Semi-automatic Command To Line Of Sight
Semi-automatic command to line of sight (SACLOS) is a method of missile command guidance. In SACLOS, the operator has to continually point a sighting device at the target while the missile is in flight. Electronics in the sighting device and/or the missile then guide it to the target. Many SACLOS weapons are based on an infrared seeker aligned with the operator's gunsight or sighting telescope. The seeker tracks the missile, either the hot exhaust from its rocket motor or flares attached to the missile airframe, and measures the angle between the missile and the centerline of the operator's sights. This signal is sent to the missile, often using thin metal wires or a radio link, which causes it to steer back toward the center of the line-of-sight. Common examples of these weapons include the BGM-71 TOW wire-guided anti-tank guided missile (ATGM) and the Rapier radio-command surface-to-air missile (SAM). Another class of SACLOS weapons is based on the beam riding principle. In thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visible Light
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and ...

Bat (guided Bomb)
The ASM-N-2 Bat was a United States Navy World War II radar-guided glide bomb which was used in combat beginning in April 1944. It was developed and overseen by a unit within the National Bureau of Standards (which unit later became a part of the Army Research Laboratory) with assistance from the Navy's Bureau of Ordnance, the Massachusetts Institute of Technology, and Bell Telephone Laboratories. It is considered to be the first fully automated guided missile used in combat. Background In January 1941 RCA proposed a new TV-guided anti-shipping weapon, called Dragon, for which an operator would use the TV image sent from the nose of the weapon and operate aerodynamic controls during the weapon's fall. The National Bureau of Standards (NBS) would provide the airframe for use with a standard bomb, and was the same guidable ordnance airframe design used for the earlier, abortive Project Pigeon weapons program. The Pelican was a June 1942 modification using semi-active radar h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HJ-8
The HJ-8 or Hongjian-8 and Baktar Shikan (Pakistani version) () is a second generation tube-launched, optically tracked, wire-guided anti-tank missile system which was originally deployed by China's People's Liberation Army since the late 1980s. Development In 1970, China's armored corps first proposed to develop a successor to HJ-73 and this was later approved, designated as the AFT-8 or HJ-8. The missile was jointly developed by Research Institute 203 and 282nd Factory, but the program was interrupted by political turmoil. The key designers were Wang Xingzhi (王兴治) and Zhao Jiazheng (赵家铮), who developed the missile. Development was not completed until the early 1980s, after the end of the Great Proletarian Cultural Revolution. After receiving state certification, the missile entered mass-production in 1984. HJ-8 is an optically tracked, wire guided ATGM. A series of upgraded variants have been developed since. HJ-8 and its variants are manufactured by NORINCO's Fac ...

Bumbar
The Bumbar ( sr-cyr, Бумбар, Bumbar, lit=Bumblebee) is a Serbian short-range portable anti-tank missile system. Description The Bumbar is a wire-guided, man-portable, short-ranged missile system for use against ground targets. The missile has a soft launch capability - the main motor firing after the missile has left the launcher, which allows for the missile to be fired from confined spaces, which is a necessity in urban warfare. During its flight, the rocket is maneuvered by unique system of thrust vectoring. The missile is propelled by two main rocket motor exhaust vanes located at mid body. As the missile rotates the launch units send signals commanding the correction by one of the two vanes to move against the missile motors thrust. For example, if the missile has to move to the left, the right thrust vector vane will actuate at the correct time. It is protected against electronic countermeasures through: "Use of CCD matrix sensors, fast image processing computer and ro ...

AT-7 Saxhorn
The 9K115 Metis (; NATO reporting name AT-7 Saxhorn) is a man-portable, tube launched, SACLOS wire-guided anti-tank guided missile of the Soviet Union. It is considered the Soviet counterpart to the American M47 Dragon ATGM. The relatively small 9K115 missile was generally underpowered compared to contemporary armored threats, and consequently it was little-exported and little used in combat. Development The missile was developed by the Tula KBP. It is very similar to the 9K111 Fagot in external appearance (having three main fins); however, the missile is much lighter—primarily because of the reduced fuel load, which reduces the maximum range to . During the 1980s, an upgraded version of the missile was developed—the ''Metis-M'' 9M131 (sometimes labelled ''Metis-2''). Fired from the same launcher, the new missile is much larger and heavier, with an increased range and a larger warhead. The NATO designation for this missile is AT-13 Saxhorn-2. History The missile was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M47 Dragon
The M47 Dragon, known as the FGM-77 during development, is an American shoulder-fired, man-portable anti-tank guided missile system. It was phased out of U.S. military service in 2001, in favor of the newer FGM-148 Javelin system. The M47 Dragon uses a wire-guidance system in concert with a high explosive anti-tank warhead and was capable of defeating armored vehicles, fortified bunkers, main battle tanks, and other hardened targets. While it was primarily created to defeat the Soviet Union's T-55, T-62, and T-72 tanks, it saw use well into the 1990s, seeing action in the Persian Gulf War. The U.S. military officially retired the weapon in 2001. The United States destroyed the last of its stocks of the missile in 2009. The weapon system remains in active service with other militaries around the world. History In 1959, the US Army Ordnance Missile Command suggested the development of a heavy medium range assault weapon. In 1960, the United States Army launched the MAW (Mediu ...

