U-176
German submarine ''U-176'' was a Type IXC U-boat in Nazi Germany's ''Kriegsmarine'' during World War II. Built at the DeSchiMAG AG Weser shipyard in Bremen, she was laid down on 6 February 1941, launched on 12 September and commissioned on 15 December, under the command of ''Kapitänleutnant'' Reiner Dierksen. ''U-176'' served with the ''4. Unterseebootsflotille'' (U-boat flotilla) while training, and from 1 August 1942 with the ''10th U-boat Flotilla'', a long-range operations unit. ''U-176'' completed three patrols, sinking 11 ships totalling before she was sunk off Cayo Blanquizal by the Cuban Navy on 15 May 1943. Design German Type IXC submarines were slightly larger than the original Type IXBs. ''U-176'' 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 di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reiner Dierksen
Reiner Dierksen (24 March 1908 – 15 May 1943) was a German U-boat commander in World War II and posthumous recipient of the German Cross in Gold. Naval career Reiner Dierksen joined the ''Reichsmarine'' in 1933. From October 1938 to June 1940 he was Commander M 5 of the 1st Mineseweeping flotilla, then he was the Commander of the 32nd Minesweeping flotilla until March 1941. Dierksen began his U-boat training in March 1941, then took his U-boat Commander training and U-boat familiarization until 15 December 1941 when he commissioned the Type IXC at Bremen. On his second patrol with U-176 Dierksen ran into one of the most stubborn victims of the entire war when he spent almost 48 hours hunting the Dutch steam merchant, Polydorus, before finally sinking her with his 7th and 8th torpedoes. Korvettenkapitän Reiner Dierksen died when his U-176 was sunk with all hands, 53 men, on its 3 war patrol north of Cuba on 15 May 1943 by Cuban patrol boat ''CS 13''. Dierksen had sunk 10 ship ...

Cuban Navy
The Cuban Revolutionary Navy ( es, Marina de Guerra Revolucionaria) is the navy of Cuba. History The Constitutional Navy of Cuba was the navy of Cuba that existed prior to 1959. During World War II, it sank the German submarine ''U-176'' on 15 May 1943. During the Cold War, the Cuban Navy successfully captured the freighters Leyla Express and Johnny Express, both vessels blamed for CIA-related activities against Cuba. In 1988, the Cuban Navy boasted 12,000 men, three submarines, two modern guided-missile frigates, one intelligence vessel, and a large number of patrol craft and minesweepers. However, most of the Soviet-made vessels have been decommissioned or sunk to make reefs. By 2007, the Cuban Navy was assessed as being 3,000 strong (including up to 550+ Navy Infantry) by the IISS with six Osa-II and one . The Cuban Navy also includes a small marine battalion called the ''Desembarco de Granma''. It once numbered 550 men though its present size is not known. Cuban N ...

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] |
U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...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] |

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] |
