Ingenieurbüro Glückauf
The Ingenieurbüro Glückauf was a department of the Reich Ministry of Armaments and War Production, which during the Second World War was the design office of the Hauptausschuß Schiffbau. It completed construction and production plans for U-Boats of the Kriegsmarine. This affected both submarine types that were designed for the U-boat war, as well as midget submarines which were used by the small combat units of the Kriegsmarine. Tasks, projects and localization The Ingenieurbüro Glückauf was abbreviated as IBG. It was entrusted with the design and production planning of German submarines for the Navy during the final phases of World War II, for example the Type XXI submarine or the Type XXVII submarine. Towards the end of 1944, the design and production planning for the Type XXVI, which used the {{ill, Walter engine, de, Walter-Antrieb, was completed. For this purpose, the IBG designers produced construction drawings in the partial sheet system, from which the sequence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reich Ministry 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 The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force).

Second World War
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] |
U-Boats
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines (U-boat ...

Battle Of The Atlantic
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German '' Kriegsmarine'' (Navy) and aircraft of the ''Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning September 13, 1941. Carney, Robert B., Admiral, USN. "Comment and Discu ...

Midget Submarine
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same John Philip Holland, designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-class submarine, X-craft and the unsuccessful Welman subm ...

Organization Of The Kriegsmarine
The organization of the ''Kriegsmarine'' refers to the operational and administrative structure of the German Navy from 1935 to 1945. Many of the organizational tenets of the Kriegsmarine were inherited from its predecessor the Reichsmarine. As World War II unfolded, the Kriegsmarine expanded to cover additional regions and responsibilities, most significant of which was the occupation of France and the Battle of the Atlantic. Navy High Command The ultimate command authority for the Kriegsmarine was the ''Oberkommando der Marine'' (OKM), which was headed by the Commander-in-Chief of the Germany Navy (''Oberbefehlshaber der Kriegsmarine''). OKM in turn answered to the '' Oberkommando der Wehrmacht''; naval affairs were often run independently from the wishes of the Army, under the authority of the ''Oberkommando des Heeres''. The Navy and the Luftwaffe (Air Force) further had little coordination, leading to serious delays in the development of naval aviation. The following ...

Institut Für Zeitgeschichte
The Institute of Contemporary History (''Institut für Zeitgeschichte'') in Munich was conceived in 1947 under the name ''Deutsches Institut für Geschichte der nationalsozialistischen Zeit'' ("German Institute of the History of the National Socialist Era"). Founded by the German government and the State of Bavaria at the suggestion of the Allied Forces, it was established in 1949 and renamed in 1952. Its purpose is the analysis of contemporary German history. History The institute is funded by the German government, and the German states of Bavaria, Baden-Württemberg, Brandenburg, Hesse, Lower Saxony, North Rhine-Westphalia and Saxony. The first director of the institute was Hans Rothfels, the second director was Martin Broszat. Representatives of the supporting states are also members of the institute's board. Since 1953, the institute has been publishing the journal ' (''Contemporary History Quarterly''), which is regarded as one of the most important publications of German hi ...

Type XXI Submarine
Type XXI submarines were a class of German diesel–electric ''Elektroboot'' (German: "electric boat") submarines designed during the Second World War. One hundred and eighteen were completed, with four being combat-ready. During the war only two were put into active service and went on patrols, but these were not used in combat. They were the first submarines designed to operate primarily submerged, rather than spending most of their time as surface ships that could submerge for brief periods as a means of escaping detection. They incorporated many batteries to increase the time they could spend submerged, to as much as several days, and they only needed to surface to periscope depth for recharging via a snorkel. The design included many general improvements as well: much greater underwater speed by an improved hull design, greatly improved diving times, power-assisted torpedo reloading and greatly improved crew accommodations. However, the design was also flawed in many ways, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seehund
''Seehund'' (German: "seal"), also known as Type XXVII, was a midget submarine built by Nazi Germany during World War II. Designed in 1944 and operated by two-man crews, it was used by the ''Kriegsmarine'' (German Navy) during the closing months of the war, sinking nine merchant vessels and damaging an additional three, while losing 35 boats, mostly attributed to bad weather. The French Navy used four captured boats after the war until 1953. History The origin of the ''Seehund'' began with the salvage of the two British X class submarines and which had been lost by the Royal Navy during Operation Source, an attempt to sink the German battleship ''Tirpitz''. ''Hauptamt Kriegschiffbau'' subsequently produced a design for a two-man submarine based on inspection of the British boats, designated Type XXVIIA and named ''Hecht'' ("Pike"). XXVIIA (Hecht) Like the British X class boats, the Type XXVIIA was designed to carry explosive charges to be laid beneath enemy ships, but it wa ...

Type XXVI Submarine
The Type XXVI was a German submarine project towards the end of the Second World War. Only five boats went into production, none of which were completed. Concept After the use of electric propulsion in submarine construction in the course of the development of the Type XXI and XXIII submarines, the designs of Types XVII, XVIII and XXII by Walterwerke were not pursued any further. When it turned out that the XXI boats were unsuitable for the tactical requirements of the convoy raids, the Kiel family company saw the opportunity for a "Walter U-boat" again and on October 12, 1943 presented a concept with the designation XXVIA . On March 28 of the following year, the Commander-in-Chief of the Navy, Karl Dönitz, decided to have the boat built under the type designation XXVIW (for Walter). A week later, the naval war command formulated the requirements that the new type of boat had to meet, which was now given the designation XXVI. Then the Ingenieurbüro Glückauf (IBG) was ent ...

Harz
The Harz () is a highland area in northern Germany. It has the highest elevations for that region, and its rugged terrain extends across parts of Lower Saxony, Saxony-Anhalt, and Thuringia. The name ''Harz'' derives from the Middle High German word ''Hardt'' or ''Hart'' (hill forest). The name ''Hercynia'' derives from a Celtic name and could refer to other mountain forests, but has also been applied to the geology of the Harz. The Brocken is the highest summit in the Harz with an elevation of above sea level. The Wurmberg () is the highest peak located entirely within the state of Lower Saxony. Geography Location and extent The Harz has a length of , stretching from the town of Seesen in the northwest to Eisleben in the east, and a width of . It occupies an area of , and is divided into the Upper Harz (''Oberharz'') in the northwest, which is up to 800 m high, apart from the 1,100 m high Brocken massif, and the Lower Harz (''Unterharz'') in the east which is up to aroun ...
