V-2
The V2 (), with the technical name '' Aggregat-4'' (A4), was the world's first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a " vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the . Beginning in September 1944, more than 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from resulted in the deaths of an estimated 9,000 civilians and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wernher Von Braun
Wernher Magnus Maximilian Freiherr von Braun ( ; ; 23 March 191216 June 1977) was a German–American aerospace engineer and space architect. He was a member of the Nazi Party and '' Allgemeine SS'', the leading figure in the development of rocket technology in Nazi Germany, and later a pioneer of rocket and space technology in the United States. As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde during World War II. The V-2 became the first artificial object to travel into space on 20 June 1944. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1 in 1958. He worked with Walt Disney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-weapons
V-weapons, known in original German as (, German: "retaliatory weapons", "reprisal weapons"), were a particular set of long-range artillery weapons designed for strategic bombing during World War II, particularly strategic bombing and Aerial bombing of cities#European theatre , aerial bombing of cities. They were the V-1 flying bomb, V-1, a pulsejet-powered cruise missile; the V-2 rocket, V-2, a Liquid-propellant rocket, liquid-fueled ballistic missile; and the V-3 cannon. Nazi Germany , Germany intended to use all of these weapons in a military campaign against United Kingdom, Britain, though only the V-1 and V-2 were so used in a campaign conducted 1944–45. After the invasion of western Europe by the Allies of World War II , Allies, these weapons were also employed against targets on the mainland of Europe, mainly in France and Belgium. Strategic bombing with V-weapons killed approximately 18,000 people, mostly civilians. The cities of London, Antwerp and Liège were the ...

Mittelwerk
Mittelwerk (; German for "Central Works") was a German World War II factory built underground in the Kohnstein to avoid Allied bombing. It used slave labor from the Mittelbau-Dora concentration camp to produce V-2 ballistic missiles, V-1 flying bombs, and other weapons. Mittelwerk GmbH On the night of 17/18 August 1943, RAF bombers carried out Operation Hydra against the Peenemünde Army Research Center where V-2 development and production was being carried out. On 19 October 1943, the German limited company Mittelwerk GmbH was issued War Contract No. 0011-5565/43 by General Emil Leeb, head of the Army Weapons Office, for 12,000 A-4 missiles at 40,000 Reichsmarks each. Mittelwerk GmbH also headed sites for V-2 rocket development and testing at Schlier (Project Zement) and Lehesten. Beginning in May 1944, Georg Rickhey was the Mittelwerk general manager, Albin Sawatzki was the Mittelwerk technical director over both Arthur Rudolph's Technical Division (with deputy Ka ...

Mischgerät (V-2 Guidance Computer)
Designed in 1941 by Helmut Hölzer, the Mischgerät (mixer device) was the first fully electronic computing device, used to implement Hölzer’s V-2 rocket stability control equation during powered flight. It differentiated the voltages from the ''Vertikant'' (yaw and roll) and ''Horizont'' (pitch) gyroscopes to sense the gyro platform's divergence from its original orientation in pitch, yaw and roll, - and more crucially derived the rate of divergence - and output amplified correcting voltages to the steering servos for the exhaust vanes and external rudders. Technical concepts tested with the smaller Aggregat#A5 (1938–1942), A5 research rocket included use of the Siemens Vertikant stability control system with rate gyros. This approach didn't scale well for the larger and higher performance V-2. From his previous glider ground speed indicator concept in the mid-1930s, Hölzer realized he could implement an electrical approximation of a stability control equation by processi ...

Aggregat (rocket Family)
The ''Aggregat'' series (German for "Aggregate") was a set of ballistic missile designs developed in 1933–1945 by a research program of Nazi Germany's Army ( ''Heer''). Its greatest success was the A4, more commonly known as the V2. A1 (1933) The A1 was the first rocket design in the ''Aggregat'' series. It was designed in 1933 by Wernher von Braun at the German Army research program at Kummersdorf headed by Colonel Dr Walter Dornberger. The A1 was the grandfather of most modern rockets. The rocket was long, in diameter, and had a takeoff weight of . The engine, designed by Arthur Rudolph, used a pressure-fed rocket propellant system burning ethanol and liquid oxygen, and produced 2.9 kN (660 lbf) of thrust for 16 seconds. The LOX tank was located within the fuel tank and insulated with a fiberglass material. The rocket was stabilized by a 3 axes gyroscope system in the nose, supplied by Kreiselgeräte GmbH. The rocket could not be rotated for stability as with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peenemünde Army Research Center
The Peenemünde Army Research Center (, 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 its headquarters facility at ''Erprobungss ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere, while most larger missiles travel outside the atmosphere. The type of ballistic missile with the greatest range is an intercontinental ballistic missile (ICBM). The largest ICBMs are capable of full orbital flight. These missiles are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight and thus restricted to the atmosphere. History One modern pioneer ballistic missile was the A-4, commonly known as the V-2, developed by Nazi Germany in the 1930s and 1940s under the direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris, followed by an attack on London two ...

Meillerwagen
The ''Meillerwagen'' () was a German World War II trailer used to transport a V-2 rocket from the 'transloading point' of the Technical Troop Area to the launching point, to erect the missile on the ''Brennstand'' (), and to act as the Service tower, service gantry for fuelling and launch preparation. The unofficial 'Meillerwagen' name was often used in official documents and refers to a parts supplier for the trailer, Meiller-Kipper GmbH of Munich, Germany (founded 1850). The Peenemünde Army Research Center designed the ''Meillerwagen'', and the Gollnow & Son company assembled the ''Meillerwagen'' from supplied components. The ''Meillerwagen'' was assembled with Italy, Italian and Russian Forced labour under German rule during World War II, prisoner laborers of the Government bunker (Germany), Lager Rebstock. The ''Meillerwagen'' was vehicle code number 102 of several vehicles in a V-2 launching battery, which included an 8-ton Sd.Kfz. 7#Germany Army, half-track launch control ...

MW 18014
MW 18014 was a German A-4 test rocket launched on 20 June 1944, at the Peenemünde Army Research Center in Peenemünde. It was the first man-made object to reach outer space, attaining an apogee of , well above the Kármán line that was established later as the lowest altitude of space. It was a vertical test launch, and was not intended to reach orbital velocity, so it returned and impacted Earth, making it the first sub-orbital spaceflight. Background Early A-4 rockets, despite being able to reach altitudes of 90 km, had suffered from multiple reliability problems. For example, a design fault in the forward part of the outer hull caused it to regularly fail mid-flight, resulting in the failure of as many as 70% of test launches. On one occasion, an A-4 rocket suffering from pogo oscillations during ascent veered 90 degrees off course then spiralled back down to its launch pit, killing four launch troops on site. The Peenemünde rocket team made a number of improve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Bombing During World War II
World War II (1939–1945) involved sustained strategic bombing of railways, harbours, cities, workers' and civilian housing, and industrial districts in enemy territory. Strategic bombing as a military strategy is distinct both from close air support of ground forces and from Air supremacy#World War II, tactical air power. During World War II, many military strategists of air power believed that air forces could win major victories by attacking industrial and political infrastructure, rather than purely military targets. Strategic bombing often involved bombing areas inhabited by Non-combatant, civilians, and some campaigns were deliberately designed to target civilian populations in order to terrorism, terrorize them or to weaken their morale. International law at the outset of World War II did not specifically forbid the aerial bombardment of cities – despite the prior occurrence of such bombing during World War I (1914–1918), the Spanish Civil War (1936–1939), and t ...
