The Soviet and Russian Nuclear Weapons Program: A Look at its History, Capabilities, and Doctrine
The Soviet and Russian Nuclear Weapons Program: A Look at its History, Capabilities, and Doctrine
1. Introduction
This report takes a look at the history and current state of the Soviet and, later, Russian nuclear weapons program. We'll explore its beginnings, the key people involved (both scientists and politicians), the major role espionage played, significant milestones in development, how the nuclear arsenal changed over time, its current strategic and non-strategic power, the impact of arms control treaties, ongoing updates, and the official ideas guiding its potential use. The focus here is on getting the technical facts right and providing an objective picture, steering clear of political opinions, to give a solid understanding of one of the world's major nuclear powers and its place in global strategy.
2. How the Soviet Nuclear Program Started
Early Research (Before and Early WWII): Soviet physicists were already deep into nuclear and atomic research long before World War II. By 1939, based on international discoveries like fission, they knew a nuclear chain reaction was theoretically possible. Places like the Radium Institute and the Leningrad Physico-Technical Institute (FTI) were hubs for this work, even having cyclotrons. Seeing the potential, the Soviet Academy of Sciences set up a "Committee for the Problem of Uranium" in June 1940 to look into fission and uranium sources.
Wartime Interruption: The German invasion in June 1941 stopped much of this basic research cold. Scientists and resources shifted to urgent wartime needs like radar and naval mines. Still, some physicists kept thinking about nuclear potential. Georgy Flerov noticed Western scientists weren't publishing on nuclear fission anymore and suspected they were secretly building a powerful new weapon. In April 1942, Flerov wrote straight to Joseph Stalin, pushing him to start a Soviet atomic bomb project immediately. This warning, plus early intelligence from the UK, laid the groundwork, though it started small compared to the American Manhattan Project.
Key Scientific Figures: Several scientists were crucial:
Igor V. Kurchatov: Often called the "father" of the Soviet bomb, he became the technical director in late 1942. He set up Laboratory No. 2 near Moscow. Intelligence about plutonium shifted his focus there. Kurchatov oversaw the first Soviet nuclear reactor (critical in late 1946) and directed the first atomic test (RDS-1) in 1949. He was also key in the early hydrogen bomb work (RDS-6s).
Yulii B. Khariton: Having worked with Rutherford and Chadwick in Cambridge, Khariton was brought in by Kurchatov. In 1946, he became scientific director of the secret weapons lab KB-11 (Arzamas-16) near Sarov. Working with Yakov Zeldovich on theory, Khariton led the design and building of the first fission bomb (RDS-1) and later thermonuclear devices. His vital role wasn't widely known in the West until after the USSR fell.
Yakov B. Zeldovich: A highly productive physicist, Zeldovich worked with Khariton on early fission chain reaction theories (1939-41). He was essential in setting up Arzamas-16 and did crucial calculations there on nuclear combustion. He also contributed significantly to the thermonuclear program alongside his other physics work.
Andrei D. Sakharov: Joining later, Sakharov was central to the Soviet H-bomb. He came up with the "Sloika" (Layer Cake) design, tested as RDS-6s. More importantly, he later developed the "Third Idea"—using radiation from a primary fission blast to compress and ignite a secondary fusion stage, similar to the US Teller-Ulam design. This was the basis for the first successful Soviet two-stage H-bomb test, RDS-37.
Impact of WWII and Post-War Push: During WWII, the Soviet nuclear effort was small, maybe just a few dozen scientists. The fight against Germany took priority, and an atomic weapon seemed far off.
The Game Changer: The US bombings of Hiroshima and Nagasaki in August 1945 changed everything. Seeing the bomb's power and the US monopoly spurred Stalin into action. On August 20, 1945, he ordered a massive crash program, making it the nation's top priority. A Special Committee, led by security chief Lavrentiy Beria, took charge. Beria was effective, though brutal. The state threw everything into it, including forced labor from the Gulags for mining and construction. The Cold War's start only increased the urgency for the USSR to catch up with the US nuclear capability.
The Role of Spies: Soviet spying on Allied nuclear work (codenamed ENORMOZ) started around 1941, helped by sources like the "Cambridge Five" in Britain. But the most vital information came from spies inside the US Manhattan Project, including physicists Klaus Fuchs and Theodore Hall, and machinist David Greenglass. George Koval's role also emerged later.
