No. 11 Group RAF
No. 11 Group is a group in the Royal Air Force first formed in 1918. It had been formed and disbanded for various periods during the 20th century before disbanding in 1996 and reforming again in 2018. Its most famous service was in 1940 in the Battle of Britain during the Second World War, when it defended London and the south-east of the United Kingdom from attacks by the German ''Luftwaffe''. It was reformed in late 2018 as a "multi-domain operations group" to ensure the service thinks and acts in a networked way. History First World War No. 11 Group was first formed on 1 April 1918 in No. 2 Area as No. 11 (Equipment) Group, and was transferred to South-Western Area the next month on 8 May. The Group was disbanded on 17 May 1918. Inter-war years The next incarnation of the Group occurred in 22 August 1918 when it was formed as part of the North-Western Area. On 6 February 1920, Group captain Ian Bonham-Carter took command and three months later, in May 1920, 11 Group was r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heraldic Badges Of The Royal Air Force
Heraldic badges of the Royal Air Force are the insignia of certain commands, squadrons, units, wings, groups, branches and stations within the Royal Air Force. They are also commonly known as crests, especially by serving members of the Royal Air Force, but officially they are badges. Each badge must be approved by the reigning monarch of the time, and as such will either have a Tudor Crown (heraldry), King's or St Edward's Crown, Queen's Crown upon the top of the badge, dependent upon which monarch granted approval and the disbandment date of the unit.Most units/squadrons and bases had their badges updated to the Queen's Crown sometime after her accession, (although in some cases many years elapsed before the badge was updated). Most of the flying units were disbanded after the Second World War, so their badges retained the King's Crown. Queen Elizabeth II promulgated an order in October 1954 detailing that all current badges in use, and from that date on, were to use the Queen's ...

Group (military Unit)
A group is a military unit or a military formation that is most often associated with military aviation. Air and aviation groups The terms group and wing differ significantly from one country to another, as well as between different branches of a national defence force. Air groups vary considerably in size and status, but generally take two forms: * A unit of two to four squadrons, commanded by a lieutenant colonel, colonel, commander, naval captain or an equivalent rank. The United States Air Force (USAF), ''groupes'' of the French ''Armée de l'air'', ''gruppen'' of the German ''Luftwaffe'', United States Marine Corps Aviation, British Fleet Air Arm and some other naval air services usually follow this pattern. * A larger formation, often comprising more than 10 squadrons, commanded by a major general, brigadier general, commodore, rear admiral, air commodore or air vice-marshal. The air forces of many Commonwealth countries, such as the British Royal Air Force (RAF), foll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plotting Table
A plotting board was a mechanical device used by the U.S. Army Coast Artillery Corps as part of their fire control system to track the observed course of a target (typically a moving ship), project its future position, and derive the uncorrected data on azimuth (or direction) and range needed to direct the fire of the guns of a battery to hit that target. Plotting boards of this sort were first employed by the Coast Artillery around 1905, and were the primary means of calculating firing data until WW2. Towards the end of WW2 these boards were largely replaced by radar and electro-mechanical gun data computers, and were relegated to a back-up role. Although several different types of plotting boards were used by the Coast Artillery over the years, the example described here is the Whistler- Hearn Plotting Board, Model of 1904 which was widely employed by the Coast Artillery between about 1905 and 1925. This description is primarily derived from two manuals of the period, each of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Britain Bunker
The Battle of Britain Bunker is an underground operations room at RAF Uxbridge, formerly used by No. 11 Group Fighter Command during the Second World War. Fighter aircraft operations were controlled from there throughout the War but most notably during the Battle of Britain and on D-Day. Today it is run by Hillingdon Council as a heritage attraction with attached museum. A new visitor centre above ground opened in March 2018. The Bunker is located at RAF Uxbridge, not far from Uxbridge town centre and Uxbridge Underground station. Background As the location of No. 11 Group RAF's Operations Room, The Battle of Britain Bunker was one of the key parts of the world's first integrated air defence system. Often known as the "Dowding system" (after Air Chief Marshal Sir Hugh Dowding, Commander-in-Chief Fighter Command at the time of installation), the system linked Fighter Command with Anti-Aircraft Command, Barrage Balloon Command, the Observer Corps, Chain Home Radio Direction F ...

