No.1-class Auxiliary Submarine Chaser
The was a class of submarine chasers of the Imperial Japanese Navy (IJN), serving during World War II. 200 vessels were built under the Maru KyĆ« Programme (Ship # 500â599) and the Maru Sen Programme (Ship # 2001â2100). Background In 1939 the Imperial Japanese Navy had two diesel-engined harbour tugs built, ''No.1182'' and ''No.1183''. (Other contemporary Japanese harbour tugs were powered by compound steam engines). They had wooden hulls and were designed so that they could be converted to fishing boats after hostilities ended.Jentschura ''et al'' 1977, p. 217. The two tugs, which were completed in 1940,Jentschura ''et al'' 1977, p. 267 formed the basis for a class of auxiliary subchasers. The IJN evaluated them, confirmed that they were effective subchasers, and in 1941, ordered 100 vessels. Their wartime performance was good, but they were always troubled by insect damage because their hull was wooden. Those that survived the war played an active part in the sweeping ...

Kure Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Kure Naval District was established at Kure, Hiroshima in 1889, as the second of the naval districts responsible for the defense of the Japanese home islands. Along with the establishment of the navy base, a ship repair facility was also constructed, initially by moving the equipment from the Onohama shipyards near Kobe. Construction was supervised by the French engineer Louis-Ămile Bertin. The first warship constructed at Kure, '' Miyako'', was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903. Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles. The battleships ''Yamato'' and '' Nagato'' were designed and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ensign Of The People's Republic Of China
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

HMS Tally-Ho (P317)
HMS ''Tally-Ho'' was a British submarine of the third group of the T class. She was built as ''P317'' by Vickers Armstrong, Barrow and launched on 23 December 1942. She has been the only ship of the Royal Navy to bear the name, that of the hunting call, "Tally-Ho!". Second World War service While commanded by Captain Leslie W. A. Bennington, ''Tally-Ho'' served in the Far East for much of her wartime career, where she sank thirteen small Japanese sailing vessels, a Japanese coaster, the Japanese water carrier ''Kisogawa Maru'', the Japanese army cargo ships ''Ryuko'' and ''Daigen Maru No.6'', the Japanese auxiliary submarine chaser '' Cha 2'', and the Japanese auxiliary minelayer ''Ma 4''. She also damaged a small Japanese motor vessel, and laid mines, one of which damaged the Japanese merchant tanker ''Nichiyoku Maru''. On 11 January 1944, ''Tally-Ho'', then based out of Trincomalee, Ceylon spotted the Japanese light cruiser and destroyer on anti-submarine warfare exer ...

Minesweeping
Minesweeping is the practice of the removal of explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. Minesweeping has been practiced since the advent of naval mining in 1855 in the Crimean War. The first minesweepers date to that war and consisted of British rowboats trailing grapnels to snag the mines. By ship A sweep is either a contact sweep, a wire dragged through the water by one or two ships to cut the mooring wire of floating mines, or a distance sweep that mimics a ship to detonate the mines. The sweeps are dragged by minesweepers, either purpose-built military ships or converted trawlers. Each run covers between , and the ships must move slowly in a straight line, making them vulnerable to enemy fire. This was exploited by the Turkish army in the Battle of Gallipoli in 1915, when mobile howitzer batteries prevented the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countriesâincluding all of the great powersâforming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Chaser
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German submarines in World War I, and Japanese and German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class was built for World War II. Also in World War II, larger PC-461-class submarine chasers used the PC hull classification symbol (for Patrol, Coastal).Gardiner and Chesneau, pp. 71, 152-154 Class relationships: * 438 (98t, wooden hull) * 343 (450t, steel hull) * 68 (850t, steel hull) ** used in similar ro ...
