SA-19 Grisom
The 2K22 Tunguska () is a Soviet tracked self-propelled anti-aircraft gun armed with a surface-to-air gun and missile system. It is designed to provide day and night protection for infantry and tank regiments against low-flying aircraft, helicopters, and cruise missiles in all weather conditions. The NATO reporting name for the missile used by the weapon system is SA-19 "Grison". Development Development of the 2K22 anti-aircraft system began on 8 June 1970. At the request of the Soviet Ministry of Defense, the KBP Instrument Design Bureau in Tula, under the guidance of the appointed Chief Designer , started work on a 30mm anti-aircraft system as a replacement for the 23mm ZSU-23-4. The project, code-named " Tunguska", was undertaken to improve on the observed shortcomings of the ZSU-23-4 (short range and no early warning) and a counter to new ground attack aircraft in development, such as the A-10 Thunderbolt II and the AH-64 Apache, which were designed to be highly resistant t ...

NATO Reporting Name
NATO uses a system of code names, called reporting names, to denote military aircraft and other equipment used by post-Soviet states, former Warsaw Pact countries, China, and other countries. The system assists military communications by providing short, one- or two-syllable names, as alternatives to the precise proper names, which may be easily confused under operational conditions or are unknown in the Western world. The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as the Air Standardization Coordinating Committee (ASCC), which is separate from NATO. Based in Washington DC, AFIC comprises representatives from the militaries of three NATO members (Canada, the United Kingdom and United States) and two non-NATO countries (Australia and New Zealand). When the system was introduced in the 1950s, reporting names also implicitly designated potentially hostile aircraft. However, since the end of the Cold War, ...

AH-64 Apache
The Hughes/McDonnell Douglas/Boeing AH-64 Apache ( ) is an American twin-turboshaft attack helicopter with a tailwheel-type landing gear and a tandem cockpit for a crew of two. Nose-mounted sensors help acquire targets and provide night vision. It carries a M230 chain gun under its forward fuselage and four hardpoints on stub-wing pylons for armament and stores, typically AGM-114 Hellfire missiles and Hydra 70 rocket pods. Redundant systems help it survive combat damage. The Apache began as the ''Model 77'' developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. The prototype YAH-64 first flew on 30 September 1975. The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After acquiring Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and development. The helicopter was introduced to U.S. Army service in April 1986. The advan ...

IR Beacon
A beacon is an intentionally conspicuous device designed to attract attention to a Geodetic datum, specific location. A common example is the lighthouse, which draws attention to a fixed point that can be used to navigate around obstacles or into port. More modern examples include a variety of radio beacons that can be read on radio direction finders in all weather, and Transponder, radar transponders that appear on radar displays. Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its aerodrome beacon, airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of Telegraph#Optical telegraph, optical telegraphy. For navigation Beacons help guide navigation, navigators to their destinations. Types of navigational beacons include rada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countermeasure
A countermeasure is a measure or action taken to counter or offset another one. As a general concept, it implies precision and is any technological or tactical solution or system designed to prevent an undesirable outcome in the process. The first known use of the term according to the Merriam-Webster dictionary was in 1923. Countermeasures can refer to the following disciplinary spectrum: * Medicine * Materials engineering * Electro-magnetic engineering * Policing * Information technology * International Law * Diplomatic security * Pollution prevention * Aviation Defense countermeasures are often divided into "active" and "passive". Active "Active" countermeasures mean the system user or the defender takes an active position because the incoming incident is known so the system takes active approaches to deal with such possible damage. Such an approach may include setting up a security method for the incident or actively trying to stop or intersect such damage. Passive "Pass ...

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries 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 e ...

Proximity Fuze
A Proximity Fuse (also VT fuse or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces. This sophisticated trigger mechanism may increase lethality by 5 to 10 times compared to the common contact fuse or timed fuse. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch, or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching the target or after passing it. At the start of the Bl ...

Cruise Missile
A cruise missile is an unmanned self-propelled guided missile that sustains flight through aerodynamic lift for most of its flight path. Cruise missiles are designed to deliver a large payload over long distances with high precision. Modern cruise missiles are capable of traveling at high Aerodynamics#Incompressible aerodynamics, subsonic, Supersonic speed, supersonic, or Hypersonic speed, hypersonic speeds, are self-navigating, and are able to fly on a non-Ballistics, ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the Americans, American Aircraft pilot, aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and barometric altitude control. Inspired by the experiments, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocannon
An autocannon, automatic cannon or machine cannon is a automatic firearm, fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary ammunition, incendiary shell (projectile), shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal ballistics, terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns, or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single gun barrel, barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or "rotary cannon". If it uses a single barrel with a rotating cylinder with multiple chambers, it is known as a "revolver autocannon" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yom Kippur War
The Yom Kippur War, also known as the Ramadan War, the October War, the 1973 Arab–Israeli War, or the Fourth Arab–Israeli War, was fought from 6 to 25 October 1973 between Israel and a coalition of Arab world, Arab states led by Egypt and Syria. Most of the fighting occurred in the Sinai Peninsula and Golan Heights, territories Israeli-occupied territories, occupied by Israel in 1967. Some combat also took place in mainland Geography of Egypt, Egypt and Northern District (Israel), northern Israel. Egypt aimed to secure a foothold on the eastern bank of the Suez Canal and use it to negotiate the return of the Israeli occupation of the Sinai Peninsula, Sinai Peninsula. The war started on 6 October 1973, when the Arab coalition launched a surprise attack across their respective frontiers during the Jewish holy day of Yom Kippur, which coincided with the 10th day of Ramadan. The United States and Soviet Union engaged in massive resupply efforts for their allies (Israel and the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LOMO
LOMO () is a manufacturer of medical and motion-picture lenses and equipment based in St. Petersburg, Russia. The company was awarded three Order of Lenin decorations by the Soviet Union. Its Lomo LC-A consumer camera was the inspiration for the lomography photographic movement. History The company was founded in 1914 in Petrograd (now Saint Petersburg). It was established as a French – Russian limited company to produce lenses and cameras. It manufactured gun sights during World War I. In 1919, it was nationalised. In 1921, the factory was named the Factory of State Optics, G.O.Z. In 1925, camera production was resumed, and several lens designs tested between 1925 and 1929. Further reorganisations of the Soviet optical factories in several stages finally resulted in that the factory at Leningrad became GOMZ, the Russian Optical and Mechanical Factory. In the transition period 1932 to 1935 a copy of the Leica camera was developed, the VOOMP I. Today LOMO makes military ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
