The M202 FLASH ("Flame Assault Shoulder") [3] is an American rocket launcher manufactured by Northrop Corporation, designed to replace the World War II–vintage flamethrowers (such as the M1 and the M2) that remained the military's standard incendiary devices well into the 1980s. The XM202 prototype launcher was tested in the Vietnam War, as part of the XM191 system. [4]

History

The United States Army issued M202s as needed, with each rifle company's headquarters being authorized a single launcher, generally issued as one per rifle platoon. While vastly more lightweight than the M2 flamethrower it replaced, the weapon was still bulky to use and the ammunition suffered from reliability problems. As a result, the weapon had mostly been relegated to storage by the mid-1980s, even though it nominally remains a part of the U.S. Army arsenal.

In USMC service, the M202 was issued to dedicated teams of 0351 Assaultman at the battalion level. The Weapons Platoon's assault section contained three squads, each with a launcher team. [5] With the introduction of the SMAW in the mid 1980s, the M202 was phased out and replaced by SMAW launchers.

The M202A1 has been among weapons listed on the inventory of U.S. units in the War in Afghanistan. [6] [ dead link ]

Design

The M202A1 features four tubes that can load 66 mm incendiary rockets. [7] The M-74 rockets are equipped with M235 warheads, containing approximately 1.34 pounds (610 g) of an incendiary agent. The substance, often mistaken for napalm [ citation needed ], is in fact TPA (thickened pyrophoric agent).

TPA is triethylaluminum (TEA) thickened with polyisobutylene, in the presence of n-hexane, preventing spontaneous combustion after the warhead rupture. TEA, an organometallic compound, is pyrophoric and burns spontaneously at temperatures of 1600 °C (2912 °F) when exposed to air. It burns "white hot" because of the aluminum, much hotter than gasoline or napalm. The light and heat emission is very intense and can produce skin burns from some (close) distance without direct contact with the flame, by thermal radiation alone. A crowd control agent round using CS gas, the XM96, was trialed, but never entered service.[ citation needed ]

The weapon is meant to be fired from the right shoulder, and can be fired from either a standing, crouching, or prone position. It is loaded with a clip which holds a set of four rockets together, which is inserted into the rear of the launcher and can be pushed past the launching position to enable the launcher to be carried while loaded more easily.

<span class="mw-page-title-main">Napalm</span> Gelled incendiary mixture

Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical. The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of naphthenic acid and palmitic acid. A team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in 1942 in a secret laboratory at Harvard University. Of immediate first interest was its viability as an incendiary device to be used in fire bombing campaigns during World War II; its potential to be coherently projected into a solid stream that would carry for distance resulted in widespread adoption in infantry and tank/boat mounted flamethrowers as well.

<span class="mw-page-title-main">Rocket-propelled grenade</span> Shoulder-launched anti-tank weapon

A rocket-propelled grenade (RPG) is a shoulder-fired rocket weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front.

<span class="mw-page-title-main">Flamethrower</span> Ranged incendiary device designed to project a controllable stream of fire

A flamethrower is a ranged incendiary device designed to project a controllable jet of fire. First deployed by the Byzantine Empire in the 7th century AD, flamethrowers saw use in modern times during World War I, and more widely in World War II as a tactical weapon against fortifications.

<span class="mw-page-title-main">Bazooka</span> Man-portable recoilless rocket antitank weapon

The Bazooka is a man-portable recoilless anti-tank rocket launcher weapon, widely deployed by the United States Army, especially during World War II. Also referred to as the "stovepipe", the innovative Bazooka was among the first generation of rocket-propelled anti-tank weapons used in infantry combat. Featuring a solid-propellant rocket for propulsion, it allowed for high-explosive anti-tank (HEAT) shaped charge warheads to be delivered against armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or mine. The universally applied nickname arose from the weapon's M1 variant's vague resemblance to the musical instrument called a bazooka invented and popularized by 1930s American comedian Bob Burns.

<span class="mw-page-title-main">Incendiary device</span> Weapons intended to start fires

Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires. They may destroy structures or sensitive equipment using fire, and sometimes operate as anti-personnel weaponry. Incendiaries utilize materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often called "bombs", they are not explosives but in fact operate to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm, for example, is petroleum especially thickened with certain chemicals into a gel to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.

<span class="mw-page-title-main">Shoulder-fired missile</span> Shoulder mounted recoilless launcher system for shells, unguided or guided rockets (missiles), etc

Shoulder-fired missile, shoulder-launched missile or man-portable missile, among other variants, are common slang terms to describe high-caliber shoulder-mounted weapons systems; that is, weapons firing large, heavy projectiles ("missiles"), typically using the backblast principle, which are small enough to be carried by a single person and fired while held on one's shoulder. The word "missile" in this context is used in its original broad sense of a heavy projectile, and encompasses all shells and rockets, guided or unguided. A more formal variant is simply shoulder-fired weapons system and the like.

