Japanese Cruiser Unebi
was a protected cruiser built in France for the Imperial Japanese Navy (IJN) by Forges et Chantiers de la Gironde during the 1880s as the Japanese were not yet able to build warships of her size in Japan. Completed in 1886, the ship disappeared somewhere between Singapore and Japan on her delivery voyage with the loss of all hands. Background In the early 1880s, Navy Minister Kawamura Sumiyoshi was struggling to reconcile his desire for expansion in the face of the growing Chinese Beiyang Fleet with Japan's limited financial resources. Two developments offered Kawamura a way to resolve his problems. First, the French development of the naval doctrine which emphasized the use of cheap torpedo boats and heavily armed light ships to offset an opponent's superiority in expensive, heavily armed and armored battleships. Second, the design of heavily armed, lightly protected cruisers by George Rendel of Armstrong Whitworth, as exemplified by the Chilean cruiser ''Esmerelda'', fit ...

Yamato Sanzan
or "the three mountains of Yamato", in Kashihara, Nara Prefecture, Japan, are , , and . Celebrated in Japanese poetry, they have been jointly designated a Place of Scenic Beauty. Jimmu, first Emperor of Japan, is said to have built his palace on the southeast side of Mt Unebi; he is enshrined at Kashihara Jingū. Archaeological study in the 1990s has shown that, rather than their surrounding Fujiwara-kyō on three sides, the "palace-city" was so large as to encompass the three mountains.

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are fro ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured paral ...

Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, '' standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and '' square-rigged'' vessels. Standing ...

Japanese Cruiser Izumi
The Chilean cruiser ''Esmeralda'' was the first protected cruiser, a ship type named for the arched armored deck that protected its most vital areas, including its propulsion plant and magazines. Constructed by the British shipbuilder Armstrong Mitchell in the early 1880s, ''Esmeralda'' was hailed as "the swiftest and most powerfully armed cruiser in the world" by William Armstrong, the company's founder.The 'Esmeralda,' ''Record'' (Valparaiso) 13, no. 183 (4 December 1884): 5. ''Esmeralda'' was completed in 1884, and the ship was quickly deployed to Panama in the following year to show the Chilean flag and conduct |
Armstrong Whitworth
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers. In 1927, it merged with Vickers Limited to form Vickers-Armstrongs, with its automobile and aircraft interests purchased by J D Siddeley. History In 1847, the engineer William George Armstrong founded the Elswick works at Newcastle, to produce hydraulic machinery, cranes and bridges, soon to be followed by artillery, notably the Armstrong breech-loading gun, with which the British Army was re-equipped after the Crimean War. In 1882, it merged with the shipbuilding firm of Charles Mitchell to form Armstrong Mitchell & Company and at the time its works extended for over a mile (about 2 km) along ...

Battleship
A battleship is a large armour, armored warship with a main artillery battery, battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Jeune École
The ''Jeune École'' ("Young School") was a strategic naval concept developed during the 19th century. It advocated the use of small, heavily armed vessels to combat larger battleships, and the use of commerce raiders to cripple the trade of the rival nation. The idea was developed among French naval theorists: the French government had the second largest navy of the time, and the theorists desired to counteract the strength of the larger British Royal Navy. Small units against battleships One of the first proponents of the ''Jeune École'' was the artillery general Henri-Joseph Paixhans, who invented explosive shell guns for warships during the 1820s. He advocated the use of these powerful guns on numerous small steam warships that could destroy much larger battleships. Later, the French Navy developed the concept more elaborately as it experimented with torpedoes and torpedo boats. The French Navy became one of the strongest proponents of this combat system by the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beiyang Fleet
The Beiyang Fleet (Pei-yang Fleet; , alternatively Northern Seas Fleet) was one of the four modernized Chinese navies in the late Qing dynasty. Among the four, the Beiyang Fleet was particularly sponsored by Li Hongzhang, one of the most trusted vassals of Empress Dowager Cixi and the principal patron of the "self-strengthening movement" in northern China in his capacity as the Viceroy of Zhili and the Minister of Beiyang Commerce (北洋通商大臣). Due to Li's influence in the imperial court, the Beiyang Fleet garnered much greater resources than the other Chinese fleets and soon became the dominant navy in Asia before the onset of the 1894–1895 First Sino-Japanese War. It was the largest fleet in Asia and the 8th in the world during the late 1880s in terms of tonnage. Creation The creation of the Beiyang Fleet dated back to 1871, when four ships from the southern provinces were shifted north to patrol the northern waters. The Beiyang fleet was initially considered to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
