German Submarine U-537
German submarine ''U-537'' was a Type IXC/40 U-boat of Nazi Germany's ''Kriegsmarine'' during World War II. Her keel was Keel laying, laid down on 10 April 1942 by Deutsche Werft in Hamburg. She was ship commissioning, commissioned on 27 January 1943 with ''Kapitänleutnant'' Peter Schrewe in command. Schrewe commanded the boat for nearly two years, until her loss. ''U-537'' conducted three patrols and holds the distinction of making the only armed German landing in North America during World War II, when her crew installed the automatic Weather Station Kurt in Attacks on North America during World War II#Martin Bay, Martin Bay, Labrador on 22 October 1943. She was then sent to the Far East. On 10 November 1944 in the Java Sea east of Surabaya, ''U-537'' was sunk with all hands—58 officers and men—by torpedoes from .

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] |
Type IX U-boat
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] |
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 ...

Java Sea
The Java Sea ( id, Laut Jawa, jv, Segara Jawa) is an extensive shallow sea on the Sunda Shelf, between the Indonesian islands of Borneo to the north, Java to the south, Sumatra to the west, and Sulawesi to the east. Karimata Strait to its northwest links it to the South China Sea. It is a part of the western Pacific Ocean. Geography The Java Sea covers the southern section of the Sunda Shelf. A shallow sea, it has a mean depth of . It measures about east-west by north-southGoogleEarth and occupies a total surface area of . It formed as sea levels rose at the end of the last ice age. Its almost uniformly flat bottom, and the presence of drainage channels (traceable to the mouths of island rivers), indicate that the Sunda Shelf was once a stable, dry, low-relief land area (peneplain) above which were left standing a few monadnocks (granite hills that, due to their resistance to erosion, form the present islands). Extent The International Hydrographic Organization (IHO) defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attacks On North America During World War II
The American Theater was a theater of operations during World War II including all continental American territory, and extending into the ocean. Owing to North and South America's geographical separation from the central theaters of conflict (in Europe, the Mediterranean and Middle East, and the Pacific) the threat of an invasion of the continental U.S. or other areas in the Americas by the Axis Powers was negligible and the theater saw relatively little conflict. However, despite the relative unimportance of the American Theater, some battles took place within it, including the Battle of the River Plate, submarine attacks off the East Coast, the Aleutian Islands campaign, the Battle of the St. Lawrence, and the attacks on Newfoundland. Espionage efforts included Operation Bolívar.

Weather Station Kurt
Weather Station Kurt (Wetter-Funkgerät Land-26) was an automatic weather station, erected by a German U-boat crew in northern Labrador, Dominion of Newfoundland, in October 1943. Installing the equipment for the station was the only known armed German military operation on land in North America during the Second World War. After the war it was forgotten until its rediscovery in 1977. Background In the northern hemisphere, weather systems in temperate climates predominantly move from west to east. This gave the Allies an important advantage. The Allied network of weather stations in North America, Greenland, and Iceland allowed the Allies to make more accurate weather forecasts than the Germans. German meteorologists used weather reports sent by U-boats and weather ships, such as ''Lauenburg'', operating in the North Atlantic. They also had reports from clandestine weather stations in remote parts of the Arctic and readings collected over the Atlantic by specially equipped we ...

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] |
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] |
