Arsenal De Cartagena
The Cartagena Naval Base, also known as Arsenal of Cartagena, is a military base and arsenal of the Spanish Navy located in the city of Cartagena. It is one of the oldest naval bases in Spain, having been created in the 18th century. Located in the southeast of the Iberian Peninsula, it is the main Spanish base in the Mediterranean Sea. History The port of Cartagena, first founded by the Carthaginians in the 2nd century BC, occupies a strategic location on the Mediterranean Sea. It remained a commercial port until the reign of Philip V, when it was redeveloped as a major naval base alongside the expansion of the Spanish Navy. Construction of the arsenal began in late 1731, and was completed in 1782, during the reign of Charles III. The final cost came to 112 million reales. The Cartagena naval base was a major industrial complex by the 18th century, with shipyards and workshops, carrying out carpentry, rigging and blacksmithing, as well as crafts and fine arts workshops to prod ...

Naval Base
A naval base, navy base, or military port is a military base, where warships and naval ships are docked when they have no mission at sea or need to restock. Ships may also undergo repairs. Some naval bases are temporary homes to aircraft that usually stay on ships but are undergoing maintenance while the ship is in port. In the United States, the United States Department of the Navy's General Order No. 135 issued in 1911 as a formal guide to naval terminology described a naval station as "any establishment for building, manufacturing, docking, repair, supply, or training under control of the Navy. It may also include several establishments". A naval base, by contrast, was "a point from which naval operations may be conducted". In most countries, naval bases are expressly named and identified as such. One peculiarity of the Royal Navy and certain other navies which closely follow British naval traditions is the concept of the stone frigate A stone frigate is a naval esta ...

Carpentry
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally 4 years—an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agosta-class Submarine
The ''Agosta''-class submarine is a class of diesel-electric fast-attack submarine developed and constructed by the French DCNS in the 1970s to succeed the submarines. The submarines have served in the French Navy as well as exported to the navies of Spain and Pakistan. It also used by Royal Malaysian Navy for the training purpose. They were replaced in French service by the nuclear attack submarines but are still in active service with the navies of Spain and Pakistan. The French Navy grouped this model of submarine in their most capable class as an ''océanique'', meaning "ocean-going." The ''Agosta'' class is named for its lead unit, , which in turn was named for the Battle of Augusta (french: Agosta) of 22 April 1676. Ships French Navy built by Arsenal de Cherbourg * ''Agosta'' (S 620) – completed 1977 – decommissioned 1997 * ''Bévéziers'' (S 621) – completed 1977 – decommissioned 1998 * ''La Praya'' (S 622) – completed 1978 – decommissioned 2000 * ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Dry Docks
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moats
A moat is a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building or town, historically to provide it with a preliminary line of defence. In some places moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental. They could also act as a sewer. Historical use Ancient Some of the earliest evidence of moats has been uncovered around ancient Egyptian castles. One example is at Buhen, a castle excavated in Nubia. Other evidence of ancient moats is found in the ruins of Babylon, and in reliefs from ancient Egypt, Assyria, and other cultures in the region. Evidence of early moats around settlements has been discovered in many archaeological sites throughout Southeast Asia, including No ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Isabella II Of Spain
Isabella II ( es, Isabel II; 10 October 1830 – 9 April 1904), was Queen of Spain from 29 September 1833 until 30 September 1868. Shortly before her birth, the King Ferdinand VII of Spain issued a Pragmatic Sanction to ensure the succession of his firstborn daughter, due to his lack of a son. She came to the throne a month before her third birthday, but her succession was disputed by her uncle the Infante Carlos (founder of the Carlist movement), whose refusal to recognize a female sovereign led to the Carlist Wars. Under the regency of her mother, Spain transitioned from an absolute monarchy to a constitutional monarchy, adopting the Royal Statute of 1834 and Constitution of 1837. Her effective reign was a period marked by palace intrigues, back-stairs and antechamber influences, barracks conspiracies, and military '' pronunciamientos''. She was deposed in the Glorious Revolution of 1868, and formally abdicated in 1870. Her son, Alfonso XII, became king in 1874. Bi ...

Galleys
A galley is a type of ship that is propelled mainly by oars. The galley is characterized by its long, slender hull, shallow draft, and low freeboard (clearance between sea and gunwale). Virtually all types of galleys had sails that could be used in favorable winds, but human effort was always the primary method of propulsion. This allowed galleys to navigate independently of winds and currents. The galley originated among the seafaring civilizations around the Mediterranean Sea in the late second millennium BC and remained in use in various forms until the early 19th century in warfare, trade, and piracy. Galleys were the warships used by the early Mediterranean naval powers, including the Greeks, Illyrians, Phoenicians, and Romans. They remained the dominant types of vessels used for war and piracy in the Mediterranean Sea until the last decades of the 16th century. As warships, galleys carried various types of weapons throughout their long existence, including rams, catapults, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hulk (medieval Ship Type)
A hulk (or "holk") was a type of medieval sea craft, a technological predecessor of the carrack and caravel. The hulk appears to have remained a relatively minor type of sailing ship apparently peculiar to the Low Countries of Europe where it was probably used primarily as a river or canal boat, with limited potential for coastal cruising. The only evidence of hulks is from legal documents and iconography. History The name hulk may come from the Greek word ''holkas'', meaning a towed boat, which would be consistent with the use of the hulk as a river barge. The word hulk also has a medieval meaning of "hollowed-out" or "husk-like" which is also apposite for the shape of the basic hulk. It is not clear when the hulk first appeared in medieval Europe. There is a lack of archaeological evidence because no wreck has been found. The only evidence of hulks comes from iconography of ships scholars believe to be hulks and medieval documentation of trade and regulations. It is commonly ...

Xebecs
A xebec ( or ), also spelled zebec, was a Mediterranean sailing ship that was used mostly for trading. Xebecs had a long overhanging bowsprit and aft-set mizzen mast. The term can also refer to a small, fast vessel of the sixteenth to nineteenth centuries, used almost exclusively in the Mediterranean Sea. Description Xebecs were ships similar to galleys primarily used by Barbary pirates, which have both lateen sails and oars for propulsion. Early xebecs had two masts while later ships had three. Xebecs featured a distinctive hull with pronounced overhanging bow and stern, and rarely displaced more than 200 tons, making them slightly smaller and with slightly fewer guns than frigates of the period. Use by Barbary corsairs These ships were easy to produce and were cheap, and thus nearly every corsair captain (''Raïs'') had at least one xebec in his fleet. They could be of varying sizes. Some ships had only three guns while others had up to forty. Most xebecs had around 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brigs
A brig is a type of sailing vessel defined by its rig: two masts which are both square rig, square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships. Brigs were prominent in the coasting coal trade of British waters. 4,395 voyages to London with coal were recorded in 1795. With an average of eight or nine trips per year for one vessel, that is a fleet of over 500 colliers trading to London alone. Other ports and coastal communities were also be served by colliers trading to Britain's coal ports. In the first half of the 19th century, the va ...
