Oberraderach
Raderach ( en, Raderach) was the World War II location of Prüffeld-Anlage Raderach, a V-2 rocket test facility code named "Porcelain Factory" (german: Porzellanfabrik). Raderach testing ensured V-2 turbopumps did not overpressure combustion chambers (there was no controller) and was planned for rocket motors to be installed by the nearby Zeppelin Works (german: Luftschiffbau Zeppelin GmbH) as part of the Eastern Works (V-2 facilities in the Vienna-Freidrichshafen area). Firings were visible in Switzerland across Lake Constance and testing ended shortly after the facility began operation. The first design sketches for the Raderach facility were prepared by Bernhard Tessmann of the Peenemünde Army Research Center, and Captain König was the military representative at Raderach. By mid-1942, the German Army had started construction of the Raderach motor test stand, and a nearby liquid oxygen ('' A-stoff'') plant produced up to 900 tons/month. On July 25, 1943, British V-2 intel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Of Friedrichshafen In World War II
The German city of Friedrichshafen was bombed during World War II as part of the Allied strategic bombing campaign against German war materiel industry, particularly in the targeting of German fighter aircraft production and long range missile development. Background Friedrichshafen lies in the Bodenseekreis district, on Lake Constance in the extreme south of Germany, and at the time it was at the edge of the German nightfighter defences. Targets included the ''Dornier Flugzeugwerke'' aircraft works at Manzell, the Maybach tank engine factory, the ''Luftschiffbau Zeppelin'' aircraft works and its Oberraderach test facility near Raderach, and the ''Zahnradfabrik Friedrichshafen'' (literally "gearwheel factory Friedrichshafen") tank gearbox factory. In February 1944 an underground factory at Immenstaad near Friedrichshafen was suspected to be a synthetic oil and/or liquid oxygen plant.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Code Name
A code name, call sign or cryptonym is a code word or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names. Military origins During World War I, names common to the Allies referring to nations, cities, geographical features, military units, military operations, diplomatic meetings, places, and individual persons were agreed upon, adapting pre-war naming procedures in use by the governments concerned. In the British case names were administered and controlled by the Inter Services Security Board (ISSB) staffed b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frankenthal Porcelain Factory
The Frankenthal Porcelain Factory (german: link=no, Porzellanmanufaktur Frankenthal) was one of the greatest porcelain manufacturers of Germany and operated in Frankenthal in the Rhineland-Palatinate between 1755 and 1799. From the start they made hard-paste porcelain, and produced both figurines and dishware of very high quality, somewhat reflecting in style the French origin of the business, especially in their floral painting. Initially they were a private business, but from 1761 were owned by the local ruler, like most German porcelain factories of the period. History The porcelain factory in Frankenthal was established in 1755 by the Hannong family, who had previously manufactured porcelain, as well as Strasbourg faience, in Strasbourg until Louis XVI established a state monopoly on porcelain in favour of the Sèvres factory and closed down all others. Karl Hannong transferred his business to an empty barracks in Frankenthal, just outside Mannheim, and staffed it with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftschiffbau Zeppelin
Luftschiffbau Zeppelin GmbH is a German aircraft manufacturing company. It is perhaps best known for its leading role in the design and manufacture of rigid airships, commonly referred to as ''Zeppelins'' due to the company's prominence. The name 'Luftschiffbau' is a German word meaning ''building of airships''. The company was founded by Count Ferdinand von Zeppelin in 1908 as a formal entity to continue advancing his pioneering research into rigid airships. ''Luftschiffbau Zeppelin'' became the leading manufacturer in the field of large lighter-than-air vehicles; its products were used in both military and civilian capacities. The firm founded DELAG, the world's first airline to use an aircraft in revenue service, in 1909 on the back of public interest and using its own airships. During the First World War, Zeppelins were employed as the first long distance strategic bombers, launching numerous raids upon Belgium, France, and the United Kingdom. Following Count von Zeppelin's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Constance
