Kursk Submarine Disaster
The Russian nuclear submarine sank in an accident on 12 August 2000 in the Barents Sea, with the loss of all 118 personnel on board. The submarine, which was of the Project 949A-class (Oscar II class), was taking part in the first major Russian naval exercise in more than 10 years. The crews of nearby ships felt an initial explosion and a second, much larger explosion, but the Russian Navy did not realise that an accident had occurred and did not initiate a search for the vessel for over six hours. The submarine's emergency rescue buoy had been intentionally disabled during an earlier mission and it took more than 16 hours to locate the submarine, which rested on the ocean floor at a depth of . Over four days, the Russian Navy repeatedly failed in its attempts to attach four different diving bells and submersibles to the escape hatch of the submarine. Its response was criticised as slow and inept. Officials misled and manipulated the public and news media, and refused help ...

Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

NORSAR
NORSAR is a foundation established in 1968 as part of the Norwegian- US agreement for the detection of earthquakes and nuclear explosions. The name derives from the foundation's original project, the Norwegian Seismic Array. Description Located at Kjeller, north of Oslo, NORSAR runs and maintains seismic arrays in Norway and it is the designated Norwegian National Data Centre for the Comprehensive Nuclear Test Ban Treaty. NORSAR conducts basic seismological research, develops software and provides consultancy for the petroleum industry. NORSAR was the first non-US site included in ARPANET in June 1973. Its connection went via the Tanum Earth Station in Sweden to the Seismic Data Analysis Center (SDAC) in Virginia, United States. In turn, NORSAR provided the connection point for ARPANET to spread to Peter Kirstein's research group at University College London (UCL) the following month in July 1973. Connecting through NORSAR, the Norwegian Defence Research Establishment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismometer
A seismometer is an instrument that responds to ground displacement and shaking such as caused by quakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper (see picture) or film, now recorded and processed digitally—is a ''seismogram''. Such data is used to locate and characterize earthquakes, and to study the internal structure of Earth. Basic principles A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected. The relative motion between the weight (called the mass) and the frame provides a measurement of the vertical ground motion. A rotating drum is attached to the frame and a pen is attached to the weight, thus recording any ground motion in a seismogram. Any movement from the ground moves the frame. The mass tends ...

Starboard
Port and starboard are Glossary of nautical terms (M-Z), nautical terms for watercraft and spacecraft, referring respectively to the left and right sides of the vessel, when aboard and facing the Bow (watercraft), bow (front). Vessels with bilateral Symmetry (geometry), symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side; it is usually only on the port side (hence the name). Side Port side and starboard side respectively refer to the left and right sides of the vessel, when aboard and facing the bow. The port and starboard sides of the vessel always refer to the same portion of the vessel's structure, and do not depend on the position of someone aboard the vessel. The port side is the side to the left of an observer aboard the vessel and , towards the direction the vessel is heading when underway in the forward direction. The starboard side is to the right of such an obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Torpedo#Classes and diameters, torpedoes of other classes and diameters have been used. 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 ...

Dummy Torpedo
Dummies and decoys are fake military equipment that are intended to deception, deceive the enemy. Dummies and decoys are only one aspect of military deception. Examples During World War II, dummy airfields and even towns were used in England to divert German bombers from the real targets. At the Battle of La Ciotat in 1944, American aircraft dropped hundreds of dummy paratroopers (Paradummy, paradummies) just north of La Ciotat, France. The goal of this operation was to divert German troops away from the main landing zones of Operation Dragoon. Additionally, during World War II, Operation Quicksilver (WWII), Operation Quicksilver was an attempt to mislead the Germans as to the location of the D-Day invasion using dummy military equipment.A naval example was the British battleship HMS Centurion (1911), HMS ''Centurion''. Obsolete and disarmed by World War II, she spent two years in the Mediterranean fitted with wooden guns, to make British naval forces in the area seem stronger than ...

RPK-6 Vodopad/RPK-7 Veter
RPK-6 ''Vodopad'' (, "waterfall") is a Soviet 533 mm anti-submarine missile deployed operationally since 1981. RPK-7 ''Veter'' (, "wind") is a 650 mm version, deployed operationally since 1984. Both missiles are given the same United States Navy designation SS-N-16 and NATO designation ''Stallion''. Both missiles are torpedo-tube launched, with a solid-fuel rocket engine to power them above the surface. Theys are dual-role and can be armed with either a 400 mm anti-submarine torpedo or a nuclear depth charge.

Northern Fleet
The Northern Fleet (, ''Severnyy flot'') is the Naval fleet, fleet of the Russian Navy in the Arctic. According to the Russian ministry of defence: "The Northern Fleet dates its history back to a squadron created in 1733 to protect the territories of the Russian Empire, sea trade routes and fisheries in the White Sea near the coast of the Kola Peninsula. The order of the Commander-in-Chief of the Russian Navy of 25 May 2014 determined 1733 as the year of foundation of the Northern Fleet, and June 1 as its annual holiday". In its modern iteration, the Arctic Ocean Flotilla of the former Imperial Navy evolved into a full fleet of the Soviet Navy in 1933 as the Northern Flotilla. After being awarded the Order of the Red Banner in 1965, it was officially known as the Red Banner Northern Fleet. During the Soviet era the Northern Fleet operated more than 200 submarines, ranging from diesel-electric submarine, diesel-electric to Nuclear submarine, nuclear-powered Ballistic missile s ...

Dissolution Of The Soviet Union
The Soviet Union was formally dissolved as a sovereign state and subject of international law on 26 December 1991 by Declaration No. 142-N of the Soviet of the Republics of the Supreme Soviet of the Soviet Union. Declaration No. 142-Н of the Soviet of the Republics of the Supreme Soviet of the Soviet Union, formally establishing the dissolution of the Soviet Union as a state and subject of international law. It also brought an end to the Soviet Union's federal government and General Secretary (also President) Mikhail Gorbachev's effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of 15 top-level republics that served as the homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
