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 ...
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
The largest nuclear weapon ever tested was the Tsar Bomba of the Soviet Union at Novaya Zemlya on October 30, 1961, with the largest yield ever seen, an estimated 50–58 megatons.
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.
Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency. It was launched from Johnston Atoll on July 9, 1962, and was the largest nuclear test conducted in outer space, and one of five conducted by the US in space.
The experiment, part of the Operation Grommet nuclear test series, tested the unique W71 warhead design for the LIM-49 Spartan anti-ballistic missile. [2] [3] With an explosive yield of almost 5 megatons of TNT (21 PJ), the test was the largest underground explosion ever detonated by the United States. [4]
