Johannes Plendl
Johannes "Hans" Plendl (6 December 1900 – 10 May 1991), German radar pioneer, was the scientist whose airplane navigation inventions made possible the early German bombing successes in World War II. Early life Plendl was born in 1900 in Munich, German Empire to parents from Northern Bavaria. His surname is most likely a truncated Bavarian dialect form of "Plendlein." Plendl served briefly in the Imperial German Navy during World War I. Shortly thereafter, Plendl began his career as a radio and beam engineer for Telefunken corporation. His early research into meter-wave propagation and radar beams necessitated additional names for newly discovered levels of the Earth's atmosphere, and Plendl is generally credited with coining the term ionosphere. In the early 1930s, he worked on developing the radio communications used in flights by civilian aircraft and the Hindenburg Zeppelin. His research and developments with the Lorenz beam landing system gave birth to what is now know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peenemünde
Peenemünde (, en, " Peene iverMouth") is a municipality on the Baltic Sea island of Usedom in the Vorpommern-Greifswald district in Mecklenburg-Vorpommern, Germany. It is part of the ''Amt'' (collective municipality) of Usedom-Nord. The community is known for the Peenemünde Army Research Center, where the world's first functional large-scale liquid-propellant rocket, the V-2, was developed. Geography The village with its seaport is located on the westernmost extremity of a long sand-spit, where the Peene empties into the Baltic Sea, in the northwestern part of Usedom Island. To the southeast it borders on the sea resort of Karlshagen. Peenemünde harbour can be reached by ferry boat across the Peene from Kröslin, liners also run along the Baltic coast to Rügen Island.

Operation Paperclip
Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from the former Nazi Germany to the U.S. for government employment after the end of World War II in Europe, between 1945 and 1959. Conducted by the Joint Intelligence Objectives Agency (JIOA), it was largely carried out by special agents of the U.S. Army's Counterintelligence Corps (CIC). Many of these personnel were former members and some were former leaders of the Nazi Party. In February 1945, Supreme Headquarters Allied Expeditionary Force (SHAEF) set up T-Force, or Special Sections Subdivision, which grew to over 2,000 personnel by June. T-Force examined 5,000 German targets with a high priority on synthetic rubber and oil catalysts, new designs in armored equipment, V-2 (rocket) weapons, jet and rocket propelled aircraft, naval equipment, field radios, secret writing chemicals, aero medicine research, gliders, and "scienti ...

Chaff (radar Countermeasure)
Chaff, originally called Window by the British and ''Düppel'' by the Second World War era German Luftwaffe (from the Berlin suburb where it was first developed), is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns, in order to confuse and distract. Modern armed forces use chaff (in naval applications, for instance, using short-range SRBOC rockets) to distract radar-guided missiles from their targets. Most military aircraft and warships have chaff dispensing systems for self-defense. An intercontinental ballistic missile may release in its midcourse phase several independent warheads as well as penetration aids such as decoy balloons and chaff. Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared t ...

Abraham Esau
Robert Abraham Esau (7 June 1884 – 12 May 1955) was a German physicist. After receipt of his doctorate from the University of Berlin, Esau worked at Telefunken, where he pioneered very high frequency (VHF) waves used in radar, radio, and television, and he was president of the ''Deutscher Telefunken Verband''. During World War I, he was a prisoner of war of the French; he was repatriated to Germany in 1919. In 1925, he was appointed professor at the University of Jena, where he also served as rector. From 1933, Esau was the State Councilor in Thuringia. From 1937, Esau was head of the physics section of the newly created Reich Research Council (RFR). From 1939, he was a professor at the University of Berlin and president of the Reich Physical and Technical Institute. From his position in the RFR, he initiated the first meeting of the Uranium Club in early 1939, the precursor to the Army Ordnance Office (HWA) German nuclear energy project, which began in September of that year ...

Hermann Göring
Hermann Wilhelm Göring (or Goering; ; 12 January 1893 – 15 October 1946) was a German politician, military leader and convicted war criminal. He was one of the most powerful figures in the Nazi Party, which ruled Germany from 1933 to 1945. A veteran World War I fighter pilot ace, Göring was a recipient of the ("The Blue Max"). He was the last commander of ''Jagdgeschwader'' 1 (Jasta 1), the fighter wing once led by Manfred von Richthofen. An early member of the Nazi Party, Göring was among those wounded in Adolf Hitler's failed Beer Hall Putsch in 1923. While receiving treatment for his injuries, he developed an addiction to morphine which persisted until the last year of his life. After Hitler became Chancellor of Germany in 1933, Göring was named as minister without portfolio in the new government. One of his first acts as a cabinet minister was to oversee the creation of the Gestapo, which he ceded to Heinrich Himmler in 1934. Following the establishment of th ...

Battle Of The Beams
The Battle of the Beams was a period early in the Second World War when bombers of the German Air Force ('' Luftwaffe'') used a number of increasingly accurate systems of radio navigation for night bombing in the United Kingdom. British scientific intelligence at the Air Ministry fought back with a variety of their own increasingly effective means, involving jamming and deception signals. The period ended when the Wehrmacht moved their forces to the East in May 1941, in preparation for the attack on the Soviet Union. The idea of "beam" based navigation was developed during the 1930s, initially as a blind landing aid. The basic concept is to produce two directional radio signals that are aimed slightly to the left and right of a runway's midline. Radio operators in the aircraft listen for these signals and determine which of the two beams they are flying in. This is normally accomplished by sending Morse code signals into the two beams, to identify right and left. For bombi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Battle Of Britain
''The Battle of Britain'' was the fourth of Frank Capra's ''Why We Fight'' series of seven propaganda films, which made the case for fighting and winning the Second World War. It was released in 1943 and concentrated on the German bombardment of the United Kingdom in anticipation of Operation Sea Lion, the planned German invasion. Plot The narrator describes the fall of France, which leaves Britain almost defenceless. British forces are vastly outnumbered, but the British people are calm. The narrator explains that is because in a democracy, the people as a whole are involved in the decision to fight. Hitler's masterplan to subjugate Britain is described. Hitler begins by attacking convoys and ports but fails to destroy them. The RAF is outnumbered "6 - 8 - 10 to one" but knocks out far more planes than the Germans do. Also, bailed-out British pilots can return to the air, but German pilots are lost. Unlike the Dutch and Polish Air Forces, Britain does not "make the mistake o ...
