Man-portable Air-defense System
Man-portable air-defense systems (MANPADS or MPADS) are portable surface-to-air missiles. They are guided weapons and are a threat to low-flying aircraft, especially helicopters. Overview MANPADS were developed in the 1950s to provide military ground forces with protection from jet aircraft. They have received a great deal of attention, partly because armed groups have used them against commercial airliners. These missiles, affordable and widely available through a variety of sources, have been used successfully over the past three decades both in military conflicts, as well as by terrorist organizations. Twenty-five countries, including the United Kingdom, the United States, Poland, Sweden, Russia, and Turkey, produce man-portable air defense systems.CRS RL31741 page 1 Possession, export, and trafficking of such weapons is officially tightly controlled, due to the threat they pose to civil aviation, although such efforts have not always been successful. The missiles are about ...

Sa-7
The 9K32 Strela-2 (russian: Cтрела, "arrow"; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile (or MANPADS) system. It is designed to target aircraft at low altitudes with passive infrared homing guidance and destroy them with a high explosive warhead. Broadly comparable in performance with the US Army FIM-43 Redeye, the Strela-2 was the first Soviet man-portable SAM – full-scale production began in 1970. While the Redeye and 9K32 Strela-2 were similar, the missiles were not identical. The Strela-2 was a staple of the Cold War and was produced in huge numbers for the Soviet Union and their allies, as well as revolutionary movements. Though since surpassed by more modern systems, the Strela and its variants remain in service in many countries, and have seen widespread use in nearly every regional conflict since 1972. Development The end of World War II led to a major shift in Soviet defence policy. The advent of long range, hig ...

Jet Engine
A jet engine is a type of reaction engine discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition can include rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet engine, pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypass turbofan engines. They give higher speed and greater fuel eff ...

Soviet–Afghan War
The Soviet–Afghan War was a protracted armed conflict fought in the Democratic Republic of Afghanistan from 1979 to 1989. It saw extensive fighting between the Soviet Union and the Afghan mujahideen (alongside smaller groups of anti-Soviet Maoism, Maoists) after the former militarily intervened in, or launched an invasion of, Afghanistan to support the local pro-Soviet government that had been installed during Operation Storm-333. Most combat operations against the mujahideen took place in the Afghan countryside, as the country's urbanized areas were entirely under Soviet control. While the mujahideen were backed by various countries and organizations, the majority of their support came from Pakistan, Saudi Arabia, the United States, the United Kingdom, China, and Iran; the American pro-mujahideen stance coincided with a sharp increase in bilateral hostilities with the Soviets during the Cold War (1979–1985), Cold War. The conflict led to the deaths of between 562,000 and ...

Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ...

Staring Array
A staring array, also known as staring-plane array or focal-plane array (FPA), is an image sensor consisting of an array (typically rectangular) of light-sensing pixels at the focal plane of a lens. FPAs are used most commonly for imaging purposes (e.g. taking pictures or video imagery), but can also be used for non-imaging purposes such as spectrometry, LIDAR, and wave-front sensing. In radio astronomy, the FPA is at the focus of a radio telescope. At optical and infrared wavelengths, it can refer to a variety of imaging device types, but in common usage it refers to two-dimensional devices that are sensitive in the infrared spectrum. Devices sensitive in other spectra are usually referred to by other terms, such as CCD (charge-coupled device) and CMOS image sensor in the visible spectrum. FPAs operate by detecting photons at particular wavelengths and then generating an electrical charge, voltage, or resistance in relation to the number of photons detected at each pixel. This ...

Type 91 Surface-to-air Missile
The is a Japanese man-portable air-defense system (MANPADS). Its appearance is similar to the US-made FIM-92 Stinger anti-aircraft missile. It was created in order to replace its stock of American-made Stinger MANPADS, since the Type 91 has a better guidance system, which consist of both visible light and infrared system options. The Stinger, on the other hand, uses a passive infrared homing guidance system. In the ranks of the JSDF, the Type 91 is colloquially known as Hand Arrow. The Type 91 is sometimes mistaken as a Japanese-made version of the Stinger. The Type 91 is currently exclusively used by the JSDF and has not been exported overseas to date due to previous interpretations of post-war constitutional restrictions and the laws arising from them. The Type 91 is officially treated as a 4th-generation MANPAD system. History Development work on an advanced infra-red seeker began in 1979 at the Technical Research and Development Institute (TRDI) after Toshiba and Kawasak ...

SA-25
The 9K333 ''Verba'' (russian: Верба, "Willow") is a Russian fourth-generation man-portable infrared homing surface-to-air missile (SAM) MANPADS. "9K333" is the Russian GRAU designation of the system. Its NATO reporting name is SA-25. History The 9K333 ''Verba'' was originally developed as a replacement for the 9K38 Igla. The Verba's primary new feature is its multispectral optical seeker, using three sensors - ultraviolet, near infrared, and mid-infrared - as opposed to the Igla-S' two. Cross-checking sensors against one another better discriminates between relevant targets and decoys, and decreases the chance of disruption from countermeasures, including lasers that attempt to blind missiles. According to a KBM spokesperson, the Verba can engage fixed- and rotary-wing aircraft and “new types of threats” such as unmanned aerial vehicles and cruise missiles. “The 9K333 can effectively engage aerial targets with low infrared signature. The system can be coupled to an exte ...

Ultraviolet
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nanometer, nm (with a corresponding frequency around 30 Hertz, PHz) to 400 nm (750 Hertz, THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionization, ionize atoms, it can cause chemical reactions and causes many substances to glow or fluorescence, fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surf ...

Rosette Seeker
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares beh ...

Mistral Missile
The Missile Transportable Anti-aérien Léger (English: Transportable lightweight anti-air missile), commonly called Mistral, is a French infrared homing short range air defense system manufactured by MBDA France (formerly by Matra Defence and then Matra BAe Dynamics). Based on the French SATCP (''Sol-Air à Très Courte Portée''), the portable missile later to become the Mistral began development in 1974. It was initially deployed in 1988 for the first version (S1), 1997 for the second version (M2), and 2019 for the third version (M3). Description Mistral is a short-range air defence (SHORAD) missile system that can be used from vehicles, surface ships, and helicopters, as well as in a portable configuration. When used in the MANPADS role the "Mistral" missile is transported in a transport and launch container (MPC) together with "friend or foe" interrogator, power source and tripod with its sighting devices.
