This map layer with a timeline shows the time sequence of the number of nuclear weapons, in five categories, for the years 1946 to 2018.
Since 1945, more than 128,000 nuclear weapons have been produced, 55 per cent of which in the United States, 48 of which in Russia. Since 1986, the number of operational nuclear weapons has decreased, as the United States and Russia have bound themselves to cut down the number of active nuclear weapons. But nuclear weapons are withdrawn from service more quickly than disposed of so that an inactive holding of nuclear weapons exists. Beyond this, nuclear powers continue to modernize their stockpiles or even re-arm themselves.
It is important to observe that only the military stock has been provided for the United States and Russia!
