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. -

Ops Block Battle of Britain: Ops Block
Large print guide BATTLE OF BRITAIN Ops Block Battle of Britain: Ops Block This Operations Block (Ops Block) was the most important building on the airfield during the Battle of Britain in 1940. From here, Duxford’s fighter squadrons were directed into battle against the Luftwaffe. Inside, you will meet the people who worked in these rooms and helped to win the battle. Begin your visit in the cinema. Step into the cinema to watch a short film about the Battle of Britain. Duration: approximately 4 minutes DUXFORD ROOM Duxford’s Role The Battle of Britain was the first time that the Second World War was experienced by the British population. During the battle, Duxford supported the defence of London. Several squadrons flew out of this airfield. They were part of Fighter Command, which was responsible for defending Britain from the air. To coordinate defence, the Royal Air Force (RAF) divided Britain into geographical ‘groups’, subdivided into ‘sectors.’ Each sector had an airfield known as a ‘sector station’ with an Operations Room (Ops Room) that controlled its aircraft. Information about the location and number of enemy aircraft was communicated directly to each Ops Room. This innovative system became known as the Dowding System, named after its creator, Air Chief Marshal Sir Hugh Dowding, the head of Fighter Command. The Dowding System’s success was vital to winning the Battle of Britain. Fighter Command Group Layout August 1940 Duxford was located within ‘G’ sector, which was part of 12 Group. This group was primarily responsible for defending the industrial Midlands and the north of England, but also assisted with the defence of the southeast as required. -
Doolittle and Eaker Said He Was the Greatest Air Commander of All Time
Doolittle and Eaker said he was the greatest air commander of all time. LeMayBy Walter J. Boyne here has never been anyone like T Gen. Curtis E. LeMay. Within the Air Force, he was extraordinarily successful at every level of com- mand, from squadron to the entire service. He was a brilliant pilot, preeminent navigator, and excel- lent bombardier, as well as a daring combat leader who always flew the toughest missions. A master of tactics and strategy, LeMay not only played key World War II roles in both Europe and the Pacific but also pushed Strategic Air Command to the pinnacle of great- ness and served as the architect of victory in the Cold War. He was the greatest air commander of all time, determined to win as quickly as possible with the minimum number of casualties. At the beginning of World War II, by dint of hard work and train- ing, he was able to mold troops and equipment into successful fighting units when there were inadequate resources with which to work. Under his leadership—and with support produced by his masterful relations with Congress—he gained such enor- During World War II, Gen. Curtis E.

Canadian Airmen Lost in Wwii by Date 1943
CANADA'S AIR WAR 1945 updated 21/04/08 January 1945 424 Sqn. and 433 Sqn. begin to re-equip with Lancaster B.I & B.III aircraft (RCAF Sqns.). 443 Sqn. begins to re-equip with Spitfire XIV and XIVe aircraft (RCAF Sqns.). Helicopter Training School established in England on Sikorsky Hoverfly I helicopters. One of these aircraft is transferred to the RCAF. An additional 16 PLUTO fuel pipelines are laid under the English Channel to points in France (Oxford). Japanese airstrip at Sandakan, Borneo, is put out of action by Allied bombing. Built with forced labour by some 3,600 Indonesian civilians and 2,400 Australian and British PoWs captured at Singapore (of which only some 1,900 were still alive at this time). It is decided to abandon the airfield. Between January and March the prisoners are force marched in groups to a new location 160 miles away, but most cannot complete the journey due to disease and malnutrition, and are killed by their guards. Only 6 Australian servicemen are found alive from this group at the end of the war, having escaped from the column, and only 3 of these survived to testify against their guards. All the remaining enlisted RAF prisoners of 205 Sqn., captured at Singapore and Indonesia, died in these death marches (Jardine, wikipedia). On the Russian front Soviet and Allied air forces (French, Czechoslovakian, Polish, etc, units flying under Soviet command) on their front with Germany total over 16,000 fighters, bombers, dive bombers and ground attack aircraft (Passingham & Klepacki). During January #2 Flying Instructor School, Pearce, Alberta, closes (http://www.bombercrew.com/BCATP.htm). -

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. -
