THE RADAR WAR Forward
THE RADAR WAR by Gerhard Hepcke Translated into English by Hannah Liebmann Forward The backbone of any military operation is the Army. However for an international war, a Navy is essential for the security of the sea and for the resupply of land operations. Both services can only be successful if the Air Force has control over the skies in the areas in which they operate. In the WWI the Air Force had a minor role. Telecommunications was developed during this time and in a few cases it played a decisive role. In WWII radar was able to find and locate the enemy and navigation systems existed that allowed aircraft to operate over friendly and enemy territory without visual aids over long range. This development took place at a breath taking speed from the Ultra High Frequency, UHF to the centimeter wave length. The decisive advantage and superiority for the Air Force or the Navy depended on who had the better radar and UHF technology. 0.0 Aviation Radio and Radar Technology Before World War II From the very beginning radar technology was of great importance for aviation. In spite of this fact, the radar equipment of airplanes before World War II was rather modest compared with the progress achieved during the war. 1.0 Long-Wave to Short-Wave Radiotelegraphy In the beginning, when communication took place only via telegraphy, long- and short-wave transmitting and receiving radios were used. 2.0 VHF Radiotelephony Later VHF radios were added, which made communication without trained radio operators possible. 3.0 On-Board Direction Finding A loop antenna served as a navigational aid for airplanes. -
World War II
World War II. – “The Blitz“ This information report describes the events of “The Blitz” during the Second World War in London. The attacks between 7th September 1940 and 10 th May 1941 are known as “The Blitz”. The report is based upon information from http://www.secondworldwar.co.uk/ , http://www.worldwar2database.com/ and http://en.wikipedia.org/wiki/The_Blitz . Prelude to the War in London The Second World War started on 1 st September 1939 with the German attack on Poland. The War in London began nearly one year later. On 24 th August 1940 the German Air Force flew an attack against Thames Haven, whereby some German bombers dropped bombs on London. At this time London was not officially a target of the German Air Force. As a return, the Royal Air Force attacked Berlin. On 5th September 1940 Hitler ordered his troops to attack London by day and by night. It was the beginning of the Second World War in London. Attack on Thames Haven in 1940 The Attacks First phase The first phase of the Second World War in London was from early September 1940 to mid November 1940. In this first phase of the Second World War Hitler achieved great military success. Hitler planned to destroy the Royal Air Force to achieve his goal of British invasion. His instruction of a sustainable bombing of London and other major cities like Birmingham and Manchester began towards the end of the Battle of Britain, which the British won. Hitler ordered the German Air Force to switch their attention from the Royal Air Force to urban centres of industrial and political significance. -

Western Europe 1939-1945: Invasion
WESTERN EUROPE 1939-1945: INVASION INVASION: TASK INSTRUCTIONS The key question: How worried was Britain about invasion 1940-41? Your task In this investigation your task is to study the sources in this box. Decide how worried you think the British government was at the time for each source. You can use a colour code to indicate the extent of the threat (the US government uses this scale today). Use the table to record your views. How worried was Britain about invasion 1940-41? This drawing suggests Britain was confident that Hitler would never be able to invade. But was this just a brave front? This image is a piece of propaganda produced by the British government in the summer of 1940. The basic message is that Hitler is "all talk" and that Britain will easily drive him back if he tries to invade. A caption would have been added later. The question for us in this investigation is whether the British government really was this confident. Look at the other documents here and decide for yourself. http://www.nationalarchives.gov.uk/education/ Page 1 WESTERN EUROPE 1939-1945: INVASION A drawing produced by the British Ministry of Information in the early stages of the war Catalogue ref: INF 3/1436 Source a http://www.nationalarchives.gov.uk/education/ Page 2 WESTERN EUROPE 1939-1945: INVASION Source b What is this source? An artist working for the British Ministry of Information during the war produced this drawing. It might have been used for pamphlets, magazines or posters. The Ministry of Information published thousands of pieces of propaganda during the war. -

