HMS Meteorite
HMS ''Meteorite'' was an experimental U-boat developed in Germany, scuttled at the end of World War II, subsequently raised and commissioned into the Royal Navy. The submarine was originally commissioned into the '' Kriegsmarine'' on 13 March 1945 as ''U-1407''. She was built around a Walter engine fueled by high-test peroxide (HTP). History The three completed German Type XVIIB submarines were scuttled by their crews at the end of the Second World War, at Flensburg and and ''U-1407'' at Cuxhaven, all in the British Zone of Occupation. ''U-1406'' and ''U-1407'' were scuttled on 7 May 1945 by ''Oberleutnant zur See'' Gerhard Grumpelt even though a superior officer, ''Kapitän zur See'' Kurt Thoma, had prohibited such actions. Grumpelt was subsequently sentenced to seven years' imprisonment by a British military court. At the Potsdam Conference in July 1945 ''U-1406'' was allocated to the United States and ''U-1407'' to the United Kingdom, and both were soon salvaged. Roya ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potsdam Conference
The Potsdam Conference (german: Potsdamer Konferenz) was held at Potsdam in the Soviet occupation zone from July 17 to August 2, 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, Prime Ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war. The foreign ministers and aides played key roles: Vyacheslav Molotov, Anthony Eden and Ernest Bevin, and James F. Byrnes. From July 17 to July 25, nine meetings were held, when the Conference was interrupted for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurt Thoma
The Knight's Cross of the Iron Cross (german: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest awards in the military and paramilitary forces of Nazi Germany during World War II. The decoration was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,321 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the acceptance by the Association of Knight's Cross Recipients (AKCR). Presentations were made to members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe (Air Force)—as well as the Waffen-SS, the Reich Labour Service and the Volkssturm (German national militia). There were also 43 foreign recipients of the award. These recipients are listed in the 1986 edition of Walther-Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kapitän Zur See
Captain is the name most often given in English-speaking navies to the rank corresponding to command of the largest ships. The rank is equal to the army rank of colonel and air force rank of group captain. Equivalent ranks worldwide include ship-of-the-line captain (e.g. France, Argentina, Spain), captain of sea and war (e.g. Brazil, Portugal), captain at sea (e.g. Germany, Netherlands) and " captain of the first rank" (Russia). The NATO rank code is OF-5, although the United States of America uses the code O-6 for the equivalent rank (as it does for all OF-5 ranks). Four of the uniformed services of the United States — the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps, and National Oceanic and Atmospheric Administration Commissioned Officer Corps — use the rank. Etiquette Any naval officer who commands a ship is addressed by naval custom as "captain" while aboard in command, regardless of their actual rank, ev ...

Oberleutnant Zur See
''Oberleutnant zur See'' (''OLt zS'' or ''OLZS'' in the German Navy, ''Oblt.z.S.'' in the '' Kriegsmarine'') is traditionally the highest rank of Lieutenant in the German Navy. It is grouped as OF-1 in NATO. The rank was introduced in the Imperial German Navy by renaming the former rank of ''Premier Lieutenant'' in 1890. Within the navy officers of this rank were simply addressed as ''Herr Oberleutnant''. To distinguish naval officers from those of the army, the suffix ''zur See'' (at sea) was added in official communications, sometimes shortened to ''z.S.'' (''Oblt.z.S.''). The rank has since been used by the ''Reichsmarine The ''Reichsmarine'' ( en, Realm Navy) was the name of the German Navy during the Weimar Republic and first two years of Nazi Germany. It was the naval branch of the '' Reichswehr'', existing from 1919 to 1935. In 1935, it became known as the ...'', '' Kriegsmarine'', and '' Bundesmarine''.

Allied Occupation Zones In Germany
Germany was already de facto occupied by the Allies from the real fall of Nazi Germany in World War II on 8 May 1945 to the establishment of the East Germany on 7 October 1949. The Allies (United States, United Kingdom, Soviet Union, and France) asserted joint authority and sovereignty at the 1945 Berlin Declaration. At first, defining Allied-occupied Germany as all territories of the former German Reich before Nazi annexing Austria; however later in the 1945 Potsdam Conference of Allies, the Potsdam Agreement decided the new German border as it stands today. Said border gave Poland and the Soviet Union all regions of Germany (eastern parts of Pomerania, Neumark, Posen-West Prussia, Free City of Danzig, East-Prussia & Silesia) east of the Oder–Neisse line and divided the remaining "Germany as a whole" into the four occupation zones for administrative purposes under the three Western Allies (the United States, the United Kingdom, and France) and the Soviet Union.

German Type XVIIB Submarine
The Type XVII U-boats were small coastal submarines that used a high-test peroxide propulsion system, which offered a combination of air-independent propulsion and high submerged speeds. Background In the early 1930s Hellmuth Walter had designed a small, high-speed submarine with a streamlined form propelled by high-test peroxide (HTP) and in 1939 he was awarded a contract to build an experimental vessel, the 80 ton , which achieved an underwater speed of during trials in 1940. In November 1940 Admirals Erich Raeder and Werner Fuchs (head of the ''Kriegsmarine''s Construction Office) witnessed a demonstration of the ''V-80''; Raeder was impressed, but Fuchs was slow to approve further tests. Following the success of the ''V-80's'' trials, Walter contacted Karl Dönitz in January 1942, who enthusiastically embraced the idea and requested that these submarines be developed as quickly as possible. An initial order was placed in summer 1942 for four Type XVIIA development submarines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-test Peroxide
High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water. It was used as a propellant of HTP rockets and torpedoes, and has been used for high-performance vernier engines. Properties Hydrogen peroxide works best as a propellant in extremely high concentrations (roughly over 70%). Although any concentration of peroxide will generate some hot gas (oxygen plus some steam), at concentrations above approximately 67%, the heat of decomposing hydrogen peroxide becomes large enough to completely vaporize all the liquid at standard pressure. This represents a safety and utilization turning point, since decomposition of any concentration above this amount is capable of transforming the liquid entirely to heated gas (the higher the concentration, the hotter the resulting gas).

Hellmuth Walter
Hellmuth Walter (26 August 1900 – 16 December 1980) was a German engineer who pioneered research into rocket engines and gas turbines. His most noteworthy contributions were rocket motors for the Messerschmitt Me 163 and Bachem Ba 349 interceptor aircraft, so-called ''Starthilfe'' jettisonable rocket propulsion units used for a variety of Luftwaffe aircraft during World War II, and a revolutionary new propulsion system for submarines known as air-independent propulsion (AIP). Early life Walter began training as a machinist in 1917 in Hamburg and in 1921 commenced studies in mechanical engineering at the Technical University of Berlin. He left before completing these studies, however, in order to take up a position at the Stettiner Maschinenbau AG Vulcan, a major shipyard. Walter's experience with marine engines here led him to become interested in overcoming some of the limitations of the internal combustion engine. He reasoned that an engine powered by a fuel source alr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
