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).
Date time Local time zone ... Detonation over NZ Area C, Sukhoy Nos, ... 130 Tsar Bomba (Joe 111) 30 October 1961 08:33:27.8
RDS-27, 250 kiloton bomb, a 'boosted' fission bomb tested 6 November 1955. RDS-37, 3 megaton bomb, the first Soviet two-stage hydrogen bomb, tested 22 November 1955; RDS-220 Tsar Bomba an extremely large three stage bomb, initially designed as a 100-megaton-bomb, but was scaled down to 50 megatons for testing. Intercontinental Ballistic Missiles
The Tsar Bomba far surpassed the largest explosion the United States has ever conducted - a 15-megaton "Castle Bravo" hydrogen bomb detonated on Bikini Atoll in 1954. (Reporting by Maria Vasilyeva ...
A tacit moratorium on testing was in effect from 1958 to 1961 and ended with a series of Soviet tests in late 1961, including the Tsar Bomba, the largest nuclear weapon ever tested. The United States responded in 1962 with Operation Dominic, involving dozens of tests, including the explosion of a missile launched from a submarine.
RDS-37, November 22, 1955: first Soviet multi-megaton, true hydrogen bomb test using Andrei Sakharov's third idea, essentially a re-invention of the Teller-Ulam. Tsar Bomba, October 30, 1961: largest nuclear weapon ever detonated, with a design yield of 100 Mt, de-rated to 50 Mt for the test drop.
The thermonuclear Tsar Bomba was the most powerful bomb ever detonated. [6] As thermonuclear weapons represent the most efficient design for weapon energy yield in weapons with yields above 50 kilotons of TNT (210 TJ), virtually all the nuclear weapons of this size deployed by the five nuclear-weapon states under the Non-Proliferation Treaty ...
1968 – January 28 – An aircraft accident occurs when an American B-52 bomber armed with a Mark 28 nuclear bomb bound for Thule Air Base, Greenland, has an in-flight fire and is forced to make a crash landing in North Star Bay, resulting in the detonation of the bomb's conventional explosives and the release of radioactive contamination over ...
