Armored Gun System
The Armored Gun System (AGS) was a U.S. Army competition in the 1990s to design a light tank to replace the M551 Sheridan and TOW-equipped HMMWVs. It was the ultimate incarnation of several research programs run in the 1970s with the aim of providing air-mobile light infantry forces with the firepower needed to last in the battlefield. There were three primary entries into the AGS contest. Cadillac Gage offered its Stingray light tank with the traditional four-man layout. FMC offered the Close Combat Vehicle Light (CCVL) with a three-man configuration. Teledyne offered its Expeditionary tank which had a two-man layout with an unmanned turret. In 1992, FMC's design was selected and given the name M8 Armored Gun System. However, purchases of the M8 were cancelled in 1997. The role was ultimately filled by the Stryker M1128 Mobile Gun System, which will be retired in 2022. In 2017, the Army requested proposals for the Mobile Protected Firepower requirement. The Army downselected BA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XM-8 AGS Fires Its 105mm Cannon In A California Test
The Heckler & Koch XM8 is a lightweight assault rifle system developed from the late 1990s to early 2000s. The rifle was designed by German small arms manufacturer Heckler & Koch (H&K), and shares design and engineering with their G36 rifle. The XM8 design was originally part of the Objective Individual Combat Weapon program (OICW), which was developing a "smart" grenade launcher system with an underslung carbine rifle. The system was unable to meet performance and weight requirements and was eventually canceled. In the aftermath, the two portions of the OICW were separated, resulting in the XM8 and XM25 projects. While the XM8 was being considered by the United States Army as a potential standard infantry rifle, to replace the M4 carbine, this project was put on hold in April 2005, and was formally canceled on October 31 of that year. The weapon was adopted by the Royal Malaysian Navy for its PASKAL special forces. History The U.S. Army's purpose in contracting for thi ...

MGM-51 Shillelagh
The Ford MGM-51 ''Shillelagh'' (MGM meaning Mobile Guided Missile) was an American anti-tank guided missile designed to be launched from a conventional gun (cannon). It was originally intended to be the medium-range portion of a short, medium, and long-range system for armored fighting vehicles in the 1960s and '70s to defeat future armor without an excessively large gun. Developing a system that could fire both shells and missiles reliably proved complex and largely unworkable. It was originally developed for the experimental but never produced MBT-70 tank and served most notably as a primary weapon of the M551 Sheridan light tank, but the missile system was not issued to units serving in South Vietnam and was retired in 1996. It was also used on the M60A2 "Starship", which was phased out by 1981. Ultimately, very few of the 88,000 rounds produced were ever fired in combat, and the system was largely succeeded by the later BGM-71 TOW wire-guided missile, which was first produced ...

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 cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Off-the-shelf
Commercial off-the-shelf or commercially available off-the-shelf (COTS) products are packaged or canned (ready-made) hardware or software, which are adapted aftermarket to the needs of the purchasing organization, rather than the commissioning of custom-made, or bespoke, solutions. A related term, Mil-COTS, refers to COTS products for use by the U.S. military. In the context of the U.S. government, the Federal Acquisition Regulation (FAR) has defined "COTS" as a formal term for commercial items, including services, available in the commercial marketplace that can be bought and used under government contract. For example, Microsoft is a COTS software provider. Goods and construction materials may qualify as COTS but bulk cargo does not. Services associated with the commercial items may also qualify as COTS, including installation services, training services, and cloud services. COTS purchases are alternatives to custom software or one-off developments – government-funded dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LAV-25
The LAV-25 is a member of the LAV II family. It is an eight-wheeled amphibious armored reconnaissance vehicle built by General Dynamics Land Systems and used by the United States Marine Corps and the United States Army. History During the 1980s, the U.S. Marine Corps began looking for a light armored vehicle to give their divisions greater mobility. In April 1981, the DoD opened submissions to the LAV program. Three contractors were downselected. *Alvis – A Scorpion 90 and a three Scorpion APCs. *Cadillac Gage – A V-150S (a stretched V-150) and a V-300. *General Motors of Canada (General Motors Diesel) – a license-built copy of the Mowag Piranha 8×8 The Marine Corps evaluated the three LAV submissions. In September 1982, the General Motors submission was selected. GM was awarded initial production contract for 969 LAVs. The Army type classified the 25 mm gun variant as the M1047. The Army sought 2,350 of the 12.7 mm (.50) caliber-armed light squad carrier variant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Ordnance L7
The Royal Ordnance L7, officially designated Gun, 105 mm, Tank, L7, is the basic model of the United Kingdom's most successful tank gun. The L7 is a 105 mm L/52 rifled design by the Royal Ordnance Factories intended for use in armoured fighting vehicles, replacing the earlier QF 20-pounder (84 mm) tank gun mounted on the Centurion tank. The successful L7 gun has been fitted on many armoured vehicles including the British Centurion (starting from the Mk. 5/2 variant), the German Leopard 1 and several variants of the US MBTs M48 Patton and M60 in an altered design, the M68. The L7 is a popular weapon and continued in use even after it was superseded by the L11 series 120 mm rifled tank gun, for some Centurion tanks operating as Artillery Forward Observation and Armoured Vehicle, Royal Engineers (AVRE) vehicles. The L7, and adaptations of it, can be found as standard or retrofitted equipment on a wide variety of tanks developed during the Cold War. History Both the U ...

Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M50 Ontos
Ontos, officially the Rifle, Multiple 106 mm, Self-propelled, M50, was a U.S. light armored tracked anti-tank vehicle developed in the 1950s. It mounted six 106 mm manually loaded M40 recoilless rifles as its main armament, which could be fired in rapid succession against single targets to increase the probability of a kill. Although the actual caliber of the main guns was 105 mm, it was designated 106 mm to prevent confusion with the ammunition for the 105 mm M27 recoilless rifle, which the M40 replaced. It was produced in limited numbers for the U.S. Marines after the U.S. Army cancelled the project. The Marines consistently reported excellent results when they used the Ontos for direct fire support against infantry in numerous battles and operations during the Vietnam War. The American stock of Ontos was largely expended towards the end of the conflict and the Ontos was removed from service in 1969. Development The ''Ontos'' (Greek for "thing") projec ...
