TOW Under Armor
The BGM-71 TOW ("Tube-launched, Optically tracked, Wire-guided", pronounced ) is an American anti-tank missile. TOW replaced much smaller missiles like the SS.10 and ENTAC, offering roughly twice the effective range, a more powerful warhead, and a greatly improved semi-automatic command to line of sight (SACLOS) that could also be equipped with infrared cameras for night time use. First produced in 1968, TOW is one of the most widely used anti-tank guided missiles. It can be found in a wide variety of manually carried and vehicle-mounted forms, as well as widespread use on helicopters. Originally designed by Hughes Aircraft in the 1960s, the weapon is currently produced by RTX. History Previous designs Late in World War II, the German Army began experimenting with modified versions of the Ruhrstahl X-4 wire-guided missile. Originally developed for the ''Luftwaffe'' as an anti-bomber weapon, by changing the warhead to one using a high-explosive anti-tank (HEAT) design, the n ...

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 must 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ENTAC
ENTAC ("Engin Téléguidé Anti-Char") or MGM-32A was a French MCLOS Wire-guided missile, wire-guided anti-tank missile. Developed in the early 1950s, the weapon entered service with the French Army in 1957. Production ended in 1974 after approximately 140,000 had been built. Development The missile was developed by the French Government agency - DTAT (''Direction Technique des Armements Terrestres'') at the same time as the private industry SS.10. Development time for the ENTAC was longer than the SS.10, so it did not enter service until 1957. It proved to be a great improvement over the SS.10, which had entered production five years earlier. Once fully developed and tested, production of the ENTAC was given to the firm of Aerospatiale. The ENTAC was designed to be a man-portable weapon or operated from a small vehicle like the Jeep, replacing the Nord SS.10 in French service. Design The missile is launched from a simple metal box, which is connected to an operator station. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a missile guidance, guided missile primarily designed to hit and destroy armoured fighting vehicle, heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank warfare, anti-tank weapons, like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote Wire-guided missile, wire guidan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire-guided Missile
A wire-guided missile is a missile that is guided by signals sent to it via thin wires connected between the missile and its guidance mechanism, which is located somewhere near the launch site. As the missile flies, the wires are reeled out behind it ( command guidance). This guidance system is most commonly used in anti-tank missiles, where its ability to be used in areas of limited line-of-sight make it useful, while the range limit imposed by the length of the wire is not a serious concern. The longest range wire-guided missiles in current use are limited to about . History Electrical wire guidance dates back to the early 20th century with an early example being the Lay Torpedo. A prototype ground-based electrical wire-guided torpedo was built by the Germans during World War II. The pair of deployed German guided air-delivered ordnance designs, the Fritz X and Henschel Hs 293, both used the ''Kehl-Strassburg'' radio guidance system for control. However, because the ...

Radio Guidance
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely operate a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of model vehicles from a hand-held radio transmitter. Industrial, military, and scientific research organizations make use of radio-controlled vehicles as well. A rapidly growing application is control of unmanned aerial vehicles (UAVs or drones) for both civilian and military uses, although these have more sophisticated control systems than traditional applications. History The idea of controlling unmanned vehicles (for the most part in an attempt to improve the accuracy of torpedoes for military purposes) predates the invention of radio. The latter half of the 1800s saw development of many such devices, connected to an operator by wires, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless
Wireless communication (or just wireless, when the context allows) is the transfer of information (''telecommunication'') between two or more points without the use of an electrical conductor, optical fiber or other continuous guided transmission medium, medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for NASA Deep Space Network, deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, Mobile phone, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include Global Positioning System, GPS units, garage door openers, wireless Mouse (computing), computer mouse, Keyboard (computing), keyboards and Headset (audio), headsets, headphones, radio receivers, satelli ...

Rolled Homogeneous Armor
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protective ...

Hughes Aircraft Company
The Hughes Aircraft Company was a major American aerospace and defense contractor founded on February 14, 1934 by Howard Hughes in Glendale, California, as a division of the Hughes Tool Company. The company produced the Hughes H-4 Hercules aircraft, the atmospheric entry probe carried by the ''Galileo'' spacecraft, and the AIM-4 Falcon guided missile. Hughes Aircraft was founded to build Hughes' H-1 Racer world speed record aircraft, and later modified other aircraft for his transcontinental and global circumnavigation speed record flights. The company relocated to Culver City, California, in 1940 and began manufacturing aircraft parts as a subcontractor. Hughes attempted to mold it into a major military aircraft manufacturer during World War II. However, its early military projects ended in failure, with millions of dollars in U.S. government funds expended for only a handful of prototypes, resulting in a highly publicized U.S. Senate investigation into alleged mismanage ...
