Torpedoes
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ...

Spar Torpedo
A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden hulls. A fuse could then be used to detonate it. Invention Robert Fulton had written about submarine (i.e., subsurface) marine torpedoes in 1810, and experiments were conducted using spar torpedoes that year. Boats carrying spar torpedoes were used during the War of 1812. E. C. Singer, a private engineer who worked on secret projects for the benefit of the Confederate States of America, constructed a spar torpedo during the American Civil War. His torpedo was detonated by means of a trigger mechanism adapted from a rifle lock (see flintlock mechanism for a similar device). The spring-loaded trigger was detonated by means of a long cord attached to the attacking vessel. The attacking vessel rammed its ...

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 ...

Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Frogmen
A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name ''The Fearless Frogman'' of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role. In the U.S. military and intelligence community, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Robert Fulton
Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the (also known as ''Clermont''). In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of , in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers. In 1800, Fulton had been commissioned by Napoleon Bonaparte, leader of France, to attempt to design a submarine; he produced , the first practical submarine in history. Fulton is also credited with inventing some of the world's earliest naval torpedoes for use by the Royal Navy.Best, Nicholas (2005). ''Trafalgar: The Untold Story of the Greatest Sea Battle in History''. London: Phoenix. . Fulton became interested in steam engines and the idea of steamboats in 1777 when he was around age 12 and visited state delegate William Henry o ...

Hasan Al-Rammah
Hasan al-Rammah (, died 1295) was a Syrian Arab chemist and engineer during the Mamluk Sultanate who studied gunpowders and explosives, and sketched prototype instruments of warfare, including the first torpedo. Al-Rammah called his early torpedo "an egg which moves itself and burns." It was made of two sheet-pans of metal fastened together and filled with naphtha, metal filings, and potassium nitrate Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrat .... It was intended to move across the surface of the water, propelled by a large rocket and kept on course by a small rudder. Al-Rammah devised several new types of gunpowder and a new type of fuse and two types of lighters.

Warship
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations. In wartime, the distinction between warships and merchant ships is often blurred. In war, merchant ships are often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service and not unusual for more than half a fleet to be composed of merchant ships. Until the threat of piracy subsided in the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cornelius Drebbel
Cornelis Jacobszoon Drebbel ( ) (1572 – 7 November 1633) was a Dutch engineer and inventor. He was the builder of the first operational submarine in 1620 and an innovator who contributed to the development of measurement and control systems, optics and chemistry. Biography Cornelis Drebbel was born in Alkmaar, Holland in an Anabaptist family in 1572. After some years at the Latin school in Alkmaar, around 1587, he attended the Academy in Haarlem, also located in North-Holland. Teachers at the Academy were Hendrik Goltzius, engraver, painter, alchemist and humanist, Karel van Mander, painter, writer, humanist and Cornelis Corneliszoon of Haarlem. Drebbel became a skilled engraver on copperplate and also took an interest in alchemy. In 1595 he married Sophia Jansdochter Goltzius, younger sister of Hendrick, and settled at Alkmaar. They had at least six children, of whom four survived. Drebbel worked initially as a painter, engraver and cartographer. But he was in constant need of ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Siege Of La Rochelle
The siege of La Rochelle (, or sometimes ) was a result of a war between the French royal forces of Louis XIII of France and the Huguenots of La Rochelle in 1627–28. The siege marked the height of the struggle between the Catholics and the Protestants in France, and ended with a complete victory for King Louis XIII and the Catholics. Background The 1598 Edict of Nantes that ended the French Wars of Religion granted Protestants, commonly known as Huguenots, a large degree of autonomy and self-rule. La Rochelle was the centre of Huguenot seapower, and a key point of resistance against the Catholic royal government. The assassination of Henry IV of France in 1610 led to the appointment of Marie de' Medici as regent for her nine-year-old son, Louis XIII. Her removal in 1617 caused a series of revolts by powerful regional nobles, both Catholic and Protestant, while religious tensions were heightened by the outbreak of the 1618 to 1648 Thirty Years War. In 1621, Louis re-estab ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