Klaus Fuchs: A German-born British physicist at Los Alamos, Fuchs provided incredibly detailed information due to his access and technical skill. He gave data on uranium separation, plutonium production, the crucial implosion mechanism for plutonium bombs, critical mass calculations, initiator design, weapon dimensions, production rates, the Trinity test, and even early US H-bomb ideas.
Theodore Hall: A young American physicist at Los Alamos, Hall independently confirmed details about the plutonium implosion bomb ("Fat Man"), plutonium purification, and how Los Alamos was organized.
Impact of Espionage: This intelligence was priceless. While Soviet scientists like Khariton still had to verify and build things, the spy data provided a proven blueprint. Knowing the American plutonium implosion design worked let the Soviets, under pressure from Stalin and Beria for quick results, focus their efforts and skip potentially long and costly research on other designs (like a uranium gun-type bomb) or less efficient enrichment methods. As a result, the first Soviet bomb, RDS-1, was an exact copy of the American "Fat Man". This strategic shortcut, providing validation and direction, was arguably as important as the technical details themselves. Estimates suggest spying sped up the Soviet bomb project by six months to two years, maybe more, saving vital time and resources. The successful program was a mix of Soviet scientific talent, organizational skill (like Kurchatov's leadership and labs like Lab No. 2 and Arzamas-16), and critically important espionage.
3. Development Milestones and Timeline
First Atomic Bomb Test (RDS-1 / "Joe-1"): The intense post-war push culminated on August 29, 1949, at 7:00 AM local time. At the Semipalatinsk Test Site in Kazakhstan, the Soviet Union detonated its first nuclear device. Officially RDS-1 (possibly for "Stalin's Rocket Engine") and internally "First Lightning," the US called it "Joe-1" after Joseph Stalin. It was a plutonium implosion bomb, a copy of the US "Fat Man" based on spy intelligence. It yielded about 22 kilotons (kt). US reconnaissance aircraft detected the fallout, shocking the West by ending the US nuclear monopoly years sooner than expected. This dramatically ramped up the Cold War arms race.
Early Thermonuclear Work (RDS-6s / "Joe-4"): After RDS-1, the focus shifted to the hydrogen bomb. Early work by Zeldovich and Sakharov led to Sakharov's "Sloika" (Layer Cake) design, RDS-6s. This wasn't a true two-stage H-bomb, but a single-stage boosted fission device using layers of fissionable material (U-235 core, U-238 layers) and solid fusion fuel (Lithium-6 Deuteride, LiD). Tested on August 12, 1953, at Semipalatinsk ("Joe-4" to the US), it yielded 400 kt. Much of the yield (70-75%) came from fissioning the U-238 layers, with fusion contributing 15-20% and the primary core about 10%. Although not scalable like the huge US "Mike" device (1952), RDS-6s was designed to be deliverable by aircraft. Moscow claimed a usable H-bomb, briefly seeming ahead of the US. However, fallout analysis confirmed its single-stage nature. The Sloika design was a dead end for high yields but gave valuable experience. A tritium-free version, RDS-27, was tested in November 1955 (250 kt).
First Two-Stage H-Bomb Test (RDS-37 / "Joe-19"): The breakthrough to a true, scalable H-bomb came with RDS-37, based on Sakharov's "Third Idea" – radiation implosion, similar to the US Teller-Ulam design. This used X-rays from a primary fission blast to compress and ignite a secondary fusion stage with LiD. Tested November 22, 1955, at Semipalatinsk, RDS-37 had a design yield of ~3 megatons (Mt) but was tested at 1.6 Mt. In a world first, it was air-dropped from a Tu-16 "Badger" bomber and detonated at 1,550 meters. This success showed Soviet mastery of high-yield thermonuclear principles, closing the H-bomb gap with the US and setting the design basis for future warheads. The test tragically caused damage and casualties far from ground zero due to an unexpected atmospheric inversion. The rapid progress from 1949 (fission) to 1953 (boosted fission) to 1955 (two-stage H-bomb) highlighted the Soviet program's speed and capability.
