Castle Bravo was the first test by the United States of a practical deliverable fusion bomb, even though the TX-21 as proof-tested in the Bravo event was not weaponized. The successful test rendered obsolete the cryogenic design used by Ivy Mike and its weaponized derivative, the JUGHEAD , which was slated to be tested as the initial Castle ...
Castle Bravo remains, to this day, the largest detonation ever carried out anywhere by the United States and the fifth largest H-bomb detonation in the world. Because Castle Bravo greatly exceeded its expected yield, JTF-7 was caught unprepared. Much of the permanent infrastructure on Bikini Atoll was heavily damaged.
The first test of that series was Castle Bravo, a new design utilizing a dry fuel thermonuclear bomb. It was detonated at dawn on March 1, 1954. It was detonated at dawn on March 1, 1954. The explosion yielded 15 Mt of TNT, far exceeding the expected yield of 4 to 8 Mt of TNT (6 predicted), [ 6 ] and was about 1,000 times more powerful than ...
A simplified and lightened bomb version (the EC-16) was prepared and scheduled to be tested in operation Castle Yankee, as a backup in case the non-cryogenic "Shrimp" fusion device (tested in Castle Bravo) failed to work; that test was canceled when the Bravo device was tested successfully, making the cryogenic designs obsolete.

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 ...
March 1, 1954: United States detonates 15-megaton hydrogen bomb (Castle Bravo test) allegedly unaware that fallout will reach Rongelap. [8] March 3, 1954: US evacuates Rongelap inhabitants to Kwajalein Atoll. Islanders have vomiting, diarrhea, skin burns, and some later experience hair loss. They were suffering from acute radiation syndrome.
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 ...
In 1954 the Castle Bravo fallout plume spread dangerous levels of radiation over an area over 100 miles (160 km) long, including inhabited islands. Atomic and nuclear tests can involve many hazards. Some of these were illustrated in the US Castle Bravo test in 1954. The weapon design tested was a new form of hydrogen bomb, and the scientists ...
