Kinglet Primary
Kinglet was a boosted fission primary used in several American thermonuclear weapons. The W55 warhead for the UUM-44 SUBROC anti-submarine missile and the W58 warhead for Polaris A-3 were designed to use Kinglet, while the W47 warhead for Polaris A-1/A-2 were retrofitted with Kinglet to overcome the technical issues with the Robin primary the W47 was initially deployed with. Allegedly, only the W47Y2 was converted to the Mod 3 design using Kinglet. Design The Kinglet device was approximately in diameter, in length and weighed approximately . The device was of the two-point design. Two-point devices only require two detonators to fire the whole device, compared to earlier nuclear weapons that required tens of detonators. Characteristics of the warheads that used Kinglet are: See also * List of nuclear weapons * Teller-Ulam design * Tsetse primary * Python primary According to researcher Chuck Hansen, the W34 Python was a gas-boosted fission primary used in several designs of ...

Thermonuclear Weapon
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 ...

UUM-44 SUBROC
The UUM-44 SUBROC (SUBmarine ROCket) was a type of submarine-launched rocket deployed by the United States Navy as an anti-submarine weapon. It carried a 250 kiloton thermonuclear warhead configured as a nuclear depth bomb. Development SUBROC was one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. Development began in 1958, with the technical evaluation being completed in 1963. SUBROC reached Initial Operation Capability (IOC) aboard the attack submarine ''Permit'' in 1964. When SUBROC reached IOC, the US Navy's admiral in charge of weapons procurement stated that SUBROC was "…a more difficult technical problem than Polaris." Operation SUBROC could be launched from a 21-inch submarine torpedo tube. After launch, the solid fuel rocket motor fired and SUBROC rose to the surface. The launch angle then changed and SUBROC flew to its destination following a predetermined ballistic trajectory. At a predetermined ti ...

UGM-27 Polaris
The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army, and had influenced the design by making it squat so it would fit in submarines. However, they had concerns about the use of liquid fuel rockets on board ships, and some consideration was given to a solid fuel version, Jupiter S. In 1956, during an anti-submarine study known as Project Nobska, Edward Teller suggested that very small hydrogen bomb warheads were possible. A crash program to develop a missile suitable for carrying such warheads began as Polaris, launching its first shot less than four years later, in February 1960. As the Polaris missile was fired underwater from a moving platform, it was essentially invulnerable to counterattack. This led the Navy to suggest, starting around 1959, that they be g ...

Robin (nuclear Primary)
The Robin was the common design nuclear fission bomb core for several Cold War designs for American nuclear and thermonuclear weapons, according to researcher Chuck Hansen. Primary is the technical term for the fission bomb component of a thermonuclear or fusion bomb, which is used to start the reactions going and implode and detonate the second, fusion stage. The Robin design was used as the W45 nuclear warhead, and as the primary (stage) in the W38 and W47 thermonuclear weapons. Andreas Parsch, 2005, accessed Dec 11, 2007 It has been associated with the nuclear warhead, but this is probably an error. History The Robin is apparently a weaponized versio ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Hardtack I
Operation Hardtack I was a series of 35 nuclear tests conducted by the United States from April 28 to August 18 in 1958 at the Pacific Proving Grounds. At the time of testing, the Operation Hardtack I test series included more nuclear detonations than the total of prior nuclear explosions in the Pacific Ocean. These tests followed the '' Project 58/58A'' series, which occurred from 1957 December 6 to 1958, March 14, and preceded the Operation Argus series, which took place in 1958 from August 27 to September 6. Operation Hardtack I was directed by Joint Task Force 7 (JTF 7). JTF-7 was a collaboration between the military and many civilians, but was structured like a military organization. Its 19,100 personnel were composed of members of the US military, federal civilian employees, as well as workers affiliated with the Department of Defense (DOD) and the Atomic Energy Commission (AEC). There were three main research directions. The first was the development of new types of nucl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. United States US nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W-91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other r ...

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] |
Python Primary
According to researcher Chuck Hansen, the W34 Python was a gas-boosted fission primary used in several designs of American thermonuclear weapons. Hansen's research indicates that the W34 Python primary was used in the US B28 nuclear bomb, W28, W40, and W49, and as a boosted fission warhead without a thermonuclear second stage in several other weapons. These were the Mark 45 ASTOR wire-guided , submarine-launched heavyweight torpedo; the Mark 101 Lulu nuclear depth bomb; the Mark 105 Hotpoint laydown bomb. Additionally, an anglicised W34 Python known to the British as 'Peter' was manufactured in Britain as the primary for Red Snow, itself an anglicised W28 warhead. Peter was also proposed as a replacement for the Red Beard warhead housed in a Red Beard carcass, and as the Violet Mist nuclear land mine for the British Army in Germany. The W34 used the melt-cast high explosive Octol, a variant of HMX and TNT as the material for its implosion lenses, and this relatively unsophist ...
