Nuclear

Who has how many warheads, and what the most-cited symbolic clock says. These are published estimates, not live data. Tension pairs between nuclear states arrive in Phase 4.

Doomsday Clock

85 s

to midnight · set 2026-01-27

A symbolic setting by the Bulletin's Science and Security Board, not a measurement or a probability.

Military stockpile

9,745

4,012 deployed · 5,733 in storage

Warheads that could be used: the number that matters most.

Total inventory

12,187

incl. 2,442 retired, awaiting dismantling

Falls as old warheads are dismantled even while usable stockpiles grow.

All estimates are approximate. SIPRI revises its figures every year as new information appears.
New START expired in February 2026 with no replacement treaty; Russia and the US no longer publish aggregate strategic force data under it.
North Korea: fissile material for up to 90 warheads may exist, but SIPRI estimates about 60 assembled.
France's total-inventory jump (290 to 370) is a data fix: retired warheads were previously unknown, not a build-up.
Russia's military-stockpile increase is largely a reassessment of non-strategic (tactical) warheads.

deployed:: Warheads on missiles or at bases with operational forces.
stored:: Warheads in storage or reserve that would need some preparation before deployment.
military Stockpile:: Deployed plus centrally stored warheads that could potentially be deployed.
retired:: Warheads removed from the military stockpile, not yet dismantled.
total Inventory:: Military stockpile plus retired warheads.

Nuclear power plants

Civil power reactors are not weapons. They are shown because a war, quake or flood near a plant is a risk of its own; Phase 5 will link such events to nearby plants. Switch on Nuclear on the map to see all 195.
