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).
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.
The first target of nuclear weapons, the Mark I atomic bomb. The target was the Aioi Bridge across the Ōta River ; it exploded several hundred yards off. Hiroshima was a city of 250,000, suffering 70,000 or so deaths immediately and up to 126,000 by the end of the year.
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 ...
The Tsar Bomba was detonated in October 1961, in the vicinity of Matochkin Strait, over the Novaya Zemlya archipelago. [2]It is also the site where, from 1963 to 1990, about 39 underground nuclear tests took place in a vast array of tunnels and shafts under Mount Lazarev and other massifs.
The village was located 55 kilometres (34 miles) from ground zero within the Sukhoy Nos test range. Tsar Bomba was the most powerful nuclear weapon detonated and was the most powerful anthropogenic explosion in human history. It had a yield of 50 megatons of TNT, scaled down from its maximum 100 megaton design yield. [8]
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 energy released from the explosion has been estimated to be equal to about 200 megatonnes of TNT (840 petajoules), [11] roughly four times as powerful as the Tsar Bomba, the most powerful thermonuclear weapon ever detonated. This makes it one of the most powerful explosions in recorded history.
