The United States was the first nation to develop the hydrogen bomb, testing an experimental prototype in 1952 ("Ivy Mike") and a deployable weapon in 1954 ("Castle Bravo"). Throughout the Cold War it continued to modernize and enlarge its nuclear arsenal, but from 1992 on has been involved primarily in a program of stockpile stewardship.
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 device fell through the closed bomb bay doors of the bomber, which was approaching Kirtland at an altitude of 520 metres (1,700 ft). The device's conventional explosives destroyed it on impact, leaving a crater 7.6 metres (25 ft) in diameter and 3.7 metres (12 ft) deep. [ 5 ]

North Korea's claim of a successful H-bomb test marks a big step in its long-stated goal of developing a nuclear missile that puts the U.S. within range. Possible two-stage hydrogen bomb seen ...
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 ...
