It was detonated at dawn on March 1, 1954. Scientists miscalculated: the 15 Mt of TNT nuclear explosion far exceeded the expected yield of 4–8 Mt of TNT (6 predicted). [5]
- Castle Bravo - WikipediaCastle 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 resulting radioactive fallout might have been catastrophic, not just for the Soviet Union but for its neighbors. And it would have, if the Tsar Bomba’s original concept—yielding an almost inconceivable 100 megatons—had been pursued.
- Castle BRAVO at 70: The Worst Nuclear Test in U.S. HistoryThe Bravo detonation in the Castle test series had an explosive yield of 15 megatons — 1,000 times that of the weapon that destroyed Hiroshima and nearly three times the six megatons that its planners estimated.
- Castle Bravo - Nuclear MuseumOn March 1, 1954, the United States carried out its largest nuclear detonation, “Castle Bravo,” at Bikini Atoll in the Marshall Islands. The Bravo explosion was more than two and a half times greater than expected and caused far higher levels of fallout and damage than scientists had predicted.
