M687 155mm Projectile
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 t ...

Isopropanol
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural resins. Notably, it is not miscible with salt solutions and can be separated by adding sodium chloride in a process known as salting out. It forms an azeotrope with water, resulting in a boiling point of 80.37 °C and is characterized by its slightly bitter taste. Isopropyl alcohol becomes viscous at lower temperatures, freezing at −89.5 °C, and has significant ultraviolet-visible absorbance at 205 nm. Chemically, it can be oxidized to acetone or undergo various reactions to form compounds like isopropoxides or aluminium isopropoxide. As an isopropyl group linked ...

M55 (rocket)
The M55 rocket was a chemical weapon developed by the United States in the 1950s. The United States Army produced both Sarin and VX unitary warheads for the M55. History In 1951, the US Army Chemical Corps and United States Army Ordnance Corps, Ordnance Corps initiated a joint program to develop a 115mm chemical rocket. The US Army Ordnance Corps designed the 115mm T238 and launcher in 1957 to provide the army a means to attack large area targets with chemical agents. Artillery and mortars are for small area targets; and due to different spin stabilities, warheads intended for explosives are not ideal for chemical delivery. The 115mm rocket was subsequently accepted as the M55 rocket with M91 launcher. Produced from 1959 to 1965, the M55s were manufactured at Newport Army Ammunition Plant and tested at Aberdeen Proving Ground. The Army produced unitary warheads filled with Sarin (GB) and VX (nerve agent), VX nerve agents for the M55.Croddy, Eric and Wirtz, James J. ''Weapons of Ma ...

M2 4
M, or m, is the thirteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of several western European languages and others worldwide. Its name in English is ''em'' (pronounced ), plural ''ems''. History The letter M is derived from the Phoenician Mem via the Greek Mu (Μ, μ). Semitic Mem is most likely derived from a " Proto-Sinaitic" (Bronze Age) adoption of the "water" ideogram in Egyptian writing. The Egyptian sign had the acrophonic value , from the Egyptian word for "water", ''nt''; the adoption as the Semitic letter for was presumably also on acrophonic grounds, from the Semitic word for "water", '' *mā(y)-''. Use in writing systems English In English, represents the voiced bilabial nasal . The Oxford English Dictionary (first edition) says that is sometimes a vowel, such as in words like ''spasm'' and in the suffix ''-ism''. In modern terminology, this is described as a syllabic consonant (IPA: ). M is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M121 155 Mm Projectile
The M121/A1 155 mm 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 155 mm 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 di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M110 155 Mm Projectile
The M110 155 mm 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 75 mm 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, 155 mm 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 M ...

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. Va ...

Chemical Weapons Convention
The Chemical Weapons Convention (CWC), officially the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, is an arms control treaty administered by the Organisation for the Prohibition of Chemical Weapons (OPCW), an intergovernmental organization based in The Hague, Netherlands. The treaty entered into force on 29 April 1997. It prohibits the use of chemical weapons, and the large-scale development, production, stockpiling, or transfer of chemical weapons or their precursors, except for very limited purposes (research, medical, pharmaceutical or protective). The main obligation of member states under the convention is to effect this prohibition, as well as the destruction of all current chemical weapons. All destruction activities must take place under OPCW verification. 193 states have become parties to the CWC and accept its obligations. Israel has signed but not ratified the agreement, while three o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates its function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the deton ...

Hydrogen Fluoride
Hydrogen fluoride (fluorane) is an Inorganic chemistry, inorganic compound with chemical formula . It is a very poisonous, colorless gas or liquid that dissolves in water to yield hydrofluoric acid. It is the principal industrial source of fluorine, often in the form of hydrofluoric acid, and is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers such as polytetrafluoroethylene (PTFE). HF is also widely used in the petrochemical industry as a component of superacids. Due to strong and extensive hydrogen bonding, it boils near room temperature, a much higher temperature than other hydrogen halides. Hydrogen fluoride is an extremely dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas. History In 1771 Carl Wilhelm Scheele prepared the aqueous solution, hydrofluoric acid in large quantities, although hydrofluoric acid ...