Developing Delivery Systems: Alongside warheads, the USSR built ways to deliver them:
Strategic Bombers: The first was the Tupolev Tu-4 "Bull" (1949), a copy of the US B-29. Jet bombers followed quickly. The Tu-16 "Badger" (first flight 1952, service ~1954) was a medium bomber that dropped the RDS-37. The main bomber became the Tu-95 "Bear" (first flight 1952, service 1956). This large, four-engine plane used turboprops for long range and heavy payload needed for early, bulky bombs. The Tu-95 lasted exceptionally long, carrying bombs and later cruise missiles; updated versions (Tu-95MS/MSM) are still in service. A modified Tu-95 dropped the Tsar Bomba (largest ever tested) in 1961. The supersonic Tu-160 "Blackjack" entered service later, in 1987.
Intercontinental Ballistic Missiles (ICBMs): The R-7 "Semyorka" (SS-6 Sapwood) was the world's first ICBM. Design started in 1953 to deliver heavy H-bombs globally. The first successful full-range test was August 21, 1957. An R-7 launched Sputnik 1 on October 4, 1957. The R-7 (~8,800 km range) and R-7A (~12,000 km) became operational in 1960. However, the R-7 system was large, vulnerable, and used difficult cryogenic fuels, limiting its practicality. This pushed development towards silo-based and mobile ICBMs.
Submarine-Launched Ballistic Missiles (SLBMs): Early capability came from the R-11FM (SS-N-1 Scud-A/SS-1b Scud), a naval Scud version. The first launch from a surfaced diesel-electric Zulu IV sub was September 16, 1955. These became operational in 1959 on Zulu V and Golf class subs (SSBs). But the R-11FM had short range (~150 km) and required surfacing, making the sub vulnerable. The first nuclear-powered ballistic missile sub (SSBN) was the K-19 (Hotel class), commissioned November 1960. It carried only three R-13 (SS-N-4) missiles and also had to surface. The first successful submerged launch was September 10, 1960, and operational submerged launch came with the R-21 (SS-N-5) in 1963. A big leap was the Yankee class SSBN (Project 667A) in 1967, comparable to the US Polaris fleet, carrying 16 SLBMs.

4. The Soviet Nuclear Arsenal at its Height
The Soviet stockpile peaked in the mid-1980s after four decades of intense Cold War production. Estimates put the total around 45,000 warheads (strategic and non-strategic) in 1986, though some suggest closer to 39,000-40,000. Either way, it significantly outnumbered the US peak. This arsenal included:
Strategic Forces: Roughly 10,000-11,000 warheads on ICBMs, SSBNs, and bombers designed to hit the enemy's homeland.
Non-Strategic (Tactical) Forces: The majority, estimated at 28,000 to over 34,000 warheads. These were for theater use (mainly Europe) and included artillery shells, short-range missiles, tactical bombs, naval weapons (torpedoes, depth charges), and air defense missiles. They were spread across Soviet territory and, until the late 80s, in Eastern European Warsaw Pact nations.
Delivery systems at the peak included advanced tech:
ICBMs: Heavy, liquid-fueled, silo-based missiles with Multiple Independently Targetable Re-entry Vehicles (MIRVs), like the R-36M/R-36M2 (SS-18 Satan) and UR-100N UTTH (SS-19 Stiletto). The mid-80s also saw the first solid-fueled, road-mobile ICBMs like the RT-2PM Topol (SS-25 Sickle) for better survivability. The rail-mobile RT-23 UTTH (SS-24 Scalpel) also started deployment late 80s.
SLBMs: Key subs included Delta III class (Project 667BDR) carrying MIRVed R-29R (SS-N-18) missiles. The huge Typhoon class (Project 941), the largest subs ever, carried solid-fueled, MIRVed R-39 (SS-N-20) missiles. The Delta IV class (Project 667BDRM), entering service mid-80s, carried the advanced liquid-fueled, MIRVed R-29RM (SS-N-23 Skiff), later upgraded.
Bombers: The Tu-95MS (Bear H) turboprop carried the Kh-55 (AS-15 Kent) long-range Air-Launched Cruise Missile (ALCM). The supersonic, variable-geometry Tu-160 (Blackjack) started service in 1987, also mainly with ALCMs.
This mid-80s peak showed not just numerical strength (especially non-strategic weapons for potential European conflict) but also technological maturity with MIRVs, solid fuels, mobile basing, and cruise missiles. This height occurred just as internal changes under Gorbachev and economic pressures paved the way for serious arms control talks, leading to reductions.
