O 12-class Submarine
The ''O 12''-class submarine consisted of four submarines built for the Royal Netherlands Navy. The ships, with a diving depth of , were used for patrols in the Dutch home waters. The class comprised ''O 12'', ''O 13'', ''O 14'' and ''O 15''. ''O 12'' entered German service in 1943 as ''UD-2''. Construction The ships were built by two shipyards. ''O 12'', ''O 13'' and ''O 14'' were built by Koninklijke Maatschappij De Schelde Damen Naval is a Dutch shipyard, and a continuation of the Koninklijke Maatschappij De Schelde, responsible for a number of ships used by the Royal Netherlands Navy.

Koninklijke Maatschappij De Schelde
Damen Naval is a Dutch shipyard, and a continuation of the Koninklijke Maatschappij De Schelde, responsible for a number of ships used by the Royal Netherlands Navy. It is owned by the Damen Group. Damen Naval is situated in Vlissingen. History The company was founded October 8, 1875, as the ''NV Koninklijke Maatschappij De Schelde'' (KMS) after shipbuilder Arie Smit had taken over the ''Marine Etablissement'' the wharf owned by the Dutch navy. Besides shipbuilding and repair, the company also builds machines, engines, steam turbines, airplanes, and light-metal products. Koninklijk is a royal title granted by the Dutch Crown. In 1965 the company merged with the NV Rotterdamsche Droogdok Maatschappij (RDM) and the NV Motorenfabriek Thomassen of De Steeg, which resulted in the founding, on March 4, 1966, of the Rijn-Schelde Machinefabrieken en Scheepswerven NV (RSMS). Pressured by the Dutch government the Verolme Verenigde Scheepswerven NV was added, and this was the start of Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilton-Fijenoord
Wilton-Fijenoord was a shipbuilding and repair company in Schiedam the Netherlands from 1929 to 1999. Presently, the shipyard of Wilton-Feijnoord is part of Damen Shiprepair Rotterdam. Merger of Wilton and Fijenoord (1929) Wilton-Fijenoord had two predecessors. Wilton's Dok- en Werf Maatschappij was the biggest predecessor of Wilton-Fijenoord, the other was the Shipyard Fijenoord. By the mid 1920s these shipyards had become rather similar. Wilton still had an advantage in ship repair, and Fijenoord was still ahead in ship construction, especially for the navy. The idea for a merger dated as far back as at least 1927. The rationale was that the still profitable Wilton company had a major overcapacity and was spread over two locations. The activities of Fijenoord could just as well be done in Schiedam. A concentration of the combined activities in Schiedam would lead to major cost savings. In 1929 talks led to an agreement for a financial merger between the companies. Shares in Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O 9-class Submarine
The ''O 9''-class submarine consisted of three submarines, built for the Royal Netherlands Navy. Used for patrols in the Dutch home waters. The class comprised ''O 9'', ''O 10'', and ''O 11''. Its diving depth was . Design The O 9-class submarines were designed by J.J. van der Struyff, at the time chief engineer of the Royal Netherlands Navy (RNN).Jalhay (1982), p. 113. Together with the submarines of the K XI class they were the first submarines designed fully in-house by the RNN, which resulted in the first indigenous Dutch submarine design. The submarines of the O 9-class were the first Dutch submarines built with two propellers and a double hull.Mark (1997), p. 78. Previous classes only had a single hull and one propeller. As a result the submarines of the O 9-class had a different external shape in comparison to previous Dutch submarine classes as they were no longer cigar shaped. The submarines had a length of 54.66 meters, a beam of 5.70 meters and a draught ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

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 ...

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. Secondary na ...
