Castle Bravo is the sixth largest nuclear explosion in history, exceeded by the Soviet tests of Tsar Bomba at approximately 50 Mt, Test 219 at 24.2 Mt, and three other (Test 147, Test 173 and Test 174) ≈20 Mt Soviet tests in 1962 at Novaya Zemlya.
The Castle Bravo test produced the highest fallout levels in history. [64] The detonation produced an explosion approximately 2.5 times the predicted 6.0 megatons, equal to 15 Mt of TNT. [ 6 ] The residents of Rongelap and Utirik atolls were exposed to high levels of radiation, the heaviest of which was in the form of pulverized surface coral ...
Operation Castle was an unqualified success for the implementation of dry fuel devices. The Bravo design was quickly weaponized and is suspected to be the progenitor of the Mk-21 gravity bomb. The Mk-21 design project began on 26 March 1954 (just three weeks after Bravo), with production of 275 weapons beginning in late 1955.
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 ...
Half Life: A Parable for the Nuclear Age is a 1985 Australian documentary film directed by Dennis O'Rourke, concerning the American Castle Bravo nuclear testing at the Marshall Islands in 1954. The film features interviews with residents of the nearby Rongelap and Utirik Atolls who were affected by nuclear fallout from the tests.
Castle Bravo demonstrated the dangers of nuclear weapons. With a much higher yield than expected, it destroyed the island and produced greater fallout than anticipated. The United States detonated 23 nuclear devices between 1946 and 1958 at seven test sites on the reef, inside the atoll, in the air, and underwater. [22]

Six very large nuclear tests were conducted at the Bikini Atoll and the Enewetak Atoll as part of Operation Castle in 1954. The most notable was Castle Bravo, which was the first deployable (dry fuel) hydrogen bomb developed by the United States. Its yield, at 15 Mt, was over twice as powerful as was predicted, and remains the largest weapon ...
