HMS Rorqual (S02)
HMS ''Rorqual'' (S02) was a ''Porpoise''-class submarine launched in 1956. She was built by the Vickers shipyard in Barrow-in-Furness, Cumbria, England. The boat was named for both the rorqual, a family of whale, and the earlier Second World War-era submarine of the same name. Design and construction The ''Porpoise''-class was the first class of operational submarines built for the Royal Navy after the end of the Second World War, and were designed to take advantage of experience gained by studying German Type XXI U-boats and British wartime experiments with the submarine , which was modified by streamlining and fitting a bigger battery. The ''Porpoise''-class submarines were long overall and between perpendiculars, with a beam of and a draught of . Displacement was standard and full load surfaced and submerged. Propulsion machinery consisted of two Admiralty Standard Range diesel generators rated at a total of , which could charge the submarine's batteries or direc ...

Vickers-Armstrongs
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. It featured among Britain's most prominent armaments firms.

Draft (ship)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if depl ...

USS Endurance (AM 435)
USS ''Endurance'' (AM-435/MSO-435) was an ''Agile''-class minesweeper in service with the United States Navy from 1954 to 1972. She was scrapped in 1974. History The second ship to be named ''Endurance'' by the Navy, ''AM-435'' was launched 8 August 1952 by J. M. Martinac Shipbuilding Corp., Tacoma, Washington; sponsored by Miss Gerry A.

In July 1955 she made a good will cruise to Acapulco, Mexico, returning to local duty on exercises, drills, and operations with ships of other types. ''Endurance'' made her first cruise to the Far East between August 1957 and February 1958, during which she exercised with ships of the Japanese Maritime Self Defense Force and the navy of the Republic of China. Her second tour of duty in the Far East, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, when they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was a blockade aided by mines and not an invasion. The function of the fishing fleet's trawlers with their trawl ge ...

Singapore
Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet.

In its early history, Singapore was a maritime emporium known as '' Temasek''; subsequently, it was part of a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under the direct control of Britain as part of the Straits Settlements. During World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mozambique
Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the south and southwest. The sovereign state is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and dialect. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of the Portuguese Empire, Portuguese, who began a gradual process of colonisation and settlement in 1505.

Inhambane
Inhambane (also known as Terra de Boa Gente (''Land of Good People'')) is a city located in southern Mozambique, lying on Inhambane Bay, 470 km northeast of Maputo. It is the capital of the Inhambane Province and, according to the 2017 census, has a population of 79,724, growing from 54,157 in the 1997 census. The settlement owes its existence to a deep inlet into which the small Mutamba River flows. Two protective sandy headlands protect the harbour and form a sandbank. The sister town of Maxixe is located across the bay from Inhambane. History Inhambane is one of the oldest settlements on Mozambique's eastern coast. Dhows traded here as early as the 11th century. Muslim and Persian traders were the first outsiders to reach the area by sea and traded pearls and ambergris. They also traded at Chibuene in the north. The area became well known for its local cotton spinning and production by the Tonga tribe. Sometime before the Portuguese reached the area, the Karanga ...

Faslane
His Majesty's Naval Base, Clyde (HMNB Clyde; also HMS ''Neptune''), primarily sited at Faslane on the Gare Loch, is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Devonport and HMNB Portsmouth). It is the navy's headquarters in Scotland and is best known as the home of Britain's nuclear weapons, in the form of nuclear submarines armed with Trident missiles. History Faslane was first constructed and used as a base in the Second World War. During the 1960s, the British Government began negotiating the Polaris Sales Agreement with the United States regarding the purchase of a Polaris missile system to fire British-built nuclear weapons from five specially constructed submarines. In the end, only four were constructed; , , and . These four submarines were permanently based at Faslane. Faslane itself was chosen to host these vessels at the height of the Cold War because of its geographic position, which forms a bastion on the relati ...

Mediterranean
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. 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. 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.
