Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%. [3] [4] According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield Minuteman I missile warhead.

Ivy Mike was the codename given to the first full-scale [note 1] test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion. [ 1 ] [ 2 ] [ 3 ] Ivy Mike was detonated on November 1, 1952, by the United States on the island of Elugelab in Enewetak Atoll , in the now independent island nation ...
The first Ivy shot, codenamed Mike, was the first successful full-scale test of a multi-megaton thermonuclear weapon ("hydrogen bomb") using the Teller-Ulam design.Unlike later thermonuclear weapons, Mike used deuterium as its fusion fuel, maintained as a liquid by an expensive and cumbersome cryogenic system.
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961. Russia releases secret footage of 1961 'Tsar Bomba' hydrogen ...

North Korea said it had successfully conducted a test of a miniaturized hydrogen nuclear device on Wednesday morning.
The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the Nevada Test Site. Operation originally named "Operation Faust". Greenhouse: 1951 4: 4: 4: 46 to 225 398: George shot was physics experiment relating to the hydrogen bomb; Item shot was first boosted ...
RDS-37 was the Soviet Union's first two-stage hydrogen bomb, first tested on 22 November 1955. The weapon had a nominal yield of approximately 3 megatons . It was scaled down to 1.6 megatons for the live test.