5. Russia's Current Nuclear Capabilities (as of early 2024/2025)
After the USSR dissolved in 1991, Russia inherited most of the nuclear arsenal. Arms control and aging systems led to big cuts, but Russia still maintains a large, diverse, and actively modernizing nuclear force.
Estimated Stockpile Size: Exact numbers are secret, but analyses (like FAS, SIPRI) suggest for early 2024/2025:
Total Inventory: Largest globally. FAS estimated ~5,580 total warheads (early 2024), including active, inactive, and ~1,200 retired awaiting dismantling. Others vary slightly.
Military Stockpile: Warheads available for use estimated by FAS at ~4,380. SIPRI estimated ~4,489 (early 2024).
Deployed Strategic Warheads: On ICBMs, SLBMs, or at bomber bases. FAS/SIPRI estimated ~1,710 (early 2024). This exceeds the New START limit (1,550), which Russia suspended participation in (2023).
Stored Strategic Warheads: Estimated 1,112 in reserve.
Non-Strategic (Tactical) Warheads: FAS estimates ~1,558. Believed held in central storage, not deployed day-to-day. Uncertainty remains, with past US estimates between 1,000-2,000.
Despite cuts from the ~45,000 peak, Russia's arsenal is formidable and being heavily modernized, showing continued reliance on nuclear weapons.
Deployed Strategic Forces (Nuclear Triad):
ICBMs: Strategic Rocket Forces operate ~326 nuclear ICBM launchers (early 2024), silo and mobile. Includes:
~34 R-36M2 Voevoda (SS-18 Mod 6 'Satan'): Silo-based, heavy liquid-fueled, 10 MIRVs (likely fewer deployed under treaties), aging, slated for replacement by Sarmat.
~10 UR-100N UTTH (SS-19 Mod 4 'Stiletto'): Silo-based, liquid-fueled, modified for Avangard HGV.
~60 silo / ~18 mobile RT-2PM2 Topol-M (SS-27 Mod 1 'Sickle B'): Solid-fueled, single warhead.
~180 mobile / ~24 silo RS-24 Yars (SS-27 Mod 2): Mainstay, solid-fueled, MIRVed (~3-4 warheads each).
RS-28 Sarmat (SS-29 / SS-X-30 'Satan 2'): New heavy, liquid-fueled, silo ICBM for large MIRV (10+) or HGV payload. To replace SS-18. Announced combat duty late 2023, but likely not fully operational yet.
SLBMs: Sea-based force relies on SSBNs, likely 11-12 operational (early 2024). Includes:
~5 Project 667BDRM Delfin (Delta IV class): Each carries 16 R-29RMU/RMU2 Sineva/Liner (SS-N-23 Skiff) liquid-fueled, MIRVed SLBMs (~4 warheads each).
7 Project 955/955A Borei class: Newest SSBNs (early 2024). Each carries 16 RSM-56 Bulava (SS-N-32) solid-fueled, MIRVed SLBMs (~4-6 warheads each). More being built.
Strategic Bombers: Long-Range Aviation has ~58-60 nuclear-capable heavy bombers. Includes:
~43-45 Tu-95MS/MSM Bear-H: Turboprops, being modernized (MSM), carry Kh-55/555 and Kh-101/102 ALCMs.
~15-17 Tu-160M Blackjack: Supersonic, variable-sweep wing, undergoing modernization (M standard), new production resumed. Carry similar ALCMs.
Command and Control (C2): Designed for centralized control, survivability, retaining Soviet elements with modernization.
Decision Authority: President (Supreme Commander-in-Chief), consults Defence Minister and Chief of General Staff.
Nuclear Briefcase ("Cheget"): Portable terminal for each of the three key officials, connects to secure network for alerts/authorization. Believed 2 of 3 needed for launch order. Famously activated during 1995 Norwegian rocket false alarm.
Communications Network ("Kazbek"): Links Cheget, Kavkaz-7 network, Baksan terminals at command posts. Connects leadership, General Staff, nuclear forces. Uses multiple hardened fixed/mobile command centers, periodically upgraded.
Launch Execution: General Staff sends codes/orders to units (silos, mobile launchers, SSBNs, bombers) after authorization. General Staff can also launch directly from command centers.
