Countries with the Most Nuclear Warheads 2025
Countries possessing nuclear weapons, ranked by estimated total stockpile size in 2025. Russia and the United States together account for approximately 90% of all nuclear warheads on Earth, each holding over 5,000 warheads in various states of deployment, storage, and dismantlement.
Analysis
Russia heads the table on 5,580, ahead of United States (5,044) and China (500) in Estimated Nuclear Warheads in 2025. 5,490 separates the highest figure (5,580) from the lowest (90). First and second are separated by 536, so the leader sits inside the field rather than apart from it. Only 2 of the 8 reach even half the leader's figure (2,790 or more).
