Delphin (molecule)
''Delphin'' (dolphin) was a midget submarine created during World War II. Designed in 1944, only three prototypes were created by Nazi Germany's Kriegsmarine by the end of the war, all of which were destroyed. The ''Delphin'' was built for underwater speed attacks, as German engineers under the leadership of Ulrich Gabler discovered that past midget submarines were too slow to match the speeds of large ships in the English Channel. ''Delphin'' weighed and was easily recognizable due to its tear-drop shape, which allowed the vessel to travel through the water at higher speeds. During trials, the submarine reached a speed of seventeen knots while submerged. On 19 January 1945, the first prototype was destroyed after a collision with a boat and resulted in further testing being abandoned. Two other prototypes under construction in Berlin were moved to Pötenitz near Trave, where they were blown up as Allied An alliance is a relationship among people, groups, or state ...

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 ...

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] |
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] |
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 ...

Ulrich Gabler
Ulrich Gabler (1 October 1913 – 24 February 1994) was a German shipbuilding engineer, who specialized in the design and development of diesel-powered submarines. During World War II he served as chief engineer in the U-boat force on and , then under the command of Reinhard Suhren. Suhren had recommended Gabler for the Knight's Cross of the Iron Cross, a request that was turned down and Gabler received the German Cross in Gold on 15 October 1942. Following his war patrols on ''U-564'' he worked on the design and development of the U-boat classes XXII, XVII A and XXVI. After the war he founded the ''Ingenieurkontor Lübeck'' (IKL) which among others designed the type 201, 202 and 209 submarines. In 1963 he was appointed honorary professor at the University of Hamburg for shipbuilding.

Tear-drop Hull
A teardrop hull is a submarine hull design which emphasizes submerged performance over surfaced performance. It was somewhat commonly used in the early stages of submarine development, but was gradually abandoned in the early 20th century in favour of designs optimized for high performance on the surface as a result of changes in operational doctrine. Although naval doctrine changed, design practices remained until the later parts of World War II when the German Kriegsmarine suffered ever-growing losses of submarines in the Battle of the Atlantic. In an attempt to combat the growing threat of allied anti-submarine efforts, experimental design concepts dating back to the late interbellum were shoehorned into the existing submarine design process, resulting in a small number of hydrogen peroxide-powered submarines as well as the Elektroboot family of diesel-electric submarine classes. Although too late and too few to turn the war around, examination of these boats in the immediat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Trave
The Trave () is a river in Schleswig-Holstein, Germany. It is approximately long, running from its source near the village of Gießelrade in Ostholstein to Travemünde, where it flows into the Baltic Sea. It passes through Bad Segeberg, Bad Oldesloe, and Lübeck, where it is linked to the Elbe–Lübeck Canal. It is navigable for sea-going vessels from the Baltic to the Lübeck ports. The Herren Tunnel crosses the Trave, as do numerous bridges, and a ferry connects Travemünde with Priwall Peninsula, Priwall. Tributaries of the Trave include the Wakenitz and the Stepenitz (Trave), Stepenitz.

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...