Lake Constance (german: Bodensee, ) refers to three Body of water, bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein, Lake Rhine (''Seerhein''). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria, the Swiss cantons of Canton of St. Gallen, St. Gallen, Canton of Thurgau, Thurgau, and Canton of Schaffhausen, Schaffhausen, and the Austrian state of Vorarlberg. The actual location of the border Lake_Constance#International_borders, is disputed. The Alpine Rhine forms in its original course the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernhard Tessmann
Bernhard Robert Tessmann (August 15, 1912 in Zingst – December 19, 1998) was a German expert in guided missiles during World War II, and later worked for the United States Army and NASA. Life Tessmann first met rocket expert Wernher von Braun in 1935. He had little interest in spaceflight, even though he had seen the sets of the film ''Frau im Mond'' since his father worked at Universum Film AG studios. Tessmann was involved in the basic planning for Army Research Center Peenemünde, moving there in late 1936 to supervise construction and conduct first engine testing there at Test Stand I. Tessmann worked on wind tunnels, then on thrust measuring systems for V-2 engines. He was evacuated after the bombing in August 1943 to Koelpinsee where he designed ground equipment for V-2 mobile units and was involved in the planning for the "Projekt Zement" underground V-2 facilities at Ebensee, Austria, and test facilities near Lehesten. Tessmann was a key man in securing the V-2 legacy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peenemünde Army Research Center
The Peenemünde Army Research Center (german: Heeresversuchsanstalt Peenemünde, HVP) was founded in 1937 as one of five military proving grounds under the German Army Weapons Office (''Heereswaffenamt''). Several German guided missiles and rockets of World War II were developed by the HVP, including the V-2 rocket. The works were attacked by the British in Operation Crossbow from August 1943, before falling to the Soviets in May 1945. History On April 2, 1936, the aviation ministry paid 750,000 reichsmarks to the town of Wolgast for the whole Northern peninsula of the Baltic island of Usedom. By the middle of 1938, the Army facility had been separated from the Luftwaffe facility and was nearly complete, with personnel moved from Kummersdorf. The Army Research Center (''Peenemünde Ost'') consisted of ''Werk Ost'' and ''Werk Süd'', while ''Werk West'' (Peenemünde West) was the Luftwaffe Test Site (), one of the four test and research facilities of the Luftwaffe, with i ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Stoffs
During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-''Stoff'' (). The following list of stoffs refers to the World War II aerospace meanings if not noted otherwise. Meaning of ''stoff'' The German word ''Stoff'' (plural ''Stoffe''), like the English word ''stuff'', derives from Old French ''estoffe'', however the meanings are somewhat different. Stoff has a fairly broad range of meanings, including "chemical substance" or "matter", "fuel" and "cloth", depending on the context. The German names of the common elements hydrogen, oxygen and nitrogen are ''Wasserstoff'', ''Sauerstoff'' and ''Stickstoff'' ("hydrogen" being a scientific Greek neologism for "constituent of water", "oxygen" for "constituent of acids", "nitrogen" for "constituent of nitre", i.e. saltpeter - although the German root ''stick-'' is derived from ''ersticken'', "to smother, suffocate", referring to its property of not supporting combustion and res ...

V-1 And V-2 Intelligence
Military intelligence on the V-1 flying bomb, V-1 and V-2 rocket, V-2 weapons developed by the Germans for attacks on the United Kingdom during the Second World War was important to countering them. Intelligence came from a number of sources and the Anglo-American intelligence agencies used it to assess the threat of the German V-weapons. The activities included use of the Double Cross System for counter-intelligence and the British (code named) "V-1 and V-2 Intelligence#Big Ben, Big Ben" project to reconstruct and evaluate German missile technology for which Denmark, Poland, Luxembourg, Sweden, and the USSR provided assistance. German counter-intelligence wiktionary:ruses, ruses were used to mislead the Allies about V-1 flying bomb facilities, V-1 launch sites and the Peenemünde Army Research Center which were Operation Crossbow, targeted for attacks by the Allies.

Aerial Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisatio ...
