Ayanami-class Destroyer
The ''Ayanami'' class was a destroyer class built for the Japan Maritime Self-Defense Force (JMSDF) in the late 1950s. The primary purpose was anti-submarine warfare, so this class was classified as "DDK" (hunter-killer anti-submarine destroyer) unofficially. Design This class adopted a "long forecastle" design with inclined afterdeck called "Holland Slope", named after the scenic sloping street in Nagasaki City. Their steam turbine propulsion systems were similar to the ones of the , but they varied between each ship in the class as part of the JMSDF's attempt to find the best propulsion system for its future surface combatants. The ''Ayanami'' class were the first JMSDF vessels equipped with six 3-inch/50 caliber Mark 22 guns with Mark 33 dual mounts and Mark 32 lightweight torpedo A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groups Of Traditional Buildings
is a Japanese category of historic preservation introduced by a 1975 amendment of the law which mandates the protection of groups of traditional buildings which, together with their environment, form a beautiful scene. They can be post towns, castle towns, mining towns, merchant quarters, ports, farming or fishing villages, etc. The Japanese government's Agency for Cultural Affairs recognizes and protects the country's cultural properties under the Law for the Protection of Cultural Properties. Municipalities can designate items of particular importance as and approve measures to protect them. Items of even higher importance are then designated by the central government. The Agency for Cultural Affairs then provides guidance, advice, and funds for repairs and other work. Additional support is given in the form of preferential tax treatment. As of May 31, 2021, 126 districts have been classified as Important Preservation Districts for Groups of Traditional Buildings. List of Imp ...
