Mk 20 Mod 0 Grenade Launcher
The Mk 20 Mod 0 was a 40mm automatic grenade launcher manufactured by NOS Louisville which was used by the US Navy during the Vietnam War. It used a blow-forward mechanism that was previously used on semi-automatic pistols such as the Steyr Mannlicher M1894 and Schwarzlose Model 1908. The Mk 20 was eventually replaced by the Mk 19 Mod 3.

War Remnants Museum (Ho Chi Minh City)
The War Remnants Museum ( vi, Bảo tàng chứng tích chiến tranh) is a war museum at 28 Vo Van Tan, in District 3, Ho Chi Minh City (Saigon), Vietnam. It contains exhibits relating to the First Indochina War and the Vietnam War. History Operated by the Ho Chi Minh City government, an earlier version of this museum opened on September 4, 1975, as the Exhibition House for US and Puppet Crimes ( vi, Nhà trưng bày tội ác Mỹ-ngụy). It was located in the former United States Information Agency building. The exhibition was not the first of its kind for the North Vietnamese side, but rather followed a tradition of such exhibitions exposing war crimes, first those of the French and then those of the Americans, who had operated in the country as early as 1954. Formerly known as the "Museum of Chinese and American War Crimes", the name was changed in 1990 to Exhibition House for Crimes of War and Aggression (''Nhà trưng bày tội ác chiến tranh xâm lược''), dropping b ...

Comparison Of Automatic Grenade Launchers
An automatic grenade launcher (AGL) or grenade machine gun is a grenade launcher that is capable of fully automatic fire, and is typically loaded with either an ammunition belt or magazine. These weapons are often mounted on vehicles or helicopters, as when these weapons are moved by infantry the weapon, its tripod, and ammunition, are a heavy load, requiring a small team. Other types of grenade launchers are typically much lighter and can easily be carried by just a single soldier. The Mark 19 Automatic Grenade Launcher, first fielded by the United States in 1966, and still widely used today, weighs 62.5 kg (137.58 lb) when attached to its tripod, and loaded with a box of ammunition. For comparison, the single-shot M79 grenade launcher weighs 2.93 kg (6.45 lb). Regardless of their weight, AGLs are still highly effective, and the Mark 19 is capable of indirect fire up to 2,200 metres, a role traditionally reserved for mortars. Even though the round carries less explosive than a 60 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Guns Of The United States
A machine is a physical system using power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control components a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally " rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mo ...

40×46mm Grenade Launchers
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other ...

It was replaced by the Mk 19 grenade launcher in service with the United States Armed Forces. Design This weapon is a manually-operated, belt-fed. The use of a split breech mechanism allowed the weapon to be light and simple. Employment The Mark 18 was used primarily on small boats or in fixed positions such as bunkers; their primary users were the so-called " river rats" and the SEALs. They could be mounted on M2HB, M60, M1919 tripods, or pintle mounts, but could not be fired without such a mount.

Mk 19 Grenade Launcher
The Mk 19 grenade launcher (pronounced Mark 19) is an American 40 mm belt-fed automatic grenade launcher that was first developed during the Vietnam War. Overview The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully-automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 can launch its grenade at a maximum distance of , though its effective range to a point target is about , since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its ope ...

Schwarzlose Model 1908
The Schwarzlose Model 1908 was a semi-automatic pistol, designed by Andreas Schwarzlose, released in 1908 in the German Empire The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary ... and produced until 1911. Operation The Schwarzlose employs a very distinctive "blow-forward action" operating mechanism. It has no slide, instead the mechanism is operated by the barrel being projected forward due to the gas pressure and the friction of the bullet passing through the bore, the compressed recoil spring drives the barrel back, stripping the top cartridge from the magazine, chambering the round, and pressing the cartridge head against the standing breech, which is part of the frame.

Steyr Mannlicher M1894
The Mannlicher M1894 was an early blow-forward semi-automatic pistol. General features The earliest Ferdinand Mannlicher pistol, manufactured by Fabrique D'Armes de Neuhausen, Switzerland, was designed to be self-loading and to use a special rimmed cartridge in 6.5 mm caliber. The design represented an entirely new utilization of mechanical principles in automatic action called "blow-forward action". In the standard type of automatic action for low-powered cartridges, the recoil (or blow-back) is utilized to drive back a movable breech face or block, but Mannlicher utilized the principle of a rigid standing breech with the barrel blowing forward to extract, eject, and prepare for reloading. A special barrel housing which carries the sight covers the entire length of the barrel (6.49 in/165 mm) when the arm is closed. A heavy recoil spring is mounted concentrically around the barrel within this housing and is compressed between a shoulder at the forward end ...
