W50 (nuclear Warhead)
The W50 was an American thermonuclear warhead used on the MGM-31 Pershing short range nuclear missile. It was also used on the LIM-49 Nike Zeus anti-ballistic missile, but this program was cancelled before deployment. The W50 was developed by the Los Alamos National Laboratory. There were two major variants produced (Mod 1, Mod 2), in three yield options (the Y1 with 60 kiloton yield, Y2 with 200 kiloton yield, and Y3 with 400 kiloton yield). All variants were in diameter and long, weighing . The W50 used the Tsetse primary The Tsetse was a small American nuclear bomb developed in the 1950s that was used as the primary in several US thermonuclear bombs and as a small stand-alone weapon of its own. The Tsetse had a boosted composite core which used 2.25 kg Pu-239, 1. ... design for its first fission stage, along with several mid and late 1950s designs. The W50 is thought to have been the source of the W78 warhead's fusion second stage design. The W50 was manufactured from ...

Thermonuclear Bomb
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. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 (). The first full-scale thermonuclear test was carried out by the United States in 1952; the concept has since been employed by most of the world's nuclear powers in the design of their weapons. Modern fusion weapons consist essentially of two main components: a nuclear fission primary stage (fueled by or ) and a separate nuclear fusion secondary stage containing thermonuclear fuel: the heavy hydrogen isotopes deuterium and tritium, or in modern weapons lithium deuteride. ...

MGM-31 Pershing
The MGM-31A Pershing was the missile used in the Pershing 1 and Pershing 1a field artillery missile systems. It was a solid-fueled two-stage theater ballistic missile designed and built by Martin Marietta to replace the PGM-11 Redstone missile as the primary nuclear-capable theater-level weapon of the United States Army and replaced the MGM-1 Matador cruise missiles operated by the German Air Force. Pershing later replaced the European-based MGM-13 Mace cruise missiles deployed by the United States Air Force and the German Air Force. Development began in 1958, with the first test missile fired in 1960, the Pershing 1 system deployed in 1963 and the improved Pershing 1a deployed in 1969. The U.S. Army replaced the Pershing 1a with the Pershing II Weapon System in 1983 while the German Air Force retained Pershing 1a until all Pershings were eliminated in 1991. The U.S. Army Missile Command (MICOM) managed the development and improvements while the Field Artillery Branch deployed the ...

LIM-49 Nike Zeus
Nike Zeus was an anti-ballistic missile (ABM) system developed by the US Army during the late 1950s and early 1960s that was designed to destroy incoming Soviet intercontinental ballistic missile warheads before they could hit their targets. It was designed by Bell Labs' Nike team, and was initially based on the earlier Nike Hercules anti-aircraft missile. The original, Zeus A, was designed to intercept warheads in the upper atmosphere, mounting a 25 kiloton W31 nuclear warhead. During development, the concept changed to protect a much larger area and intercept the warheads at higher altitudes. This required the missile to be greatly enlarged into the totally new design, Zeus B, given the tri-service identifier XLIM-49, mounting a 400 kiloton W50 warhead. In several successful tests, the B model proved itself able to intercept warheads, and even satellites. The nature of the strategic threat changed dramatically during the period that Zeus was being developed. Originally expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear weapon, nuclear, Chemical weapon, chemical, Bioagent, biological, or conventional weapon, conventional warheads in a ballistics, ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs). Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (renamed in 2017 to A-235) is used for the defense of Moscow. It became operational in 1995 and was preceded by the A-35 anti-ballistic missile system. The system uses ABM-4 Gorgon, Gorgon and Gazelle (missile), Gazelle missiles pre ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsetse Primary
The Tsetse was a small American nuclear bomb developed in the 1950s that was used as the primary in several US thermonuclear bombs and as a small stand-alone weapon of its own. The Tsetse had a boosted composite core which used 2.25 kg Pu-239, 1.4kg U-235 and 6g tritium. The nominal yield was 10 kilotons. The design was shared with the UK where the anglicised version was known as Tony. The difference between Tsetse and Tony was in the high explosives used. The UK considered the PBX 9404 too shock sensitive and replaced it by EDC-11. This reduced the nominal yield to 8.5 kilotons. The Tsetse primary was used in the US B43 nuclear bomb, W44 nuclear warhead, W50 nuclear warhead, B57 nuclear bomb, and W59 nuclear warhead, according to researcher Chuck Hansen. After deployment of the B43 two problems were identified in the primary. In 1961 Los Alamos scientists concluded that the primary was not one point safe under all conditions. A long series of tests was needed to develop a sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
