R Boats
The R boats (''Räumboote'' in German, meaning ''minesweeper'') were a group of small naval vessels built as minesweepers for the '' Kriegsmarine'' (German navy) before and during the Second World War. They were used for several purposes during the war, and were also used post-war by the German Mine Sweeping Administration for clearing naval mines. In 1954, the Indonesian Navy ordered 10 ''Pulau Rau''-class minesweepers to Abeking & Rasmussen in West Germany. The ''Pulau Rau''-class were modified R boats armed with one Bofors 40mm L/60 Mk 3 gun, two Oerlikon 20mm/70 Mk 10 guns and also mechanical minesweeping gear. Operational use A total of 424 boats were built for the '' Kriegsmarine'' before and during World War II. The German Navy used them in every theatre including the Baltic, Mediterranean, the Arctic and the Black Sea. In addition to its designed use as minesweepers, these boats were used for convoy escort, coastal patrol, minelaying and air-sea rescue. About 140 R b ...

Bremen-Vegesack
Vegesack is a northern district of the city of Bremen. Geography ''Vegesack'' is located about north from the centre of Bremen-city at the mouth of the river Lesum, beside the river Weser (). Abutting the district of Vegesack to the northwest is the district of Blumenthal, in the southeast the district of Burglesum. Across the river Weser is the Lower Saxony village Lemwerder, connected to Vegesack by a ferry service. History Vegesack was established long before the 14th century. At that time the mouth of the river Lesum and the small brook Aue to the river Weser was a preferred and protected berth for sailing ships in the winter time or in the stormy seasons. Therefore, the first buildings might have been a few workshops and accommodations and pubs for the sailors. After the first mention of a ferry across the Weser in the 14th century, the name "Vegesack" was first used in 1453. The source and the meaning of the name is unknown but might be derived from the pub "Thom Fege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Minesweepers Of Germany
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweepers Of The Kriegsmarine
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Boat Types
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size, shape, cargo or passenger capacity, or its ability to carry boats. Small boats are typically found on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats, such as the whaleboat, were intended for use in an offshore environment. In modern naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence. Lighters are used to conve ...

Sperrbrecher
A ''Sperrbrecher'' (German; informally translated as "pathfinder" but literally meaning "mine barrage breaker"), was a German auxiliary ship of the First World War and the Second World War that served as a type of minesweeper, steaming ahead of other vessels through minefields and detonating them with their reinforced hull. Also used as anti-aircraft ships, the ''Sperrbrecher'' suffered heavy losses in the war. Operational history ''Sperrbrecher'' were used extensively by the Germans in World War I. The Imperial Fleet had a total of thirty ''Sperrbrecher'' for clearing mine streets – eight were lost during the war. Some of these ships were equipped with airplanes, such as ''Rio Negro'', ''Plauen'' or ''Wigbert''. In World War II officially designated as 'Special Purpose Merchant Ships', although termed by the Royal Air Force as "Heavy Flak Ship",Paterson 2004, p. 165. the ''Sperrbrecher'' were converted from merchant ships for their special role, were primarily crewed by merchan ...

M-class Minesweeper (Germany)
The M class were the standard minesweeper (german: Minensuchboot) of Nazi Germany's ''Kriegsmarine'' during World War II. The vessels were the primary force in Germany's harbor defense command and were organized administratively into minesweeper flotillas. History M1915 and M1916 A total of 36 old units from World War I served in World War II. Some of these were converted to experimental ships, artillery school ships, fleet tenders or R-boat tenders, and 1 (ex-M109) was converted into a survey ship. In 1940, most of these converted vessels were re-designated as minesweepers again. M1935 The first series; the M1935 were ordered in the late 1930s to replace worn out World War I vintage boats. These ships proved versatile and seaworthy. The vessels could also undertake convoy escort, anti-submarine warfare and minelaying tasks as well as minesweeping. However, the ships were very expensive and complicated to build, and their oil-fired boilers meant they suffered from the fuel s ...

Motor Launch
A Motor Launch (ML) is a small military vessel in Royal Navy service. It was designed for harbour defence and submarine chasing or for armed high-speed air-sea rescue. Some vessels for water police service are also known as motor launches. World War I service Although small by naval standards, it was larger than the preceding steam or diesel-engined harbour launches of 56ft and coastal motor boats of 40 and 55 ft length. The first motor launches entered service in the First World War. These were five hundred and eighty vessels built by the US Elco company for the Admiralty, receiving the numbers ML-1 to ML-580. They served with the Royal Navy between 1916 and the end of the war, defending the British coast from German submarines. Some of the earliest examples, including ML 1, also served in the Persian Gulf from June 1916. After the Armistice of 11 November 1918 a flotilla of 12 Royal Navy motor launches travelled down the Rhine performing duty as the Rhine Patrol F ...

Schnellboot
E-boat was the Western Allies' designation for the fast attack craft (German: ''Schnellboot'', or ''S-Boot'', meaning "fast boat") of the Kriegsmarine during World War II; ''E-boat'' could refer to a patrol craft from an armed motorboat to a large ''Torpedoboot.'' The name of E-boats was a British designation using the letter ''E'' for ''Enemy'', The main wartime production boats, the ''S-100'' class, were very seaworthy, heavily armed and capable of sustaining , briefly accelerating to . These were armed with torpedoes and Flak guns; commonly one 37 mm at the stern, one 20 mm at the bow with a twin mount amidships, plus machine guns. Armament varied and some ''S-100''s substituted a 40mm Bofors or, less commonly, a 20mm ''flakvierling'' mount for the aft 37mm cannon. The ''S-100''-class boats were long and in beam. Their diesel engines provided a range of , substantially greater than the gasoline-fueled American PT boats and British motor torpedo boats (MTBs). A ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Travemünde
Travemünde () is a borough of Lübeck, Germany, located at the mouth of the river Trave in Bay of Lübeck, Lübeck Bay. It began life as a fortress built by Henry the Lion, Duke of Saxony, in the 12th century to guard the mouth of the Trave, and the Denmark, Danes subsequently strengthened it. It became a town in 1317 and in 1329 passed into the possession of the free city of Lübeck, to which it has since belonged. Its fortifications were demolished in 1807. Travemünde has been a seaside resort since 1802, and is Germany, Germany's largest ferry port on the Baltic Sea with connections to Sweden, Finland, Russia, Latvia and Estonia. The lighthouse is the oldest on the German Baltic coast, dating from 1539. Another attraction of Travemünde is the Flying P-Liner ''Passat (ship), Passat'', a museum ship anchored in the mouth of the Trave.