AT-5 Spandrel
The 9M113 ''Konkurs'' (russian: 9М113 «Конкурс»; en, "Contest"; NATO reporting name AT-5 ''Spandrel'') is a Soviet SACLOS wire-guided anti-tank missile. A development of the 9K111 Fagot with greater firepower, the 9M113 Konkurs can use the same launchers and is very similar visually, distinguishable only by a slight bulge towards the end of the Konkurs' missile tube. Development The 9M113 Konkurs was developed by the Tula Machinery Design Bureau (Tula KBP). Development began with the aim of producing the next generation of SACLOS anti-tank missiles, for use in both the man-portable role and the tank destroyer role. The 9M113 Konkurs was developed alongside the 9M111; the missiles use similar technology, differing only in size. The original 9M113 with a single-charge warhead can penetrate 600 mm of rolled homogeneous armor (RHA). The missile entered service in 1974. Iran bought a license for the Konkurs in 1991 and began producing a copy, the Tosan (not to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AT-4 Spigot
The 9K111 ''Fagot'' (russian: Фагот; "bassoon") is a second-generation tube-launched semi-automatic command to line of sight (SACLOS) wire-guided anti-tank missile system of the Soviet Union for use from ground or vehicle mounts. The 9K111 Fagot missile system was developed by the Tula KBP Design Bureau for Instrument Building. "9M111" is the GRAU designation of the missile. Its NATO reporting name is AT-4 Spigot. Development The 9K111 Fagot was developed by the Tula Machinery Design Bureau (Tula KBP) and development began in 1962 with the aim of producing the next generation of SACLOS anti-tank guided missile (ATGM) for use in two roles: as man portable and tank destroyer. The 9K111 Fagot was developed alongside the 9M113 Konkurs; both missiles use similar technology, differing in size only, and can use the same launchers. The missile entered service in 1970. History The anti-tank platoon of a Soviet BTR equipped motor rifle battalion had two (sometimes three) ATGM squads, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swingfire
Swingfire was a British wire-guided anti-tank missile developed in the 1960s and produced from 1966 until 1993. The name refers to its ability to make a rapid turn of up to ninety degrees after firing to bring it onto the line of the sighting mechanism. This means that the launcher vehicle could be concealed and the operator, using a portable sight, placed at a distance in a more advantageous firing position. Swingfire entered operational service in 1969 and underwent several major upgrades during its time in service. It was used on a number of vehicles including the FV438, FV102 and several truck mountings including the Land Rover. Concepts adapting it to helicopters, tanks and even hovercraft went nowhere. Swingfire remained in service on the FV102 Striker until 2005 when they were retired in favour of man-portable missiles. Development Earlier efforts The British Army was among the first to introduce a heavy anti-tank missile when they introduced the Malkara in 1958. The M ...

HOT (missile)
The HOT (French: ''Haut subsonique Optiquement Téléguidé Tiré d'un Tube'', or High Subsonic, Optical, Remote-Guided, Tube-Launched) is a second-generation long-range anti-tank missile system. It was originally developed to replace the older SS.11 wire guided missile in French and West German service. The design was a collaboration between the German firm Bölkow and the French firm Nord. Bölkow and Nord later merged into MBB and Aérospatiale respectively, both of which then formed Euromissile to design and produce the MILAN, Roland and HOT. This ultimately became part of MBDA. In comparison to the SS.11, HOT has longer range, flies faster, and is semi-automatically guided instead of manually. It has become one of the most successful missiles of its class, with tens of thousands of missiles produced, used by no fewer than a dozen countries worldwide, and validated in combat in several wars. The missile system is also commonly mounted on light and medium armored vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
