SS Clement
SS ''Clement'' was a British turbine steamship operated by the Alfred Booth and Company from 1934 to 1939 until she was intercepted and sunk by the German pocket battleship '' Admiral Graf Spee'' off the east coast of Brazil becoming the first victim of ''Graf Spee's'' commerce raiding sortie Construction A significant consequence of the Great Depression was a global slump in merchant shipping. Booth Line responded by renewing its fleet, selling 11 older ships and replacing them with a smaller number of new ones. Part of this strategy resulted in the Line ordering two cargo ships from the Birkenhead yards of Cammell Laird in 1934. ''Clement'' was launched on 11 October 1934 and completed that December. Her sister ship was launched on 7 December 1934 and completed in March 1935. The ''Clement'' was the 1,000th vessel launched by Cammel Laird's at Birkenhead. ''Clement's'' main engine was a three-cylinder triple-expansion steam engine which drove a single propeller. Exhaust ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Merchant Navy (United Kingdom)
The Merchant Navy is the maritime register of the United Kingdom and comprises the seagoing commercial interests of UK-registered ships and their crews. Merchant Navy vessels fly the Red Ensign and are regulated by the Maritime and Coastguard Agency (MCA). King George V bestowed the title of "Merchant Navy" on the British merchant shipping fleets following their service in the First World War; a number of other nations have since adopted the title. Previously it had been known as the Mercantile Marine or Merchant Service, although the term "Merchant Navy" was already informally used from the 19th century. History The Merchant Navy has been in existence for a significant period in English and British history, owing its growth to trade and imperial expansion. It can be dated back to the 17th century, when an attempt was made to register all seafarers as a source of labour for the Royal Navy in times of conflict. That registration of merchant seafarers failed, and it was not su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sortie
A sortie (from the French word meaning ''exit'' or from Latin root ''surgere'' meaning to "rise up") is a deployment or dispatch of one military unit, be it an aircraft, ship, or troops, from a strongpoint. The term originated in siege warfare. In aviation In military aviation, a sortie is a combat mission of an individual aircraft, starting when the aircraft takes off. For example, one mission involving six aircraft would tally six sorties. The sortie rate is the number of sorties that a given unit can support in a given time. In siege warfare In siege warfare, the word ''sortie'' refers specifically to a sudden issuing of troops against the enemy from a defensive position—that is, an attack launched against the besiegers by the defenders. If the sortie is through a sally port, the verb ''to sally'' may be used interchangeably with ''to sortie''. Purposes of sorties include harassment of enemy troops, destruction of siege weaponry and engineering works, joining the relief ...

Commerce Raiding
Commerce raiding (french: guerre de course, "war of the chase"; german: Handelskrieg, "trade war") is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them. Privateering The first sort of commerce raiding was for nations to commission privateers. Early instances of this type of warfare were by the English and Dutch against the Spanish treasure fleets of the 16th century, which resulted in financial gain for both captain and crew upon capture of enemy vessels ("Prize (law), prizes"). 17th and 18th centuries Privateers formed a large part of the total military force at sea during the 17th and 18th centuries. In the First Anglo-Dutch War, English privateers attacked the trade on which the United Provinces of the Netherlands, United Provinces entirely depended, capturing over 1,000 Dutch merchant ships. During the subsequent Anglo-Spanish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
