Hatsuse
was a pre-dreadnought battleship built for the 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, Potsdam Declaration, when it was dissolved followin ... (IJN) in the late 1890s. As Empire of Japan, Japan lacked the industrial capacity to build such warships, the ship was designed and built in the United Kingdom. She participated in the early stages of the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war, as the flagship of the 1st Division. ''Hatsuse'' was involved in the subsequent naval operations until she sank in a Russian minefield off Lüshunkou District, Port Arthur on 15 May 1904 after the ship struck two naval mine, mines. The ship struck one mine which caused significant damage. Less than two hours later, the ship struck a second mine which detonated ...

Battle Of Port Arthur
The of 8–9 February 1904 marked the commencement of the Russo-Japanese War. It began with a surprise night attack by a squadron of Imperial Japanese Navy, Japanese destroyers on the neutral country, neutral Imperial Russian Navy, Russian fleet anchored at Lüshunkou, Port Arthur, Manchuria, and continued with an List of battles of the Russo-Japanese War, engagement the following morning; further skirmishing off Port Arthur would continue until May 1904. The attack ended inconclusively. Background The opening stage of the Russo-Japanese War began with pre-emptive strikes by the Imperial Japanese Navy (IJN) against the Russian Pacific Fleet based at Lüshunkou, Port Arthur and at Incheon, Chemulpo.

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, Tyne and Wear, Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong, 1st Baron Armstrong, 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 John Siddeley, 1st Baron Kenilworth, J D Siddeley. History In 1847, the engineer William George Armstrong founded the Elswick, Tyne and Wear, 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 Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive 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.

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 ...

Naval Rating
In military terminology, a rate or rating (also known as bluejacket in the United States) is a junior enlisted sailor in a navy who is below the military rank of warrant officer. Depending on the country and navy that uses it, the exact term and the range of ranks that it refers to may vary. Royal Navy In the Royal Navy (RN) and other navies in the Commonwealth, ''rate'' and ''rating'' are interchangeably used to refer to an enlisted sailor who is ranked below warrant officers and commissioned officers, but may include petty officers and chief petty officers. Specifically, ''rate'' is the term used to describe generically all members of all ranks below a warrant officer; whereas ''rating'' is part of the official name of individual specific ranks, such as Able Rating and Leading Rating. The term comes from the general nautical usage of 'rating', to refer to a seaman's class or grade as recorded in the ship's books. The system of conferring authority on sailors i ...

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 Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...
