German Submarine U-2365
German submarine ''Hai'', the former ''U-2365'' Type XXIII U-boat of Nazi Germany's ''Kriegsmarine'' during World War II, was one of the first submarines of the ''Bundesmarine''. She was ordered on 20 September 1944, and was laid down on 6 December 1944 at Deutsche Werft AG, Hamburg, as yard number 519. She was launched on 26 January 1945 and commissioned under the command of ''Oberleutnant zur See'' Fritz-Otto Korfmann on 2 March 1945. Scuttled on 8 May 1945, the boat was raised in June 1956 and commissioned into the newly founded ''Bundesmarine'' as ''Hai'', where she served until she sank by accident on 14 September 1966. Design Like all Type XXIII U-boats, ''U-2365'' had a displacement of when at the surface and while submerged. She had a total length of ( o/a), a beam width of (o/a), and a draught depth of . The submarine was powered by one MWM six-cylinder RS134S diesel engine providing , one AEG GU4463-8 double-acting electric motor electric motor providing , and o ...

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 It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic.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 ...

German Federal Navy
The German Navy (, ) is the navy of Germany and part of the unified ''Bundeswehr'' (Federal Defense), the German Armed Forces. The German Navy was originally known as the ''Bundesmarine'' (Federal Navy) from 1956 to 1995, when ''Deutsche Marine'' (German Navy) became the official name with respect to the 1990 incorporation of the East German ''Volksmarine'' (People's Navy). It is deeply integrated into the NATO alliance. Its primary mission is protection of Germany's territorial waters and maritime infrastructure as well as sea lines of communication. Apart from this, the German Navy participates in peacekeeping operations, and renders humanitarian assistance and disaster relief. It also participates in anti-piracy operations. History The German Navy traces its roots back to the ''Reichsflotte'' (Imperial Fleet) of the revolutionary era of 1848–52. The ''Reichsflotte'' was the first German navy to sail under the black-red-gold flag. Founded on 14 June 1848 by the orders o ...

Operation Regenbogen (U-boat)
Operation Regenbogen (, "Rainbow Order") was the code name for the planned mass scuttling of the German U-boat fleet, to avoid surrender, at the end of World War II. Background At the beginning of May 1945 Nazi Germany was collapsing under the Allied onslaught. The Soviets had captured Berlin, and on 30 April Hitler had committed suicide Suicide is the act of intentionally causing one's own death. Mental disorders (including major depressive disorder, depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders), physical disorders (such as chronic f ....

Kattegat
The Kattegat (; sv, Kattegatt ) is a sea area bounded by the Jutlandic peninsula in the west, the Danish Straits islands of Denmark and the Baltic Sea to the south and the provinces of Bohuslän, Västergötland, Halland and Skåne in Sweden in the east. The Baltic Sea drains into the Kattegat through the Danish Straits. The sea area is a continuation of the Skagerrak and may be seen as a bay of the North Sea, but in traditional Scandinavian usage, this is not the case. The Kattegat is a rather shallow sea and can be very difficult and dangerous to navigate because of the many sandy and stony reefs and tricky currents, which often shift. In modern times, artificial seabed channels have been dug, many reefs have been dredged by either sand pumping or stone fishing, and a well-developed light signaling network has been installed, to safeguard the very heavy international traffic of this small sea. There are several large cities and major ports in the Kattegat, including, in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self destruct, self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a Channel (geography), channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a Cog (ship), cog preserved from the keel up to the decks in the silt was discovered alongside ...

Silent Running (submarine)
Silent running is a stealth mode of operation for naval submarines. The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise. The protocol has been in use since the latter part of World War I, when hydrophones were invented to detect U-boats. The propellers have a characteristic RPM band in which no cavitation noise arises. Since this rotation speed is usually relatively low, the first electric submarines had special "silent running" engines designed for optimum performance at reduced speed. These required less active cooling (further reducing noise), and were generally equipped with plain bearings rather than ball bearings. These engines were also acoustically decoupled from the hull, as they employed belt transmission rather than direct coupling to the propeller shaft. Nuclear submarines can ...

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'', ''Kriegsmarine'', and ''Bundesmarine''. In the ''Volksmarine'' the rank was originally used in the same way until the suffix ''zur See'' was dropped. In the ''Kriegsmarine'' engineers (''Ingenieur – Ing.'') of the same rank were distinguished as ''Oberleutnant (Ing.)''.

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...
