German Submarine U-126 (1940)
German submarine ''U-126'' was a Type IXC U-boat of Nazi Germany's ''Kriegsmarine'' during World War II. In six patrols, she sank 25 ships for a total of and 450 tons. She was laid down at the DeSchiMAG AG Weser yard in Bremen as yard number 989 on 1 June 1940, launched on 31 December and commissioned on 22 March 1941 under ''Kapitänleutnant'' Ernst Bauer. The submarine commenced her service with the 2nd U-boat Flotilla, an organization she would stay with, both for training and operations. Design German Type IXC submarines were slightly larger than the original Type IXBs. ''U-126'' had a displacement of when at the surface and while submerged. The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors pr ...

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] |
Siegfried Kietz
Siegfried is a German-language male given name, composed from the Germanic elements ''sig'' "victory" and ''frithu'' "protection, peace". The German name has the Old Norse cognate ''Sigfriðr, Sigfrøðr'', which gives rise to Swedish ''Sigfrid'' (hypocorisms ''Sigge, Siffer''), Danish/Norwegian ''Sigfred''. In Norway, ''Sigfrid'' is given as a feminine name. official statistics at Statistisk Sentralbyrå, National statistics office of Norway, http://www.ssb.no; Statistiska Centralbyrån, National statistics office of Sweden, http://www.scb.se/ The name is medieval and was borne by the legendary dragon-slayer also known as . It did survive in marginal use into the modern period, but after 1876 it enjoyed renewed popularity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharged
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg-Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewerks ...

Draught (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

German Type IXB Submarine
The German Type IXB submarine was a sub-class of the German Type IX submarine built for Nazi Germany's ''Kriegsmarine'' between 1938 and 1940. The U-boats themselves were designed to be fairly large ocean-going submarines. The inspiration for the Type IXB submarine came from the earlier original Type IX submarine, the Type IXA submarine. The design of the IXA was developed to give an increased range, a change which resulted in a slightly heavier overall tonnage. This design was improved even further in the later Type IXC submarines. The class comprised 14 submarines, , , , , , , , , , , , , , and ; thirteen were sunk during the war and the last scuttled by its crew at the end of the war. The Type IXB submarines were the most successful class of submarine in the war in terms of the total amount to tonnage sunk, with each U-boat sinking an average of over during its career. Design and construction Construction All Type IXB submarines were ordered by the Nazi Germany's ''Kriegsma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type IX Submarine
The Type IX U-boat was designed by Nazi Germany's ''Kriegsmarine'' in 1935 and 1936 as a large ocean-going submarine for sustained operations far from the home support facilities. Type IX boats were briefly used for patrols off the eastern United States in an attempt to disrupt the stream of troops and supplies bound for Europe. It was derived from the Type IA, and appeared in various sub-types. Type IXs had six torpedo tubes; four at the bow and two at the stern. They carried six reloads internally and had five external torpedo containers (three at the stern and two at the bow) which stored ten additional torpedoes. The total of 22 torpedoes allowed U-boat commanders to follow a convoy and strike night after night. Some of the IXC boats were fitted for mine operations; as mine-layers they could carry 44 TMA or 66 TMB mines. Secondary armament was provided by one deck gun with 180 rounds. Anti-aircraft armament differed throughout the war. They had two periscopes in the towe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kapitänleutnant
''Kapitänleutnant'', short: KptLt/in lists: KL, ( en, captain lieutenant) is an officer grade of the captains' military hierarchy group () of the German Bundeswehr. The rank is rated OF-2 in NATO, and equivalent to Hauptmann in the Heer and Luftwaffe. It is grade A11 or A12 in the pay rules of the Federal Ministry of Defence. Address In line with ZDv 10/8, the formal manner of addressing people with the rank ''Kapitänleutnant'' (OF-2) is "Herr/Frau Kapitänleutnant". However, in German tradition and in line with seamen's language, the title is abbreviated to "Herr/Frau Kaleu" in verbal communication (contemporary usage). Historically, in the Wehrmacht, the abbreviation spoken was "Herr Kaleun". Rank and assignment The United States Navy's rank of lieutenant is equal to ''Kapitänleutnant'' in NATO's military hierarchy (classed as OF-2). However German Navy ''Kapitänleutnant'' might be assigned to the so-called “line officer career” (de: Truppendienstlaufbahn or Truppe ...

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 ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
