Sasebo Naval District
was the third of five main administrative districts of the pre-war Imperial Japanese Navy. Its territory included the western and southern coastline of Kyūshū, the Ryukyu Islands, Taiwan and Korea, as well as patrols in the East China Sea and the Pacific Sasebo also contained the Sasebo Naval Arsenal, specializing mostly in destroyers and smaller warships; and its anchorage was one of the largest in Japan. The District encompassed anchorages at Imari and Hirado ports as well as the designated third echelon naval ports of Takeshiki ( Tsushima), Kagoshima, Kuji ( Amami-Ōshima), and Wakamatsu (Gotō Islands) History The location of Sasebo facing China and Korea, and near the foreign treaty port of Nagasaki was recognized of strategic importance by the leaders of the early Meiji government and early Imperial Japanese Navy. In 1883, the then Lieutenant Commander Tōgō Heihachirō nominated what was a tiny fishing village as the ideal location for a naval base. With the formation ...

Treaty Port
Treaty ports (; ja, 条約港) were the port cities in China and Japan that were opened to foreign trade mainly by the unequal treaties forced upon them by Western powers, as well as cities in Korea opened up similarly by the Japanese Empire. Chinese treaty ports The British established their first treaty ports in China after the First Opium War by the Treaty of Nanking in 1842. As well as ceding the island of Hong Kong to the United Kingdom in perpetuity, the treaty also established five treaty ports at Shanghai, Canton (Guangzhou), Ningpo (Ningbo), Foochow (Fuzhou), and Amoy (Xiamen). The following year the Chinese and British signed the Treaty of the Bogue, which added provisions for extraterritoriality and the most favored nation status for the latter country. Subsequent negotiations with the Americans (1843 Treaty of Wanghia) and the French (1844 Treaty of Whampoa) led to further concessions for these nations on the same terms as the British. The second group of treaty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Frontier
Sea Frontiers were several, now disestablished, commands of the United States Navy as areas of defense against enemy vessels, especially submarines, along the U.S. coasts. They existed from 1 July 1941 until in some cases the 1970s. Sea Frontiers generally started at the shore of the United States and extended outwards into the sea for a nominal distance of two hundred miles. As early as 1927 the Navy's plans for the coastal defense of the United States and its Territories and possessions provided for the establishment of Naval Coastal Frontiers that would be larger operational commands than the individual Naval Districts.HyperWarFederal Records of World War II Volume II Military Records Part Four, 1083 On 1 July 1941, the Chief of Naval Operations formally established several Naval Coastal Frontiers; on 6 February 1942, these were renamed Sea Frontiers. Each Frontier was a geographic area, usually comprising a number of Naval Districts but including in addition the outer shipping ...

Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for naval gunfire support, shore bombardment and anti-aircraft roles. The term generally refers to tube-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire, fire-throwers. From the late Middle Ages onwards, warships began to carry cannon, cannons of various calibres. The Mongol invasion of Java introduced cannons to be used in naval warfare (e.g. Cetbang by the Majapahit). The Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Shipyard
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles. Countries with large shipbuilding industries include Australia, Brazil, China, Croatia, Denmark, Finland, France, Germany, India, Ireland, Italy, Japan, the Netherlands, Norway, the Philippines, Poland, Romania, Russia, Singapore, South Korea, Sweden, Taiwan, Turkey, the United Arab Emirates, Ukraine, the United Kingdom, the United States and Vietnam. The shipbuilding industry is more fragmented in Europe than in Asia where countries tend to have fewer, larger companies. Many naval vessels ar ...

Emperor Meiji
, also called or , was the 122nd emperor of Japan according to the traditional order of succession. Reigning from 13 February 1867 to his death, he was the first monarch of the Empire of Japan and presided over the Meiji era. He was the figurehead of the Meiji Restoration, a series of rapid changes that witnessed Japan's transformation from an isolationist, feudal state to an industrialized world power. At the time of Emperor Meiji's birth in 1852, Japan was a feudal pre-industrial country dominated by the isolationist Tokugawa shogunate and the ''daimyō'' subject to it, who ruled over the country's 270 decentralized domains. By the time of his death, Japan had undergone an extensive political, economic, and social revolution and emerged as one of the great powers on the world stage. ''The New York Times'' summarized this transformation at the emperor's funeral in 1912: "the contrast between that which preceded the funeral car and that which followed it was striking indeed. ...

Warship
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations. In wartime, the distinction between warships and merchant ships is often blurred. In war, merchant ships are often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service and not unusual for more than half a fleet to be composed of merchant ships. Until the threat of piracy subsided in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Tōgō Heihachirō
Marshal-Admiral Marquis , served as a '' gensui'' or admiral of the fleet in the Imperial Japanese Navy and became one of Japan's greatest naval heroes. He claimed descent from Samurai Shijo Kingo, and he was an integral part of preserving Japanese artwork. As Commander-in-Chief of the Combined Fleet during the Russo-Japanese War of 1904–1905, he successfully confined the Russian Pacific naval forces to Port Arthur before winning a decisive victory over a relieving fleet at Tsushima in May 1905. Western journalists called Tōgō "the Nelson of the East". He remains deeply revered as a national hero in Japan, with shrines and streets named in his honour. Early life Tōgō was born as Tōgō Nakagoro (仲五郎) on 27 January 1848 in the Kajiya-chō ( 加治屋町) district of the city of Kagoshima in Satsuma domain (modern-day Kagoshima Prefecture), to a noble family in feudal Japan, the third of four sons of Togo Kichizaemon, a samurai serving the Shimazu daimyō as ...
