Wasserfall Missile
The ("Waterfall remote-controlled anti-aircraft rocket") was a German guided supersonic surface-to-air missile project of World War II. Development was not completed before the end of the war and it was not used operationally. The system was based on many of the technologies developed for the V-2 rocket program, including the rocket itself, which was essentially a much scaled-down version of the V-2 airframe. Significant additional development was required, including design and test of an effective guidance system to allow interception of an air target, adoption of hypergolic fuels to allow the missile to stand ready for launch for days or weeks, and the development of a reliable Proximity Fuse. :234 Technical characteristics was essentially an anti-aircraft development of the V-2 rocket, sharing the same general layout and shaping. Since the missile had to fly only to the altitudes of the attacking bombers, and needed a far smaller warhead to destroy these, it could be ...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...

Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheintochter
''Rheintochter'' was a German surface-to-air missile developed by Rheinmetall-Borsig during World War II. Its name comes from the mythical ''Rheintöchter'' (Rhinemaidens) of Richard Wagner's opera series ''Der Ring des Nibelungen''. The missile was a multi-stage solid fuelled rocket.Christopher, p.131. It had four small varnished plywood control surfaces, resembling paddles, in the nose, six fins at the after end of the top stage, and four at the end of the main stage. It stood tall, with a diameter of . The sustainer motor, located ahead of the warhead (rather than behind, as is more usual) exhausted through six venturis between the first stage fins. History ''Rheintochter'' was ordered in November 1942 by the German army ( ''Heer''). Starting in August 1943, 82 test firings were made. An air-launched version was also designed. The operational version was intended to be fired from a ramp or converted gun mount. The project was cancelled on 6 February 1945. Examples are ...

Enzian
The Enzian was a German WWII surface-to-air anti-aircraft missile that was the first to use a radio controlled guidance system. During the missile's development in the late stages of the war it was plagued by organisational problems and was cancelled before becoming operational. It was named for a genus of mountain flower, in English the Gentian. Development As early as 1943 it was becoming clear that Messerschmitt's Me 163 interceptor would be difficult to use in combat. After flying to the altitude of allied bombers, it had only a few minutes to find them and make an attack before running out of fuel. Even if the aircraft did accomplish this, it then had the additional problem of lacking a weapon that could be aimed effectively while closing on the target at some . Dr. Herman Wurster of Messerschmitt proposed an answer in the form of ''Flak Rakete 1'' (FR-1) in 1943. Instead of tracking down the planes, the rocket would fly just in front of the target and then detona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reich Minister Of Armaments And War Production
The Reich Ministry of Armaments and War Production () was established on March 17, 1940, in Nazi Germany. Its official name before September 2, 1943, was the 'Reichsministerium für Bewaffnung und Munition' (). Its task was to improve the supply of the Wehrmacht with the necessary supplies of weapons and ammunition.

Inside The Third Reich
''Inside the Third Reich'' (, "Memories") is a memoir written by Albert Speer, the Nazi Minister of Armaments from 1942 to 1945, serving as Adolf Hitler's main architect before this period. It is considered to be one of the most detailed descriptions of the inner workings and leadership of Nazi Germany, but is controversial because of Speer's lack of discussion of Nazi atrocities and questions regarding his degree of awareness or involvement with them. At the Nuremberg Trials, Speer was sentenced to 20 years in prison for his use of prisoners in the armaments factories while Minister of Armaments. From 1946 to 1966, while serving the sentence in Spandau Prison, he penned more than 2,000 manuscript pages of personal memoirs. His first draft was written from March 1953 to 26 December 1954. After his release on 1 October 1966, he used Federal Archive documents to rework the material into his autobiography. He was aided editorially by Wolf Jobst Siedler, Ullstein and Propylaen, ...

