V-2 Rocket Facilities Of World War II
V-2 rocket facilities were military installations associated with Nazi Germany's V-2 SRBM ballistic missile, including bunkers and small launch pads which were never operationally used. Development, testing, and production facilities V-2 research was conducted at the Peenemünde Army Research Center with most Peenemünde test launches conducted from Test Stand VII. After having moved the launch training facility named "Heimat-Artillerie-Park 11 Karlshagen/Pomerania" from Köslin near Peenemünde, the Training and Testing Battery 444 (german: Lehr- und Versuchsbatterie Nr 444) conducted "live warhead trials" from the Heidelager military area near Blizna, Poland, into the target area at the Pinsk Marshes, Pripet Marshes to the northeast. With the advances by the Russian armies, the Blizna testing was evacuated on September 8, 1944 to the Tuchola Forest#History, Heidekraut testing-ground in the Tuchola Forest in Polish Pomerania. In mid-January 1945, testing moved to the forests ...

Supersonic Wind Tunnel
A supersonic wind tunnel is a wind tunnel that produces supersonic speeds (1.2< M<5) The Mach number and flow are determined by the nozzle geometry. The Reynolds number is varied by changing the density level (pressure in the settling chamber). Therefore, a high pressure ratio is required (for a supersonic regime at M=4, this ratio is of the order of 10). Apart from that, condensation of moisture or even gas liquefaction can occur if the static temperature becomes cold enough. This means that a supersonic wind tunnel usually needs a drying or a pre-heating facility. A supersonic wind tunnel has a large power demand, so most are designed for intermittent instead of continuous operation.


Restrictions for supersonic tunn ...

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 began the Crossbow campaign against the German V-weapon programme. The British lost 215 aircrew and 40 bombers, and killed several hundred enslaved workers in the nearby Trassenheide forced labour camp. The ''Luftwaffe'' lost twelve night-fighters and about 170 German civilians were killed, including two V-2 rocket scientists. Prototype V-2 rocket launches were delayed for about two months, testing and production was dispersed and the morale of the German survivors was severely affected. However, the impact of the operation on German war production was deemed insufficient. Background German rocket research To evade the restrictions of the ...

Ilfeld
Ilfeld is a village and a former municipality in the district of Nordhausen, in Thuringia, Germany.

Mittelbau-Dora
Mittelbau-Dora (also Dora-Mittelbau and Nordhausen-Dora) was a Nazi concentration camp located near Nordhausen in Thuringia, Germany. It was established in late summer 1943 as a subcamp of Buchenwald concentration camp, supplying slave labour from many Eastern countries occupied by Germany (including evacuated survivors of eastern extermination camps), for extending the nearby tunnels in the Kohnstein and for manufacturing the V-2 rocket and the V-1 flying bomb. In the summer of 1944, ''Mittelbau'' became an independent concentration camp with numerous subcamps of its own. In 1945, most of the surviving inmates were sent on death marches or crammed in trains of box-cars by the SS. On 11 April 1945, US troops freed the remaining prisoners. The inmates at Dora-Mittelbau were treated in a brutal and inhumane manner, working 14-hour days and being denied access to basic hygiene, beds, and adequate rations. Around one in three of the roughly 60,000 prisoners who were sent to Dora ...

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.

Forced Labor
Forced labour, or unfree labour, is any work relation, especially in modern or early modern history, in which people are employed against their will with the threat of destitution, detention, violence including death, or other forms of extreme hardship to either themselves or members of their families. Unfree labour includes all forms of slavery, penal labour and the corresponding institutions, such as debt slavery, serfdom, corvée and labour camps. Definition Many forms of unfree labour are also covered by the term forced labour, which is defined by the International Labour Organization (ILO) as all involuntary work or service exacted under the menace of a penalty. However, under the ILO Forced Labour Convention of 1930, the term forced or compulsory labour does not include: *"any work or service exacted in virtue of compulsory military service laws for work of a purely military character;" *"any work or service which forms part of the normal civic obligations of ...

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.

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 ...

Raxwerke
Raxwerke or Rax-Werke was a facility of the Wiener Neustädter Lokomotivfabrik at Wiener Neustadt in Lower Austria. During World War II, the company also produced lamps for Panzer tanks and anti-aircraft guns. Two Raxwerke plants employed several thousand forced laborers from the Mauthausen-Gusen concentration camp (on 20 June 1943 Mauthausen delivered ~500 prisoners to the Rax-Werke). Operations Part of the Eastern Works (V-2 facilities in the Vienna-Freidrichshafen area), the 30 meter-high Serbs hall at the Raxwerke was selected for V-2 manufacturing. A few V-2 center sections had been assembled by the Raxwerke when, on 2 November 1943, the US Fifteenth Air Force targeted the nearby Wiener Neustädter Flugzeugwerke (WNF) plant in Operation Crossbow and hit the Raxwerke. Rax test equipment was subsequently moved to the site of the Redl-Zipf brewery in central Austria (code name Schlier) where V-2 test stands were built. Werner Dahm was sent from Peenemünde Army Research Cent ...
