Russia Nuclear Forces and Military Power Profile

Russia possesses the world's largest nuclear arsenal and ranks as the second most powerful military force globally. As one of the five recognized nuclear-weapon states under the Non-Proliferation Treaty (NPT) and a permanent member of the UN Security Council, Russia's nuclear weapons program is central to its national security doctrine and shapes global nuclear risk calculations.

Nuclear Arsenal

Russia maintains the largest nuclear stockpile of any nation. Its deployed strategic warheads are spread across a nuclear triad of land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers.

Delivery Systems

Land-based ICBMs: Russia operates approximately 326 ICBMs across several types, including the SS-18 Satan, SS-27 Mod 2 (Yars), and the RS-28 Sarmat (Satan II) — a heavy ICBM capable of carrying up to 10 MIRVed warheads with a range exceeding 18,000 km.

Submarine-launched ballistic missiles (SLBMs): Russia's nuclear submarine fleet includes Borei-class submarines armed with RSM-56 Bulava SLBMs. Each submarine carries 16 missiles with up to 6 warheads each.

Strategic bombers: The Russian Aerospace Forces operate Tu-160 Blackjack and Tu-95MS Bear-H bombers capable of delivering nuclear-armed cruise missiles, including the Kh-102 air-launched cruise missile.

Non-strategic (tactical) nuclear weapons: Russia maintains an estimated 1,558 tactical nuclear warheads for use with short-range missiles, torpedoes, depth charges, and artillery — the largest tactical nuclear arsenal in the world.

Military Overview

Russia's military is the second-largest in the world by conventional strength rating, with extensive ground forces, a modernizing navy, and advanced air defense systems including the S-400 and S-500.

Role in Current Nuclear Risk

Russia's nuclear posture directly affects the Doomsday Clock. Key risk factors include:

• Nuclear doctrine: Russia's 2020 nuclear doctrine permits first use of nuclear weapons in response to conventional attacks threatening state existence. In 2024, Russia lowered this threshold further.
• Ukraine conflict: The ongoing war in Ukraine has seen repeated nuclear rhetoric from Russian officials and changes to deployment postures.
• Arms control collapse: The suspension of New START inspections and the withdrawal from the Comprehensive Test Ban Treaty (CTBT) ratification have weakened guardrails.
• Iran crisis: Russia's diplomatic positioning on the Iran nuclear situation and its relationships with regional actors add complexity to the current escalation.

Position on the Iran Crisis

Russia's response to Operation Epic Fury reflects a calculated balancing act between opposing US military action and avoiding direct confrontation with Washington while it remains engaged in Ukraine.

Diplomatic positioning: Russia condemned the US-Israeli strikes as "an act of aggression against a sovereign state" and called for an emergency UN Security Council session. However, when the session convened, Russia abstained rather than vetoing — a notable choice that suggests Moscow wants to criticize the operation without committing to action that would further strain its relationship with the West.

Energy leverage: Russia is a direct beneficiary of the Strait of Hormuz blockade. With 20% of global oil supply removed from the market, Russian crude commands higher prices and displaces Gulf supply for Asian buyers. Brent crude above $125/barrel generates windfall revenue for Moscow at a time when war expenditures in Ukraine are straining the Russian budget. Russia has no incentive to help reopen the strait quickly.

Arms and military ties: Russia previously sold Iran the S-300 air defense system and has conducted joint naval exercises with Iran in the Indian Ocean. The effectiveness (or failure) of Russian-supplied air defenses against American stealth aircraft and precision munitions is being closely studied by military analysts worldwide — with implications for Russian arms export credibility and NATO defense planning.

Ukraine calculus: The Iran crisis diverts American military assets and political attention from Ukraine. Every B-2 bomber sortie over Iran, every Patriot battery deployed to the Gulf, and every hour of White House crisis management is a resource not directed at supporting Kyiv. Some analysts assess that Russia may view a prolonged US-Iran conflict as strategically advantageous for its own objectives in Eastern Europe.

Nuclear precedent: The destruction of a NPT signatory state's nuclear facilities by military force creates a precedent that Russia views with ambivalence. Moscow benefits from the NPT framework as a recognized nuclear-weapon state, and the erosion of nonproliferation norms could encourage nuclear proliferation among states Russia considers adversaries. However, Russia has also used concerns about Ukrainian nuclear capabilities as justification for its own military operations.
