E-Boats
E-boat was the Western Allies' designation for the fast attack craft (German: ''Schnellboot'', or ''S-Boot'', meaning "fast boat"; plural ''Schnellboote'') of the Kriegsmarine of Nazi Germany 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, from ''S26'' onwards (but often designated the ''S100'' 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 ''S26'' class boats substituted a 40mm Bofors or, less commonly, a 20mm ''flakvierling'' (quadruple mount) for the aft 37mm cannon. The ''S26'' class boats – which provided the bulk of the wartime deliveries – were ... [...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, and it was valued for its maneuverability and speed. However, PT boats were 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 US Navy they were organized in Motor Torpedo Boat Squadrons (MTBRONs). The PT boat was very different from the first generation of torpedo boats, 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 di ...

Fast Attack Craft War Badge
The Fast Attack Craft War Badge or S-Boat War Badge () was a World War II German military decoration awarded to members of the ''Kriegsmarine'' for service on fast attack craft or patrol/torpedo boats. The award was instituted on 30 May 1941. Requirements to receive the award included: an outstandingly successful sortie, wounded in action, 12 sorties against enemy vessels or installations, or outstanding leadership. Description The medal was produced in two versions. The original 1941 version consisted of a "shorter high-silhouette" S-boat with an outer gold laurel wreath of oak leaves with the German Eagle at the top, while clutching a swastika. The second later version was introduced in January, 1943. It had the same basic design, but with a "longer and newer" model S-boat and a larger German Eagle at the top. The badge was worn on the lower part of the left breast pocket of the naval service tunic, underneath the 1st class Iron Cross, if awarded. Recipients of Fast Attack Cra ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull (watercraft), hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are deck (ship), decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Reichsmarine
The () 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 , 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 were then carried over into the organization of the ''Kriegsmarine''. ''Vorläufige Reichsmarine'' The () 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.

Oheka II
''Oheka II'' was a private motor yacht built for German-born American investment banking, investment banker Otto Hermann Kahn by Lürssen in 1927. Capable of 34 knot (unit), 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 Castle, Oheka. ''Oheka II'' Born in 1867 in Mannheim, Germany, Mannheim and relocated to the United States in 1893, Otto Hermann Kahn was an American-based investment banker, collecting, 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 pr ...

Motor Yacht
A yacht () is a sail- or marine propulsion, motor-propelled watercraft made for pleasure, cruising, or racing.

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 Napoleonic Wars, the First World War and the 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. See also *Irish Sea *GIUK gap The GIUK gap ...

A 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 energy, 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.

Fairmile D Motor Torpedo Boat
The Fairmile D motor torpedo boat was a type of United Kingdom, British motor torpedo boat (MTB) and motor gunboat (MGB), conceived by entrepreneur Noel Macklin of Fairmile Marine and designed by naval architect Bill Holt for the Royal Navy. Nicknamed "Dog Boats", they were designed to be assembled in kit form mass-produced by the Fairmile organisation and assembled at dozens of small boatbuilding yards around Britain, to combat the known advantages of the German Schnellboote, E-boats over previous British coastal craft designs. At 115 feet in length, 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. Boats Holt combined a destroyer style bow with a Fairmile style stern, working with Fairmile from 1940 to develop a structure suitable for pre-fabrication. There was a supply of Packard engines due to lend-Lease and these were arranged as two pairs in the engine room expected to give a ...
