Stockpile of nuclear weapons available for use is increasing

The nine nuclear-armed states had a combined arsenal of 12,705 nuclear warheads at the beginning of 2022. Of these, an estimated 9,440 warheads – with a collective yield equivalent to approximately 138,000 Hiroshima-bombs – constituted usable stockpiles, available for use by the nuclear armed states on their missiles, aircraft, submarines and ships. The number of nuclear warheads in usable stockpiles is now on the rise, warns the watchdog Nuclear Weapons Ban Monitor.