Perimeter System ("Dead Hand"): Soviet fail-safe, likely partly operational. Guarantees retaliation if leadership/command destroyed. Probably involves human crews in deep bunkers (like Kosvinsky Kamen) pre-authorized in crisis to launch if comms lost and nukes confirmed hitting Russia.
Infrastructure: Hardened bunkers (Kosvinsky Kamen, Yamantau Mountain?), early warning radars (network being modernized), space-based warning satellites. Modernization focuses on survivability, reliability, real-time data. Potential launch-on-warning posture combined with possible warning system gaps raises stability concerns despite redundancies.
Estimated Current Russian Nuclear Forces (Early 2024 - based on FAS):
Total Inventory: ~5,580 (incl. ~1,200 retired).
Military Stockpile: ~4,380 (usable strategic & non-strategic).
Deployed Strategic Warheads: ~1,710 (on ICBMs, SLBMs, at bomber bases).
Stored Strategic Warheads: ~1,112 (central storage).
Non-Strategic Warheads: ~1,558 (central storage, high uncertainty).

6. Nuclear Arms Control Treaties
The US-Soviet/Russian nuclear relationship has been heavily influenced by treaties limiting strategic arsenals.
Overview of Key Treaties:
SALT I (1972): Included the Anti-Ballistic Missile (ABM) Treaty (restricted missile defenses) and an Interim Agreement freezing ICBM/SLBM launcher numbers for 5 years. Didn't limit warheads per missile (MIRVs) or bombers.
SALT II (1979): Aimed for equal limits (2,250 delivery vehicles), sub-limits on MIRVed systems. Never entered force (US Senate didn't ratify after Soviet invasion of Afghanistan), but generally observed for years.
INF Treaty (1987): Landmark deal eliminating all US/Soviet ground-launched missiles (500-5,500 km range). 2,692 missiles destroyed by 1991. US withdrew in 2019 citing Russian non-compliance (9M729 missile); Russia then terminated participation.
START I (1991): Entered force 1994, expired 2009. Mandated cuts to 1,600 delivery vehicles and 6,000 accountable warheads. Had extensive verification (inspections, data exchanges).
START II (1993): Aimed for deeper cuts (3,000-3,500 warheads) and banned MIRVed land-based ICBMs. Ratified but never entered force, as Russia tied it to the ABM Treaty, which the US left in 2002.
SORT (Moscow Treaty) (2002): Committed US/Russia to 1,700-2,200 operationally deployed strategic warheads by end of 2012. Lacked verification, didn't require destroying launchers/non-deployed warheads. Replaced by New START.
New START Treaty (2010): Only remaining US-Russia nuclear treaty. Entered force 2011, extended to Feb 4, 2026. Limits: 1,550 deployed strategic warheads, 700 deployed delivery vehicles (ICBMs, SLBMs, bombers), 800 total (deployed/non-deployed) launchers/bombers. Robust verification (data exchange, 18 inspections/year). Russia suspended participation in verification/data exchange Feb 2023, but stated adherence to numerical limits.
Impact on Arsenals: Treaties significantly shaped arsenal size/structure. Early SALT capped launchers but allowed MIRVs, leading to warhead increases in 70s/early 80s. INF eliminated a whole weapon class. START I forced first major, verifiable cuts from Cold War peaks. New START set lowest deployed warhead limits in decades, affecting force structure (e.g., maybe fewer warheads per MIRVed missile). The overall trend shows treaties helped reduce massive Cold War stockpiles. But New START's verification suspension hurts transparency and predictability, risking instability or a new arms race.
Key Arms Control Treaty Limits (USSR/Russia & USA):
SALT I Interim Agreement (1972): Expired. Limited ICBM+SLBM Launchers (US: 1,710; USSR: ~2,358). No warhead limits. Effective Oct 1972 - Oct 1977.
SALT II (1979): Never Entered Force. Aimed for 2,250 total delivery vehicles (ICBM/SLBM/Bombers) with MIRV sublimits. No warhead limits.
INF Treaty (1987): Terminated (2019). Prohibited all ground-launched missiles (500-5,500 km range). No warhead limits. Effective Jun 1988 - Aug 2019.
START I (1991): Expired. Limited to 6,000 accountable warheads and 1,600 delivery vehicles (ICBMs, SLBMs, Bombers). Effective Dec 1994 - Dec 2009.
