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).

[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 ] Prior to the main five-megaton test in 1971, a 1 Mt (4.2 PJ) test took place on the island on October 2, 1969, for calibration purposes, and to ensure the subsequent Cannikin test could ...
Edward Teller, perhaps the most ardent supporter of the development of the hydrogen bomb, was in Berkeley, California, at the time of the shot. [32] He was able to receive first notice that the test was successful by observing a seismometer, which picked up the shock wave that traveled through the earth from the Pacific Proving Grounds.
