Spaniel (missile)
Spaniel was a series of experimental British missiles of the Second World War. They began as surface-to-air missile designs developed by the Air Ministry from 1941. Based on the 3-inch Unrotated Projectile anti-aircraft rocket, it proved to have too little performance to easily reach typical bomber altitudes, leading to further development as an air-to-air missile carried aloft by heavy fighters. Some progress had been made by 1942 when the program was cancelled as the threat of German air attack dwindled. Further research was directed at a dedicated air-to-air design, Artemis. Spaniel SAMs Development of cast solid fuel rockets began at the Woolwich Arsenal in the years immediately before the opening of World War II. This research was moved to the newly-formed Ministry of Supply Projectile Development Establishment at Fort Halstead. Three designs were initially developed under the name Unrotated Projectile, a diameter short-range weapon, a short-range weapon that carried a lar ...

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 ...

Searchlight
A searchlight (or spotlight) is an apparatus that combines an extremely luminosity, bright source (traditionally a carbon arc lamp) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction. It is usually constructed so that it can be swiveled about. The most common element used in modern searchlights is Xenon, Xenon (Xe). However, Rare-earth elements such as lanthanum, lanthanum (La) and cerium, cerium (Ce) are used in phosphors to improve light quality in some specialized searchlights. Military use The first use of searchlights using carbon arc technology occurred during the Siege of Paris (1870-71), Siege of Paris during the Franco-Prussian War. The Royal Navy used searchlights in 1882 to dazzle and prevent Egyptian forces from manning artillery batteries at Bombardment of Alexandria, Alexandria. Later that same year, the French and British forces landed troops under searchlights. By 1907 the value o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Beaufighter
The Bristol Type 156 Beaufighter (often called the Beau) is a British multi-role aircraft developed during the Second World War by the Bristol Aeroplane Company. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber. The Beaufighter proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain, its large size allowing it to carry heavy armament and early aircraft interception radar without major performance penalties. The Beaufighter was used in many roles; receiving the nicknames ''Rockbeau'' for its use as a rocket-armed ground attack aircraft and ''Torbeau'' as a torpedo bomber against Axis shipping, in which it replaced the Beaufort. In later operations, it served mainly as a maritime strike/ground attack aircraft, RAF Coastal Command having operated the largest number of Beaufighters amongst all other commands at one point. The Royal Australian Air Force (RAAF) al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftwaffe
The Luftwaffe () was the aerial warfare, aerial-warfare branch of the before and during World War II. German Empire, Germany's military air arms during World War I, the of the Imperial German Army, Imperial Army and the of the Imperial German Navy, Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles, which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk (air base), Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe's existence was publicly acknowledged and officially established on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist faction (Spanish Civil War), Nationalist for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GL Mark III Radar
Radar, Gun Laying, Mark III, or GL Mk. III for short, was a radar system used by the British Army to directly guide, or ''Gun laying, lay'', anti-aircraft artillery (AA). The GL Mk. III was not a single radar, but a family of related designs that saw constant improvement during and after World War II. These were renamed shortly after their introduction in late 1942, becoming the Radar, AA, No. 3, and often paired with an early warning radar, the AA No. 4, which was also produced in several models. The Mk. III began development shortly after introducing the cavity magnetron in early 1940. The magnetron allowed radar systems to operate at microwave frequencies, greatly reducing the size of their antennas and making them much more mobile and accurate. Having originally started work on the magnetron as part of the AI Mk. VIII radar, AI Mk. VIII aircraft interception radar, air-to-air radar, the team was told to drop everything and develop a radar for AA use as quickly as possible. Thi ...
