''K VI'' was a patrol submarine of the Royal Netherlands Navy. The ship was built by ''Fijenoord'' shipyard in Rotterdam Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"Ne .... Service history The submarine was laid down in Rotterdam at the shipyard of ''Fijenoord'' on 4 April 1916. The launch took place on 23 December 1920. On 11 October 1921 the ship was commissioned in the Dutch navy. 27 October 1921 ''K VI'' left the port of Den Helder for the Dutch East Indies her theater of operations. She made the journey without an escort. The route she took made stops at Port Said, the Suez Canal, Sabang to Surabaya, where she arrived on 31 January 1922. In 1935 ''K VI'' was removed from active service and in August 1937 decommissioned. References External linksDescription of ship ...

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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Motor
An electric motor is an 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 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, 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 or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled. Standardized motors pr ...

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 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. 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 the submarine into the sea at the ambient ...

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 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 navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

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. Secondar ...

Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction ...

Den Helder
Den Helder () is a municipality and a city in the Netherlands, in the province of North Holland. Den Helder occupies the northernmost point of the North Holland peninsula. It is home to the country's main naval base. From here the Royal TESO ferryboat service operates the transportation link between Den Helder and the nearby Dutch Wadden island of Texel to the north. Etymology Before the year 1928 the official name of Den Helder was Helder. The origin of the name Helder is not entirely clear. The name Helder may have come from ''Helle/Helde'', which means "hill" or "hilly grounds", or from ''Helre'', which means a sandy ridge. Another explanation is that the name derived from ''Helsdeur'' (Hell's Door), likely because in the water between Den Helder and Texel (called Marsdiep) the current was so strong that many ships were lost. History Huisduinen was the original older part of the city, whereas Helder itself was a nearby smaller hamlet. When a harbour was built near ...

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the st ...

Port Said
Port Said ( ar, بورسعيد, Būrsaʿīd, ; grc, Πηλούσιον, Pēlousion) is a city that lies in northeast Egypt extending about along the coast of the Mediterranean Sea, north of the Suez Canal. With an approximate population of 603,787 (2010), it is the fifth-largest city in Egypt. The city was established in 1859 during the building of the Suez Canal. There are numerous old houses with grand balconies on all floors, giving the city a distinctive look. Port Said's twin city is Port Fuad, which lies on the eastern bank of the Suez Canal. The two cities coexist, to the extent that there is hardly any town centre in Port Fuad. The cities are connected by free ferries running all through the day, and together they form a metropolitan area with over a million residents that extends both on the African and the Asian sides of the Suez Canal. The only other metropolitan area in the world that also spans two continents is Istanbul. Port Said acted as a global city sinc ...

Suez Canal
The Suez Canal ( arz, قَنَاةُ ٱلسُّوَيْسِ, ') is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. The long canal is a popular trade route between Europe and Asia. In 1858, Ferdinand de Lesseps formed the Suez Canal Company for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the North Atlantic and northern Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , or 10 days at to 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. In 2021, more than 20,600 vessels traversed the canal (an average of 56 per day) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
