Meroka CIWS
The Meroka CIWS is a Spanish Navy 12 barrelled 20 mm CIWS, using twelve Oerlikon 20 mm/12 guns mounted in 2 rows of 6 guns each. The system's primary purpose is defence against anti-ship missiles, and other precision guided weapons. However it can also be employed against aircraft, ships and other small craft, coastal targets, and floating mines. The weapon is mounted primarily on Spanish naval vessels, from frigate size upwards. The term MeRoKa (from German ''Mehrrohrkanone'', meaning ''multi-barrelled gun'') can refer to weapons such as the Nordenfelt gun but is more commonly used referring to this naval CIWS defence system. The "Meroka" was developed and produced by the Spanish firm FABA Sistemas (''Fábrica de Artillería Bazán''). Description Unlike a rotary cannon, the Meroka CIWS uses individual guns firing in salvos or simultaneously; the barrels are purposely skewed in order to expand the impact area. The guns are mounted in an enclosed automatic turret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar Jamming
Radar jamming and deception is a form of electronic countermeasures that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic. Mechanical jamming entails reflecting enemy radio signals in various ways to provide false or misleading target signals to the radar operator. Electronic jamming works by transmitting additional radio signals towards enemy receivers, making it difficult to detect real target signals, or take advantage of known behaviors of automated systems like radar lock-on to confuse the system. Various counter-countermeasures can sometimes he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...

Naval Anti-aircraft Guns
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

Anti-aircraft Guns Of Spain
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft h ...

Volley Gun
A volley gun is a gun with multiple single-shot gun barrel, barrels that shoot projectiles in volley fire, either simultaneously or in succession. Although capable of unleashing intense firepower, volley guns differ from modern machine guns in that they lack Action (firearms)#Autoloading_operation, autoloading and automatic fire mechanisms, and therefore their volume of fire is limited by the number of barrels bundled together. In practice, large volley guns were not particularly more useful than a cannon firing canister shot or grapeshot. Since they were still mounted on a carriage, they could be as hard to aim and move around as a cannon, and the many barrels took as long or longer to reload.Matthew Sharpe "Nock's Volley Gun: A Fearful Discharge" ''American Rifleman'' December 2012 pp.50-53 They also tended to be relatively expensive since they were more complex than a cannon, due to all the barrels and ignition fuses, and each barrel had to be individually maintained and clea ...

Phalanx CIWS
The Phalanx CIWS (often spoken as "sea-wiz") is a gun-based close-in weapon system to defend military watercraft automatically against incoming threats such as aircraft, missiles, and small boats. It was designed and manufactured by the General Dynamics Corporation, Pomona Division,Thomas, Vincent C. ''The Almanac of Seapower 1987'' Navy League of the United States (1987) p.191 later a part of Raytheon. Consisting of a radar-guided Vulcan cannon mounted on a swiveling base, the Phalanx has been used by the United States Navy and the naval forces of 15 other countries. The US Navy deploys it on every class of surface combat ship, except the and . Other users include the British Royal Navy, the Royal Australian Navy, the Royal New Zealand Navy, the Royal Canadian Navy and the US Coast Guard (aboard its - and s). A land variant, the LPWS (Land Phalanx Weapon System), part of the C-RAM system, was developed. It was deployed to counter rocket, artillery and mortar attacks du ...

Gast Gun
The Gast gun was a German twin barrelled machine gun that was developed by Karl Gast of Vorwerk und Companie of Barmen and used during the First World War. Its unique operating system produced a very high rate of fire of 1,600 rounds per minute. The same principle was later used as the basis for the widely used Gryazev-Shipunov GSh-23L series of Russian aircraft autocannon. Description The weapon combines two barrels into a single mechanism so that the recoil from firing one barrel loads and charges the second. Ammunition feeds into the gun from two vertically mounted cylindrical drums, one on each side. The drums held 180 rounds of German 7.92 mm rifle ammunition, feeding them into the breech using a compressed spring. An experienced gunner could change ammunition drums in a few seconds. The weapon could fire single shots if one side of the mechanism had a problem. The gun's relative lightness at approximately without ammunition led to its airborne use; a telescopic si ...

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles. On December 13, 1926, Allan Lockheed, Jack Northrop, John Northrop, Kenneth K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Navy
The Spanish Navy or officially, the Armada, is the maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world. The Spanish Navy was responsible for a number of major historic achievements in navigation, the most famous being the discovery of America and the first global circumnavigation by Elcano. For several centuries, it played a crucial logistical role in the expansion and consolidation of the Spanish Empire, and defended a vast trade network across the Atlantic Ocean between the Americas and Europe, and the Manila Galleon across the Pacific Ocean between the Philippines and the Americas. The Spanish Navy was the most powerful maritime force in the world from the late 15th century to the early 18th century. In the early 19th century, with the loss of most of its empire, Spain transitioned to a smaller fleet but maintained a major shipbuilding industry which produced important technical innovations. The Spanish Navy built and oper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
