W45
The W45 was a multipurpose American nuclear warhead developed in the early 1960s, first built in 1962 and fielded in some applications until 1988. It had a diameter of 11.5 inches (292 mm), a length of 27 inches (686 mm) and weighed 150 pounds (68 kg). The yields of different W45 versions were 0.5, 1, 5, 8, 10, and 15 kilotons. The W45 was designed at the Livermore branch of the University of California Radiation Laboratory (UCRL), now Lawrence Livermore National Laboratory. The W45 used a common nuclear fission core called the Robin primary, which was used as the fission primary in the thermonuclear W38 and W47 weapons. Applications of the W45 warhead included: * Little John SSM * Terrier SAM * Medium Atomic Demolition Munition or MADM * Bullpup ASM See also * List of nuclear weapons This is a list of nuclear weapons listed according to country of origin, and then by type within the states.

Medium Atomic Demolition Munition (internal)
Medium Atomic Demolition Munition (MADM) was a tactical nuclear weapon developed by the United States during the Cold War. It was an Atomic demolition munitions, atomic demolition munition (ADM), a combat engineering device for demolition of structures and for battlefield shaping. The device contained a W45 warhead with an estimated yield of . Each MADM weighed in its transportation container. They were deployed between 1962 and 1986. In service, the MADM was known as the M167, M172 and M175 Atomic Demolition Charges (ADCs). History The history of the MADM began in 1954 with the proposal for a light-weight multi-purpose warhead. Its predecessor, the first atomic demolition munition (ADM), was deployed in the same year. This was a low-yield weapon () used by special forces and commando teams to destroy enemy infrastructure such as bridges tunnels, and harbors, among others.

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 ...

MGR-3 Little John
The MGR-3 Little John was a free flight artillery rocket system designed and put into service by the U.S. Army during the 1950s and 1960s. Description Carried on the XM34 rocket launcher, it could carry either nuclear or conventional warheads. It was primarily intended for use in airborne assault operations and to complement the heavier, self-propelled MGR-1 Honest John rocket. Development of the missile was started at Army's Rocket and Guided Missile Agency laboratory at Huntsville, Alabama, the Redstone Arsenal, in June 1955. In June 1956, the first launch of the XM47 Little John occurred. This initial model was spin-stabilised by larger triangular fins and a longer launch rail. It was stabilised by the fins alone until it began to spin. The production XM51 version had smaller rectangular fins, too small to stabilise the rocket, and was stabilised from launch by a unique "spin-on-straight-rail" system. The XM51 Little John was delivered to the field in November 1961 and rem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-2 Terrier
The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), and was among the earliest surface-to-air missiles to equip United States Navy ships. It underwent significant upgrades while in service, starting with beam-riding guidance with a range at a speed of Mach 1.8, and ending as a semi-active radar homing system with a range of at speeds as high as Mach 3. It was replaced in service by the RIM-67 Standard ER (SM-1ER). Terrier has also been used as a sounding rocket. History The Terrier was a development of the Bumblebee Project, the United States Navy's effort to develop a surface-to-air missile to provide a middle layer of defense against air attack (between carrier fighters and antiaircraft guns). It was test launched from on January 28, 1953, and first deployed operationally on the s, and in the mid-1950s, with ''Canberra'' being the first to achieve operational status June 15, 1956. Its US Navy designation was SAM-N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-12 Bullpup
The AGM-12 Bullpup is a short-range air-to-ground missile developed by Martin Marietta for the US Navy. It is among the earliest precision guided air-to-ground weapons and the first to be mass produced. It first saw operational use in 1959 on the A-4 Skyhawk, but soon found use on the A-6 Intruder, F-100 Super Sabre, F-105 Thunderchief, F-4 Phantom II, F-8 Crusader, and P-3 Orion in both Navy and US Air Force service, as well as NATO allies. The weapon was guided manually via a small joystick in the aircraft cockpit, which presented a number of problems and its ultimate accuracy was on the order of , greater than desired. In the 1960s it was increasingly supplanted by fully automatic weapons like the AGM-62 Walleye and AGM-65 Maverick. History ASM-N-7 Bullpup Development of Bullpup began in 1953 when Korean War experience demonstrated the almost complete inability for conventional bombing to attack point land targets like bridges. There had been great experimentation during Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrence Livermore National Laboratory
Lawrence Livermore National Laboratory (LLNL) is a federal research facility in Livermore, California, United States. The lab was originally established as the University of California Radiation Laboratory, Livermore Branch in 1952 in response to the detonation of the first atomic bomb by the Soviet Union during the Cold War. It later became autonomous in 1971 and was designated a national laboratory in 1981. A federally funded research and development center, Lawrence Livermore Lab is primarily funded by the U.S. Department of Energy and it is managed privately and operated by Lawrence Livermore National Security, LLC (a partnership of the University of California), Bechtel, BWX Technologies, AECOM, and Battelle Memorial Institute in affiliation with the Texas A&M University System. In 2012, the laboratory had the synthetic chemical element livermorium (element 116) named after it. Overview LLNL is self-described as a "premier research and development institution for sci ...

Robin Primary
The Robin was the common design nuclear fission bomb core for several Cold War designs for American nuclear and thermonuclear bomb, thermonuclear weapons, according to researcher Chuck Hansen. Nuclear weapon design#Two-stage thermonuclear weapons, 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 W48 nuclear warhead, but this is probably an error. History The Robin is apparently a weaponized version of the Swan (nuclear primary ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Kiloton
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a tonne, metric ton (1,000 kilograms) of Trinitrotoluene, TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 tera-, terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 peta-, petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various CTBT, n ...
