Below is a graph showing the evolution of nuclear warhead stockpiles from 1945 to September 2023. The stockpile, which exceeded 5,000 in the 1950s, increased to 25,540 at the time of the Cuban Missile Crisis in 1962. In 1967, it recorded a record high of 31,255 warheads. Since then, except for around 1974, it has basically been on a downward trend, and in 1989, when the Berlin Wall collapsed and the Cold War ended, it was 22,217 warheads. In September 2023, the latest state released, it has decreased to 3,748 warheads.

The 'nuclear warhead stockpile' shown in this data includes both active and inactive warheads.
'Active' refers to those in an immediately operational configuration, including strategic weapons, non-strategic weapons, warheads ready for deployment, and spares, with tritium bottles and limited-life components installed. 'Inactive' refers to those in storage, with tritium bottles and other components removed.
The United States' non-strategic nuclear weapons have been reduced by more than 90% since September 30, 1991.
