German Submarine U-548
German submarine ''U-548'' was a Type IXC U-boat of Nazi Germany's ''Kriegsmarine'' during World War II. She was laid down at the ''Deutsche Werft'' (yard) in Hamburg as yard number 369 on 4 September 1942, launched on 14 April 1943 and commissioned on 30 June with ''Kapitänleutnant'' Eberhard Zimmermann in command. ''U-548'' began her service career with training as part of the 4th U-boat Flotilla from 30 June 1943. She was reassigned to the 2nd flotilla for operations on 1 April 1944, then the 33rd flotilla on 1 October. She carried out four patrols and sank one ship. She was sunk on 19 April 1945 by depth charges from American warships southeast of Halifax, Nova Scotia. Design German Type IXC/40 submarines were slightly larger than the original Type IXCs. ''U-548'' 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 ... [...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] |
33rd U-boat Flotilla
''33rd U-boat Flotilla'' ("33. Unterseebootsflottille") was a front-line unit of Nazi Germany's '' Kriegsmarine'' during World War II. The flotilla was founded at Flensburg in September 1944 under the command of ''Korvettenkapitän'' Georg Schewe, though ''Korvkpt.'' Günter Kuhnke took over the command in October 1944. The flotilla included U-boats that had been based at the French submarine bases captured by the Allied advance during the Normandy Campaign, as well as U-boats operating in the Indian Ocean (the ''Monsun Gruppe''). The flotilla was disbanded in May 1945 after the German surrender. Flotilla commanders * ''Korvettenkapitän'' Georg Schewe (September–October 1944) * ''Korvettenkapitän'' Günter Kuhnke Günter Kuhnke (7 September 1912 – 11 October 1990) was a German submarine commander during World War II and later a Konteradmiral with the Bundesmarine, West Germany's navy.

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 ...

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] |
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] |
