No. 7A Squadron RNAS
No. 214 Squadron is a former unit of the Royal Air Force. History World War I No 214 Squadron was formed from No. 14 Squadron Royal Naval Air Service (RNAS), itself formerly ''No. 7A Squadron RNAS'' only taking on the new number on 9 December 1917. With the creation of the RAF from the Royal Flying Corps and the RNAS on 1 April 1918 it received the number 214. It was later given the fuller title No 214 (Federated Malay States) Squadron. No. 214 Squadron started with the Handley Page Type O/100 bomber but soon got the more powerful O/400 in the middle of 1918 with which it continued to fly against German strategic targets. From 29 June to 23 October 1918, 214 Squadron was based at RAF Saint Inglevert. Between the Wars Post war the squadron was moved to Egypt but it was disbanded on 1 February 1920 with its crew and aircraft merged into No. 216 Squadron RAF. On 16 September 1935 'B' Flight of No. 9 Squadron RAF was used to create a new 214 Squadron. Again a bomber squadron it h ...

RAF Stradishall
Royal Air Force Stradishall or more simply RAF Stradishall is a former Royal Air Force station located north east of Haverhill, Suffolk and south west of Bury St Edmunds, Suffolk, England. Part of the site remains in use as Stradishall Training Area. History In his memoirs, Murray Peden, a Royal Canadian Air Force pilot, recounts his training at Stradishall. In the RAF's "heavy conversion unit" (No. 1657 Heavy Conversion Unit) at the airfield, he and others were trained to fly Short Stirling bombers. He describes in detail his experiences flying there, and the life on the ground of aircrew who were shortly to begin operations over Nazi Germany as part of RAF Bomber Command during World War II. The airfield was home to a number of squadrons during its lifetime: * No. 1 Squadron RAF, No. 9 Squadron RAF, No. 35 Squadron RAF, No. 51 Squadron RAF, No. 54 Squadron RAF, No. 75 Squadron RAF, No. 85 Squadron RAF, No. 89 Squadron RAF. * No. 101 Squadron RAF, No. 109 Squadron RAF ...

Lichtenstein Radar
The Lichtenstein radar was among the earliest airborne radars available to the Luftwaffe in World War II and the first one used exclusively for air interception. Developed by Telefunken, it was available in at least four major revisions, called FuG 202 Lichtenstein B/C, FuG 212 Lichtenstein C-1, FuG 220 Lichtenstein SN-2 and the very rarely used FuG 228 Lichtenstein SN-3. (FuG is short for ''Funk-Gerät'', radio set). The Lichtenstein series remained the only widely deployed airborne interception radar used by the Germans on their night fighters during the war — the competing FuG 216 through 218 ''Neptun'' mid-VHF band radar systems were meant as a potentially more versatile stop-gap system through 1944, until the microwave-based FuG 240 "Berlin" could be mass-produced; the ''Berlin'' system was still being tested when the war ended. FuG 202 Lichtenstein B/C Early FuG 202 Lichtenstein B/C units were not deployed until 1942. They operated at a maximum RF output power of ...

Bomber Stream
The bomber stream was a saturation attack tactic developed by the Royal Air Force (RAF) Bomber Command to overwhelm the nighttime German aerial defences of the Kammhuber Line during World War II. The Kammhuber Line consisted of three layers of zones of about 32 km long (north–south) and 20 km wide (east–west). In each zone there were two German night fighter aircraft receiving ground-directed guidance from their own ''Himmelbett'' controller within each zone. While the Himmelbett control center could only handle two fighters, this was adequate for dealing with the RAF Bomber Command tactic of sending its night time bombers individually, with each bomber plotting its own route to the target, to avoid flak concentrations. At the urging of British scientific military strategist R. V. Jones, Bomber Command reorganized their attacks into streams carefully positioned to fly right down the middle of a cell. The introduction of the GEE navigation system allowed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Fighter
A night fighter (also known as all-weather fighter or all-weather interceptor for a period of time after the Second World War) is a fighter aircraft adapted for use at night or in other times of bad visibility. Night fighters began to be used in World War I and included types that were specifically modified to operate at night. During the Second World War, night fighters were either purpose-built night fighter designs, or more commonly, heavy fighters or light bombers adapted for the mission, often employing radar or other systems for providing some sort of detection capability in low visibility. Many night fighters of the conflict also included instrument landing systems for landing at night, as turning on the runway lights made runways into an easy target for opposing intruders. Some experiments tested the use of day fighters on night missions, but these tended to work only under very favourable circumstances and were not widely successful. Avionics systems were greatly mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airborne Cigar
Airborne Cigar, or ABC for short, was a World War II electronic countermeasure (ECM) system developed by the Telecommunications Research Establishment (TRE) to jam ''Luftwaffe'' ground-to-air radios operating in the very high frequency (VHF) band. When used properly, the system made enemy night fighter communications almost impossible. The Germans referred to ABC as "dudelsack", German for bagpipes, in reference to the warbling sound. The system consisted of a wide-band receiver and three tunable transmitters of about 50 W output. The German-speaking Special Duties Operators (SDOs) would listen to signals in the band to determine which frequencies were being used by ground controllers. When one was found, one of the transmitters would be turned to that frequency and began broadcasting noise. ABC was operated primarily by No. 101 Squadron RAF, part of the specialist No. 100 Group RAF. As the system was only useful over a range of about , their Lancasters were spread out th ...

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures 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 counter-countermeasures can sometimes hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. 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, then introduced it into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (later, the USAAF) promoted the aircr ...

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
