled to enter service in 2019-2020.  The RS-26 has raised concerns within the United States and among its NATO allies given the fact Russia has flight tested the missile to ranges within those proscribed by the Intermediate-Range Nuclear Forces (INF) Treaty.  However, Russia did test the RS-26 beyond INF-prohibited ranges in May 2012, qualifying the missile as an ICBM counted under New START and therefore not subject to the INF. 
For its sea-based deterrent Russia currently deploys 12 submarines of 3 different classes, each carrying a different model of submarine-launched ballistic missile (SLBM). To replace the oldest submarines, Russia is building new Borey-class submarines.  Three of these submarines have entered service, and five more are under construction.  The SLBM carried by the Borey-class, the R-30 Bulava (NATO: SS-NX-30), suffered a difficult and protracted development period, with problems surfacing even after its de facto entry into service in 2012. Recent tests, however, have been generally successful. 
Russia's air-launched strategic nuclear weapons are the Kh-55 (NATO: AS-15 'Kent') and KH-102 air-launched cruise missiles (ALCM), deployed on Tu-95MS (Bear H) and Tu-160 (Blackjack) bombers.  Russia is currently designing a new long-range bomber, called the PAK-DA, which will eventually take over the roles of the Tu-95MS, the Tu-160 and the Tu-22 non-strategic bomber. The PAK-DA's first flight was scheduled for 2019, with entry into service in 2023, but Russia has announced its intention to restart Tu-160 production, with the PAK-DA's first flight slipping to 2021 and production starting several years later. 
Russia has also developed, and possibly deployed, a controversial ground-launched cruise missile (GLCM), reportedly named the 9M729.  In its annual Compliance Report released in July 2014, the U.S. State Department determined Russia had tested a GLCM in violation of the INF Treaty, which obligates the United States and Russia "not to possess, produce, or flight-test" missiles with maximum ranges between 500 and 5,500 km.  This claim has been reiterated in subsequent annual reports.  U.S. officials raised the issue both publicly and privately with their Russian counterparts, and called for a meeting of the INF's Special Verification Commission (SVC) in 2016. This SVC meeting, the first since 2003, was held in November 2016; no information is available regarding what was discussed, and it is not known if the issue was resolved.  On 8 December 2017, the United States announced that Russia was in violation of the INF Treaty, and that new sanctions will be put in place against the Russian companies that assisted in production of the new missiles that were reportedly deployed in February. 
During his State of the Nation address on 1 March 2018, Vladimir Putin revealed a variety of developmental weapons programs, including new strategic nuclear delivery systems, such as a nuclear-powered intercontinental cruise missile, a nuclear-capable underwater drone, and a hypersonic boost-glide vehicle. 
 The United States and the United Kingdom are the other two NPT depository states.
