Kamikaze-class Destroyer (1905)
The were a class of thirty-two torpedo boat destroyers (TBDs) of the Imperial Japanese Navy. The ''Kamikaze'' class of destroyers were the first destroyers to be mass-produced in Japan. The class is also sometimes referred to as the ''Asakaze'' class. This class of destroyer should not be confused with the later ''Kamikaze''-class destroyers built in 1922, which participated in the Pacific War. Background The ''Kamikaze''-class destroyers were part of the 1904 Imperial Japanese Navy Emergency Expansion Program created by the outbreak of the Russo-Japanese War. Twenty-five vessels were ordered in 1904; an additional four vessels were ordered in 1905, and three more in 1906, bringing the total to thirty-two ships. The Japanese governmental shipyards were overwhelmed with the volume of construction, and for the first time civilian shipyards were also assigned to produce warships. Design In terms of design, the ''Kamikaze''-class ships were substantially identical to the previous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yokosuka Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy, and was located at Yokosuka, Kanagawa prefecture on Tokyo Bay, south of Yokohama. History In 1866, the Tokugawa shogunate government established the ''Yokosuka Seisakusho'', a military arsenal and naval base, with the help of foreign engineers, including the French naval architect Léonce Verny. The new facility was intended to produce modern, western-style warships and equipment for the Tokugawa navy. The construction of the arsenal was an important first step for the modernization of Japan's industry. Modern buildings, an aqueduct, foundry, brick factories, technical schools to train Japanese technicians were established. After the Boshin War and the Meiji Restoration, the new Meiji government took over control of the facility in 1871, renaming it the ''Yokosuka Zosenjo'' (Yokosuka Shipyards). The first dry dock was opened in 1871, and is still in operation today. Japan's first d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Laid Down
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanji
are the logographic Chinese characters taken from the Chinese family of scripts, Chinese script and used in the writing of Japanese language, Japanese. They were made a major part of the Japanese writing system during the time of Old Japanese and are still used, along with the subsequently-derived syllabic scripts of ''hiragana'' and ''katakana''. The characters have Japanese pronunciation, pronunciations; most have two, with one based on the Chinese sound. A few characters were invented in Japan by constructing character components derived from other Chinese characters. After World War II, Japan made its own efforts to simplify the characters, now known as shinjitai, by a process similar to China's simplified Chinese characters, simplification efforts, with the intention to increase literacy among the common folk. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characte ...

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Kaiserliche Marine
{{italic title The adjective ''kaiserlich'' means "imperial" and was used in the German-speaking countries to refer to those institutions and establishments over which the ''Kaiser'' ("emperor") had immediate personal power of control. The term was used particularly in connexion with the Roman-German Emperor as sovereign of the Holy Roman Empire and with the subsequent Empire of Austria. In the Early Modern Period the term is linked with the universal precedence of the ''Kaiser'' over the other princes of the realm. Holders of an imperial or ''kaiserliche'' office were recruited from the whole empire, and had wide-ranging privileges in the territories. Examples of military, political and cultural institutions with ''kaiserliche'' players in the Holy Roman Empire are the: * ''Kaiserliche Armee'' ( Imperial Army) and * ''Kaiserliche Reichspost'' (Imperial Post Office) of the Roman-German Emperor (to 1806) (Habsburg, only 1742–1745 Wittelsbach) * ''kaiserliches Hofgestüt'' (Im ...

Battle Of Tsingtao
The siege of Tsingtao (or Tsingtau) was the attack on the German port of Tsingtao (now Qingdao) in China during World War I by Japan and the United Kingdom. The siege was waged against Imperial Germany between 27 August and 7 November 1914. The siege was the first encounter between Japanese and German forces, the first Anglo-Japanese operation of the war, and the only major land battle in the Asian and Pacific theatre during World War I. Background Throughout the late 19th and early 20th centuries, Germany joined other European powers in a scramble for colonial possessions. As with the other world powers (including the United States and Japan), Germany began to interfere in Chinese local affairs. After two German missionaries were killed in the Juye Incident in 1897, China was forced to agree to the Kiautschou Bay concession in Shantung (now Shandong) to Germany in 1898 on a 99-year lease. Germany then began to assert its influence across the rest of the province and buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
