U-1230
German submarine ''U-1230'' was a Type IXC/40 U-boat of Nazi Germany's ''Kriegsmarine'' during World War II. Laid down on 15 March 1943 at the Deutsche Werft in Hamburg, and commissioned on 26 January 1944 under the command of '' Kapitänleutnant'' Hans Hilbig, it only undertook one patrol, operating from Horten Naval Base, Norway, returning safely to Kristiansand, Norway in early 1945. Design German Type IXC/40 submarines were slightly larger than the original Type IXCs. ''U-1230'' had a displacement of when at the surface and while submerged.

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.

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] |

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] |
Karljohansvern
Karjohansvern (''Karljohansvern Orlogsstasjon, KJV'') at Horten was the main base for the Royal Norwegian Navy from 1850 to 1963. Background In 1818, it was decided to establish a naval base in Horten. It was first called ''Hortens verft'', and later ''Marinens Hovedværft'' until King Oscar I named it ''Carljohansværn værft'' in 1854 (after his father Karl Johan). The shipyards was begun in 1820 and the first launch, a frigate, was in 1828. On 9 April 1940 during the German invasion of Norway, a battle took place in the harbour when the Germans attempted to seize the base. The naval attack was repulsed, but German troops managed to outflank the Norwegians and force them to capitulate. Karljohansvern remained in German hands for the rest of World War II, while the ships operating out of it were pressed into their service. In 1953, the Norwegian Parliament determined the Navy's main base should be moved to Bergen. When the new headquarters at Haakonsvern was officially op ...

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] |
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] |
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 ...

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 ...

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] |
