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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermal Battery
A thermal energy battery is a physical structure used for the purpose of storing and releasing thermal energy—see also thermal energy storage. Such a thermal battery (a.k.a. TBat) allows energy available at one time to be temporarily stored and then released at another time. The basic principles involved in a thermal battery occur at the atomic level of matter, with energy being added to or taken from either a solid mass or a liquid volume which causes the substance's temperature to change. Some thermal batteries also involve causing a substance to transition thermally through a phase transition which causes even more energy to be stored and released due to the delta enthalpy of fusion or delta enthalpy of vaporization. History of thermal batteries Thermal batteries are very common, and include such familiar items as a hot water bottle. Early examples of thermal batteries include stone and mud cook stoves, rocks placed in fires, and kilns. While stoves and kilns are ove ...

Cold War Rockets Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Nuclear Artillery
Nuclear artillery is a subset of limited- yield tactical nuclear weapons, in particular those weapons that are launched from the ground at battlefield targets. Nuclear artillery is commonly associated with shells delivered by a cannon, but in a technical sense short-range artillery rockets or tactical ballistic missiles are also included. The development of nuclear artillery was part of a broad push by nuclear weapons countries to develop nuclear weapons which could be used tactically against enemy armies in the field (as opposed to strategic uses against cities, military bases, and heavy industry). Nuclear artillery was both developed and deployed by a small group of states, including the United States, the Soviet Union, and France. The United Kingdom planned and partially developed such weapon systems (the Blue Water missile and the Yellow Anvil artillery shell) but did not put them into production. A second group of states has derivative association with nuclear artille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-surface Missiles Of The United States
A surface-to-surface missile (SSM) or ground-to-ground missile (GGM) is a missile designed to be launched from the ground or the sea and strike targets on land or at sea. They may be fired from hand-held or vehicle mounted devices, from fixed installations, or from a ship. They are often powered by a rocket engine or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may use body lift or fly a ballistic trajectory. The V-1 flying bomb was the first operational surface-to-surface missile. Contemporary surface-to-surface missiles are usually guided. An unguided surface-to-surface missile is usually referred to as a rocket (for example, an RPG-7 or M72 LAW is an anti-tank rocket whereas a BGM-71 TOW or AT-2 Swatter is an anti-tank guided missile). Examples of surface-to-surface missile include the MGM-140 ATACMS, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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. The MADM warhead was designed to be economical in nuclear material, having a diameter of less than , and it was hoped that the device ...

157th Maneuver Enhancement Brigade
The 157th Maneuver Enhancement Brigade, also known as the Iron Brigade, is based out of Milwaukee, Wisconsin. It was formerly known as the 57th Field Artillery Brigade, at which time its subordinate organizations included the 1st Battalion, 126th Field Artillery Regiment and the 1st Battalion, 121st Field Artillery Regiment from the Wisconsin Army National Guard, plus the 1st Battalion, 182nd Field Artillery Regiment of the Michigan Army National Guard. Not to be confused with the famous "Iron Brigade" of the Civil War, its nickname was traditionally given to crack artillery units in the Civil War. It was during World War I that the 57th Field Artillery Brigade earned its nickname as it spent many hours at the front and fired more artillery rounds than any brigade in the American Army. History 20th century World War I era Part of the 32nd Infantry Division, the unit was organized under War Department orders of 18 July 1917, from National Guard troops from Wisconsin and Michigan ...

Douglas Aircraft Company
The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas; it then operated as a division of McDonnell Douglas. McDonnell Douglas later merged with Boeing in 1997. History 1920s The company was founded as the Douglas Company by Donald Wills Douglas Sr. on July 22, 1921 in Santa Monica, California, following dissolution of the Davis-Douglas Company. An early claim to fame was the first circumnavigation of the world by air in Douglas airplanes in 1924. In 1923, the U.S. Army Air Service was interested in carrying out a mission to circumnavigate the Earth for the first time by aircraft, a program called "World Flight". Donald Douglas proposed a modified Douglas DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been produced for the U.S. Navy.Rumerman, Judy.

Lanyard
A lanyard is a cord, length of webbing, or strap that may serve any of various functions, which include a means of attachment, restraint, retrieval, and activation and deactivation. A lanyard is also a piece of rigging used to secure or lower objects aboard a ship."lanyard lan-yrd." Merriam-Webster's Collegiate(R) Dictionary. Springfield: Merriam-Webster, 2004. Credo Reference. Web. 1 October 2012. Origins The earliest references to lanyards date from 15th century France: "lanière" was a thong or strap-on apparatus. Bosun's pipe, marlinspike, and small knives typically had a lanyard consisting of a string loop tied together with a diamond knot. It helped secure against fall and gave an extended grip over a small handle. In the French military, lanyards were used to connect a pistol, sword, or whistle (for signaling) to a uniform semi-permanently. Lanyards were used by mounted cavalry on land and naval officers at sea. A pistol lanyard can be easily removed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
