Fact Box:
Current State of Nuclear Warheads (As of 2024)
- Nuclear-Weapon States (NWS) under the Nuclear Nonproliferation Treaty (NPT): The five officially recognized nuclear-weapon states under the NPT are: United States, Russia, China, France, United Kingdom.
- Total Nuclear Warheads Worldwide: Approximately 12,100 nuclear warheads across all states with nuclear capabilities.
- The United States and Russia possess the largest share of global nuclear stockpiles, with ongoing modernization of their nuclear forces.
- Other countries like China, India, and Pakistan have smaller stockpiles but are actively enhancing their nuclear capabilities, including missile delivery systems.
- North Korea and Iran remain significant proliferation concerns due to their ongoing nuclear development activities and potential for expanding their arsenals.
Estimates of Nuclear Stockpiles:
- Russia
- Strategic warheads: 1,549 warheads deployed on 540 delivery systems (ICBMs, SLBMs, and heavy bombers) as of September 2022 (New START data).
- Non-strategic warheads: Estimated 1,000–2,000 warheads (not limited by the New START treaty).
- Total stockpile: Approximately 4,380 nuclear warheads as of March 2024 (including deployed and retired warheads awaiting dismantlement).
- United States
- Strategic warheads: 1,419 deployed on 662 delivery systems (ICBMs, SLBMs, and heavy bombers) as of March 2023 (New START data).
- B-61 gravity bombs: Estimated 100 forward-deployed bombs at NATO bases across Europe.
- Total stockpile: 3,748 active and inactive warheads as of September 2023 (including 2,000 retired warheads awaiting dismantlement).
- Total warheads (FAS estimate): Approximately 5,044 warheads as of May 2024 (including retired warheads).
- China
- Strategic warheads: 310 warheads deployed on 206 launchers (ICBMs and SLBMs).
- Total warheads: Estimated 440 warheads as of 2023 (with projections reaching up to 1,000 by 2030).
- France
- Total stockpile: Approximately 290 operational warheads, deployed on 98 delivery systems, including submarine-launched ballistic missiles (SLBMs) and air-launched cruise missiles.
- Modernization: France continues to modernize its nuclear forces but does not plan to increase the size of its stockpile.
- United Kingdom
- Total stockpile: Approximately 225 warheads, with 120 operational warheads on 48 SLBMs and 105 in storage.
- Sea-based deterrent: The UK exclusively relies on sea-based nuclear deterrence with its Vanguard-class Trident submarines.
Non-NPT Nuclear Weapons Possessors
These states have developed nuclear weapons outside the NPT framework:
- India
- Total stockpile: Estimated to have up to 172 nuclear warheads.
- India tested its first nuclear weapon in 1974, sparking a nuclear arms race with Pakistan.
- Pakistan
- Total stockpile: Estimated to have approximately 170 nuclear warheads.
- Pakistan’s nuclear program was a direct response to India’s nuclear weapons development.
- Israel
- Total stockpile: Estimated to have around 90 nuclear warheads, with fissile material for about 200.
- Israel has never officially confirmed or denied possessing nuclear weapons and follows a policy of ambiguity regarding its nuclear arsenal.
