Italian Submarine Ciro Menotti
''Ciro Menotti'' was one of four built for the (Royal Italian Navy) during the late 1920s. Completed in 1929, she played a minor role in the battle of Malaga during the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists. ''Ciro Menotti'' carried out a number of resupply missions during World War II. Design and description The ''Bandiera'' class was an improved and enlarged version of the preceding s. They displaced surfaced and submerged. The submarines were long, had a beam of and a draft of . They had an operational diving depth of . Their crew numbered 53 officers and enlisted men.Chesneau, p. 307 For surface running, the boats were powered by two diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the ''Bandiera'' class had a range of at ; submerged, they had a range of at .Bagnasco, p. 143 The boats were armed with ei ...

Kingdom Of Italy
The Kingdom of Italy (, ) was a unitary state that existed from 17 March 1861, when Victor Emmanuel II of Kingdom of Sardinia, Sardinia was proclamation of the Kingdom of Italy, proclaimed King of Italy, until 10 June 1946, when the monarchy was abolished, following civil discontent that led to an 1946 Italian institutional referendum, institutional referendum on 2 June 1946. This resulted in a modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the . That process was influenced by the House of Savoy, Savoy-led Kingdom of Sardinia (1720–1861), Kingdom of Sardinia, which was one of Italy's legal Succession of states, predecessor states. In 1866, Italy Third Italian War of Independence, declared war on Austrian Empire, Austria in Italo-Prussian Alliance, alliance with Kingdom of Prussia, Prussia and, upon its victory, received the region of Veneto.

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 ...

Mail Steamer
Packet boats were medium-sized boats designed mainly for domestic mail and freight transport in European countries and in North American rivers and canals. Eventually including basic passenger accommodation, they were used extensively during the 18th and 19th centuries, and had regularly scheduled services. In the 18th century, packet boats were put into use on the Atlantic Ocean between Great Britain and its colonies, where the services were called the packet trade. In the later 19th century, steam-driven packets were used extensively in the United States on the Mississippi and Missouri rivers, supplying forts and trading posts. History Packet craft were used extensively in European coastal mail services since the 17th century, and gradually added minimal passenger accommodation: "firing" (i.e. a place to cook), drinking water (often tasting of indigo or tobacco, which the water casks had previously held), and a place to sleep. Scheduled services began to be offered, but the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Spanish Republic
The Spanish Republic (), commonly known as the Second Spanish Republic (), was the form of democratic government in Spain from 1931 to 1939. The Republic was proclaimed on 14 April 1931 after the deposition of Alfonso XIII, King Alfonso XIII. It was dissolved on 1 April 1939 after surrendering in the Spanish Civil War to the Nationalist faction (Spanish Civil War), Nationalists led by General Francisco Franco. After the proclamation of the Republic, Provisional Government of the Second Spanish Republic, a provisional government was established until December 1931, at which time the Spanish Constitution of 1931, 1931 Constitution was approved. During the subsequent two years of constitutional government, known as the First Biennium, Reformist Biennium, Manuel Azaña's executive initiated numerous reforms. In 1932 religious orders were forbidden control of schools, while the government began a large-scale school-building project. A moderate agrarian reform was carried out. Home r ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

Shipyard
A shipyard, also called a dockyard or boatyard, is a place where ships are shipbuilding, built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Compared to shipyards, which are sometimes more involved with original construction, dockyards are sometimes more linked with maintenance and basing activities. The terms are routinely used interchangeably, in part because the Shipyard#History, evolution of dockyards and shipyards has often caused them to change or merge roles. Countries with large shipbuilding industries include Australia, Brazil, China, Croatia, Denmark, Finland, France, Germany, India, Republic of Ireland, Ireland, Italy, Japan, the Netherlands, Norway, the Philippines, Poland, Romania, Russia, Singapore, South Korea, Sweden, Taiwan, Turkey, the United Arab Emirates, Ukraine, the United Kingdom, the United States and Vietnam.

Laid Down
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are launching, commissioning, and decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication" and is the ceremonial beginning of the ship's life, although s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft Warfare
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface (Submarine#Armament, submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense, Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conning Tower
A conning tower is a raised platform on a ship or submarine, often armoured, from which an officer in charge can conn (nautical), conn (conduct or control) the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as is practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruiser, armoured cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield j ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 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 large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