START II (1993): Never Entered Force. Aimed for 3,000-3,500 warheads and banned MIRVed ICBMs.
SORT (Moscow Treaty) (2002): Replaced by New START. Limited to 1,700-2,200 operationally deployed warheads. No delivery vehicle limits. Effective Jun 2003 - Feb 2011.
New START Treaty (2010): In Force (Verification Suspended by Russia). Limits: 1,550 deployed warheads; 700 deployed delivery vehicles; 800 total deployed/non-deployed launchers/bombers. Effective Feb 2011 - Feb 2026.
7. Modernization and Future Systems
Russia is conducting a massive, long-term modernization of its entire nuclear triad, replacing Soviet-era systems. Defence Minister Shoigu claimed in Dec 2023 that modern systems made up 95% of the triad. This includes:
Ongoing Modernization:
ICBMs: Deploying RS-24 Yars (mobile/silo) to replace older Topol. Introducing Avangard HGV on modified SS-19s. Developing/deploying (though perhaps slowly) heavy RS-28 Sarmat to replace SS-18.
SLBMs: Phasing out older Delta III/Typhoon SSBNs. Building/deploying Borei-class SSBNs with Bulava solid-fueled SLBMs. Upgrading remaining Delta IV SSBNs and their Sineva/Liner liquid-fueled SLBMs.
Strategic Bombers: Modernizing Tu-95MS to Tu-95MSM standard (better avionics/weapons like Kh-101/102 ALCMs). Modernizing Tu-160 to Tu-160M standard and resuming new Tu-160M production.
This effort focuses on survivability (mobility, stealth, C2 hardening) and penetrating missile defenses (speed, maneuverability, MIRVs, HGVs, countermeasures).
New ("Next Generation") Systems: President Putin revealed several new strategic weapons in March 2018, often hypersonic or unconventional, seemingly to beat US missile defenses. Key systems are:
Avangard (Project 4202 / Yu-74): Hypersonic boost-glide vehicle (HGV) launched by ICBM. Maneuvers in atmosphere at claimed Mach 20+. Nuclear-capable (>2 MT?), range >6,000 km. First regiment (on modified SS-19s) operational Dec 2019. Planned for Sarmat eventually.
RS-28 Sarmat (SS-29 / SS-X-30 Satan 2): Though a replacement ICBM, its large payload allows for multiple Avangard HGVs or many MIRVs + countermeasures, key for beating defenses. Deployment seems delayed.
Poseidon (Status-6): Intercontinental-range, nuclear-powered, nuclear-armed unmanned underwater vehicle (UUV) / large torpedo. Deep-diving, targets coasts (radioactive contamination/tsunamis?). Carrier subs (like Belgorod) deploying. Russia claimed testing done end of 2023.
9M730 Burevestnik (SSC-X-9 Skyfall): Nuclear-powered, nuclear-armed cruise missile. Nuclear power gives near-unlimited range for complex evasion paths. Reportedly many test failures, but Russia claimed testing done late 2023. Operational status very uncertain.
Kh-47M2 Kinzhal ("Dagger"): Air-launched ballistic missile (ALBM), hypersonic (Mach 10?), maneuverable. Launched from MiG-31K/Tu-22M3, range ~1,500-2,000 km + aircraft range. Dual-capable (conventional/nuclear). Used conventionally in Ukraine war.
3M22 Tsirkon (SS-N-33): Ship/sub-launched hypersonic cruise missile (Mach 8-9?), range ~1,000 km. Dual-capable. Limited conventional use in Ukraine.
Systems like Poseidon and Burevestnik are major departures, exploring asymmetric capabilities and potentially new escalation risks. While their viability/rationale is debated, they show Russia's commitment to deterrence against perceived threats like missile defense. Despite announcements, deployment timelines (e.g., Sarmat) have slipped, suggesting challenges.
8. Russian Nuclear Doctrine
Russia's public statements on nuclear use have changed since Soviet times.
Evolution: The USSR was ambiguous, later adopted a "No First Use" pledge, which Russia dropped in 1993. Military Doctrines (2000, 2010, 2014) generally outlined nuclear use mainly for:
Responding to nuclear/WMD attack on Russia/allies.
Responding to large conventional aggression threatening the state's existence.
