The Castle Bravo device was housed in a cylinder that weighed 23,500 pounds (10,700 kg) and measured 179.5 inches (456 cm) in length and 53.9 inches (137 cm) in diameter. [3] The primary device was a COBRA deuterium-tritium gas-boosted atomic bomb made by Los Alamos Scientific Laboratory, a very compact MK 7 device.
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 second series of tests in 1954 was codenamed Operation Castle. The first detonation was Castle Bravo, which tested a new design utilizing a dry-fuel thermonuclear bomb. 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). [6]
RDS-37 videos have the detonation in the center, and Tsar Bomba videos have the detonation to the right (except for the mushroom-cloud video, which is in the center) [citation needed]. In addition, the RDS-37 test occurred in the Semipalatinsk test area, and some of the video looks across the roofs of the secret city of Kurchatov , aka ...

As the head of the Los Alamos Laboratory's J (Test) Division, [5] he was the scientific director or deputy director of most of the nuclear tests from 1948 through the 1950s, including the Desert Rock exercises which exposed military personnel to radiation, and the Castle Bravo test that irradiated many native islanders and test personnel.
The Mark 21 nuclear bomb was a United States thermonuclear gravity bomb first produced in 1955. It was based on the TX 21 "Shrimp" prototype that had been detonated during the Castle Bravo test in March 1954.
Setsuko Thurlow's activism began after March 1, 1954, after the explosion of the hydrogen bomb of the code name "Castle Bravo" in the Bikini Atoll in the Marshall Islands which had nuclear fallout until Japan. [20] [21] This American weapon was approximately one thousand times more powerful than the one she had been victim of less than 10 years ...