The Mk 153 Shoulder-Launched Multipurpose Assault Weapon (SMAW) is a smoothbore shoulder-fired rocket launcher. It is a portable assault weapon and has a secondary anti-armor ability. Developed from the B-300, it was introduced to the United States Armed Forces in 1984. Compared to the Israel Military Industries' B-300 weapon that it was developed from, the SMAW has slower projectile velocities, it and its ammunition are both heavier, and it takes a second crew member to keep up with the B-300's rate-of-fire, but some of its projectile options have longer ranges than the B-300.

The M47 Dragon, known as the FGM-77 during development, is an American shoulder-fired, man-portable anti-tank guided missile system. It was phased out of U.S. military service in 2001, in favor of the newer FGM-148 Javelin system.

<span class="mw-page-title-main">M2 flamethrower</span> Flamethrower

The M2 flamethrower was an American, man-portable, backpack flamethrower that was used in World War II, the Korean War, and the Vietnam War. The M2 was the successor to the M1 and M1A1 flamethrowers. Although its burn time was around 7 seconds long, and the flames were effective around 20–40 meters, it was still a useful weapon. With the arrival of flamethrower tanks, the need for flamethrower-carrying infantrymen to expose themselves to enemy fire had been greatly reduced.

<span class="mw-page-title-main">RPO-A Shmel</span> Missile launcher

The RPO-A Shmel is a man-portable, single-use, rocket-assisted thermobaric weapon. While its name directly translates to flamethrower, the RPO-A Shmel is more accurately described as a thermobaric weapon. The Shmel is designed, produced and exported by the Russian Federation and previously by the Soviet Union. It entered service with the Soviet Armed Forces at the end of the 1980s as the successor for the RPO Rys.

<span class="mw-page-title-main">B-300</span> Anti-tank weapon

The B-300 is a reusable man-portable anti-tank weapon system developed by Israel Military Industries in the late 1970s for use by the Israel Defense Forces. The B-300 can be carried and operated by a single operator and is effective to approximately 400 meters (1,312 ft). Pre-packaged munitions and simple operating mechanisms make the weapon quite versatile, permitting use by airborne, motorized, and ground troops alike. When defence publications first heard reports of the B-300 in the early 1980s, various reports stated in error that it was an improved Israeli manufactured version of the Russian RPG-7.

The M31 HEAT is a fin-stabilized anti-tank rifle grenade designed in the late 1950s to replace the Belgian ENERGA rifle grenade which was adopted by the US Army and US Marines as an emergency stop-gap measure during the Korean War. Like the ENERGA, it has a nose-initiated, based-detonated HEAT warhead, but unlike the ENERGA, the mechanical impact fuse system is replaced with a less complex and more reliable piezo-electric fuse system which also allows higher angles of impact, up to 65 degrees.

The M1 and M1A1 were portable flamethrowers developed by the United States during World War II. The M1 weighed 72 lb, had a range of 15 meters, and had a fuel tank capacity of five gallons. The improved M1A1 weighed less, at 65 lb, had a much longer range of 45 meters, had the same fuel tank capacity, and fired thickened fuel (napalm).

<span class="mw-page-title-main">AT4</span> Disposable anti-tank launcher

The AT4 is a Swedish 84 mm (3.31 in) unguided, man-portable, disposable, shoulder-fired recoilless anti-tank weapon manufactured by Saab Bofors Dynamics. The AT4 is not a rocket launcher strictly speaking, because the explosive warhead is not propelled by a rocket motor. Rather, it is a smooth-bore recoilless gun. Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world. The M136 AT4 and M136A1 AT4CS-RS are the variants used by the United States Army.

The DZJ-08 is a portable, disposable, unguided, shoulder-launched, multipurpose recoilless weapon. The weapon is designed as a multi-role assault weapon aiming to provide anti-armor, anti-fortification, and anti-personnel capability.

<span class="mw-page-title-main">M9 flamethrower</span> Flamethrower

The M9 flamethrower, officially designated: Flame Thrower, Portable, M9-7, was an American man-portable flamethrower that essentially replaced the earlier M2 flamethrower variants. The set consisted of the M9 backpack, the M8 quick-connect hose, and the newer M7 gun group. The M9-7 solved many of the problems associated with the M1 and M2 variants by reducing the overall mass and featuring a shorter gun group. It was the last flamethrower in U.S. service and was replaced with the M202 FLASH rocket-based incendiary system.
