United States Army Air Defense
United States Army air defense relies on a range of ground launched missiles ranging from hand held to vehicle mounted systems. The Air Defense Artillery is the branch that specializes in anti-aircraft weapons (such as surface-to-air missiles). In the US Army, these groups are composed of mainly air defense systems such as the PATRIOT Missile System, Terminal High Altitude Air Defense, and the Avenger Air Defense system which fires the FIM-92 Stinger missile. The Air Defense Artillery branch descended from the Anti-Aircraft Artillery (part of the Field Artillery) into a separate branch on 20 June 1968. History During World War II, US Army anti-aircraft systems were quite competent. Their smaller tactical needs were filled with four M2 (.50 BMG, .50 caliber) machine guns linked together (known as the "Quad Fifty"), which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft. Although of even less power than Germany's 20 mm syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M24 Chaffee
The M24 Chaffee (officially Light Tank, M24) was an American light tank used during the later part of World War II; it was also used in post–World War II conflicts including the Korean War, and by the French in the War in Algeria and the First Indochina War. In British service it was given the service name Chaffee after the United States Army General Adna R. Chaffee Jr., who helped develop the use of tanks in the United States armed forces. Although the M41 Walker Bulldog was developed as a replacement, M24s were not mostly removed from U.S. and NATO armies until the 1960s and remained in service with some Third World countries. Development and production history British combat experience in the North African campaign identified several shortcomings of the M3 Stuart light tank, especially the performance of its 37 mm cannon. A 75 mm gun was experimentally fitted to a Howitzer Motor Carriage M8 – an M3 tank with a larger turret – and trials indicated that a 7 ...

AIM-9 Sidewinder
The AIM-9 Sidewinder (where "AIM" stands for "Air Intercept Missile") is a short-range air-to-air missile which entered service with the US Navy in 1956 and subsequently was adopted by the US Air Force in 1964. Since then the Sidewinder has proved to be an enduring international success, and its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 'Atoll'), a reverse-engineered copy of the AIM-9B, was also widely adopted by a number of nations. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile. Originally a tail-chasing system, early models saw extensive use during the Vietnam War but had a low success rate. This led to all-aspect capabilities in ...

MIM-72 Chaparral
The MIM-72A/M48 Chaparral is an American-made self-propelled surface-to-air missile system based on the AIM-9 Sidewinder air-to-air missile system. The launcher is based on the M113 family of vehicles. It entered service with the United States Army in 1969 and was phased out between 1990 and 1998. It was intended to be used along with the M163 VADS, the Vulcan ADS covering short-range short-time engagements, and the Chaparral for longer range use. Development Mauler Starting in 1959 the U.S. Army MICOM (Missile Command) began development of an ambitious anti-aircraft missile system under their "Forward Area Air Defense" (FAAD) program. Known as the MIM-46 Mauler, it was based on a modified M113 chassis carrying a large rotating A-frame rack on top with nine missiles and both long-range search and shorter-range tracking radars. Operation was to be almost entirely automatic, with the operators simply selecting targets from the search radar's display and then pressing "fire". The ...

M61 Vulcan
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by General Dynamics. Development At the end of World War II, the United States Army Air Forces began to consider new directions for future military aircraft guns. The higher speeds of jet-powered fighter aircraft meant that achieving an effective number of hits would be extremely difficult without a much higher volume of fire. While captured German designs (principally the Mauser MG 213C) showed the potential of the single-barrel revolver cannon, the practical rate of fire of such a design was still lim ...

