A night fighter is a largely historical term for a fighter or interceptor aircraft adapted or designed for effective use at night, during periods of adverse meteorological conditions, or in otherwise poor visibility. Such designs were in direct contrast to day fighters; fighters and interceptors designed primarily for use during the day or during good weather. The concept of the night fighter was developed and experimented with during the First World War but would not see widespread use until WWII. The term would be supplanted by “all-weather fighter/interceptor” post-WWII, with advancements in various technologies permitting the use of such aircraft in virtually all conditions.
The Focke-Wulf Ta 154 Moskito was a fast twin-engined German night fighter aircraft designed by Kurt Tank and produced by Focke-Wulf during late World War II. Only a few were produced, proving to have less impressive performance than the prototypes.
The Heinkel He 219 Uhu ("Eagle-Owl") is a night fighter that served with the German Luftwaffe in the later stages of World War II. A relatively sophisticated design, the He 219 possessed a variety of innovations, including Lichtenstein SN-2 advanced VHF-band intercept radar, also used on the Ju 88G and Bf 110G night fighters. It was also the first operational military aircraft to be equipped with ejection seats and the first operational German World War II-era aircraft with tricycle landing gear. Had the Uhu been available in quantity, it might have had a significant effect on the strategic night bombing offensive of the Royal Air Force; however, only 294 of all models were built by the end of the war and these saw only limited service. Ernst-Wilhelm Modrow was the leading night fighter ace on the He 219. Modrow was credited with 33 of his 34 night air victories on the type.
The Junkers Ju 88 is a German World War II Luftwaffe twin-engined multirole combat aircraft. Junkers Aircraft and Motor Works (JFM) designed the plane in the mid-1930s as a so-called Schnellbomber that would be too fast for fighters of its era to intercept. It suffered from technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other Luftwaffe bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb.
Monica was a range-only tail warning radar for bombers, introduced by the RAF in June 1942. Officially known as ARI 5664, it operated at frequencies of around 300 MHz. The system was also used by the US Army Air Forces, under the name AN/APS-13, and the nickname Archie.
The FuG 227 Flensburg was a German passive radar receiver developed by Siemens & Halske and introduced into service in early 1944. It used wing and tail-mounted dipole antennae and was sensitive to the mid-VHF band frequencies of 170–220 MHz, subharmonics of the Monica radar's 300 MHz transmissions. It allowed Luftwaffe nightfighters to home in on the Monica tail warning radar fitted to RAF bombers.
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.
During World War II, the German Luftwaffe relied on an increasingly diverse array of electronic communications, IFF and RDF equipment as avionics in its aircraft and also on the ground. Most of this equipment received the generic prefix FuG for Funkgerät, meaning "radio equipment". Most of the aircraft-mounted Radar equipment also used the FuG prefix. This article is a list and a description of the radio, IFF and RDF equipment.
Wilde Sau was the term given by the Luftwaffe to the tactic used from 1943 to 1944 during World War II by which British night bombers were engaged by single-seat day-fighter aircraft flying in the Defence of the Reich.
Nachtjagdgeschwader 1 (NJG 1) was a German Luftwaffe night fighter-wing of World War II. NJG 1 was formed on 22 June 1940 and comprised four Gruppen (groups). NJG 1 was created as an air defence unit for the Defence of the Reich campaign; an aerial war waged by the Luftwaffe against the bombing of the German Reich by RAF Bomber Command and the United States Air Force. In 1941 airborne radar was introduced with radar operators, and standardised in 1942 and 1943. Consequently, a large number of German night fighter aces existed within NJG 1.
Nachtjagdgeschwader 2 was a German Luftwaffe night fighter and night intruder wing during World War II.
Nachtjagdgeschwader 5 was a Luftwaffe night fighter-wing of World War II. NJG 5 was formed on 30 September 1942 in Döberitz.
Gerhard Ferdinand Otto Raht was a German Luftwaffe military aviator during World War II, a night fighter ace credited with 58 aerial victories claimed in 171 combat missions making him the tenth most successful night fighter pilot in the history of aerial warfare. All of his victories were claimed over the Western Front in Defense of the Reich missions against the Royal Air Force's (RAF) Bomber Command.
Radar in World War II greatly influenced many important aspects of the conflict. This revolutionary new technology of radio-based detection and tracking was used by both the Allies and Axis powers in World War II, which had evolved independently in a number of nations during the mid 1930s. At the outbreak of war in September 1939, both the United Kingdom and Germany had functioning radar systems. In the UK, it was called RDF, Range and Direction Finding, while in Germany the name Funkmeß (radio-measuring) was used, with apparatuses called Funkmessgerät . By the time of the Battle of Britain in mid-1940, the Royal Air Force (RAF) had fully integrated RDF as part of the national air defence.
The FuG 200 Hohentwiel was a low-UHF band frequency maritime patrol radar system of the Luftwaffe in World War II. It was developed by C. Lorenz AG of Berlin starting in 1938 under the code name "Hohentwiel", an extinct volcano in the region of Baden-Württemberg in southern Germany.
Neptun (Neptune) was the code name of a series of low-to-mid-VHF band airborne intercept radar devices developed by Germany in World War II and used as active targeting devices in several types of aircraft. They were usually combined with a "backwards warning device", indicated by the addition of the letters "V/R" Vorwärts/Rückwärts, meaning Forward/Backward). Working in the metre range, Neptun was meant as a stop-gap until scheduled SHF-band devices became available.
The FuG 240 "Berlin" was an airborne interception radar system operating at the "lowest end" of the SHF radio band, which the German Luftwaffe introduced at the very end of World War II. It was the first German radar to be based on the cavity magnetron, which eliminated the need for the large multiple dipole-based antenna arrays seen on earlier radars, thereby greatly increasing the performance of the night fighters. Introduced by Telefunken in April 1945, only about 25 units saw service.
Radar, Airborne Interception, Mark IV, produced by USA as SCR-540, was the world's first operational air-to-air radar system. Early Mk. III units appeared in July 1940 on converted Bristol Blenheim light bombers, while the definitive Mk. IV reached widespread availability on the Bristol Beaufighter heavy fighter by early 1941. On the Beaufighter, the Mk. IV arguably played a role in ending the Blitz, the Luftwaffe's night bombing campaign of late 1940 and early 1941.
German Luftwaffe and Kriegsmarine Radar Equipment during World War II, relied on an increasingly diverse array of communications, IFF and RDF equipment for its function. Most of this equipment received the generic prefix FuG, meaning "radio equipment". During the war, Germany renumbered their radars. From using the year of introduction as their number they moved to a different numbering scheme.