This paper comprises a brief history of the origins and early development of radar meteorology. Therefore, it will cover the time period from a few years before World War II through about the 1970s. The earliest developments of radar meteorology occurred in England, the United States, and Canada. Among these three nations, however, most of the first discoveries and developments were made in England. With the exception of a few minor details, it is there where the story begins. Even as early as 1900, Nicola Tesla wrote of the potential for using waves of a frequency from the radio part of the electromagnetic spectrum to detect distant objects. Then, on 11 December 1924, E. V. Appleton and M.A.F. Barnett, two Englishmen, used a radio technique to determine the height of the ionosphere using continuous wave (CW) radio energy. This was the first recorded measurement of the height of the ionosphere using such a method, and it got Appleton a Nobel Prize. However, it was Merle A. Tuve and Gregory Breit (the former of Johns Hopkins University, the latter of the Carnegie Institution), both Americans, who six months later – in July 1925 – did the same thing using pulsed radio energy. This was a simpler and more direct way of doing it. As the 1930s rolled on, the British sensed that the next world war was coming. They also knew they would be forced to defend themselves against the German onslaught. Knowing they would be outmanned and outgunned, they began to search for solutions of a technological variety. This is where Robert Alexander Watson Watt – a Scottish physicist and then superintendent of the Radio Department at the National Physical Laboratory in England – came into the story. -

I served the final 15months of my compulsory period of National Service at this, the last of my six postings. On demob, I stayed in the area and have been here ever since. I have kept in contact with four of my former colleagues. Photos and memories come out for an airing every so often, but it is only in the last few years, however, that I have started to think seriously about the history of RAF Truleigh Hill. The radar operation started in 1940, just before The Battle of Britain, and continued in several different formats until closure in 1958. -
{DOWNLOAD} Fighter: the True Story of the Battle of Britain
FIGHTER: THE TRUE STORY OF THE BATTLE OF BRITAIN PDF, EPUB, EBOOK Len Deighton | 360 pages | 27 Feb 2014 | HarperCollins Publishers | 9780007531189 | English | London, United Kingdom Fighter: The True Story of the Battle of Britain - Len Deighton - Google Libri The German "Blitzkrieg" moved swiftly to the west and the south, splitting the British and French defenders, trapping the British army at Dunkirk and forcing its evacuation from continental Europe. The British now stood alone, awaiting Hitler's inevitable attempt to invade and conquer their island. Great Britain was in trouble. The soldiers rescued from Dunkirk were exhausted by their ordeal. Worse, most of their heavy armaments lay abandoned and rusting on the French beaches. After a short rest, the Germans began air attacks in early summer designed to seize mastery of the skies over England in preparation for invasion. All that stood between the British and defeat was a small force of RAF pilots outnumbered in the air by four to one. Day after day the Germans sent armadas of bombers and fighters over England hoping to lure the RAF into battle and annihilate the defenders. Day after day the RAF scrambled their pilots into the sky to do battle often three, four or five times a day. Their words bring the events they had witnessed just hours before to life in a way no modern commentary could. The Battle of Britain Combat Archive brings the colour back with dozens of specially commissioned artworks and profiles of the aircraft. Artist Mark Postlethwaite has designed a full colour format to make each page and table easy to understand. -

The project is organised in five parts and covers the newspapers in chronological sequence. Part 1 provides full coverage for 1939; Part 2: 1940; Part 3: 1941; Part 4: 1942-1943; and finally, Part 5 covers 1944-1945. At last social historians and students of journalism can consult complete war-time runs of Britain’s popular newspapers in their libraries. Less august than the papers of record, it is these papers which reveal most about the impact of the war on the home front, the way in which people amused themselves in the face of adversity, and the way in which public morale was kept high through a mixture of propaganda and judicious reporting. Most importantly, it is through these papers that we can see how most ordinary people received news of the war. For, with a combined circulation of over 23 million by 1948, and a secondary readership far in excess of these figures, the News of the World, The People, the Daily Express, The Daily Mirror, and the Sunday Express reached into the homes of the majority of the British public and played a critical role in shaping public perceptions of the war.
