40mm
40 mm grenade (also styled 40mm grenade) is a generic class-name for grenade launcher ammunition ( subsonic shells) in caliber. The generic name stems from the fact that several countries have developed or adopted grenade launchers in 40 mm caliber. This is a general collection of the world's many different "40 mm grenades". NATO NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers. 40×46 mm LV (40 mm low velocity) ''40×46 mm LV'' (''low velocity'') is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, and Heckler & Koch AG36. The propellant has low pressure and gives the projectile an average velocity of depending on the ammuniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M203 Grenade Launcher
The M203 is a single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 break-action grenade launcher, which utilizes the high-low propulsion system to keep recoil forces low. Quite versatile and compatible with many rifle models, the M203 was originally designed for the U.S. M16 and its carbine variant, the M4. The launcher can also be mounted onto a C7, a Canadian version of the M16 rifle; however, this requires the prior removal of the bottom handguard. Stand-alone variants of the M203 exist, as do versions designed specifically for many other rifles. The device attaches under the barrel, the launcher trigger being in the rear of the launcher, just forward of the rifle magazine. The rifle magazine functions as a hand grip when firing the M203. A separate, right-handed only, sighting system is added to rifles fitted with the M203, as the rifle's standard sights are not matched to the launcher. The v ...

Grenade Launcher
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices which could be referred to as grenade launchers were slings, which could be used to throw early ''grenado'' fuse bombs. The a ...

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 60mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milkor MGL
The Milkor MGL (Multiple Grenade Launcher) is a lightweight 40 mm six-shot revolver-type grenade launcher (variations also fire 37/38mm) developed and manufactured in South Africa by Milkor (Pty) Ltd. The MGL was demonstrated as a concept to the South African Defence Force (SADF) in 1981. The MGL was then officially accepted into service with the SADF as the Y2. After its introduction in 1983, the MGL was gradually adopted by the armed forces and law enforcement organizations of over 50 countries. Total production since 1983 has been more than 50,000 units. The MGL is a multiple-shot weapon, intended to significantly increase a small squad's firepower when compared to traditional single-shot grenade launchers like the M203. The MGL is designed to be simple, rugged, and reliable. It uses the well-proven revolver principle to achieve a high rate of accurate fire which can be rapidly brought to bear on a target. A variety of rounds such as HE, HEAT, anti-riot baton, irritant, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M79 Grenade Launcher
The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War. Because of its distinctive report, it has earned the nicknames of "Thumper", "Thump-Gun", "Bloop Tube", "Big Ed", "Elephant Gun," and "Blooper" among American soldiers as well as "Can Cannon" in reference to the grenade size; Australian units referred to it as the "Wombat Gun". The M79 can fire a wide variety of 40 mm rounds, including explosive, anti-personnel, smoke, buckshot, flechette (pointed steel projectiles with a vaned tail for stable flight), and illumination. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles. History The M79 was a result of the US Army's Project Niblick, an attempt to increase firepower for the infantryman by having an explosive project ...

Heckler & Koch AG36
The AG36 is a single-shot 40 mm grenade launcher that operates on the high-low system and was designed primarily for installation on the G36 assault rifle, designed by the German weapons manufacturing company Heckler & Koch of Oberndorf am Neckar. It originally appeared as Heckler & Koch's candidate for the US Army's Enhanced Grenade Launcher requirement, evaluated for use with the XM8 and FN SCAR rifles. As is commonly mistaken, the "A" is not an addition to the name "G36", which is short for ''Gewehr 36'', but is in fact an abbreviation of the German ''Anbaugranatwerfer'', literally meaning "attached grenade launcher" and the 36 coming from the name of the primary weapon it was designed to enhance – the G36. It can also be used dismounted, with a stock attached as a stand-alone model, or a LLM01 laser light module can be attached to it. Design details As in many modern weapon systems, including the G36 series, extensive use of polymers and high-strength aluminium in the ...

High–low System
The high–low system (or high–low pressure system, high–low propulsion system, high–low projection system) is a design of cannon and anti-tank warfare launcher using a smaller high-pressure chamber to store propellant. It allows a much larger projectile to be launched without the heavy equipment usually needed for large caliber weapons. When the propellant is ignited, the higher pressure gases are bled out through vents (or ports) at reduced pressure to a much larger low pressure chamber to push a projectile forward. The high-low system allows the weight of the weapon and its ammunition to be reduced significantly. Production cost and time are drastically lower than for standard cannon or other small-arm weapon systems firing a projectile of the same size and weight. It has a far more efficient use of the propellant, unlike earlier recoilless weapons, where most of the propellant is expended to the rear of the weapon to counter the recoil of the projectile being fired.

Octol
{{Short description, A high explosive mixture consisting of HMX and TNT Octol is a melt-castable, high explosive mixture consisting of HMX and TNT in different weight proportions. Composition Two formulations are commonly used: * 70% HMX & 30% TNT * 75% HMX & 25% TNT Given that HMX has a much higher detonation velocity than TNT (over 2,000 metres per second faster) and forms the main part of this explosive blend, the brisance characteristics of Octol can be inferred. Applications The applications of Octol are generally military; e.g., shaped charges and warheads used in guided missiles and submunitions. Octol is somewhat more expensive than RDX-based explosives, such as Composition B and Cyclotol. The advantage of Octol is that it significantly reduces the size and weight of the explosive charge required. These are important considerations where smart weapons such as guided missiles are concerned. A light (but effective) warhead means a superior power to weight ratio. This in ...

Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Battlefield Illumination
Battlefield illumination is technology that improves visibility for military forces operating in difficult low-light conditions. The risks and dangers to armies fighting in poor light have been known since Ancient Chinese times. Prior to the advent of the electrical age, fire was used to improve visibility on the battlefield. Modern armies use a variety of equipment and discharge devices to create artificial light. If natural light is not present searchlights, whether using visible light or infrared, and flares can be used. As light can be detected electronically, modern warfare has accordingly seen increased use of night vision through the use of infrared cameras and image intensifiers. Theory Ancient military strategists knew that natural light created shadows that can hide form while bright areas would expose a military force's size and number. Ancient armies would always prefer to fight with the Sun behind them in order to use the visual glare to partially blind an opposing ...
