The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest human-made explosion in history. [64] For comparison, the largest weapon ever produced by the US, the now-decommissioned B41 , had a predicted maximum yield of 25 Mt (100 PJ).
The Castle Bravo shot of 1 March 1954, at Bikini Atoll, was the first test of a deployable (solid fuel) thermonuclear weapon, and also (accidentally) [citation needed] the largest weapon ever tested by the United States (15 megatons). It was also the single largest U.S. radiological accident in connection with nuclear testing.
Test with "energy budget". Competition between UCRL and LASL over budget allocation was high. Project 57: 1957 1: 1: 1: 0 0: The first safety test, asking whether an improperly ignited bomb (as in a plane crash) would cause a nuclear blast. Plumbbob: 1957 29: 29: 25: 0 to 74 345: Included the largest atmospheric test in CONUS. Project 58+58A ...
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 ...

Ivy King was the largest pure-fission nuclear bomb ever tested by the United States. [1] The bomb was tested during the Truman administration as part of Operation Ivy.This series of tests involved the development of very powerful nuclear weapons in response to the nuclear weapons program of the Soviet Union.
The Mark 24 nuclear bomb was an American thermonuclear bomb design, based on the third American thermonuclear bomb test, Castle Yankee.The Mark 24 bomb was tied as the largest weight and size nuclear bomb ever deployed by the United States, with the same size and weight as the Mark 17 nuclear bomb which used a very similar design concept but unenriched lithium.
Afterwards, the Comprehensive Test Ban Treaty was signed and ratified by the major nuclear weapons powers, and the number of worldwide nuclear tests decreased rapidly. [24] India and Pakistan conducted nuclear tests in 1998, but afterwards only North Korea conducted nuclear tests-- in 2006, 2009, 2013, twice in 2016, and in 2017 .
