Moreover, total deployed US & "Russian" strategic weapons increased steadily from the 1980s until the Cold War ended. [18] The United States nuclear stockpile increased rapidly from 1945, peaked in 1966, and declined after that. [1] By 2012, the United States had several times fewer nuclear weapons than it had in 1966. [19]
The Castle Bravo fallout plume spread dangerous levels of radioactive material over an area over 100 miles (160 km) long, including inhabited islands, in the largest single U.S. nuclear accident. The United States nuclear program since its inception has experienced accidents of varying forms, ranging from single-casualty research experiments ...
Note that raw stockpile totals do not necessarily tell you much about nuclear capabilities; delivery mechanisms and types of weapons can make a big difference (many of the weapons added to the stockpile during the "surge" periods were tactical, not strategic, for example)
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).
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 ...
Scientists charged with ensuring the aging U.S. stockpile of nuclear weapons are good to go — if needed — say they'll start shipping key components to Nevada's desert next year to prepare for ...
The Enduring Stockpile is the United States' arsenal of nuclear weapons following the end of the Cold War. During the Cold War the United States produced over 70,000 nuclear weapons. By its end, the U.S. stockpile was about 23,000 weapons of 26 different types.
In the event of a larger war between the U.S. and Russia, which together are believed to hold more than 90% of the world’s nuclear stockpile, an estimated 5 billion out of 6.7 billion people ...
