Castle Bravo was the code name given to the first United States test of a dry fuel thermonuclear hydrogen bomb, detonated on March 1, 1954, at Bikini Atoll, Marshall Islands, as the first test of Operation Castle. Castle Bravo was the most powerful nuclear device ever detonated by the United States (and just under one-third the energy of the most powerful ever detonated), with a yield of 15 megatons of TNT. That yield, far exceeding the expected yield of 4 to 8 megatons (6Mt predicted), combined with other factors, led to the most significant accidental radiological contamination ever caused by the United States.

abstract
  • Castle Bravo was the code name given to the first United States test of a dry fuel thermonuclear hydrogen bomb, detonated on March 1, 1954, at Bikini Atoll, Marshall Islands, as the first test of Operation Castle. Castle Bravo was the most powerful nuclear device ever detonated by the United States (and just under one-third the energy of the most powerful ever detonated), with a yield of 15 megatons of TNT. That yield, far exceeding the expected yield of 4 to 8 megatons (6Mt predicted), combined with other factors, led to the most significant accidental radiological contamination ever caused by the United States. Fallout from the detonation—intended to be a secret test—fell on residents of Rongelap and Utrik Atolls and spread around the world. The islanders were not evacuated until three days later and suffered radiation sickness. They were returned to the islands three years later but were removed again when their island was found to be unsafe. The crew of the Japanese fishing vessel Daigo Fukuryū Maru ("Lucky Dragon No. 5"), was also contaminated by fallout, killing one crew member. The blast created an international reaction about atmospheric thermonuclear testing.
