The ''Sparviero'' class, also known as the ''Nibbio'' class, are small hydrofoil missile boats capable of traveling at speeds of . They were designed for and formerly used by the Italian Navy. The Japanese 1-go class missile boat is an updated version formerly used by the Japan Maritime Self-Defense Force (JMSDF). History Italy The ''Sparviero''-class fast attack hydrofoil was designed in Italy by the Alinavi society, a consortium of the American company Boeing, the Italian government's naval research branch, and Carlo Rodriguez, a Messina-based builder of commercial hydrofoils, based on Boeing's for the United States Navy.Gardiner and Chumbley 1995, p. 217.Baker 1998, p. 382.

La Spezia, Italy
La Spezia (, or , ; in the local Spezzino dialect) is the capital city of the province of La Spezia and is located at the head of the Gulf of La Spezia in the southern part of the Liguria region of Italy. La Spezia is the second largest city in the Liguria region, after Genoa. Located roughly midway between Genoa and Pisa, on the Ligurian Sea, it is one of the main Italian military and commercial harbours and a major Italian Navy base. A popular seaside resort, it is also a significant railway junction, and is notable for its museums, for the Palio del Golfo rowing race, and for railway and boat links with the Cinque Terre. History La Spezia and its province have been settled since prehistoric times. In Roman times the most important centre was Luni, not far from Sarzana. As the capital of the short-lived Niccolò Fieschi Signoria in the period between 1256 and 1273, La Spezia was inevitably linked with Genoese vicissitudes. After the fall of the Republic of Genoa, an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotary Cannon
A rotary cannon, rotary autocannon, rotary gun or Gatling cannon, is any large-caliber multiple-barreled automatic firearm that uses a Gatling-type rotating barrel assembly to deliver a sustained saturational direct fire at much greater rates of fire than single-barreled autocannons of the same caliber. The loading, firing and ejection functions are performed simultaneously in different barrels as the whole assembly rotates, and the rotation also permits the barrels some time to cool. The rotating barrels on nearly all modern Gatling-type guns are powered by an external force such as an electric motor, although internally powered gas-operated versions have also been developed. The cyclic multi-barrel design synchronizes the firing/reloading sequence. Each barrel fires a single cartridge when it reaches a certain position in the rotation, after which the spent casing is ejected at a different position and then a new round is loaded at another position. During the cycle, the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf War
The Gulf War was a 1990–1991 armed campaign waged by a 35-country military coalition in response to the Iraqi invasion of Kuwait. Spearheaded by the United States, the coalition's efforts against Iraq were carried out in two key phases: Operation Desert Shield, which marked the military buildup from August 1990 to January 1991; and Operation Desert Storm, which began with the aerial bombing campaign against Iraq on 17 January 1991 and came to a close with the American-led Liberation of Kuwait on 28 February 1991. On 2 August 1990, Iraq invaded the neighbouring State of Kuwait and had fully occupied the country within two days. Initially, Iraq ran the occupied territory under a puppet government known as the "Republic of Kuwait" before proceeding with an outright annexation in which Kuwaiti sovereign territory was split, with the "Saddamiyat al-Mitla' District" being carved out of the country's northern portion and the "Kuwait Governorate" covering the rest.

Uraga, Kanagawa
is a subdivision of the city of Yokosuka, Kanagawa Prefecture, Japan. It is located on the south eastern side of the Miura Peninsula, at the northern end of the Uraga Channel, at the entrance of Tokyo Bay. History With the establishment of the Tokugawa shogunate based in Edo at the start of the 17th century, the small village of Uraga developed rapidly due to its sheltered harbor and strategic location at the entrance of Edo Bay. The area was ''tenryō'' territory under direct control of the shogunate, and the increase in maritime traffic led to the development of merchant and trading firms in the area. In 1720, the shogunate established the post of '' Uraga bugyō'', whose responsibility was to police traffic and to organize coastal defenses, and the entrances to the harbor were fortified with cannon against possible incursions by foreign ships in violation of Japan’s national isolation policy. Still, in 1812, the British whaler stopped at Uraga and took on water, food, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumitomo
The is one of the largest Japanese ''keiretsu'', or business groups, founded by Masatomo Sumitomo (1585-1652) around 1615 during the early Edo period. History The Sumitomo Group traces its roots to a bookshop in Kyoto founded circa 1615 by Masatomo Sumitomo, a former Buddhist monk. Even today management of the group is guided by his "Founder's Precepts", written in the 17th century. Copper refining made the company famous. Riemon Soga, Masatomo Sumitomo's brother-in-law, learned Western methods of copper refining. In 1590 he established a smelting business, ''Izumiya'', literally meaning "spring shop". Riemon perfected techniques that allowed the extraction of silver from copper ore, something Japanese technology had not previously accomplished. The smelting and smithing business was moved from Kyoto to Osaka by the late 17th century. Soga passed control of the company to his son Tomomochi who managed its transformation into a major trading house during the Edo period. Sumitom ...

Fiscal Year
A fiscal year (or financial year, or sometimes budget year) is used in government accounting, which varies between countries, and for budget purposes. It is also used for financial reporting by businesses and other organizations. Laws in many jurisdictions require company financial reports to be prepared and published on an annual basis but generally not the reporting period to align with the calendar year (1 January to 31 December). Taxation laws generally require accounting records to be maintained and taxes calculated on an annual basis, which usually corresponds to the fiscal year used for government purposes. The calculation of tax on an annual basis is especially relevant for direct taxes, such as income tax. Many annual government fees—such as council tax and license fees, are also levied on a fiscal year basis, but others are charged on an anniversary basis. Some companies, such as Cisco Systems, end their fiscal year on the same day of the week each year: the day ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muggiano
Lerici ( lij, Lerxi, locally ) is a town and ''comune'' in the province of La Spezia in Liguria (northern Italy), part of the Italian Riviera. It is situated on the coast of the Gulf of La Spezia, southeast of La Spezia. It is known as the place where the poet Percy Bysshe Shelley drowned. The town is connected by ferry to the Cinque Terre and Portovenere. One of the main sights of Lerici is its castle which since its first founding in 1152 was used to help control the entrance of the Gulf of La Spezia. Today the castle contains a museum of palaeontology. History The origins of the town date back to the Etruscan period. In the Middle Ages the town came under Genoese control. After it had been sold to Lucca, it became involved in a series of conflicts between Genoa and Pisa, as it was on their common border. In 1479, the town came under Genoese sway for good.

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser . A variant of the HS 293 had a TV ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Pump-jet
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
