Hatsuharu-class Destroyer
The were a class of Imperial Japanese Navy destroyers in the service before and during World War II. The final two vessels in the class, completed after modifications to the design, are sometimes considered a separate "''Ariake'' class". Background The provisions of 1930 London Naval Treaty stipulated that the overall destroyer tonnage for the Imperial Japanese Navy would be capped at 105,500 tons with a maximum permissible tonnage per ship of 1,850 tons. Furthermore, only 16 percent of the overall tonnage could be of this size, with the remainder not exceeding 1,500 tons per vessel. This effectively meant that additional units of the previous and destroyers could no longer be built. The Imperial Japanese Navy responded by ordering naval architects to design ships that were lighter by at least 260 tons, and yet mount the same armament.Stille, pp. 35–38 In the end, the new class ended up with one less gun (three turrets with five 127 mm guns instead of six), with a smaller ...

Sasebo Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Sasebo Naval District was established at Sasebo, Nagasaki in 1886, as the third of the naval districts responsible for the defense of the Japanese home islands. After the establishment of the navy base, a ship repair facility was established in 1889 with a dry dock. With the addition of equipment and facilities for ship production by 1897, the "Sasebo Shipyards" were officially established, and renamed the "Sasebo Naval Arsenal" in 1903. Construction of the arsenal was supervised by the French engineer Louis-Émile Bertin. In 1913, a 250-ton crane was installed, and the shipbuilding facilities expanded to permit the construction of large warships. With the mothballing of the Maizuru Naval Arsenal due to restrictions by the Washington Naval Treaty, much of the design and prototype work for new classes of destroyers and torpedo boats formerly done at Maizuru was shifted to ...

NMS Mărăști
NMS ''Mărăști'' was one of four s ordered by Romania shortly before the beginning of the First World War from Italy. All four sister ships were requisitioned when Italy joined the war in 1915. Originally named ''Vijelie'' by the Romanians, she was renamed ''Sparviero'' in Italian service. Not completed until mid-1917, the ship engaged Austro-Hungarian ships in the Adriatic Sea only twice before the war ended in November 1918. She was given a new name as ''Mărăști'' when she was re-purchased by the Romanians in 1920. After the Axis invasion of the Soviet Union on 22 June 1941 (Operation Barbarossa), ''Mărăști'' took part in the Raid on Constanța a few days later and may have damaged a Soviet destroyer leader during the battle. The powerful Soviet Black Sea Fleet heavily outnumbered Axis naval forces in the Black Sea and the Romanian destroyers were limited to escort duties in the western half of the Black Sea during the war. In early 1944 the Soviets were able to cut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strafing
Strafing is the military practice of attacking ground targets from low-flying aircraft using aircraft-mounted automatic weapons. Less commonly, the term is used by extension to describe high-speed firing runs by any land or naval craft such as fast boats, using smaller-caliber weapons and targeting stationary or slowly-moving targets. Etymology The word is an adaptation of German ''strafen'', to punish, specifically from the humorous adaptation of the German anti-British slogan ''Gott strafe England'' (May God punish England), dating back to World War I. Description Guns used in strafing range in caliber from machine guns, to autocannon or rotary cannon. Although ground attack using automatic weapons fire is very often accompanied with bombing or rocket fire, the term "strafing" does not specifically include the last two. The term "strafing" can cover either fixed guns, or aimable (flexible) guns. Fixed guns firing directly ahead tend to be more predominant on fixed ...

Torpedo Launcher
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft Warfare
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-to-air missile, surface based, subsurface (Submarine#Armament, 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 defense, 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 World War II, Second World War, the Soviet Union, and modern NATO a ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Fourth Fleet Incident
The 4th Fleet was a fleet of the Imperial Japanese Navy. The Fourth Fleet designation was used during three separate periods. The initial designation was for a group of ships that were assigned to work together during the Russo-Japanese conflict and the period of its immediate aftermath. The second time the designation was used was during the Sino-Japanese conflict, and the third time was as a South Pacific area of command during the middle of the Pacific War. History Russo-Japanese War First established on June 14, 1905, the 4th Fleet was created after the Battle of Tsushima in the Russo-Japanese War specifically to support and cover the landings of Japanese forces in Sakhalin. Afterwards, it was sent to the United States with the Japanese delegation negotiating the Treaty of Portsmouth ending the war, and was disbanded on December 20, 1905. The Fourth Fleet incident The Fourth Fleet was temporarily resurrected during a war game exercise executed in 1935, playing the role of the ...

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
