Japanese Destroyer Okinami
was a of the Imperial Japanese Navy. Design and description The ''Yūgumo'' class was a repeat of the preceding with minor improvements that increased their anti-aircraft capabilities. Their crew numbered 228 officers and enlisted men. The ships measured overall, with a beam of and a draft of . They displaced at standard load and at deep load.Whitley, p. 203 The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of for a designed speed of . The main armament of the ''Yūgumo'' class consisted of six Type 3 guns in three twin-gun turrets, one superfiring pair aft and one turret forward of the superstructure. The guns were able to elevate up to 75° to increase their ability against aircraft, but their slow rate of fire, slow traversing speed, and the lack of any sort of high-angle fire-control system meant that they were virtually useless as anti-ai ...

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yokosuka Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy, and was located at Yokosuka, Kanagawa prefecture on Tokyo Bay, south of Yokohama. History In 1866, the Tokugawa shogunate government established the ''Yokosuka Seisakusho'', a military arsenal and naval base, with the help of foreign engineers, including the French naval architect Léonce Verny. The new facility was intended to produce modern, western-style warships and equipment for the Tokugawa navy. The construction of the arsenal was an important first step for the modernization of Japan's industry. Modern buildings, an aqueduct, foundry, brick factories, technical schools to train Japanese technicians were established. After the Boshin War and the Meiji Restoration, the new Meiji government took over control of the facility in 1871, renaming it the ''Yokosuka Zosenjo'' (Yokosuka Shipyards). The first dry dock was opened in 1871, and is still in operation today. Japan's first d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
18th Infantry Regiment (Imperial Japanese Army)
The was an infantry regiment in the Imperial Japanese Army (IJA). Its call sign and unit code was . The unit was formed in 1884 and based in the city of Toyohashi as a branch of the Nagoya Garrison. Throughout its history, the majority of its soldiers came from the Mikawa region, or eastern Aichi prefecture. The regiment first deployed for the First Sino-Japanese War in 1894. In 1904, it deployed again for the Russo-Japanese War where it fought in several major battles. Between 1928 and 1936, the regiment was deployed to China where it engaged in two military operations in China, though it spent most of the time on garrison and occupation duty. With the start of the Second Sino-Japanese War in the summer of 1937, the regiment participated in the Battle of Shanghai and then participated in the major campaigns of central China. In 1944, the 18th Regiment was sent to the Pacific theater as part of the 29th Division. On the way to Saipan, the transport ship that was carryin ...

Japanese Destroyer Asashimo
was a of the Imperial Japanese Navy. She was among the several ships sunk during Operation Ten-Go by attacking US aircraft in 1945. Service career and fate On 29 February 1944, while escorting a large convoy en route to Truk, ''Asashimo'' detected the submarine making a night surface approach on the convoy. ''Rock'' fired a spread of four torpedoes from her stern tubes at the closing ''Asashimo'' without scoring a hit. Illuminated by the destroyer's searchlight, and under fire from the ship's 5-inch (130 mm) guns, ''Rock'' dived. For four hours ''Asashimo'' continued depth charge attacks, without success. That night ''Rock'' surfaced and found that her periscopes were excessively damaged and that her bridge had been riddled with shrapnel. The damage necessitated a return to Pearl Harbor for repairs. Later that night, the busy ''Asashimo'' sank the submarine . Japanese records indicate that one of their convoys, Matsu No. 1, was attacked by a submarine on 29 February 1944 ...

Anti-aircraft Gun
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraf ...

Ship Gun Fire-control System
Ship gun fire-control systems (GFCS) are analogue fire-control systems that were used aboard naval warships prior to modern electronic computerized systems, to control targeting of guns against surface ships, aircraft, and shore targets, with either optical or radar sighting. Most US ships that are destroyers or larger (but not destroyer escorts except Brooke class DEG's later designated FFG's or escort carriers) employed gun fire-control systems for and larger guns, up to battleships, such as . Beginning with ships built in the 1960s, warship guns were largely operated by computerized systems, i.e. systems that were controlled by electronic computers, which were integrated with the ship's missile fire-control systems and other ship sensors. As technology advanced, many of these functions were eventually handled fully by central electronic computers. The major components of a gun fire-control system are a human-controlled director, along with or later replaced by radar or te ...
