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 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.
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 ]
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.
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 TX-21 was a scaled-down version of the Runt device (M-17 hydrogen bomb). Smaller in size and weight to the Mk-17, the Mk-21 was considered as a potential missile warhead. Far more powerful than the TX-13, which was a high-yield atomic bomb developed from the Mk-6 bomb, the XW21 was to replace the XW13 in the weapons pod of the B-58 bomber ...
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 ...
