S-boot
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 ...

Lürssen
Lürssen (or Lürssen Werft) is a German shipyard with headquarters in Bremen-Vegesack and shipbuilding facilities in Lemwerder, Berne and Bremen-Fähr-Lobbendorf. Lürssen designs and constructs yachts, naval ships and special vessels. Trading as Lürssen Yachts, it is one of the leading builders of custom superyachts such as Paul Allen's ''Octopus'', David Geffen's ''Rising Sun'', and Khalifa bin Zayed Al Nahyan's ''Azzam'', the second largest private yacht in the world at 180 m in length after the REV Ocean''. History On 27 June 1875 the 24 year-old Friedrich Lürssen set up a boatbuilding workshop in Aumund, a suburb of Bremen, Germany. The focus of work in the first years was on work boats for fishing and ferry operations. Hull number one was a five meter long rowboat. From the 1880s Lürssen opened up the sport boat market. In 1886 the first motorboat in the world was built by Lürssen (according to his own account).''Kölner Stadt-Anzeiger''. 16. September 2011, P ...

2 Cm Flak 30, Flak 38 And Flakvierling 38
The Flak 30 (''Flugzeugabwehrkanone 30'') and improved Flak 38 were 20 mm anti-aircraft guns used by various German forces throughout World War II. It was not only the primary German light anti-aircraft gun but by far the most numerously produced German artillery piece throughout the war. It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons onto a single carriage. Development The Germans fielded the unrelated early 2 cm Flak 28 just after World War I, but the Treaty of Versailles outlawed these weapons and they were sold to Switzerland. The original Flak 30 design was developed from the Solothurn ST-5 as a project for the Kriegsmarine, which produced the 20 mm C/30. The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the more powerful 20 mm rounds. The C/30, featuring a barrel length of 65 calibres, had a fire rate of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichsmarine
The ''Reichsmarine'' ( en, Realm Navy) was the name of the German Navy during the Weimar Republic and first two years of Nazi Germany. It was the naval branch of the ''Reichswehr'', existing from 1919 to 1935. In 1935, it became known as the ''Kriegsmarine'' (War Navy), a branch of the ''Wehrmacht''; a change implemented by Adolf Hitler. Many of the administrative and organizational tenets of the ''Reichsmarine'' were then carried over into the organization of the ''Kriegsmarine''. ''Vorläufige Reichsmarine'' The ''Vorläufige Reichsmarine'' ( en, Provisional Realm Navy) was formed after the end of World War I from the Imperial German Navy. The provisions of the Treaty of Versailles restricted the German Navy to 15,000 men and no submarines, while the fleet was limited to six pre-dreadnought battleships, six light cruisers, twelve destroyers, and twelve torpedo boats. Replacements for the outdated battleships were restricted to a maximum size of 10,000 tons. ''Reichsmarine'' T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oheka II
''Oheka II'' was a private motor yacht built for German-born American investment banker Otto Hermann Kahn by Lürssen in 1927. Capable of 34 knots top speed, she became the blueprint for the Kriegsmarine's Schnellboot. "Oheka" is an acronym of letters from Kahn's full name, Otto Herman Kahn. He had previously named his New York estate, built on Long Island between 1914 and 1919, Oheka. ''Oheka II'' Born in 1867 in Mannheim and relocated to the United States in 1893, Otto Hermann Kahn was an American-based investment banker, collector, philanthropist, and patron of the arts. Kahn approached German boatbuilder Lürssen in 1926 to build a high-speed motor launch capable of use on holidays upon both the River Rhine and the North Sea. German boat builders at the time were used to building sleek displacement hull cruising boats for the Rhine, which to create a smooth ride were round bottomed. However, the problem this creates is a greater depth in the water, and a resultant increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Approaches
The Western Approaches is an approximately rectangular area of the Atlantic Ocean lying immediately to the west of Ireland and parts of Great Britain. Its north and south boundaries are defined by the corresponding extremities of Britain. The coast of the mainland forms the eastern side and the western boundary is the 30 degree meridian, which passes through Iceland. The area is particularly important to the United Kingdom, because many of its larger shipping ports lie within it. The term is most commonly used when discussing naval warfare, notably during the First World War and Battle of the Atlantic during the Second World War in which Nazi Germany's ''Kriegsmarine'' attempted to blockade the United Kingdom using submarines (U-boats) operating in this area. Since almost all shipping to and from the United Kingdom passed through this area, it was an excellent hunting ground and had to be heavily defended.

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairmile D Motor Torpedo Boat
The Fairmile D motor torpedo boat was a type of British motor torpedo boat (MTB) and motor gunboat (MGB)Reynolds, Leonard C. ''Dog Boats at War: Royal Navy D Class MTBs and MGBs, 1939–1945.'' 2000. designed by Bill Holt and conceived by Fairmile Marine for the Royal Navy. Nicknamed "Dog Boats", they were designed to combat the known advantages of the German E-boats over previous British coastal craft designs. They were bigger than earlier MTB or motor gunboat (MGB) designs (which were typically around 70 feet) but slower, at 30 knots compared to 40 knots. History Unlike the Fairmile B designs, the Dog Boats were only produced in component form in Britain. Some were built for the RAF's Marine Branch for use in the long range air-sea rescue for downed airmen. 229 boats were built between 1942 and 1945. Many versions were produced or converted from existing boats; MGB, MTB, MA/SB, LRRC and post-war FPB. Since the Fairmile D could be fitted out with a mix of armament that gav ...

Motor Gunboat
The motor gun boat (MGB) was a small, high-speed British military vessel of the Second World War, which was armed with a mix of guns, in contrast to the physically similar motor torpedo boat (MTB), whose main offensive weapon were torpedoes. The small size of the MGBs, and their high speed, made them difficult targets for German E-boats, though, like their opponents, they were limited by heavy weather, because they did not provide a stable-enough platform to aim the guns. The large number of guns meant the crew was relatively large, numbering as high as thirty men on the largest boats. Description MGBs were extremely heavily armed for vessels of their size. Early MGBs were, nevertheless, small boats, being based on Motor Anti-Submarine Boats of 63-70 feet in length; these would later be considered 'short' boats by Coastal Forces. These were mostly equipped with one heavy weapon and numerous lighter guns. The later 71.5-feet short MGBs would sport two heavy weapon locations ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PT Boat
A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II. It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs). The PT boat was very different from the first generation of torpedo boat, which had been developed at the end of the 19th century and featured a displacement hull form. These first generation torpedo boats rode low in the water, displaced up to 300 tons, and had a top speed of . During World War I Italy, the US, and UK developed the first high-performance gasoline-powered motor torpedo boats (often with top speeds over ) and corresponding torpedo tactics, but these projects were all quickly disbanded after the Armistice.
