Japanese Battleship Asahi
was a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. As Japan lacked the industrial capacity to build such warships itself, the ship was designed and built in the United Kingdom. Shortly after her arrival in Japan, she became flagship of the Standing Fleet, the IJN's primary combat fleet. She participated in every major naval battle of the Russo-Japanese War of 1904–1905 and was lightly damaged during the Battle of the Yellow Sea and the Battle of Tsushima. ''Asahi'' saw no combat during World War I, although the ship participated in the Siberian Intervention in 1918. Reclassified as a coastal defence ship in 1921, ''Asahi'' was disarmed two years later to meet the terms of the Washington Naval Treaty, after which she served as a training and submarine depot ship. She was modified into a submarine salvage and rescue ship before being placed in reserve in 1928. ''Asahi'' was recommissioned in late 1937, after the start of the Second ...

Shikishima-class Battleship
The was a two-ship class of pre-dreadnought battleships built for the Imperial Japanese Navy in the late 1890s. As Japan lacked the industrial capacity to build such warships herself, they were designed and built in the UK. The ships participated in the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war. ''Hatsuse'' sank after striking two mines off Port Arthur in May 1904. ''Shikishima'' fought in the Battles of the Yellow Sea and Tsushima and was lightly damaged in the latter action, although shells prematurely exploded in the barrels of her main guns in each battle. The ship was reclassified as a coast defence ship in 1921 and served as a training ship for the rest of her career. She was disarmed and hulked in 1923 and finally broken up for scrap in 1948. Design and description Combat experience in the First Sino-Japanese War convinced the Imperial Japanese Navy of weaknesses in the Jeune Ecole naval philosophy, and Japa ...

Harvey Armour
Harvey armor was a type of steel naval armor developed in the early 1890s in which the front surfaces of the plates were case hardened. The method for doing this was known as the Harvey process, and was invented by the American engineer Hayward Augustus Harvey. This type of armor was used in the construction of capital ships until superseded by Krupp armor in the late 1890s. The Harvey United Steel Company was a steel cartel whose chairman was Albert Vickers. The year 1894 would see the ten main producers of armor plate, including Vickers, Armstrong, Krupp, Schneider, Carnegie and Bethlehem Steel, form the Harvey Syndicate. Predecessors Before the appearance of compound armor in the 1880s, armor plating was made from uniform homogeneous iron or steel plates backed by several inches of teak to absorb the shock of projectile impact. Compound armor appeared in the mid-1880s and was made from two different types of steel, a very hard but brittle high-carbon steel front ...

Battle Of Tsushima
The Battle of Tsushima (Japanese:対馬沖海戦, Tsushimaoki''-Kaisen'', russian: Цусимское сражение, ''Tsusimskoye srazheniye''), also known as the Battle of Tsushima Strait and the Naval Battle of Sea of Japan (Japanese: 日本海海戦, Nihonkai''-Kaisen'') in Japan, was a List of battles of the Russo-Japanese War, major naval battle fought between Russia and Japan during the Russo-Japanese War. It was naval history's first, and so far the last, decisive sea battle fought by modern steel battleship fleets and the first naval battle in which wireless telegraphy (radio) played a critically important role. It has been characterized as the "dying echo of the old era – for the last time in the history of naval warfare, Ship of the line, ships of the line of a beaten fleet surrendered on the high seas". It was fought on 27–28 May 1905 (14–15 May in the Julian calendar then in use in Russia) in the Tsushima Strait located between Korea and southern Japan ...

Battle Of The Yellow Sea
The Battle of the Yellow Sea ( ja, 黄海海戦, Kōkai kaisen; russian: Бой в Жёлтом море) was a major naval battle of the Russo-Japanese War, fought on 10 August 1904. In the Russian Navy, it was referred to as the Battle of 10 August. The battle foiled an attempt by the Russian fleet at Port Arthur to break out and form up with the Vladivostok squadron, forcing them to return to port. Four days later, the Battle off Ulsan similarly ended the Vladivostok group's sortie, forcing both fleets to remain at anchor. Background The Imperial Russian Navy's First Pacific Squadron, commanded by Admiral Wilgelm Vitgeft, had been trapped in Port Arthur since the Imperial Japanese Navy's blockade began on 8 February 1904 with the Battle of Port Arthur. Throughout late July and early August, as the Imperial Japanese Army laid siege to Port Arthur, relations between Admiral Vitgeft and Russian Viceroy Yevgeni Alekseyev increasingly soured. Viceroy Alekseyev, a former admiral, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russo-Japanese War
The Russo-Japanese War ( ja, 日露戦争, Nichiro sensō, Japanese-Russian War; russian: Ру́сско-япóнская войнá, Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1905 over rival imperial ambitions in Manchuria and the Korean Empire. The major theatres of military operations were located in Liaodong Peninsula and Mukden in Southern Manchuria, and the Yellow Sea and the Sea of Japan. Russia sought a warm-water port on the Pacific Ocean both for its navy and for maritime trade. Vladivostok remained ice-free and operational only during the summer; Port Arthur, a naval base in Liaodong Province leased to Russia by the Qing dynasty of China from 1897, was operational year round. Russia had pursued an expansionist policy east of the Urals, in Siberia and the Far East, since the reign of Ivan the Terrible in the 16th century. Since the end of the First Sino-Japanese War in 1895, Japan had feared Russian en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standing Fleet
The was a fleet of the Imperial Japanese Navy. It was the main combat fleet of the Japanese Navy and formed the core of a wartime Combined Fleet organization. It was created from the Standing Small-Fleet in 1889. It was split into the 1st Fleet and the 2nd Fleet in 1903. History On 24 July 1889 the Fleet Ordinance (Edict No. 100) was enacted as the first independent fleet-related decree of the Japanese Navy, and the fleet was to be composed of three or more warships. On 29 July 1889 the Standing Small-Fleet was reorganized into the Standing Fleet (commander-in-chief: Rear Admiral Inoue Yoshika). On 19 June 1894, in response to the deterioration of Japan-China relations, all fleet regulations were revised (Edict No. 71), and torpedo boats and transport vessels were attached to the fleet as specified by the Edict. The edict also stipulated that the staff should be enhanced and that ships could be dispatched outside the patrol areas. On 13 July a Guard Fleet consisting of n ...

Flagship
A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known. Over the years, the term "flagship" has become a metaphor used in industries such as broadcasting, automobiles, education, technology, airlines, and retail to refer to their highest profile or most expensive products and locations. Naval use In common naval use, the term ''flagship'' is fundamentally a temporary designation; the flagship is wherever the admiral's flag is being flown. However, admirals have always needed additional facilities, including a meeting room large enough to hold all the captains of the fleet and a place for the admiral's staff to make plans and draw up orders. Historically, only larger ships could accommodate such requirements. The term was also used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Pre-dreadnought Battleship
Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of in 1906. The pre-dreadnought ships replaced the ironclad battleships of the 1870s and 1880s. Built from steel, protected by case-hardened steel armour, and powered by coal-fired triple-expansion steam engines, pre-dreadnought battleships carried a main battery of very heavy guns in fully enclosed rotating turrets supported by one or more secondary batteries of lighter weapons. In contrast to the multifarious development of ironclad warships in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's . The similarity in appearance of battleships in the 1890s was underlined by the increasing number of ships being built. New naval powers such as Germany, Japan, the United States, and to a lesser extent Italy and Austria-Hungary, began to establish ...

Casemate
A casemate is a fortified gun emplacement or armored structure from which artillery, guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to Ancient history, antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see #Antiquity: casemate wall, Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...
