Stingray Light Tank
The Stingray, sometimes known as the Commando Stingray, is a light tank produced by Textron Marine & Land Systems division (formerly Cadillac Gage). It was specifically designed to use as many existing components of other American armored fighting vehicles as possible to keep costs down. The Stingray was a private venture project aimed at foreign countries. As of 2020, Textron has kept the Stingray name registered. It was exported for use by armed forces of Thailand, who remain the only user. History The Stingray was developed in the 1980s as a private venture by Cadillac Gage Textron. The first prototype was completed in 1985. In 1988, the Royal Thai Army pressed the Stingray in service with 106 tanks purchased. The contract was for $150 million. Cadillac Gage provided assistance in repairing some of them after they obtained reports of cracked hulls. In 1992, development of the Stingray II Started. Its production was complete in 1994 with marketing promoted to friendly co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobra Gold
Cobra Gold refers to multi-national Indo-Pacific military exercises held in Thailand. They are among the largest annual exercises of their kind. Overview Cobra Gold was first held in 1982 and has improved coordination between the armed forces of the United States and Thailand in both hostile military and humanitarian efforts. As of 2021, Cobra Gold has several different activities that highlight regional security and effective regional crisis responses. The first is the Combined Arms Live-Fire Exercise (CALFEX), in which live ammunition is aimed at predetermined targets as troops advance and close in on their target. A Command Post Exercise (CPX) is when military officers engage in computerized war games, disaster relief, or humanitarian missions over several days. An Amphibious Exercise (AMPHIBEX) combines ship-to-shore movement capabilities, with vertical envelopment between the Royal Thai Armed Forces and U.S. military, with allied forces dependent on operational developme ...

M47 Patton
The M47 Patton was an American main battle tank, a development of the M46 Patton mounting an updated turret, and was in turn further developed as the M48 Patton. It was the second American tank to be named after General George S. Patton, commander of the U.S. Third Army during World War II and one of the earliest American advocates of tanks in battle. The M47 was the U.S. Army's and United States Marine Corps, Marine Corps' primary tank, intended to replace the M26 Pershing and M46 Patton medium tanks.although the Ordnance Committee Minutes/OCM #33476 ceased utilizing the heavy, medium, and light tank designations on 7 November 1950; going to the "...Gun Tank designation") The M47 was widely used by U.S. Cold War allies, both SEATO and NATO countries, and was the only Patton series tank that never saw combat while in US service. Although the later M48 Patton, M48s and M60 Patton, M60s were similar in appearance, those were completely new tank designs. Many different M47 Patton m ...

Light Tanks Of The Cold War
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 particle ...

Tanque Argentino Mediano
The ''Tanque Argentino Mediano'' (TAM; English: ''Argentine Medium Tank'') is a medium tank in service with the Argentine Army. Lacking the experience and resources to design a tank, the Argentine Ministry of Defense contracted German company Thyssen-Henschel. The vehicle was developed by a German and Argentine team of engineers, and was based on the German Marder infantry fighting vehicle chassis. The TAM met the Argentine Army's requirement for a modern, lightweight and fast tank with a low silhouette and sufficient firepower to defeat contemporary armored threats. Development began in 1974 and resulted in the construction of three prototypes by early 1977 and full-scale production by 1979. Assembly took place at the local TAMSE plant, founded for the purpose by the Argentine government. Economic difficulties halted production in 1983, but manufacturing began anew in 1994 until the army's order of 200 tanks was fulfilled. The TAM series includes seven different variants, su ...

M8 Armored Gun System
The M8 Armored Gun System (AGS), sometimes known as the Buford, is an American light tank that was intended to replace the M551 Sheridan and TOW missile-armed Humvees in the 82nd Airborne Division and 2nd Armored Cavalry Regiment (2nd ACR) of the U.S. Army respectively. The M8 AGS began as a private venture of FMC Corporation, called the Close Combat Vehicle Light (CCVL), in 1983. The Army began the Armored Gun System program to develop a mobile gun platform that could be airdropped. By 1992, the AGS was one of the Army's top priority acquisition programs. The service selected FMC's CCVL over proposals from three other teams. The service sought to purchase 300 AGS systems to begin fielding in 1997. The Army canceled the M8 AGS program in 1996 over the objections of Congress and the Department of Defense, due to the service's budgetary constraints. The Sheridan was retired without a true successor. The AGS never saw service, though the 82nd Airborne sought to press a limited nu ...

Hughes Electronics
Hughes Electronics Corporation was formed in 1985 when Hughes Aircraft was sold by the Howard Hughes Medical Institute to General Motors for $5.2 billion. The surviving parts of Hughes Electronics are today known as The DirecTV Group. On June 5, 1985 General Motors was announced as the winner of a secretive five month, sealed-bid auction. Other bidders included Ford Motor Company and Boeing. The purchase was completed on December 20, 1985, for an estimated $5.2 billion, $2.7 billion in cash and the rest in 50 million shares of GM Class H stock. On December 31, 1985, General Motors merged Hughes Aircraft with its Delco Electronics unit to form Hughes Electronics Corporation, an independent subsidiary. The group then consisted of: Delco Electronics Corporation and Hughes Aircraft Company. In August of 1992 Hughes Aircraft completed its purchase of General Dynamics' missile businesses for $450 million. This brought the Tomahawk Cruise Missile, Advanced Cruise Missile, Standa ...

Thermal Imaging
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become ea ...

Smoke Grenade
Smoke grenades used at demonstrations in Paris, 2008 upBritish L83A1 Smoke Grenade manufactured in May 2008. This grenade has already been used. A smoke grenade is a canister-type grenade used as a signaling device, target or landing zone marking device, or as a screening device for unit movements. Smoke grenades generally emit a far larger amount of smoke than smoke bombs, which are a type of fireworks typically started with an external fuse rather than a pin and are more complex. Smoke grenades often cost around compared to smoke bombs, which can often cost just a few cents. The phrase "to smoke", meaning to fake, bluff, or beat around the bush, comes from the military usage of smoke grenades to obscure and conceal movement; similarly, "pop smoke", derived from a common way of ordering the use of smoke grenades, is used as a slang term for quickly leaving a place. __TOC__ Design left, Diagram and cross section of an AN M18 smoke grenade A typical design consists of a ...

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redundancy (engineering)
In engineering, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extraordinarily small; it is often outweighed by other risk factors, such as human error. Redundancy may also be known by the terms "m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...
