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] |
Artillery Shell
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 shap ...

Chemical Weapon Delivery Systems
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, g ...

M687 155 Mm 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 th ...

M110 155mm 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 ...

M104 155mm 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. Var ...

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, The Netherlands. The treaty entered into force on 29 April 1997, and prohibits the large-scale use, development, production, stockpiling and transfer of chemical weapons and 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. As of August 2022, 193 states have become parties to the CWC and accept its obligations. Israel has signed but not ratified the agreement, while three other U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Corps
The Chemical Corps is the branch of the United States Army tasked with defending against chemical, biological, radiological, and nuclear (CBRN) weapons. The Chemical Warfare Service was established on 28 June 1918, combining activities that until then had been dispersed among five separate agencies of the United States federal government. It was made a permanent branch of the Regular Army by the National Defense Act of 1920. In 1945, it was redesignated the Chemical Corps. History Origins Discussion of the topic dates back to the American Civil War. A letter to the War Department dated 5 April 1862 from New York City resident John Doughty proposed the use of chlorine shells to drive the Confederate Army from its positions. Doughty included a detailed drawing of the shell with his letter. It is unknown how the military reacted to Doughty's proposal but the letter was unnoticed in a pile of old official documents until modern times. Another American, Forrest Shepherd, also propos ...

Borden Institute
The Borden Institute is a U.S. Army “Center of Excellence in Military Medical Research and Education”. In 1987, U.S. Army Colonel Russ Zajtchuk conceived the idea for a “Center of Excellence in Military Medical Research and Education,” under the Army's Office of The Surgeon General (OTSG). The center was soon made a reality, largely through the efforts of Zajtchuk, Dr. Don Jenkins, and Colonel Ron Bellamy. In 1992, to honor Lieutenant Colonel William Cline Borden (Major Walter Reed’s personal physician and conceiver of the original Walter Reed General Hospital) the center’s name was changed to Borden Institute. The institute was located at Delano Hall on the campus of Walter Reed Army Medical Center (WRAMC), in Washington, DC. After WRAMC's closure, the institute moved to Fort Sam Houston. To date, the Borden Institute has published nearly 20 volumes of the ''Textbook of Military Medicine'' (TMM) series. These comprehensive reference books on the art and science of m ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
