Fléchette
A flechette ( ) is a pointed steel projectile with a vaned tail for stable flight. The name comes from French , "little arrow" or "dart (missile), dart", and sometimes retains the acute accent in English: fléchette. They have been used as ballistic weapons since World War I. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial. Air-dropped During World War I, flechettes were dropped from aircraft to attack infantry and were able to pierce helmets. Later the U.S. used Lazy Dog (bomb), Lazy Dog bombs, which are small, unguided kinetic projectiles typically about in length, in diameter, and weighing about . The weapons were designed to be dropped from an aircraft. They contained no explosive charge but as they fell they developed significant kinetic energy making them lethal and able to easily penetrate soft cover such as jungle canopy, sev ...

Advanced Combat Rifle
The Advanced Combat Rifle (ACR) was a United States Army program, started in 1986, to find a replacement for the M16 assault rifle. Under the stress of battle the average soldier with an M16 may shoot a target at 45 meters, but hit probability is reduced to one out of ten shots on target by 220 meters. Because of this, the ACR program was initiated in the late 1980s to create a weapon that could double the hit probability. The ACR program was preceded by older programs such as the Special Purpose Individual Weapon. The program ended in 1990 after an expenditure of approximately US$300 million. Phase I and II Phase I of the program started in February 1986 when development contracts were placed with six companies: AAI Corporation, Ares Incorporated, Colt's Manufacturing Company, Heckler & Koch (H&K), McDonnell Douglas Helicopter Systems (MDHS), and Steyr Mannlicher. Two weapons were cut from the list before Phase II started. The companies started an appeals process and were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Purpose Individual Weapon
The Special Purpose Individual Weapon (SPIW) was a long-running United States Army program to develop, in part, a workable flechette-firing "rifle", though other concepts were also involved. The concepts continued to be tested under the Future Rifle Program and again in the 1980s under the Advanced Combat Rifle program, but neither program resulted in a system useful enough to warrant replacing the M16. Project SALVO The idea of a flechette-firing individual weapon started in earnest during the Army's Project SALVO. SALVO had earlier concluded that a small weapon with a high rate of fire would be considerably deadlier than the large "full power" weapons being developed in the 1950s, and followed several lines of investigation to find the best way to provide high firing rates. SALVO had a small number of "duplex load" weapons developed, where two bullets were stacked, while Springfield Armory and Olin/Winchester both entered multiple barrel firearms. Even before the SALVO tests, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beehive Anti-personnel Round
Beehive was a Vietnam war era anti-personnel round packed with metal flechettes fired from an artillery gun most popularly deployed during that conflict. It is also known as flechette rounds or their official designation, antipersonnel-tracer (APERS-T). Typically, artillery gunners fire using indirect fire, firing at targets they cannot see by line of sight, with information provided by a forward observer. However, during the Vietnam War, there was a demand for a munition that could be fired directly at enemy troops, in cases where an artillery unit was attacked. History The flechette rounds were developed under a contract administered by Picatinny Arsenal and let to the Whirlpool Corporation in April 1957. The contract was named the "Beehive Program" referring to the way the flechettes were compartmentalized and stacked, looking like the traditional image of a conical beehive. It was commonly assumed by users in the service that the term referred to a supposed 'buzzing' sound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery
Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'', ''gun artillery'', or - a layman t ...

American Rifleman
''American Rifleman'' is a United States-based monthly shooting and firearms interest publication, owned by the National Rifle Association (NRA). It is the 33rd-most-widely-distributed consumer magazine and the NRA's primary magazine. The magazine has its headquarters in Fairfax, Virginia. History Arthur Corbin Gould, an avid shooter and member of the Massachusetts Rifle Association, published ''The Rifle'' in 1885 as an effort to focus discussion on the sport of rifle shooting. ''The Rifle'' later changed its title to ''Shooting and Fishing'' in 1888, branching out into other outdoor sports. In 1894, while the magazine was titled ''Shooting and Fishing'', Gould attended the National Rifle Association matches held at Sea Girt and was impressed with the level of competition, leading him to write several editorials urging the public to join. This call eventually led to the revitalization of the National Rifle Association and established a Board of Directors to help manage the ...

Federal Cartridge Company
Federal Premium Ammunition is a wholly owned subsidiary of Vista Outdoor, located in Anoka, Minnesota. With a workforce of nearly 1,500, Federal manufactures shotshell, centerfire, and rimfire ammunition and components. History On April 27, 1922, Charles L. Horn took control of a small plant in Anoka, Minnesota and refounded Federal Cartridge Corporation. Horn launched a distribution plan that involved merchandising Federal products in grocery stores, barbershops, and filling stations. In 1941, Federal won an $87 million contract from the United States government (approx. $1.3 billion in 2010) to build and operate the $30 million Twin City Ordnance Plant. Federal ranked 59th among United States corporations in the value of World War II military production. In 1977, William B. Horn introduced Federal's Premium line of centerfire rifle and shotshell ammunition. Federal also owned Hoffman Engineering, a company that made electronic enclosures. In 1985, Federal was sold to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Cartridge Company
The Western Cartridge Company is an American manufacturer of small arms and ammunition that is based in East Alton, Illinois. Founded in 1898, it was the forerunner of the Olin Corporation, formed in 1944, of which Western is still a subsidiary. Western acquired the Winchester Repeating Arms Company after Winchester went into receivership in 1931. History Franklin W. Olin received an engineering degree from Cornell University in 1886. After working at powder mills in the eastern United States, he was one of several investors establishing the Equitable Powder Company in 1892 at East Alton, Illinois. Production of blasting powder for southern Illinois coal mining began in 1893. Olin formed the Western Cartridge Company in 1898 to manufacture sporting rifle powder and shotgun shells for settlers of the Great Plains. The shotgun shells used primers manufactured by larger eastern ammunition firms. When the firms with primer manufacturing facilities raised primer prices in 1900 to r ...

Combat Shotgun
A combat shotgun is a shotgun issued by militaries for warfare. The earliest shotguns specifically designed for combat were the trench guns or trench shotguns issued in World War I. While limited in range, the multiple projectiles typically used in a shotgun shell provide increased hit probability unmatched by other small arms. History While the sporting shotgun traces its ancestry back to the fowling piece, which was a refinement of the smoothbore musket, the combat shotgun bears more kinship to the shorter blunderbuss. Invented in the 16th century by the Dutch, the blunderbuss was used through the 18th century in warfare by the British, Austrian, Spanish (like the Escopeteros Voluntarios de Cadiz, formed in 1804 or the Compañía de Escopeteros de las Salinas, among others) and Prussian regiments, as well as in the American colonies. As use of the blunderbuss declined, the United States military began loading smaller lead shot (buckshot) in combination with their large ...

Gauge (bore Diameter)
The gauge (or commonly bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8-pounder would fire an 8 lb (3.6 kg) ball. Gauge is commonly used today in reference to shotguns, though historically it was also used in large double rifles, which were made in sizes up to 2 bore during their heyday in the 1880s, being originally loaded with black powder cartridges. These very large rifles, called "elephant guns", were intended for use primarily in Africa and Asia for hunting lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
