Oerlikon GDF
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 were aimed either directly, by way of an advanced sighting system, or automatically, by locking onto the target wi ...

Aspide
Aspide, named for the asp, is an Italian medium range air-to-air and surface-to-air missile produced by Selenia and its successors, Alenia Aeronautica and MBDA that was developed in the 1970s to replace license built AIM-7 Sparrows then in use on Italian Air Force F-104S Starfighter interceptors. It is similar in appearance to the Sparrow, with original versions sharing an airframe with the type and all using a similar semi-active radar homing seeker. This similarity in appearance combined with Selenia's license production of Sparrows has to lead non-Italian press frequently referring to the missile as a Sparrow variant. Compared to Sparrow, Aspide features an inverse monopulse seeker that is far more accurate and much less susceptible to ECM than the original continuous-wave version. Aspide also features new electronics, a new warhead, and a new, more powerful engine. Closed-loop hydraulics were also substituted for Sparrow's open-loop type, which gave Aspide better downr ...

Self-propelled Anti-aircraft Weapon
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft warfare, anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or surface-to-air missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir missile system). Platforms used include both trucks and heavier combat vehicles such as armoured personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing gun turret, turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, surface-to-air missiles (generally mounte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-7 Sea Sparrow
The RIM-7 Sea Sparrow is a U.S. ship-borne short-range Surface-to-air missile, 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 resembl ...

AIM-7 Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers, and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made it difficult to achieve lock-on at the missile's effective range. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat the enemy fighter would often approach within ...

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 or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, 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. T ...

Swiss Air Force
The Swiss Air Force (; ; ; ) is the air component of the Swiss Armed Forces, established on 31 July 1914, three days after the outbreak of World War I, as a part of the Swiss Army, 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 (aeronautics), 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 civilian aircraft at Bern's air ...

Radar Configurations And Types
This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The radio waves are usually less than a meter long. Ships and planes are metal, and reflect radio waves. The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the ''range gate''. The radar determines the direction because the short radio waves behave like a search light when emitted from the reflector of the radar set's antenna.

Pulse-Doppler Radar
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics. The first operational pulse-Doppler radar was in the CIM-10 Bomarc, an American long range supersonic missile powered by ramjet engines, and which was armed with a W40 nuclear weapon to destroy entire formations of attacking enemy aircraft. Pulse-Doppler systems were first widely used on fighter aircraft starting in the 1960s. Earlier radars had used pulse-timing in order to determine range and the angle of the antenna (or similar means) to determine the bearing. However, this only worked when the radar antenna was not pointed down; in that case the reflection off the ground overwhelmed any returns from other objects. As the ground moves at th ...
