M687
The M687 was an American 155 mm binary sarin chemical artillery shell. The design was standardized in 1976 and production began on December 16, 1987 at Pine Bluff Arsenal, Pine Bluff, Arkansas. Production was halted three years later, following the 1990 Chemical Weapons Accord between the United States and the USSR, and the dismantling of existing stocks began in November 1997 at Hawthorne Army Depot, Nevada. America's remaining stocks were stored at the Deseret Chemical Depot, Utah, and the Umatilla Chemical Depot (Umatilla County, Oregon). The shell contained two canisters separated by a rupture disk. The compartments were filled with two liquid precursor chemicals for sarin (GB2): methylphosphonyl difluoride (denominated DF) and a mixture of isopropyl alcohol and isopropyl amine (denominated OPA) is in a second canister. The isopropyl amine binds the hydrogen fluoride generated during the chemical reaction. When the shell was fired the force of the acceleration would cause the ...

Binary Chemical Weapon
__NOTOC__ Binary chemical weapons or munitions are chemical weapons which contain the toxic agent in its active state as chemical precursors that are significantly less toxic than the agent. This improves the safety of storing, transporting, and disposing of the weapon. Commonly, firing the munition removes a barrier between two precursors. These react to form the intended agent which is then aerosolized and distributed by a bursting charge. Binary chemical weapons are chemical weapons within the scope of the Chemical Weapons Convention and therefore their production, use and stockpiling is forbidden in most countries, as at least one of the individual chemicals is likely to be a Schedule 1 chemical for which large scale production is forbidden. Examples One example of a binary chemical weapon is the United States Army M687. In the M687, methylphosphonyl difluoride (military name: DF, a Schedule 1 chemical) and a mixture of two agents held in chambers within the munition, separated ...

M104 155 Mm Projectile
The M104 155 mm projectile is a chemical artillery shell designed for use by the U.S. Army. It was specifically designed to carry about of sulfur mustard (H) or (HD) blister agent (distilled mustard). As early as the 1960s, the shell was also filled with white phosphorus to be used for obscuration and signaling. History and design Following World War I, militaries around the world began working to standardize calibers of ammunition within their countries. In the United States, the military began focusing on replacing the European-made 75 mm artillery shells with 105 mm and 155 mm shells. The M104 (along with the M110, which it shares many design elements with) was designed as a 155 mm artillery shell for use in the M114 howitzer. It is a steel shell with a rotating band near the base, and a burster well that goes down the center of the shell. Filler of either sulfur mustard or white phosphorus is placed in the empty space and a fuze is fixed to the top before firing. ...

155mm Artillery Shells
155 mm (6.1 in) is a common, NATO-standard, artillery caliber. It is defined in AOP-29 part 1 with reference to STANAG 4425. It is commonly used in field guns, howitzers, and gun-howitzers. Land warfare The caliber originated in France after its defeat in the Franco-Prussian War of 1870–1871, when an artillery committee met on 2 February 1874 to discuss new models for the French fortress and siege artillery, among which there was a piece in the caliber range (later on it became known as the De Bange 155 mm cannon). After several meetings, on 16 April 1874 the committee settled on the 15.5 cm caliber (in the subsequent program-letter of the committee, dating from 21 April 1874, the caliber was for the first time expressed as 155 mm). Since the early 21st century, most NATO armies have adopted 155 mm weapons as an all-purpose standard. They are seen as striking a good compromise between range and power, while only using a single caliber greatly simplifies the logis ...

M121 155 Mm Projectile
The M121/A1 155mm Projectile was a chemical artillery shell designed for use by the U.S. Army. It was designed to be used with approximately of GB or VX nerve agents. History The U.S. Army standardized the M121 shell in 1954 as an artillery shell capable of delivering sarin via a 155mm howitzer.Smart, Jeffery K. Medical Aspects of Chemical and Biological Warfare'': Chapter 2 - History of Chemical and Biological Warfare: An American Perspective,PDF p. 51), '' Borden Institute'', Textbooks of Military Medicine, PDF via Maxwell-Gunter Air Force Base, accessed November 13, 2008. Shortly after the discovery of VX in 1952, the U.S. Army Chemical Corps began experimenting with employment systems for the newly discovered nerve agent. The M121A1 was standardized in 1961 as a modified version of the original projectile with the additional capability of transporting VX as well as sarin. The M121 and M121A1 have never been used in combat and remaining stockpiles are currently being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M110 155 Mm Projectile
The M110 155mm Projectile is an artillery shell used by the U.S. Army and U.S. Marine Corps. The M110 was originally designed as a chemical artillery round to deliver blister agents via howitzer as a replacement for the World War I-era 75mm chemical projectiles. The design was later repurposed as a white phosphorus smoke round for marking, signaling, and screening purposes. The white phosphorus variants of the shell also have a secondary, incendiary effect. Original design Officially designated Projectile, 155mm howitzer, M110, the original round was a 26.8-inch (68.1 cm), steel shell with a rotating band near its base and a burster rod down its center. The original shell typically contained of Sulfur mustard (H) or distilled sulfur mustard (HD), which would fill the hollow space in the shell. As early as the 1960s, a white phosphorus version was created under the same designation with of white phosphorus filler. Both versions were designed for employment by the M114 ...

Methylphosphonyl Difluoride
Methylphosphonyl difluoride (DF), also known as EA-1251 or difluoro, is a chemical weapon precursor. Its chemical formula is CH3POF2. It is a List of Schedule 1 substances (CWC), Schedule 1 substance under the Chemical Weapons Convention. It is used for production of sarin and soman as a component of binary chemical weapons; an example is the M687 artillery shell, where it is used together with a mixture of isopropyl alcohol and isopropylamine, isopropyl amine, producing sarin. Preparation Methylphosphonyl difluoride can be prepared by reacting Methyl phosphonic dichloride, methylphosphonyl dichloride with hydrogen fluoride (HF) or sodium fluoride (NaF). Safety Methylphosphonyl difluoride is both reactive and corrosive. It is absorbed through skin and causes burns and mild nerve agent symptoms. It reacts with water, producing HF fumes and methylphosphonic acid as a result. It is also capable of corroding glass. Significance in international relations In 2013–2014, the stock ...

Shell (projectile)
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape ...
