Intruder (air Combat)
An intruder is a military aircraft and its crew that is tasked with penetrating deep into enemy air space, to disrupt operations. Intruders are usually fighters, attackers or light bombers. The intruder concept dates from World War II, the first radar-equipped night and all-weather fighters were able to take advantage of the cover provided by night-time and meteorological conditions. Intruder crews attack enemy fighters, airfields, radar and other infrastructure; stage diversionary attacks; and escort bombers. Intruders often loiter in the vicinity of enemy airbases to attack aircraft as they take off or land. The technique was first used in World War II. Starting in July 1940, small numbers of German fast bombers would merge into streams of Royal Air Force bombers returning from night missions over Europe. Once past the Chain Home radars, where they appeared to be returning bombers, they were free to attack RAF air bases. This often took the form of dropping light bombs, ...

Penetrator (aircraft)
A penetrator is a long-range bomber aircraft designed to intrude against and penetrate enemy defenses. The term is mostly applied to aircraft that fly at low altitude to avoid radar, a strategic counterpart to the shorter-ranged tactical interdictor designs like the TSR-2 and F-111. The term can be applied to any aircraft that is designed to survive over enemy airspace, and has been used for the penetration fighter designs intended to escort bombers. The classic penetrator design is the Rockwell B-1 Lancer, where the term was first widely used. The larger Tupolev Tu-160 is also a member of this class. Other aircraft, like the Boeing B-52 Stratofortress and some versions of the F-111 have also been adapted to this role. More modern designs, like the Northrop Grumman B-2 Spirit, can be technically classified as penetrators, but the term is not generally applied to these aircraft.

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security". The R ...

Grumman A-6 Intruder
The Grumman A-6 Intruder is an American twinjet all-weather attack aircraft developed and manufactured by American aircraft company Grumman Aerospace and operated by the U.S. Navy and U.S. Marine Corps. It was designed in response to a 1957 requirement issued by the Bureau of Aeronautics for an all-weather attack aircraft for Navy long-range interdiction missions and with short takeoff and landing (STOL) capability for Marine close air support. It was to replace the piston-engined Douglas A-1 Skyraider. The requirement allowed one or two engines, either turbojet or turboprop. The winning proposal from Grumman used two Pratt & Whitney J52 turbojet engines. The Intruder was the first Navy aircraft with an integrated airframe and weapons system. Operated by a crew of two in a side-by-side seating configuration, the workload was divided between the pilot and weapons officer (bombardier/navigator (BN)). In addition to conventional munitions, it could also carry nuclear weapons, wh ...

Interdictor
An interdictor is a type of attack aircraft that operates far behind enemy lines, with the express intent of air interdiction of the enemy's military targets, most notably those involved in logistics. Interdiction prevents or delays enemy forces and supplies from reaching the battlefront; the term has generally fallen from use. The strike fighter is a closely related concept, but puts more emphasis on air-to-air combat capabilities as a multirole combat aircraft. Larger versions of the interdictor concept are generally referred to as "penetrators". In the post-war era, the RAF introduced interdictor variants of their English Electric Canberra jet bomber, as aircraft were released from the strategic bombing role as they were replaced by the new V bombers. Desiring a more modern aircraft for this role, development of the BAC TSR-2 (from "Tactical Strike and Reconnaissance, Mach 2") began, but this program was later cancelled. The US began development of a similar aircraft aroun ...

Serrate Radar Detector
Serrate was a World War II Allied radar detection and homing device used by night fighters to track Luftwaffe night fighters equipped with the earlier UHF-band ''BC'' and ''C-1'' versions of the Lichtenstein radar. It allowed RAF night fighters to attack their German counterparts, disrupting their attempts to attack the RAF's bomber force. The first Serrate systems were developed from the AI Mk. IV radar, which just happened to have antennas almost perfectly suited to receiving the Lichtenstein signals. Serrate simply disconnected the display from the radar's own transmitter and receiver and connected it to one tuned to the Lichtenstein. This produced a display indicating the direction to the German aircraft, but not the range. By carefully watching the movement of the target on the display the operator could estimate the range in general terms, near or far. When it appeared the target was close enough, the display was reconnected to the Mk. IV's own electronics to provide both rang ...

Occupied Europe
German-occupied Europe refers to the sovereign countries of Europe which were wholly or partly occupied and civil-occupied (including puppet governments) by the military forces and the government of Nazi Germany at various times between 1939 and 1945, during and shortly before World War II, generally administered by the Nazi regime, under the dictatorship of Adolf Hitler.Encyclopædia Britannica German occupied Europe.World War II. Retrieved 1 September 2015 from the Internet Archive. The German Wehrmacht occupied European territory: * as far east as the town of Mozdok in the North Caucasus in the Soviet Union (1942–1943) * as far north as the settlement of Barentsburg in Svalbard in the Kingdom of Norway * as far south as the island of Gavdos in the Kingdom of Greece * as far west as the island of Ushant in the French Republic Outside of Europe proper, German forces effectively controlled areas of North Africa in Egypt, Libya, and Tunisia at times between 1941 and 1943.

