Torpedo Development Unit
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 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 large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir Thomas Hardy, 1st Baronet
Vice-Admiral Sir Thomas Masterman Hardy, 1st Baronet, GCB (5 April 1769 – 20 September 1839) was a British Royal Navy officer. He took part in the Battle of Cape St. Vincent in February 1797, the Battle of the Nile in August 1798 and the Battle of Copenhagen in April 1801 during the French Revolutionary Wars. He served as flag captain to Admiral Lord Nelson, and commanded HMS ''Victory'' at the Battle of Trafalgar in October 1805 during the Napoleonic Wars. Nelson was shot as he paced the decks with Hardy, and as he lay dying, Nelson's famous remark of "Kiss me, Hardy" was directed at him. Hardy went on to become First Naval Lord in November 1830 and in that capacity refused to become a Member of Parliament and encouraged the introduction of steam warships. Early life Born the second son of Joseph Hardy and Nanny Hardy (née Masterman) at Kingston Russell House in Long Bredy (or according to some sources in Winterborne St Martin), Hardy joined the navy with his entry abo ...

New London, Connecticut
New London is a seaport city and a port of entry on the northeast coast of the United States, located at the mouth of the Thames River in New London County, Connecticut. It was one of the world's three busiest whaling ports for several decades beginning in the early 19th century, along with Nantucket and New Bedford, Massachusetts. The wealth that whaling brought into the city furnished the capital to fund much of the city's present architecture. The city subsequently became home to other shipping and manufacturing industries, but it has gradually lost most of its industrial heart. New London is home to the United States Coast Guard Academy, Connecticut College, Mitchell College, and The Williams School. The Coast Guard Station New London and New London Harbor is home port to the Coast Guard Cutter ''Coho'' and the Coast Guard's tall ship ''Eagle''. The city had a population of 27,367 at the 2020 census. The Norwich–New London metropolitan area includes 21 towns and 274,055 ...

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] |
American Revolutionary War
The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was a major war of the American Revolution. Widely considered as the war that secured the independence of the United States, fighting began on April 19, 1775, followed by the Lee Resolution on July 2, 1776, and the Declaration of Independence on July 4, 1776. The American Patriots were supported by the Kingdom of France and, to a lesser extent, the Dutch Republic and the Spanish Empire, in a conflict taking place in North America, the Caribbean, and the Atlantic Ocean. Established by royal charter in the 17th and 18th centuries, the American colonies were largely autonomous in domestic affairs and commercially prosperous, trading with Britain and its Caribbean colonies, as well as other European powers via their Caribbean entrepôts. After British victory over the French in the Seven Years' War in 1763, tensions between the motherland and he ... [...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] |
King James I
James VI and I (James Charles Stuart; 19 June 1566 – 27 March 1625) was King of Scotland as James VI from 24 July 1567 and King of England and Ireland as James I from the union of the Scottish and English crowns on 24 March 1603 until his death in 1625. The kingdoms of Scotland and England were individual sovereign states, with their own parliaments, judiciaries, and laws, though both were ruled by James in personal union. James was the son of Mary, Queen of Scots, and a great-great-grandson of Henry VII, King of England and Lord of Ireland, and thus a potential successor to all three thrones. He succeeded to the Scottish throne at the age of thirteen months, after his mother was compelled to abdicate in his favour. Four different regents governed during his minority, which ended officially in 1578, though he did not gain full control of his government until 1583. In 1603, he succeeded Elizabeth I, the last Tudor monarch of England and Ireland, who died childless. He ... [...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 ...

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 ...
