A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs , a more compact size, a lower mass, or a combination of these benefits.
The hydrogen bomb primarily has 2 units: a nuclear bomb, which was the primary unit, and a secondary energy unit. The first stage of the hydrogen bomb resembled the layer-cake design, except the main difference is that the initiation is carried out by a nuclear device, rather than a conventional explosive.

After Truman ordered the crash program to develop the hydrogen bomb in January 1950, the Boston Daily Globe published a cutaway description of a hypothetical hydrogen bomb with the caption Artist's conception of how H-bomb might work using atomic bomb as a mere "trigger" to generate enough heat to set up the H-bomb's "thermonuclear fusion" process.
The Atomic Cafe is a 1982 American documentary film directed by Kevin Rafferty, Jayne Loader and Pierce Rafferty. [2] [3] [4] It is a compilation of clips from newsreels, military training films, and other footage produced in the United States early in the Cold War on the subject of nuclear warfare.
The first successful hydrogen bomb test occurred on November 8, 1957, which had a yield of 1.8 megatons. [26] An amendment to the Atomic Energy Act in 1958 allowed nuclear cooperation once again, and British-U.S. nuclear programs resumed. During the Cold War, British nuclear deterrence came from submarines and nuclear-armed aircraft.
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961, 4,000 meters over the remote Novaya Zemlya archipelago above the ...
The bomb was hailed as a hydrogen bomb, and the truth that it was actually a large fission bomb was kept secret by the British government until the end of the Cold War. [135] [136] An Operational Requirement (OR1142) had been issued in 1955 for a thermonuclear warhead for a medium-range ballistic missile, which became Blue Streak. This was ...
The Cold War (1948–1953) is the ... Truman ordered the development of a hydrogen bomb. In early 1950, the U.S. took its first efforts to oppose communist forces in ...
