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.

The USSR and United States nuclear weapon stockpiles throughout the Cold War until 2015, with a precipitous drop in total numbers following the end of the Cold War in 1991. Nuclear disarmament refers to both the act of reducing or eliminating nuclear weapons and to the end state of a nuclear-free world, in which nuclear weapons are eliminated.
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.
France tested its first hydrogen bomb in 1968 ("Opération Canopus"). After the Cold War, France has disarmed 175 warheads with the reduction and modernization of its arsenal that has now evolved to a dual system based on submarine-launched ballistic missiles (SLBMs) and medium-range air-to-surface missiles (Rafale fighter-bombers).
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 ...
During the Cold War, the term "weapons of mass destruction" was primarily a reference to nuclear weapons. At the time, in the West the euphemism "strategic weapons" was used to refer to the American nuclear arsenal. However, there is no precise definition of the "strategic" category, neither considering range nor yield of the nuclear weapon. [16]
In a New Mexico PBS series, "A Commitment to Peace," it looks closely at how the following dramatic Cold War years were complicated by personalities, ideologies, old fears and new visions. Michael ...
