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 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 ...
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 ...
Trinity, part of the Manhattan Project, was the first ever nuclear explosion. The United States performed nuclear weapons tests from 1945 to 1992 as part of the nuclear arms race . By official count, there were 1,054 nuclear tests conducted, including 215 atmospheric and underwater tests.
The court followed up its momentous ruling on affirmative action Thursday with another sweeping decision throwing out President Joe Biden’s $430 billion student loan forgiveness plan, setting ...
Silbervogel: Nazi Germany space weapon project. Orbital weaponry is any weapon that is in orbit around a large body such as a planet or moon. As of December 2022, there are no known operative orbital weapons systems, but several nations have deployed orbital surveillance networks to observe other nations or armed forces.
The false claim that a 14-year-old student built an atomic bomb as a science project originates from a satirical website.
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 ...
