Carpet (jammer)
Carpet was an early radar jamming apparatus developed by the Allies in 1942. It was installed on strategic bombers like the B-17 from late 1943 and used alongside window to defeat German gun-laying radar. By the end of World War II, two were installed in most Eighth Air Force bombers. The Würzburg radar was one of the most common in German use, and directed German flak batteries, so the British spent considerable effort countering the system during the war. In February 1942, a Würzburg-A system at Bruneval on the coast of France was captured by British Paratroopers in Operation Biting. Several key components were returned to the UK, which allowed the operational parameters of the system to be accurately determined. This led to the modification of existing transmitter systems to produce the "Carpet" system that broadcast noise on the frequencies used by particular Würzburg systems. Several updated versions of Carpet were introduced; Carpet II was the primary UK version while Car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Jamming
Radar jamming and deception is a form of electronic countermeasures (ECMs) 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 Electronic counter-countermeasur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Biting
Operation Biting, also known as the Bruneval Raid, was a British Combined Operations (United Kingdom), Combined Operations Raid (military), raid on a German coastal radar installation at Bruneval in northern France, during the Second World War, on the night . Several of these installations were identified from Royal Air Force (RAF) aerial reconnaissance photographs during 1941, but the purpose and the nature of the equipment was not known. Some British scientists believed that these stations were connected with successful German attacks on RAF bombers conducting bombing raids against targets in German-occupied Europe, Occupied Europe, resulting in severe losses of pilots and bombers. The scientists requested that one of these installations be raided and the technology it possessed be studied and, if possible, extracted and brought back to Britain for further examination. Due to the extensive Coastal defence and fortification, coastal defences erected by the Germans to protect t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weapons Countermeasures
A weapon, arm, or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or Death, kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime (e.g., murder), law enforcement, self-defense, warfare, or suicide. In a broader context, weapons may be construed to include anything used to gain a tactical, strategic, material, or mental advantage over an adversary or enemy target. While ordinary objects such as rock (geology), rocks and bottles can be improvised weapon, used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as club (weapon), clubs and swords to complicated modern firearms, tanks, missiles and biological warfare, biological weapons. Something that has been repurposed, converted, or enhanced to become a weapon of war is termed ''weaponized'', such as a biological warfare, weaponized virus or laser weapon, weaponized laser.

Penetration Aids
A penetration aid (or "penaid") is a device or tactic used to increase an aircraft's capability of reaching its target without detection, and in particular intercontinental ballistic missile (ICBM) warhead's chances of penetrating a target's defenses. These can consist of both ''physical devices'' carried within the ICBM (as part of its payload), as well as ''tactics'' that accompany its launch or flight path, operate as either passive or active counters, and may include one or more of the following concepts: * The missile booster can have a short burn time, and/or (if existing) the MIRV bus carrying the nuclear warheads can have some form of stealth technology, thereby hindering detection before the warhead reentry vehicles are released. * MIRV and MRV (instead of single warhead missiles) themselves largely improve penetration since there are many more warheads to destroy than missiles, which may saturate the defensive system's stock of weapons. However, these technologies are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Technology
Military technology is the application of technology for use in warfare. It comprises the kinds of technology that are distinctly military in nature and not civilian in application, usually because they lack useful or legal civilian applications, or are dangerous to use without appropriate military training. The line is porous; military inventions have been brought into civilian use throughout history, with sometimes minor modification if any, and civilian innovations have similarly been put to military use. Military technology is usually researched and developed by scientists and engineers specifically for use in battle by the armed forces. Many new technologies came as a result of the military funding of science. On the other hand, the theories, strategies, concepts and doctrines of warfare are studied under the academic discipline of military science. Armament engineering is the design, development, testing and lifecycle management of military weapons and systems. It draws ...

Military Equipment Introduced From 1940 To 1944
A military, also known collectively as armed forces, is a heavily Weapon, armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstructi ...

Blind Bombing
Oboe was a British bomb aiming system developed to allow their aircraft to bomb targets accurately in any type of weather, day or night. Oboe coupled radar tracking with radio transponder technology. The guidance system used two well-separated radar stations to track the aircraft. Two circles were created before the mission, one around each station, such that they intersected at the bomb drop point. The operators used the radars, aided by transponders on the aircraft, to guide the bomber along one of the two circles and drop the bombs when they reached the intersection. The system was developed in 1942 by the Telecommunications Research Establishment at Malvern in Worcestershire, working in close association with 109 Squadron. By December 1942 a working system had been developed. The first major use of Oboe was in March 1943 when the system was used to mark the Krupp Works in an attack against Essen. Over the course of the month the system was used with great success to mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrage Jamming
Barrage jamming is an electronic warfare technique that attempts to blind (" jam") radar systems by filling the display with noise, rendering the broadcaster's ''blip'' invisible on the display, and often those in the nearby area as well. "Barrage" refers to systems that send signals in many bands of frequencies compared to the bandwidth of any single radar. This allows the jammer to jam multiple radars at once, and reduces or eliminates the need for adjustments to respond to any single radar. Early radar systems typically operated on a single frequency, and could only change that frequency by changing internal electronics. Against these radars, it was possible to use conventional radio sets to send out signals on the same band, causing the radar display to be filled with noise whenever the antenna was pointed in the general direction of the jammer. However, given that each individual radar would be operating on different frequencies, this " spot jamming" technique required mu ...

2nd Battalion, Parachute Regiment
The Second Battalion, Parachute Regiment (2 PARA), is a formation of the Parachute Regiment, part of the British Army, and subordinate unit within 16th Air Assault Brigade. 2 PARA is an airborne light infantry battalion capable of a wide range of operational tasks, based at Merville Barracks, Colchester Garrison, England. Personnel regularly deploy outside the United Kingdom on operations and training. History The 2nd Battalion was formed on 30 September 1941, as the 2nd Parachute Battalion, and later became part of the Army Air Corps. The battalion took part in its first active operation over the night of 27–28 February 1942, Operation Biting, the raid on Bruneval in France.see In honour of the operation, C Company of the battalion took the nickname 'C (Bruneval) Company'. On 1 August of the same year, the battalion was renamed the 2nd Battalion, the Parachute Regiment. The battalion was part of the 1st Parachute Brigade, 1st Airborne Division, and fought in the ...

B-17
The Boeing B-17 Flying Fortress is an American four-engined heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber, the B-17 dropped more bombs than any other aircraft during World War II, used primarily in the European Theater of Operations. It is the third-most produced bomber in history, behind the American four-engined Consolidated B-24 Liberator and the German multirole, twin-engined Junkers Ju 88. The B-17 was also employed in transport, anti-submarine warfare, and search and rescue roles. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, which were introduced into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (from 1941 the United States Army Air Forces, USAAF) pro ...

Flak
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface ( submarine-launched), and air-based weapon systems, in addition to 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 defense. Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 'tiers' of air defence systems which, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