Carl Krauch
Carl Krauch (7 April 1887 – 3 February 1968) was a German chemist, industrialist and Nazi war criminal. He was an executive at BASF (later IG Farben); during World War II, he was chairman of the supervisory board. He was a key implementer of the Reich's Four-Year Plan to achieve national economic self-sufficiency and promote industrial production. He was Plenipotentiary of Special Issues in Chemical Production, a senator of the Kaiser Wilhelm Society, and an honorary professor at the University of Berlin. He was convicted in the IG Farben trial after World War II and sentenced to six years in prison. Education From 1906 to 1912, Krauch studied at the ''University of Giessen'' and the '' Ruprecht-Karls-Universität Heidelberg''. From 1911 to 1912, he was an unpaid teaching assistant to R. Stallé at Heidelberg. He received his doctorate in 1912 under Theodor Curtius at Heidelberg.Hentschel and Hentschel, 1996, Appendix F; see the entry for Krauch. Career From 1912, Krauch wa ...

Albert Speer
Berthold Konrad Hermann Albert Speer (; ; 19 March 1905 – 1 September 1981) was a German architect who served as Reich Ministry of Armaments and War Production, Minister of Armaments and War Production in Nazi Germany during most of World War II. A close friend and ally of Adolf Hitler, he was convicted at the Nuremberg trials and sentenced to 20 years in prison. An architect by training, Speer joined the Nazi Party in 1931. His architectural skills made him increasingly prominent within the Party, and he became a member of Hitler's inner circle. Hitler commissioned him to design and construct structures, including the Reich Chancellery and the Nazi Party Rally Grounds, Nazi Party rally grounds in Nuremberg. In 1937, Hitler appointed Speer as General Building Inspector for Berlin. In this capacity he was responsible for the Central Department for Resettlement that Nazi persecution of Jews, evicted Jewish tenants from their homes in Berlin. In February 1942, Speer was a ...

Sweden During World War II
Sweden maintained its policy of neutrality during World War II. When the war began on 1 September 1939, the fate of Sweden was unclear. But by a combination of its geopolitical location in the Scandinavian Peninsula, ''realpolitik'' maneuvering during an unpredictable course of events, and a dedicated military build-up after 1942, Sweden kept its official neutrality status throughout the war. At the outbreak of hostilities, Sweden had held a neutral stance in international relations for more than a century, since the end of the Napoleonic Wars in 1814 and the invasion of Norway. At the outbreak of war in September 1939, twenty European nations were neutral. Sweden was one of only nine of these nations to maintain this stance for the remainder of the war, along with Ireland, Portugal, Spain, Switzerland, and the microstates of Andorra, Liechtenstein, Vatican City, and San Marino. The Swedish Government made a few concessions, and sometimes breached the nation's neutrality in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsonic Flight
Aerodynamics () is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for the development of ...

Operation Crossbow
''Crossbow'' was the code name in World War II for Anglo-American operations against the German V-weapons, long range reprisal weapons (V-weapons) programme. The primary V-weapons were the V-1 flying bomb and V-2 rocket, which were launched against Britain from 1944 to 1945 and used against continental European targets as well. Initial intelligence investigations in 1943 into the progress of German long range weapons were carried out under the code name Bodyline. On 15 November, a larger operation was set up under the name ''Crossbow''. Post-war, Crossbow operations became known as "Operation Crossbow" particularly following the Operation Crossbow (film), 1965 film of the same name. Crossbow included strategic operations against research and development of the weapons, their manufacture, transportation and attacks on their launch site, and fighter intercepts against missiles in flight. At one point, the British government, in near panic, demanded that upwards of 40% of bomber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Hydra (1943)
Operation Hydra was an attack by RAF Bomber Command on a German scientific research centre at Peenemünde on the night of 17/18 August 1943. Group Captain John Searby, commanding officer of No. 83 Squadron RAF, commanded the operation, the first time that Bomber Command used a master bomber to direct the attack of the main force. Hydra was the first operation against the German V-weapon programme, a campaign later known as "Crossbow". The British lost 40 bombers and 215 aircrew, and several hundred enslaved workers in the nearby Trassenheide forced labour camp were killed. The ''Luftwaffe'' lost twelve night-fighters and about 170 German civilian personnel were killed, including two V-2 rocket scientists. Assessments of the raids effectiveness vary; the United States Strategic Bombing Survey (1945) called the raid "not effective", while in 2006 the historian Adam Tooze judged that it had been highly successful.