De Havilland Mosquito
The de Havilland DH.98 Mosquito is a British twin-engined, shoulder-winged, multirole combat aircraft, introduced during the Second World War. Unusual in that its frame was constructed mostly of wood, it was nicknamed the "Wooden Wonder", or "Mossie". Lord Beaverbrook, Minister of Aircraft Production, nicknamed it "Freeman's Folly", alluding to Air Chief Marshal Sir Wilfrid Freeman, who defended Geoffrey de Havilland and his design concept against orders to scrap the project. In 1941, it was one of the fastest operational aircraft in the world.Bowman 2005, p. 21. Originally conceived as an unarmed fast bomber, the Mosquito's use evolved during the war into many roles, including low- to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, maritime strike, and photo-reconnaissance aircraft. It was also used by the British Overseas Airways Corporation as a fast transport to carry small, high-value c ...

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 airborne 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) also m ...

Douglas A-20 Havoc
The Douglas A-20 Havoc (company designation DB-7) is an American medium bomber, attack aircraft, Intruder (air combat), night intruder, night fighter, and reconnaissance aircraft of World War II. Designed to meet an Army Air Corps requirement for a bomber, it was ordered by France for their air force before the USAAC decided it would also meet their requirements. French DB-7s were the first to see combat; after the fall of France, the bomber served with the Royal Air Force under the British military aircraft designation systems#Names, service name Boston. From 1941, night fighter and Intruder (air combat), intruder versions were given the service name Havoc. In 1942 USAAF A-20s saw combat in North Africa. It served with several Allies of World War II, Allied air forces, principally the United States Army Air Forces (USAAF), the Soviet Air Forces (''VVS''), Soviet Naval Aviation (''AVMF''), and the Royal Air Force (RAF) of the United Kingdom. A total of 7,478 aircraft were built, ...

Hawker Hurricane
The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–40s which was designed and predominantly built by Hawker Aircraft Ltd. for service with the Royal Air Force (RAF). It was overshadowed in the public consciousness by the Supermarine Spitfire during the Battle of Britain in 1940, but the Hurricane inflicted 60 percent of the losses sustained by the Luftwaffe in the campaign, and fought in all the major theatres of the Second World War. The Hurricane originated from discussions between RAF officials and aircraft designer Sir Sydney Camm about a proposed monoplane derivative of the Hawker Fury biplane in the early 1930s. Despite an institutional preference for biplanes and lack of interest by the Air Ministry, Hawker refined their monoplane proposal, incorporating several innovations which became critical to wartime fighter aircraft, including retractable landing gear and the more powerful Rolls-Royce Merlin engine. The Air Ministry ordered Hawker's ''Int ...

Butterfly Bomb
A Butterfly Bomb (or ''Sprengbombe Dickwandig 2 kg'' or SD 2) was a German anti-personnel submunition used by the Luftwaffe during the Second World War. It was so named because the thin cylindrical metal outer shell which hinged open when the bomblet deployed gave it the superficial appearance of a large butterfly. The design was very distinctive and easy to recognise. SD 2 bomblets were not dropped individually, but were packed into containers holding between 6 and 108 submunitions e.g. the AB 23 SD 2 and AB 250-3 submunition dispensers. The SD 2 submunitions were released after the container was released from the aircraft and had burst open. Because SD 2s were always dropped in groups (never individually) the discovery of one unexploded SD 2 was a reliable indication that others had been dropped nearby. This bomb type was one of the first cluster bombs ever used in combat and it proved to be a highly effective weapon. The bomb containers that carried the SD 2 bomblets and ...

Chain Home
Chain Home, or CH for short, was the codename for the ring of coastal Early Warning radar stations built by the Royal Air Force (RAF) before and during the Second World War to detect and track aircraft. Initially known as RDF, and given the official name Air Ministry Experimental Station Type 1 (AMES Type 1) in 1940, the radar units themselves were also known as Chain Home for most of their life. Chain Home was the first early warning radar network in the world, and the first military radar system to reach operational status. Its effect on the outcome of the war made it one of the most powerful weapons of what is today known as the "Wizard War". In late 1934, the Tizard Committee asked radio expert Robert Watson-Watt to comment on the repeated claims of radio death rays and reports suggesting Germany had built some sort of radio weapon. His assistant, Arnold Wilkins, demonstrated that a death ray was impossible but suggested radio could be used for long-range detection. In Febr ...
