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 nuclear shaped charge concept was also studied extensively in the 1980s as part of Project Prometheus, along with bomb-pumped lasers. Using a combination of explosive wave-shaping and "gun-barrel" design, up to 5% of a small nuclear bomb could reportedly be converted into kinetic energy driving a beam of particles with a beam angle of 0.001 ...
This crash project was developed partially with information obtained via the atomic spies at the United States' Manhattan Project during and after World War II. The Soviet Union was the second nation to have developed and tested a nuclear weapon. It tested its first megaton-range hydrogen bomb ("RDS-37") in 1955.
Trinity, part of Project Manhattan, was the first ever nuclear explosion. The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race . The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
[8] [12] Schreiber became the associate leader of W Division in 1947, and then the head of the division in 1951. During this time, W Division worked on the development of the hydrogen bomb. He was once again in charge of the pit crew for the Ivy Mike nuclear test on Enewetak Atoll in the Pacific, the first test of a thermonuclear device. Even ...
Orange Herald fireball and subsequent mushroom cloud, film reel captured from a trailing aircraft. Orange Herald was a British nuclear weapon, tested on 31 May 1957.At the time it was reported as an H-bomb, although in fact it was a large boosted fission weapon and remains to date, the largest fission device ever detonated.
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 visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