2020 "Basic Principles of State Policy on Nuclear Deterrence": In June 2020, Russia publicly released this dedicated document. It called nuclear weapons "exclusively a means of deterrence," used only as an "extreme and compelled measure". It listed four conditions for use:
Reliable data on ballistic missiles launched attacking Russia/allies.
Adversary uses nuclear/WMD against Russia/allies.
Adversary attacks critical Russian government/military sites, disrupting nuclear response.
Conventional aggression against Russia where the state's very existence is in jeopardy.
It also aimed to prevent escalation and end wars on acceptable terms.
2024 Updated "Basic Principles": Amid tensions (especially Ukraine war), Putin approved an update Nov 19, 2024. While framed as deterrence, it has significant changes:
Lowered Conventional Threshold: Replaces "very existence of the state" (Condition 4) with allowing use for conventional aggression posing a "critical threat to sovereignty and/or territorial integrity". "Critical threat" is more ambiguous, arguably lowering the threshold.
Expanded Launch Detection: Condition 1 now includes detecting a "massive launch (takeoff) of air and space attack weapons" (aircraft, cruise missiles, drones, hypersonics) crossing Russia's border.
Clarified Adversaries/Allies: Aggression by a non-nuclear state "involving or supported by any nuclear state" treated as a joint attack (voiding negative security assurances?). Explicitly extends nuclear umbrella to Belarus (Union State). Clarifies use possible for attacks on Russian forces/facilities outside Russia.
Deterrence Goals/Communication: Still aims for adversary understanding "inevitability of retribution" and preventing escalation/ending conflict acceptably. Notes President can inform others about readiness/decision to use nukes.
Comparison of Declared Conditions for Russian Nuclear Use (2020 vs. 2024):
Incoming Missile Attack:
2020: Ballistic missiles launched attacking Russia/allies.
2024: Adds massive launch/takeoff of air/space attack weapons (aircraft, cruise missiles, drones, hypersonics) crossing border.
WMD/Nuclear Use by Adversary:
2020: Against Russia/allies.
2024: Adds against Russian forces/facilities outside its territory.
Attack on Critical Infrastructure:
2020: Adversary attacks critical sites, undermining nuclear response.
2024: Same.
Conventional Aggression:
2020: Against Russia when state's existence is in jeopardy.
2024: Against Russia and/or Belarus that poses a "critical threat to their sovereignty and/or territorial integrity".
Aggression Involving Nuclear Allies:
2020: Implicit.
2024: Explicitly states aggression by non-nuclear state + nuclear state support = joint attack.
The 2024 update's timing/language strongly suggests an effort to boost deterrence/coercion, especially regarding the Ukraine war and Western support. The lower conventional threshold and broader scenarios seem aimed at influencing Western decisions. However, these public principles are for signaling; Russia likely has more detailed, classified operational plans, possibly with lower thresholds for non-strategic nuclear use in regional conflicts not fully shown publicly.
9. Conclusion
The Soviet and Russian nuclear story is complex, spanning over 80 years. Starting with early research, boosted by WWII needs and massive spying, the program quickly matched the US, testing its first atomic bomb in 1949 and a true H-bomb in 1955. The Cold War saw a huge buildup across ICBMs, SLBMs, and bombers, peaking at maybe 45,000 warheads by the mid-80s, including many non-strategic weapons.
After the USSR's fall, Russia inherited the arsenal and cut significantly under treaties like START I and New START. But nuclear weapons are still central to Russia's security. Today, Russia has the world's largest inventory (~5,580 total warheads, ~1,710 deployed strategic). A massive modernization is replacing old systems with advanced ones like Yars ICBMs, Borei subs/Bulava SLBMs, and upgraded bombers. Russia is also deploying novel systems like Avangard HGV (and maybe Poseidon UUV, Burevestnik missile) to beat defenses. The C2 system keeps Soviet features (Cheget, Perimeter) while modernizing. The public nuclear doctrine, updated 2024, lowered the threshold for use in conventional attacks ("critical threat to sovereignty/territorial integrity") and expanded scenarios involving allies and advanced weapons, seemingly to strengthen deterrence amid tensions.
New START's verification suspension and 2026 expiration, plus modernization and doctrine shifts, raise fears of renewed, unconstrained nuclear competition and miscalculation risks. Russia's continued heavy investment in its nuclear forces shows how vital these weapons remain to its strategy today.
