France became a nuclear power in 1960, and French nuclear stockpiles peaked at just over 500 nuclear weapons in 1992. [1] China developed its first nuclear weapon in 1964; its nuclear stockpile increased until the early 1980s, when it stabilized at between 200 and 260. [1] India became a nuclear power in 1974, while Pakistan developed its first ...
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Weapons variable yield and weight have been plotted at their highest yield and weight. Also indicated on the graph are a few characteristics of the weapons (Little Boy and Fat Man, the early H-bombs, small tactical weapons, and weapons in the enduring stockpile separated by missile warheads and air-dropped bombs).

Trinity test on 16 July 1945, was the world's first test of a nuclear weapon (yield of around 20 kt). Operation Crossroads series in July 1946, was the first postwar test series and one of the largest military operations in U.S. history.

Despite having an almost-exact explosive-yield and assembly method as Little Boy, the first nuclear weapon ever deployed in combat, the W9 nuclear artillery-shell test-fired during Operation Upshot-Knothole series of tests was far smaller and lighter than its predecessors; a result of the evolving efficiencies of new nuclear-weapon designs.
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
