German Destroyer Z17 Diether Von Roeder
''Z17 Diether von Roeder'' was one of six Type 1936 destroyers built for the ''Kriegsmarine'' (German Navy) in the late 1930s. Completed in 1938, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939. At the beginning of World War II in September, the ship was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, the ship helped lay an offensive minefield off the English coast that claimed seven merchant ships. During the German invasion of Norway in April 1940, ''Z17 Diether von Roeder'' was tasked to attack Narvik and participated in both the First and Second Naval Battles of Narvik. She was crippled by British destroyers during the first battle, but was able to severely damage a British destroyer during the second battle, before she had to be scuttled to prevent her capture.

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines (U-boat ...

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 ...

Length At The Waterline
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Scuttled
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel in t ...

Second Naval Battle Of Narvik
The Battles of Narvik were fought from 9 April to 8 June 1940, as a naval battle in the Ofotfjord and as a land battle in the mountains surrounding the north Norwegian town of Narvik, as part of the Norwegian Campaign of the Second World War. The two naval battles in the Ofotfjord on 10 April and 13 April were fought between the British Royal Navy and Nazi Germany ''Kriegsmarine'', while the two-month land campaign was fought between Norwegian, French, British, and Polish troops against German mountain troops, shipwrecked Kriegsmarine sailors and German paratroopers (''Fallschirmjäger'') from the 7th Air Division. Although defeated at sea off Narvik, losing control of the town of Narvik and being pushed back towards the Swedish border, the Germans eventually prevailed because of the Allied evacuation from Norway in June 1940 following the Battle of France. Narvik provided an ice-free harbour in the North Atlantic for iron ore transported by rail from Kiruna in Sweden. Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Weserübung
Operation Weserübung (german: Unternehmen Weserübung , , 9 April – 10 June 1940) was Germany's assault on Denmark and Norway during the Second World War and the opening operation of the Norwegian Campaign. In the early morning of 9 April 1940 (''Wesertag'', "Weser Day"), Germany occupied Denmark and invaded Norway, ostensibly as a preventive manoeuvre against a planned, and openly discussed, French-British occupation of Norway known as Plan R 4 (actually developed as a response to any German aggression against Norway). After the occupation of Denmark (the Danish military was ordered to stand down as Denmark did not declare war with Germany), envoys of the Germans informed the governments of Denmark and Norway that the ''Wehrmacht'' had come to protect the countries' neutrality against Franco-British aggression. Significant differences in geography, location and climate between the two nations made the actual military operations very dissimilar. The invasion fleet's no ...

Minefield
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skagerrak
The Skagerrak (, , ) is a strait running between the Jutland peninsula of Denmark, the southeast coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea area through the Danish Straits to the Baltic Sea. The Skagerrak contains some of the busiest shipping routes in the world, with vessels from every corner of the globe. It also supports an intensive fishing industry. The ecosystem is strained and negatively affected by direct human activities. Oslo and Gothenburg are the only large cities in the Skagerrak region. Name The meaning of ''Skagerrak'' is most likely the Skagen Channel/Strait. Skagen is a town near the northern cape of Denmark (The Skaw). ''Rak'' means 'straight waterway' (compare the Damrak in Amsterdam); it is cognate with '' reach''.Nudansk Ordbog (1993), 15th edition, 2nd reprint, Copenhagen: Politikens Forlag, entry ''Skagerrak''. The ultimate source of this syllable is the Proto-Indo-European root *reg-, 'straight'. ''Rak'' me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
