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 Soviet Union also tested the most powerful explosive ever detonated by humans, ("Tsar Bomba"), with a theoretical yield of 100 megatons, reduced to 50 when detonated. After its dissolution in 1991, the Soviet weapons entered officially into the possession of its successor state , the Russian Federation. [ 56 ]
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 ...
Novaya Zemlya was one of the two major nuclear test sites managed by the USSR along with the Semipalatinsk Test Site; it was used for air drops and underground testing of the largest of Soviet nuclear bombs, in particular the October 30, 1961, air burst explosion of Tsar Bomba, the largest, most powerful nuclear weapon ever detonated.
Kennedy specifically limited such testing to underground and laboratory tests, but under mounting pressure as Soviet tests continued—during the time period of the Soviet Tsar Bomba 50 Mt+ test detonation on 30 October over Novaya Zemlya—Kennedy announced and dedicated funds to a renewed atmospheric testing program in November 1961.

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.