London Borough Of Hillingdon
The London Borough of Hillingdon () is the largest and westernmost borough in West London, England. It was formed from the districts of Hayes and Harlington, Ruislip-Northwood, Uxbridge, and Yiewsley and West Drayton in the ceremonial county of Middlesex. Today, Hillingdon is home to Heathrow Airport (which straddles the border between Hillingdon and Hounslow) and Brunel University, and is the second largest of the 32 London boroughs by area. The main towns in the borough are Hayes, Ruislip, Northwood, West Drayton and Uxbridge. Hillingdon is the second least densely populated of the London boroughs, due to a combination of large rural land in the north, RAF Northolt Aerodrome, and the large Heathrow Airport. Governance Administrative history The borough was formed in 1965 from the Hayes and Harlington Urban District, Municipal Borough of Uxbridge, Ruislip-Northwood Urban District, and Yiewsley and West Drayton Urban District, all formerly in the ceremonial county of Midd ...

RAF Uxbridge
RAF Uxbridge was a Royal Air Force (RAF) station in Uxbridge, within the London Borough of Hillingdon, occupying a site that originally belonged to the Hillingdon House estate. The British Government purchased the estate in 1915, three years before the founding of the RAF. Until the outbreak of the Second World War in 1939, the station was open to the public. The station is best known as the headquarters of No. 11 Group RAF, which was responsible for the aerial defence of London and the south-east of England during the Battle of Britain. Hillingdon House served as the group's headquarters. A bunker, subsequently known as the Battle of Britain Bunker, was built nearby to house the Operations Room, which controlled fighter squadrons operating within the group. The Operations Room was also responsible for providing air support during the evacuation of Dunkirk in May 1940 ( Operation Dynamo) and the D-Day landings (Operation Overlord). It was here that Winston Churchill fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dowding System
The Dowding system was the world's first wide-area ground-controlled interception network, controlling the airspace across the United Kingdom from northern Scotland to the southern coast of England. It used a widespread dedicated land-line telephone network to rapidly collect information from Chain Home (CH) radar stations and the Royal Observer Corps (ROC) in order to build a single image of the entire UK airspace and then direct defensive interceptor aircraft and anti-aircraft artillery against enemy targets. The system was built by the Royal Air Force just before the start of World War II, and proved decisive in the Battle of Britain. The Dowding system was developed after tests demonstrated problems relaying information to the fighters before it was out of date. Air Chief Marshal Hugh Dowding, commander of RAF Fighter Command, solved the problem through the use of hierarchical reporting chains. Information was sent to Fighter Command Headquarters (FCHQ) central ''filter room' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

RAF Fighter Command
RAF Fighter Command was one of the commands of the Royal Air Force. It was formed in 1936 to allow more specialised control of fighter aircraft. It served throughout the Second World War. It earned near-immortal fame during the Battle of Britain in 1940, when the Few held off the Luftwaffe attack on Britain. The Command continued until 17 November 1943, when it was disbanded and the RAF fighter force was split into two categories; defence and attack. The defensive force became Air Defence of Great Britain (ADGB) and the offensive force became the RAF Second Tactical Air Force. Air Defence of Great Britain was renamed back to Fighter Command in October 1944 and continued to provide defensive patrols around Great Britain. It was disbanded for the second time in 1968, when it was subsumed into the new Strike Command. Origins On 20 May 1926, the forerunner of Fighter Command was established as a group within Inland Area. On 1 June 1926, Fighting Area was transferred to the Air D ...

Group Captain
Group captain is a senior commissioned rank in the Royal Air Force, where it originated, as well as the air forces of many countries that have historical British influence. It is sometimes used as the English translation of an equivalent rank in countries which have a non-British air force-specific rank structure. Group captain has a NATO rank code of OF-5, meaning that it ranks above wing commander and immediately below air commodore, and is the equivalent of the rank of captain in the navy and of the rank of colonel in other services. It is usually abbreviated Gp Capt. In some air forces (such as the RAF, IAF and PAF), the abbreviation GPCAPT is used; in others (such as the RAAF and RNZAF), and in many historical contexts, the abbreviation G/C is used. The full phrase “group captain” is always used; the rank is never abbreviated to "captain". RAF usage ;History On 1 April 1918, the newly created RAF adopted its officer rank titles from the British Army, with Royal ...
