Kormoran 2-class Minehunter
Kormoran II (Cormorant class) - officially project 258, mine hunting type of vessels in building for the Polish Navy. The 2011 Defense Budget included a single vessel of this class. It was launched on 4 September 2015 and was predicted to enter service late 2016. Two more ships have been planned. Ships are built by Remontowa Shipbuilding Gdańsk and Naval Shipyard Gdynia consortium. It will be armed with 35 mm KDA anti-aircraft cannon. Construction Project 258 vessels are long and wide. The draft is and the displacement is 830 tons. Contrary to previous construction concepts of this type, the hull was made of non-magnetic steel instead of plastic. The advantage of the steel hull was, among other things, lower operating costs and higher fire resistance. The hull itself is divided into 33 sections. The ship's superstructure A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures suc ...

Oerlikon 35 Mm Twin Cannon
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves (renamed as ''Rheinmetall Air Defence AG'' following the merger with Rheinmetall in 2009). The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries. Design and development The system uses twin autocannons, firing 35×228mm NATO-standard ammunition. It was originally designated 353 MK and is now designated as the KD series. The same KD series 35mm cannons are used in the Leopard 1 based Gepard and Type 74 tank based Type 87 SPAAG and Marksman self-propelled anti-aircraft guns (SPAAG). The system could be paired with the off-gun (remote) ''Super Fledermaus'' fire control radar, which in the late 1970s was upgraded to the ''Skyguard'' system. The weapons was aimed either directly, by way of an advanced sighting system, or automatically, by locking onto the target with ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to doc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Deck
The main deck of a ship is the uppermost complete deck extending from bow to stern. A steel ship's hull may be considered a structural beam with the main deck forming the upper flange of a box girder and the keel forming the lower strength member. The main deck may act as a tension member when the ship is supported by a single wave amidships, or as a compression member Compression members are structural elements that are pushed together or carry a load; more technically, they are subjected only to axial compressive forces. That is, the loads are applied on the longitudinal axis through the centroid of the memb ... when the ship is supported between waves forward and aft. References {{reflist Nautical terminology ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Consortium
A consortium (plural: consortia) is an association of two or more individuals, companies, organizations or governments (or any combination of these entities) with the objective of participating in a common activity or pooling their resources for achieving a common goal. is a Latin word meaning "partnership", "association" or "society", and derives from ("shared in property"), itself from ("together") and ("fate"). Examples Educational The Big Ten Academic Alliance in the Midwest and Mid-Atlantic U.S., Claremont Colleges consortium in Southern California, Five College Consortium in Massachusetts, and Consórcio Nacional Honda are among the oldest and most successful higher education consortia in the World. The Big Ten Academic Alliance, formerly known as the Committee on Institutional Cooperation, includes the members of the Big Ten athletic conference. The participants in Five Colleges, Inc. are: Amherst College, Hampshire College, Mount Holyoke College, Smith College, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