M163 VADS
The M163 Vulcan Air Defense System (VADS) is a self-propelled anti-aircraft gun (SPAAG) that was used by the United States Army. The M168 gun is a variant of the General Dynamics M61 Vulcan rotary cannon, the standard cannon in most U.S. combat aircraft since the 1960s, mounted on either an armored vehicle or a trailer. Technical description The weapon is mounted on a modified M113 vehicle (the M741 carrier). The system was designed to complement the M48 Chaparral missile system. The M163 uses a small, range-only radar, the AN/VPS-2, and an M61 optical lead-calculating sight. The system is suitable for night operations with the use of AN/PVS series night vision sights that can be mounted to the right side of the primary sight. The gun fires at 3,000 rounds per minute in short bursts of 10, 30, 60, or 100 rounds, or it can fire in continuous fire mode at a rate of 1,000 rounds per minute. A linkless feed system is used. Performance The M163 had a fairly limited range from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIM-46 Mauler
The General Dynamics Mauler was a self-propelled anti-aircraft missile system designed to a late 1950s US Army requirement for a system to combat low-flying high-performance tactical fighters and short-range ballistic missiles. The system was a XM546 vehicle, based on the M113 chassis, carrying nine MIM-46 missiles in launch canisters, a tracking and illumination continuous wave radar, and the fire control system. An ambitious design for its era, the Mauler ran into intractable problems during development, and was eventually canceled in November 1965. Cancellation of Mauler left the US Army with no modern anti-aircraft weapon, and they rushed development of the much simpler MIM-72 Chaparral and M163 Tracked Vulcan to fill this niche. These weapons were much less capable than Mauler, and were intended solely as a stop-gap solution until more capable vehicles were developed. In spite of this, no real replacement entered service until the late 1990s. Both the US Navy and Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gatling Gun
The Gatling gun is a rapid-firing multiple-barrel firearm invented in 1861 by Richard Jordan Gatling. It is an early machine gun and a forerunner of the modern electric motor-driven rotary cannon. The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing-reloading sequence. As the handwheel is cranked, the barrels rotate and each barrel sequentially loads a single cartridge from a top-mounted magazine, fires off the shot when it reaches a set position (usually at 4 o'clock), then ejects the spent casing out of the left side at the bottom, after which the barrel is empty and allowed to cool until rotated back to the top position and gravity-fed another new round. This configuration eliminated the need for a single reciprocating bolt design and allowed higher rates of fire to be achieved without the barrels overheating quickly. One of the best-known early rapid-fire firearms, the Gatling gun saw occasional use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T249 Vigilante
The T249 Vigilante was a prototype 37 mm self-propelled anti-aircraft gun (SPAAG) designed as a replacement for the Bofors 40 mm gun and M42 Duster in US Army service. The system consisted of a 37 mm T250 six-barrel Gatling gun mounted on a lengthened M113 armored personnel carrier platform. By the early 1960s, the US Army declared that gun-based systems were outdated, and canceled further development in favor of the MIM-46 Mauler missile system that also failed to enter service. The designer, the Sperry Utah Engineering Laboratory, later revived the Vigilante, rechambering it for NATO-standard 35×228mm rounds and mounting it on a M48 Patton tank chassis for the Division Air Defense (DIVAD) contest. However, it ultimately lost to Ford's M247 Sergeant York that also failed to enter service. Development Very little information exists of the T249 Vigilante and its T250 cannon. The conceptual design for the T250 cannon was initiated in 1956. While the design of can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

M42 Duster
The M42 40 mm Self-Propelled Anti-Aircraft Gun, or "Duster," is an American armored light air-defense gun built for the United States Army from 1952 until December 1960, in service until 1988. Production of this vehicle was performed by the tank division of the General Motors Corporation. It used components from the M41 light tank and was constructed of all-welded steel. A total of 3,700 M42s were built. The vehicle has a crew of six and weighs 22,500 kg (49,500 lb) fully loaded. Maximum speed is with a range of 100 miles (160 km). Armament consists of fully automatic twin 40 mm M2A1 Bofors, with a rate of fire of 2×120 rounds per minute (rpm) enabling nearly 85 seconds of fire time before running out of ammo, and either a .30 caliber Browning M1919A4 or 7.62mm M60 machine gun. The 500 hp, six-cylinder, Continental (or Lycoming Engines), air-cooled, gasoline engine is located in the rear of the vehicle. It was driven by a cross-drive, two-s ...
