Japanese Ironclad Hiei
was the second and last vessel of the corvettes built for the Imperial Japanese Navy (IJN) in the 1870s. They were built in the United Kingdom because the Japanese were unable to build ironclad warships in Japan at the time. She became a training ship in 1887 and made training cruises to the Mediterranean and to countries on the edge of the Pacific Ocean. The ship returned to active duty during the First Sino-Japanese War of 1894–1895 where she was damaged during the Battle of Yalu River (1894), Battle of the Yalu River. ''Hiei'' also participated in the Battle of Weihaiwei and the Japanese invasion of Taiwan (1895), invasion of Formosa in 1895. The ship resumed her training duties after the war, although she played a minor role in the Russo-Japanese War of 1904–1905. She was reclassified as a survey ship in 1906 and was sold for ship breaking, scrap in 1912.

Empire Of Japan
The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation state that existed from the Meiji Restoration on January 3, 1868, until the Constitution of Japan took effect on May 3, 1947. From Japan–Korea Treaty of 1910, 1910 to Japanese Instrument of Surrender, 1945, it included the Japanese archipelago, the Kuril Islands, Kurils, Karafuto Prefecture, Karafuto, Korea under Japanese rule, Korea, and Taiwan under Japanese rule, Taiwan. The South Seas Mandate and Foreign concessions in China#List of concessions, concessions such as the Kwantung Leased Territory were ''de jure'' not internal parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the Japanese Instrument of Surrender, formalized surrender was issued on September 2, 1945, in compliance with the Potsdam Declaration of the Allies of World War II, Allies, and the empire's territory subsequent ...

First Sino-Japanese War
The First Sino-Japanese War (25 July 189417 April 1895), or the First China–Japan War, was a conflict between the Qing dynasty of China and the Empire of Japan primarily over influence in Joseon, Korea. In Chinese it is commonly known as the Jiawu War. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the ports of Lüshunkou (Port Arthur) and Weihaiwei, the Qing government sued for peace in February 1895 and signed the Unequal treaties, unequal Treaty of Shimonoseki two months later, ending the war. In the late 19th century, Korea remained one of China's tributary states, while Japan viewed it as a target of imperial expansion. In June 1894, the Qing government, at the request of the Korean emperor Gojong of Korea, Gojong, sent 2,800 troops to aid in suppressing the Donghak Peasant Revolution. The Japanese considered this a violation of the 1885 Convention of Tientsin, and sent an expeditionary force of 8,000 troops, which la ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or Mast (sailing), mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box, in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bot ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

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 sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, 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 from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

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 its 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 Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to ...

Edward James Reed
Sir Edward James Reed, KCB, FRS (20 September 1830 – 30 November 1906) was a British naval architect, author, politician, and railroad magnate. He was the Chief Constructor of the Royal Navy from 1863 until 1870. He was a Liberal politician who sat in the House of Commons from 1874 to 1906. Early life Edward Reed was born in Sheerness, Kent and was the son of John and Elizabeth Reed. He was a naval apprentice at Sheerness and subsequently entered the School of Mathematics and Naval Construction at Portsmouth. In 1851 he married Rosetta, the sister of Nathaniel Barnaby. Barnaby was at that time a fellow student; he would subsequently succeed Reed as Chief Constructor. In 1852 he entered employment at Sheerness Dockyard, but resigned after a disagreement with the management. He then worked in journalism, including editing the '' Mechanics' Magazine''. In 1860, Reed was appointed secretary of the newly formed Institute of Naval Architects. Naval architect In 1863, at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Armored Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, what is now generally regarded as the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), a type of powerful ironclad warships was developed, and because they had a single gun deck, the term 'frigate' was used to describe them. Later developments in ironclad ships rendered the 'frigate' designation obsolete and the term fell out of favour. During the Second World War, ...

Japanese Invasion Of Taiwan (1874)
The Japanese punitive expedition to Taiwan in 1874, referred to in Japan as the and in Taiwan and mainland China as the Mudan incident (), was a punitive expedition launched by the Japanese ostensibly in retaliation for the murder of 54 Ryukyuan sailors by Paiwan indigenous peoples near the southwestern tip of Taiwan in December 1871. In May 1874, the Imperial Japanese Army and Imperial Japanese Navy attacked the indigenous Taiwanese peoples in southern Taiwan and retreated in December after the Qing dynasty agreed to pay an indemnity of 500,000 taels, with Japan conceding that China had sovereignty over Taiwan. Some ambiguous wording in the agreed terms were later argued by Japan to be confirmation of Chinese renunciation of suzerainty over the Ryukyu Islands, paving the way for ''de facto'' Japanese incorporation of the Ryukyu in 1879. Background Mudan incident In December 1871, a Ryukyuan vessel shipwrecked on the southeastern tip of Taiwan and 54 sailors were killed ...

Russo-Japanese War
The Russo-Japanese War (8 February 1904 – 5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and the Korean Empire. The major land battles of the war were fought on the Liaodong Peninsula and near Shenyang, Mukden in Southern Manchuria, with naval battles taking place in the Yellow Sea and the Sea of Japan. Russia had pursued an expansionist policy in Siberia and the Russian Far East, Far East since the reign of Ivan the Terrible in the 16th century. At the end of the First Sino-Japanese War, the Treaty of Shimonoseki of 1895 had ceded the Liaodong Peninsula and Lüshun Port, Port Arthur to Japan before the Triple Intervention, in which Russia, Germany, and France forced Japan to relinquish its claim. Japan feared that Russia would impede its plans to establish a sphere of influence in mainland Asia, especially as Russia built the Trans-Siberian Railway, Trans-Siberian Railroad, began making inroads in K ...
