SS Alcantara (1913)
RMS ''Alcantara'' was an ocean liner which entered service just weeks before the start of World War I, was converted to an armed merchant cruiser in 1915, and was sunk in combat with the German armed merchant cruiser in the Action of 29 February 1916. Ocean liner Harland and Wolff in Govan built ''Alcantara'' for the Royal Mail Steam Packet Company. She was one of the later members of RMSP's "A-series" of liners, which had begun with RMS ''Aragon'' launched in 1905. In common with all of the last four "A-series" ships, ''Alcantara'' had triple screws Propelles. A pair of four-cylinder triple-expansion steam engines drove the port and starboard pair. Exhaust steam from their low-pressure cylinders powered a Parsons low-pressure steam turbine that drove the middle screw propeller . ''Alcantara'' was launched on 30 October 1913 and made her maiden voyage in June 1914 on RMSP's route from Southampton to Rio de Janeiro, Montevideo and Buenos Aires. ''Alcantara'' was regi ...

United Kingdom Of Great Britain And Ireland
The United Kingdom of Great Britain and Ireland was a sovereign state in the British Isles that existed between 1801 and 1922, when it included all of Ireland. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927. The United Kingdom, having financed the European coalition that defeated France during the Napoleonic Wars, developed a large Royal Navy that enabled the British Empire to become the foremost world power for the next century. For nearly a century from the final defeat of Napoleon following the Battle of Waterloo to the outbreak of World War I, Britain was almost continuously at peace with Great Powers. The most notable exception was the Crimean War with the Russian Empire, in which actual hostilities were relatively limited. How ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...

Board Of Trade
The Board of Trade is a British government body concerned with commerce and industry, currently within the Department for International Trade. Its full title is The Lords of the Committee of the Privy Council appointed for the consideration of all matters relating to Trade and Foreign Plantations, but is commonly known as the Board of Trade, and formerly known as the Lords of Trade and Plantations or Lords of Trade, and it has been a committee of the Privy Council of the United Kingdom. The board has gone through several evolutions, beginning with extensive involvement in colonial matters in the 17th century, to powerful regulatory functions in the Victorian Era and early 20th century. It was virtually dormant in the last third of 20th century. In 2017, it was revitalised as an advisory board headed by the International Trade Secretary who has nominally held the title of President of the Board of Trade, and who at present is the only privy counsellor of the board, the other m ...

Code Letters
Code letters or ship's call sign (or callsign) Mtide Taurus - IMO 7626853"> SHIPSPOTTING.COM >> Mtide Taurus - IMO 7626853/ref> were a method of identifying ships before the introduction of modern navigation aids and today also. Later, with the introduction of radio, code letters were also used as radio call signs. History In 1857, the United Kingdom sponsored the ''Commercial Code of Signals for the Use of All Nations at Sea'', which introduced four letter flag signal codes to identify individual ships. The first vessel to be reported in ''Lloyd's List'' by her letters was the ''Mallard'' (LDPN), off Deal, Kent whilst on a voyage from London to Calcutta, India. The Commercial Code of Signals, c. 1900, was modified to become the International Code of Signals. By the 1860s, individual ships were being allocated code letters in the United States and Europe. From 1874, code letters were recorded in Lloyd's Register as part of each individual vessel's entry in the register. Generally ...

Port And Starboard
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMT Aragon
HMT ''Aragon'', originally RMS ''Aragon'', was a transatlantic Royal Mail Ship that served as a troop ship in the First World War. She was built in Belfast, Ireland in 1905 and was the first of the Royal Mail Steam Packet Company's fleet of "A-liners" that worked regular routes between Southampton and South American ports including Buenos Aires. In 1913 ''Aragon'' became Britain's first defensively armed merchant ship ("DAMS") of modern times. In the First World War she served as a troop ship, taking part in the Gallipoli Campaign in 1915. In 1917, a German submarine sank her in the Mediterranean, killing 610 of the personnel aboard. Building Owen Philipps became chairman of RMSP in 1903 and quickly addressed the company's need for larger ships on its South America route. RMSP ordered ''Aragon'' from Harland and Wolff, who built her on slip number 7 of its South Yard in Belfast. The Countess Fitzwilliam launched her on 23 February 1905. Harland and Wolff completed the ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action Of 29 February 1916
The action of 29 February 1916 was a naval engagement fought during the First World War between the United Kingdom and the German Empire. , a German commerce raider, broke out into the North Sea and Admiral Sir John Jellicoe dispatched Royal Navy warships to intercept the raider. Four British vessels intercepted the commerce raider ''Greif''. The armed merchant cruiser and ''Greif'' fought a brief engagement before British reinforcements arrived when both were severely damaged, both being sunk. Background In April 1915 the Admiralty requisitioned ''Alcantara'' and the other "A-series" ships , and as armed merchant cruisers. ''Alcantara'' was armed with six guns, anti-aircraft guns and depth charges. On 17 April at Liverpool she was commissioned into the 10th Cruiser Squadron as HMS ''Alcantara''. ''Arlanza'' and ''Andes'' were also commissioned into the 10th Cruiser Squadron, which joined the Northern Patrol, part of the Blockade of Germany. The Squadron patrolled ab ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Liner
An ocean liner is a passenger ship primarily used as a form of transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes (such as for pleasure cruises or as hospital ships). Cargo vessels running to a schedule are sometimes called ''liners''. The category does not include ferry, ferries or other vessels engaged in short-sea trading, nor dedicated cruise ships where the voyage itself, and not transportation, is the primary purpose of the trip. Nor does it include tramp steamers, even those equipped to handle limited numbers of passengers. Some shipping companies refer to themselves as "lines" and their container ships, which often operate over set routes according to established schedules, as "liners". Ocean liners are usually strongly built with a high Freeboard (nautical), freeboard to withstand rough seas and adverse conditions encountered in the open ocean. Additionally, they are often designed with thicker H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Atlantis (1913)
Space Shuttle ''Atlantis'' (Orbiter Vehicle designation: OV‑104) is a Space Shuttle orbiter vehicle which belongs to NASA, the spaceflight and space exploration agency of the United States. ''Atlantis'' was manufactured by the Rockwell International company in Southern California and was delivered to the Kennedy Space Center in Eastern Florida in April 1985. ''Atlantis'' is also the fourth operational and the second-to-last Space Shuttle built. Its maiden flight was STS-51-J made from October 3 to 7, 1985. ''Atlantis'' embarked on its 33rd and final mission, also the final mission of a space shuttle, STS-135, on July 8, 2011. STS-134 by ''Endeavour'' was expected to be the final flight before STS-135 was authorized in October 2010. STS-135 took advantage of the processing for the STS-335 Launch on Need mission that would have been necessary if STS-134's crew became stranded in orbit. ''Atlantis'' landed for the final time at the Kennedy Space Center on July 21, 2011. By th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
