Oerlikon 35 Mm Twin Cannon
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves (renamed as ''Rheinmetall Air Defence AG'' following the merger with Rheinmetall in 2009). The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries. Design and development The system uses twin autocannons, firing 35×228mm NATO-standard ammunition. It was originally designated 353 MK and is now designated as the KD series. The same KD series 35mm cannons are used in the Leopard 1 based Gepard and Type 74 tank based Type 87 SPAAG and Marksman self-propelled anti-aircraft guns (SPAAG). The system could be paired with the off-gun (remote) ''Super Fledermaus'' fire control radar, which in the late 1970s was upgraded to the ''Skyguard'' system. The weapons was aimed either directly, by way of an advanced sighting system, or automatically, by locking onto the target with ...

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 ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Navantia
Navantia is a Spanish state-owned shipbuilding company, which offers its services to both military and civil sectors. It is the fifth-largest shipbuilder in Europe and the ninth-largest in the world with shipyards around the globe. The heir to the segregation of the military assets of the IZAR Group in 2005, Navantia designs, builds and supports all types of surface vessels, submarines and systems. In addition, it is expanding into new markets diversifying its product, such as renewable energy, the offshore industry and all kinds of services that it requires by the naval industry. Company The origins of Navantia go back to the origins of Spanish naval construction, from the 13th century with Alfonso X with the Real Atarazanas de Sevilla and the Real Carenero of San Fernando, which took great relevance during the discovery of America until due to the increase of the size of the ships and their greater draft, in 1730 they were replaced by the historical military Arsenal de Fe ...

Aspide
Aspide (the Italian name for the asp) is an Italian medium range air-to-air and surface-to-air missile produced by Selenia (then by Alenia Aeronautica, now a part of Leonardo S.p.A.). It is provided with semi-active radar homing seeker. It is very similar to the American AIM-7 Sparrow, using the same airframe, but uses an inverse monopulse seeker that is far more accurate and much less susceptible to ECM than the original conical scanning version. This resemblance, and that Selenia was provided with the technology know-how of the AIM-7 (around 1,000 of which it had produced under licence), has generally led non-Italian press to refer to the Aspide as a Sparrow variant. However, the Aspide had original electronics and warhead, and a new and more powerful engine. Closed-loop hydraulics were also substituted for Sparrow's open-loop type, which gave Aspide better downrange maneuverability. Even the control surfaces are different, replacing the original triangular wings, fixed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-7 Sea Sparrow
RIM-7 Sea Sparrow is a U.S. ship-borne short-range anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a lightweight "point-defense" weapon that could be retrofitted to existing ships as quickly as possible, often in place of existing gun-based anti-aircraft weapons. In this incarnation, it was a very simple system guided by a manually aimed radar illuminator. After its introduction, the system underwent significant development into an automated system similar to other US Navy missiles like the RIM-2 Terrier. Contemporary improvements being made to the Sparrow for the air-to-air role led to similar improvements in the Sea Sparrow through the 1970s and 80s. After that point the air-to-air role passed to the AIM-120 AMRAAM and the Sea Sparrow underwent a series of upgrades strictly for the naval role. It now resembles the AIM-7 only in general ...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swiss Air Force
The Swiss Air Force (german: Schweizer Luftwaffe; french: Forces aériennes suisses; it, Forze aeree svizzere; rm, Aviatica militara svizra) is the air component of the Swiss Armed Forces, established on 31 July 1914 as a part of the army and in October 1936 as an independent service. In peacetime, Dübendorf is the operational air force headquarters. The Swiss Air Force operates from several fixed bases (see current status) but its personnel are also trained to carry out air operations from temporary highway airstrips. In case of crisis or war, several stretches of road are specially prepared for this option. History Early years The first military aviation in Switzerland took the form of balloon transport, pioneered by Swiss balloonist Eduard Spelterini, but by 1914 there was still little official support for an air corps. The outbreak of World War I changed opinions drastically and cavalry officer Theodor Real was charged with forming a flying corps. He commandeered three ...

J Band (NATO)
The NATO J band is the designation given to the radio frequencies from 10 to 20 GHz (equivalent to wavelengths between 3 and 1.5 cm). Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults.
