Plotter (RAF)
Plotters were employed on an early form of air traffic monitoring that played a vital role in World War II, particularly during the Battle of Britain, The Blitz and the bombing of British cities that followed. They worked at individual RAF stations' Sector Control Rooms or in the central Group Control Rooms that directed the operations of RAF fighters. The majority of plotters were female, members of the Women's Auxiliary Air Force (WAAFs). History Captain Philip Edward Broadley Fooks transferred from the Royal Garrison Artillery to the Anti-Aircraft Defences, Home Forces in June 1918 and he suggested displaying the latest information graphically on a large horizontal map at central London control near Horse Guards in Spring Gardens. This map was marked with a grid upon which different-shaped and annotated pieces representing the airborne forces were colour coded to the clocks to distinguish fresh from older information and were manipulated with wooden rakes by operators guided ...

The Operations Room At RAF Fighter Command's No
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Britain
The Battle of Britain, also known as the Air Battle for England (german: die Luftschlacht um England), was a military campaign of the Second World War, in which the Royal Air Force (RAF) and the Fleet Air Arm (FAA) of the Royal Navy defended the United Kingdom (UK) against large-scale attacks by Nazi Germany's air force, the Luftwaffe. It was the first major military campaign fought entirely by air forces."92 Squadron – Geoffrey Wellum." ''Battle of Britain Memorial Flight'' via ''raf.mod.uk.''. Retrieved: 17 November 2010, archived 2 March 2009. The British officially recognise the battle's duration as being from 10 July until 31 October 1940, which overlaps the period of large-scale night attacks known as |
The Blitz
The Blitz was a German bombing campaign against the United Kingdom in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term , the German word meaning 'lightning war'. The Germans conducted mass air attacks against industrial targets, towns, and cities, beginning with raids on London towards the end of the Battle of Britain in 1940 (a battle for daylight air superiority between the Luftwaffe and the Royal Air Force over the United Kingdom). By September 1940, the Luftwaffe had lost the Battle of Britain and the German air fleets () were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.Price 1990, p. 12. Adolf Hitler and Reichsmarschall Hermann Göring, commander-in-chief of the Luftwaffe, ordered the new policy on 6 September 1940. From 7 September 1940, London was systematically bombed by the Luftwaffe for 56 of the following 57 days and nights. Most notable was a large dayligh ...

Women's Auxiliary Air Force
The Women's Auxiliary Air Force (WAAF), whose members were referred to as WAAFs (), was the female auxiliary of the Royal Air Force during World War II. Established in 1939, WAAF numbers exceeded 180,000 at its peak strength in 1943, with over 2,000 women enlisting per week. History A Women's Royal Air Force had existed from 1918 to 1920. The WAAF was created on 28 June 1939, absorbing the forty-eight RAF companies of the Auxiliary Territorial Service which had existed since 1938. Conscription of women did not begin until 1941. It only applied to those between 20 and 30 years of age and they had the choice of the auxiliary services or factory work. Women recruited into the WAAF were given basic training at one of five sites, though not all of the sites ran training simultaneously. The five sites were at West Drayton, Harrogate, Bridgnorth, Innsworth and Wilmslow. All WAAF basic recruit training was located at Wilmslow from 1943. WAAFs did not serve as aircrew.

Royal Garrison Artillery
The Royal Garrison Artillery (RGA) was formed in 1899 as a distinct arm of the British Army's Royal Regiment of Artillery serving alongside the other two arms of the Regiment, the Royal Field Artillery (RFA) and the Royal Horse Artillery (RHA). The RGA were the 'technical' branch of the Royal Artillery who were responsible for much of the professionalisation of technical gunnery that was to occur during the First World War. It was originally established to man the guns of the British Empire's forts and fortresses, including coastal artillery batteries, the heavy gun batteries attached to each infantry division and the guns of the siege artillery. The RGA was amalgamated with the RFA in 1924, from which time the only two arms within the Royal Regiment of Artillery have been the Royal Artillery and the Royal Horse Artillery. Organisation The Royal Garrison Artillery came into existence as a separate entity when existing coastal defence, mountain, siege and heavy batteries of t ...

