Pueblo Chemical Agent-Destruction Pilot Plant
The Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) is a chemical weapons destruction facility built to destroy the chemical weapons stockpile formerly stored at the U.S. Army Pueblo Chemical Depot (PCD), now known as the U.S. Army Chemical Materials Activity-West, in southeastern Colorado. The stockpile originally contained 2,613 U.S. tons of mustard agent in 155 mm projectiles, 105 mm projectiles, and 4.2-inch mortar rounds. The weapons had been stored at the 23,000-acre (93-km²) depot since the 1950s. On June 16, 2023, the main plant at PCAPP destroyed its last munition, a 4.2-inch mortar round. On June 22, 2023, the last munition in the stockpile of chemical weapons in Colorado, an overpacked 155 mm projectile containing mustard agent, was destroyed using a Static Detonation Chamber. The last munition in the declared U.S. stockpile was destroyed in July 2023 in Kentucky. PCAPP used neutralization followed by biotreatment to destroy the majority of the stock ...

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 ...

Military Installations In Colorado
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstr ...

Chemical Weapons Destruction Facilities
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure. Chemical substances can exist in several different physical states or phases (e.g. solids, liquids, gases, or plasma) without changing their chemical composition. Substances transition between these phases of matter in response to changes in temperature or pressure. Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Pueblo County, Colorado
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Realignment And Closure
Base Realignment and Closure (BRAC) was a process by a Federal government of the United States, United States federal government commission to increase the efficiency of the United States Department of Defense by coordinating the realignment and closure of List of American military installations, military installations following the end of the Cold War. Over 350 installations have been closed in five BRAC rounds: 1988, 1991, 1993, 1995, and 2005. These five BRAC rounds constitute a combined savings of $12 billion annually. Background The Federal Property and Administrative Services Act of 1949, passed after the 1947 reorganization of the National Military Establishment, reduced the number of U.S. military bases, forts, posts, and stations. The subsequent 1950s buildup for the Cold War (e.g., during the Korean War) resulted in large numbers of new installations, such as the Permanent System radar stations and Semi-Automatic Ground Environment (SAGE) NORAD Control Center, control ce ...

Blue Grass Chemical Agent-Destruction Pilot Plant
The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is a facility built to destroy the chemical weapons stockpile at the Blue Grass Army Depot (BGAD), near Richmond, Kentucky. The last munition, an M55 rocket containing GB nerve agent, was destroyed July 7, 2023. It marked the last chemical weapon in the U.S. stockpile. Since 1944, the Army stored 523 short tons (474 t) of nerve agents sarin (GB) and VX and mustard agent in 155mm projectiles, 8-inch projectiles and M55 rockets at BGAD. That was about 2% of the nation's original chemical weapons stockpile. BGCAPP used neutralization to destroy the majority of the stockpile and Static Detonation Chamber units to augment the main plant. Destruction of this stockpile was a requirement of the Chemical Weapons Convention, an international treaty to which the United States is a party. The Organisation for the Prohibition of Chemical Weapons is the implementing body of the Chemical Weapons Convention and monitored the prog ...

Pueblo Depot Activity
Pueblo Depot Activity ''(PUDA)'', formerly known as the Pueblo Ordnance Depot and the Pueblo Army Depot, was a U.S. Army ammunition storage and supply facility. Responsibility for the depot fell upon the United States Army Ordnance Corps, and the first civilians were hired in 1942 as operations began. The mission quickly expanded to include general supplies as well. It is a site located east of Pueblo, Colorado at . In 1945 they began to receive mass amounts of equipment returning from the combat theaters of World War II. Therefore, the mission expanded yet again to include the maintenance and refurbishing of artillery, fire control, and optical material. In 1951 the depot assumed responsibility to distribute U.S. Air Force ammunition for an eight-state area, as well as storage of strategic and critical materials for the General Services Administration (GSA). They were also tasked to rebuild and provide on-site maintenance support for guided missiles, ensure calibration and mainte ...

National Environmental Policy Act
The National Environmental Policy Act (NEPA) is a United States environmental law designed to promote the enhancement of the environment. It created new laws requiring U.S. federal government agencies to evaluate the environmental impacts of their actions and decisions, and it established the President's Council on Environmental Quality (CEQ). The Act was passed by the U.S. Congress in December 1969 and signed into law by President Richard Nixon on January 1, 1970.United States. National Environmental Policy Act of 1969. , Approved January 1, 1970. ''et seq.'' More than 100 nations around the world have enacted national environmental policies modeled after NEPA. NEPA requires Federal agencies to evaluate the environmental effects of their actions. NEPA's most significant outcome was the requirement that all executive Federal agencies prepare environmental assessments (EAs) and environmental impact statements (EISs). These reports state the potential environmental effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflagration
Deflagration (Lat: ''de + flagrare'', 'to burn down') is subsonic combustion in which a pre-mixed flame propagates through an explosive or a mixture of fuel and oxidizer. Deflagrations in high and low explosives or fuel–oxidizer mixtures may transition to a detonation depending upon confinement and other factors. Most fires found in daily life are diffusion flames. Deflagrations with flame speeds in the range of 1 m/s differ from detonations which propagate supersonically with detonation velocities in the range of km/s. Applications Deflagrations are often used in engineering applications when the force of the expanding gas is used to move an object such as a projectile down a barrel, or a piston in an internal combustion engine. Deflagration systems and products can also be used in mining, demolition and stone quarrying via gas pressure blasting as a beneficial alternative to high explosives.

Shaped Charge
A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped 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 depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym ''HEAT'' (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature—however the process creates significant heat and often has a significant secondary incendiary ef ...

Detonation
Detonation () is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds about 1 km/sec and differ from deflagrations which have subsonic flame speeds about 1 m/sec. Detonation may form from an explosion of fuel-oxidizer mixture. Compared with deflagration, detonation doesn't need to have an external oxidizer. Oxidizers and fuel mix when deflagration occurs. Detonation is more destructive than deflagrations. In detonation, the flame front travels through the air-fuel faster than sound; while in deflagration, the flame front travels through the air-fuel slower than sound. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. TNT, dynamite, and C4 are examples of high power explosives that detonate. The detonation velocity, velocity of detonation in solid an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
