Despite significant progress in reducing nuclear weapon arsenals since the Cold War, the world’s combined inventory of warheads remains at an uncomfortably high level.
Towards the late 1980s, the world reached its peak of stockpiled warheads, numbering over 64,000. In modern times, nine countries—the U.S., Russia, France, China, the UK, Pakistan, India, Israel, and North Korea—are estimated to possess roughly 12,700 nuclear warheads.
The animated chart above by creator James Eagle shows the military stockpile of nuclear warheads that each country has possessed since 1945.
The signing of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) brought about a rapid disarmament of nuclear warheads. Though not immediately successful in stopping nuclear proliferation, it eventually led to countries retiring most of their nuclear arsenals.
As of 2022, about 12,700 nuclear warheads are still estimated to be in use, of which more than 9,400 are in military stockpiles for use by missiles, aircraft, ships and submarines.
