Boeing Laser Avenger
Boeing Laser Avenger is an infrared laser system (with power levels somewhere in the tens of kilowatts range) mounted on an AN/TWQ-1 Avenger combat vehicle developed by Boeing Combat Systems in Huntsville, Alabama. Laser Avenger integrates a directed energy weapon together with the kinetic weapons of the Avenger air defense system. History Jan 2009 - "If funded by the Pentagon, the Laser Avenger could be available within a year," said Boeing spokesman Marc Selinger. Boeing has so far funded the project itself. Dec 2008 - Testing at White Sands Missile Range, N.M., Laser Avenger succeeded in its principal test objectives by targeting and tracking 3 small UAVs (flying against the complex backdrop of mountains and desert). It also shot down one of the UAVs from an operationally relevant range. This marks the first time a combat vehicle has used a laser to shoot down a UAV. As part of the overall counter-UAV demonstration, Boeing also successfully test-fired a lightweight 25mm machine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

AN/TWQ-1 Avenger
The Avenger Air Defense System, designated AN/TWQ-1 under the Joint Electronics Type Designation System, is an American self-propelled surface-to-air missile system which provides mobile, short-range air defense protection for ground units against cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters. The Avenger was originally developed for the United States Armed Forces and is currently used by the U.S. Army. The Avenger system was also used by the U.S. Marine Corps. History Originally developed as a private venture by Boeing in the 1980s, the Avenger was developed over a period of only 10 months from initial concept to delivery for testing to the U.S. Army. Initial testing was conducted in May 1984 at the Army's Yakima Training Center in the U.S. state of Washington. During testing three FIM-92 Stinger missiles were fired. During the first test firing the system achieved a direct hit while moving at . The second test firing, conducted at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huntsville, Alabama
Huntsville is a city in Madison County, Limestone County, and Morgan County, Alabama, United States. It is the county seat of Madison County. Located in the Appalachian region of northern Alabama, Huntsville is the most populous city in the state. Huntsville was founded within the Mississippi Territory in 1805 and became an incorporated town in 1811. When Alabama was admitted as a state in 1819, Huntsville was designated for a year as the first capital, before that was moved to more central settlements. The city developed across nearby hills north of the Tennessee River, adding textile mills in the late nineteenth century. Its major growth has taken place since World War II. During the war, the Army established Redstone Arsenal near here with a chemical weapons plant, and nearby related facilities. After the war, additional research was conducted at Redstone Arsenal on rockets, followed by adaptations for space exploration. NASA's Marshall Space Flight Center, the Unit ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Defense System
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3. This was the only ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missile Defense
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles. China, France, India, Iran, Israel, Italy, Russia, Taiwan, the United Kingdom and the United States have all developed such air defense systems. Missile defense categories Missile defense can be divided into categories based on various characteristics: type/range of missile intercepted, the trajectory phase where the intercept occurs, and whether intercepted inside or outside the Earth's atmosphere: Type/range of missile intercepted These types/ranges include strategic, theater and tactical. Each entails unique requirements for intercept, and a defensive system capable of intercepting one missile type frequently cannot intercept others. H ...

Redstone Arsenal
Redstone Arsenal (RSA) is a United States Army post and a census-designated place (CDP) adjacent to Huntsville in Madison County, Alabama, United States and is part of the Huntsville-Decatur Combined Statistical Area. The Arsenal is a garrison for various tenants across the Department of Defense, Department of Justice, and NASA. RSA has benefited from decisions by the Defense Base Realignment and Closure Commission. The Redstone Arsenal CDP had a residential population of 837 as of the 2020 census. The base contains a government and contractor workforce that averages 36,000 to 40,000 personnel daily. Established during World War II as a chemical manufacturing facility, in the immediate post-war era the Arsenal was used for research and development by German weapons rocket scientists who were brought to the U.S. as part of Operation Paperclip. The team first worked on ballistic missiles, starting with V-2 rocket derivatives, before moving on to a series of ever larger designs. Man ...