Spring Gardens
Spring Gardens is a dead-end street at the south east extreme of St. James's, London, England, that crosses the east end of The Mall between Admiralty Arch and Trafalgar Square. Part of the old liberty of Westminster and the current City of Westminster, it abuts Whitehall, Horse Guards Parade, Green Park, and the Charing Cross/Strand/Trafalgar Square locality. It is named after the gardens that stood here. These featured a decorative fountain in the time of Elizabeth I that was set in motion by passers-by treading on hidden machinery, knowingly or unknowingly. Mostly Victorian buildings have been built lining the street. Occupants The Whig playwright and poet Susanna Centlivre (c.1669 – 1723), who has been described as "the most successful female playwright of the eighteenth century", spent the end of her life here, and wrote her most famous work ''A Bold Stroke for a Wife'' at her home at the corner of Buckingham Court, Spring Gardens, in 1718.''Literary Landmarks of Lond ...

Acoustic Location
Acoustic location is the use of sound to determine the distance and direction of its source or reflector. Location can be done actively or passively, and can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the earth). * ''Active'' acoustic location involves the creation of sound in order to produce an echo, which is then analyzed to determine the location of the object in question. * ''Passive'' acoustic location involves the detection of sound or vibration created by the object being detected, which is then analyzed to determine the location of the object in question. Both of these techniques, when used in water, are known as sonar; passive sonar and active sonar are both widely used. Acoustic mirrors and dishes, when using microphones, are a means of passive acoustic localization, but when using speakers are a means of active localization. Typically, more than one device is used, and the location is then triangulated between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Royal Observer Corps
The Royal Observer Corps (ROC) was a civil defence organisation intended for the visual detection, identification, tracking and reporting of aircraft over Great Britain. It operated in the United Kingdom between 29 October 1925 and 31 December 1995, when the Corps' civilian volunteers were stood down (ROC headquarters staff at RAF Bentley Priory stood down on 31 March 1996). Composed mainly of civilian spare-time volunteers, ROC personnel wore a Royal Air Force (RAF) style uniform and latterly came under the administrative control of RAF Strike Command and the operational control of the Home Office. Civilian volunteers were trained and administered by a small cadre of professional full-time officers under the command of the Commandant Royal Observer Corps; latterly a serving RAF Air Commodore. Overview In 1925, following a Defence Committee initiative undertaken the previous year, the formation of an RAF command concerning the Air Defence of Great Britain led to the provis ...

Filter Room
A Filter Room was part of RAF Fighter Command's radar defence system in Britain during the Second World War. The filter room at Fighter Command Headquarters lay at the top of the Dowding system - the integrated ground-controlled interception network that covered the United Kingdom. The operations were considered secret and, as such, were covered by the Official Secrets Act. Operation When the radar defence of Great Britain was set up, Robert Watson-Watt and his team created a chain of radar stations around the coastline. The stations were named Chain Home (CH). Radar detection of objects at that time was at its early stages of development and there was a need for a method to combine the different radar information gathered from different stations. Accurate details of incoming or outgoing aircraft were obtained by combining overlapping reports from adjacent radar stations and then collating and correcting them. This process of combining information was called "filtering" and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Len Deighton
Leonard Cyril Deighton (; born 18 February 1929) is a British author. His publications have included cookery books, history and military history, but he is best known for his spy novels. After completing his national service in the Royal Air Force, Deighton attended art school in London, and graduated from the Royal College of Art in 1955. He had several jobs before becoming a book and magazine illustrator—including designing the cover for first UK edition of Jack Kerouac's 1957 work ''On the Road''. He also worked for a period in an advertising agency. During an extended holiday in France he wrote his first novel, ''The IPCRESS File'', which was published in 1962, and was a critical and commercial success. He wrote several spy novels featuring the same central character, a working-class intelligence officer, cynical and tough. Between 1962 and 1966 Deighton was the food correspondent for ''The Observer'' and drew cookstrips—black and white graphic recipes with a limited nu ...
