HMS Saracen (P247)
HMS ''Saracen'' was a third-batch S-class submarine built for the Royal Navy during the Second World War. Completed in 1942, ''Saracen'' conducted a patrol in the North Sea where she sank a German U-boat. She was then assigned to the 10th Submarine Flotilla in Malta, from where she made three patrols; on her second, she sank an Italian submarine. ''Saracen'' was then reassigned to the 8th Submarine Flotilla, based in Algiers, French North Africa. Operating from there, she conducted six patrols, sinking seven ships and landing agents in Corsica and Sardinia. On her twelfth patrol, ''Saracen'' was heavily damaged by two depth charge attacks from Italian destroyers. On 13 August 1943, ''Saracen'' was detected by two Italian corvettes and again attacked with depth charges. With several leaks in her pressure hull, the submarine surfaced and her crewmen abandoned ship. She was then scuttled and 46 out of 48 men were rescued by the Italian ships. ''Saracen''s wreck was discovere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Mersey
The River Mersey () is in North West England. Its name derives from Old English and means "boundary river", possibly referring to its having been a border between the ancient kingdoms of Mercia and Northumbria. For centuries it has formed part of the boundary between the Historic counties of England, historic counties of Lancashire and Cheshire. The Mersey starts at the confluence of the River Tame, Greater Manchester, River Tame and River Goyt in Stockport. It flows westwards through south Manchester, then into the Manchester Ship Canal at Irlam, becoming a part of the canal and maintaining its water levels. After it exits the canal, flowing towards Warrington where it widens. It then narrows as it passes between Runcorn and Widnes. From Runcorn the river widens into a large estuary, which is across at its widest point near Ellesmere Port. The course of the river then turns northwards as the estuary narrows between Liverpool and Birkenhead on the Wirral Peninsula to the west ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Scuttled
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel in t ...

Pressure Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Sardinia
Sardinia ( ; it, Sardegna, label=Italian, Corsican and Tabarchino ; sc, Sardigna , sdc, Sardhigna; french: Sardaigne; sdn, Saldigna; ca, Sardenya, label=Algherese and Catalan) is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica. It is one of the five Italian regions with some degree of domestic autonomy being granted by a special statute. Its official name, Autonomous Region of Sardinia, is bilingual in Italian and Sardinian: / . It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and Algherese Catalan are referred to by both the regional and national law as two of Italy's twelve officially recognized linguistic minorities, albeit gravely endangered, while the regional law provides ...

Corsica
Corsica ( , Upper , Southern ; it, Corsica; ; french: Corse ; lij, Còrsega; sc, Còssiga) is an island in the Mediterranean Sea and one of the 18 regions of France. It is the fourth-largest island in the Mediterranean and lies southeast of the French mainland, west of the Italian Peninsula and immediately north of the Italian island of Sardinia, which is the land mass nearest to it. A single chain of mountains makes up two-thirds of the island. , it had a population of 349,465. The island is a territorial collectivity of France. The regional capital is Ajaccio. Although the region is divided into two administrative departments, Haute-Corse and Corse-du-Sud, their respective regional and departmental territorial collectivities were merged on 1 January 2018 to form the single territorial collectivity of Corsica. As such, Corsica enjoys a greater degree of autonomy than other French regional collectivities; for example, the Corsican Assembly is permitted to exercise limit ...

French North Africa
French North Africa (french: Afrique du Nord française, sometimes abbreviated to ANF) is the term often applied to the territories controlled by France in the North African Maghreb during the colonial era, namely Algeria, Morocco and Tunisia. In contrast to French West Africa and French Equatorial Africa which existed as federations of French colonies and administrative entities in their own right, French North Africa was never more than a term of convenience to refer to the three separately governed territories under different forms of colonial regime. In the 19th century, the decline of the Ottoman Empire, which had loosely controlled the area since the 16th century, left the region vulnerable to other forces. In 1830, French troops captured Algiers and from 1848 until independence in 1962, France treated Algeria as an integral part of France, the ''Métropole'' or metropolitan France. In subsequent decades, a substantial European settler population emerged in Algeria known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
