Submarine Mine
A controlled mine was a circuit fired weapon used in coastal defenses with ancestry going back to 1805 when Robert Fulton termed his underwater explosive device a torpedo: Robert Fulton invented the word torpedo to describe his underwater explosive device and successfully destroyed a ship in 1805. In the 1840s Samuel Colt began experimenting with underwater mines fired by electric current and in 1842, he blew up an old schooner in the Potomac River from a shore station five miles away. History "Torpedoes" were in use during the American Civil War when such devices were made famous with the order given by David Farragut at Mobile Bay. After that war similar mines were being contemplated or put into use by other nations. In 1869 the United States Army Corps of Engineers was directed by Secretary of War William Belknap to assume responsibility for torpedoes for coastal defense. That responsibility continued through the formation of the U.S. Torpedo Service as part of the United Sta ... [...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, New York, 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 then 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).

Militia (United Kingdom)
The British Militia was the principal military reserve force of the United Kingdom of Great Britain and Ireland. Militia units were repeatedly raised in Great Britain during the Victorian era, Victorian and Edwardian eras for internal security duties and to defend against external invasions. The British Militia was transformed into the Special Reserve under the Territorial and Reserve Forces Act 1907, which integrated all militia formations into the British Army. 19th century A separate voluntary Local Militia was created in 1808 before being disbanded in 1816. By 1813 the British Army was experiencing a shortage of manpower to maintain their battalions at full strength. Some consideration was given to recruiting foreign nationals; however, on 4 November 1813 a bill was introduced to Parliament to allow Militia volunteers to serve in Europe. In the event only three battalions were raised, and these were sent to serve under Henry Bayly (British Army officer, born 1769), Henry Bay ...

Anti-ship Weapons
Beginning in the mid-2010s, significant discourse emerged within fan spaces such as Tumblr and Archive of Our Own (AO3) regarding the ethical implications of portraying taboo and abusive sexual content within shipping fanfiction. "Shipping"—the depiction of a romantic or sexual relationship between fictional characters—has long been a staple within fanfiction. The lack of censorship emerging from spaces such as AO3 allowed for the portrayal of disturbing or taboo dynamics within fan works, including incest, abuse, rape, and pedophilia. Within fandom, discourse is divided between "anti-ship" and "pro-ship" camps, focusing primarily on the extent to which fictional works depicting such content affect real-world behavior and attitudes. Anti-shippers, referred to as "antis," take the view that fictional portrayals normalize harmful dynamics and behaviors and pose a particular threat to children. Fanfiction depicting underage characters in sexual contexts is characterized as ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive 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.

Hashima-class Cable Layer
The were the only class of purpose-built cable layers of the Imperial Japanese Navy (IJN), serving during World War II. Four vessels were built in 1939–41 under the Maru 4 Programme. Apart from laying communications cables, these ships were also designed as mine planters, for the installation of controlled mines in coastal fortifications. Ships in class Project number J21.

Linnet-class Minelayer
The ''Linnet ''class were a class of three small coastal minelayers commissioned into the Royal Navy just before the Second World War. Description The ''Linnet'' class were the largest of a dozen specialized vessels known as "Indicator Loop Mine Layers" built for the Royal Navy immediately before and during the Second World War. These vessels were designed to lay controlled mines, used in coastal defences, as well as anti-submarine indicator loops. Similar vessels known as mine planters were operated by the US Army during the same era. Ships of the class had a displacement of 498 tons standard and a length of between perpendiculars. They were equipped with a single 20 mm gun and two machine guns. They had two triple expansion engine A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be trans ...

Anti-submarine Indicator Loop
An anti-submarine indicator loop was a submerged cable laid on the sea bed and used to detect the passage of enemy submarines. History In the early years of World War I submarines were fearful, one-sided weapons because they were invisible. In July 1915 Arthur Balfour replaced Winston Churchill as First Lord of the Admiralty. Balfour appreciated the importance of science, so he established a Board of Invention and Research (BIR), composed of a three-man central committee supported by an eminent consulting panel. The remits of Section II of the panel, the members of which included physicists Ernest Rutherford and William Henry Bragg, included anti-submarine measures. The panel concluded that the most promising approach was to listen for submarines, so they sought to improve hydrophones. Bragg soon moved to the hydrophone research centre HMS Tarlair at Aberdour on the Firth of Forth (which later relocated to Harwich in Essex). Independently from the BIR, in August 1915, a s ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Mine Planter Service (U
The U.S. Army Mine Planter Service (AMPS) was an outgrowth of civilian crewed Army mine planter ships dating back to 1904. It was established on July 22, 1918 by War Department Bulletin 43 and placed the Mine Planter Service under the U.S. Army Coast Artillery Corps. Its purview was to install and maintain the underwater minefields that were part of the principal armament of U.S. coastal fortifications, including those at the approaches to the Panama Canal and the defenses of Manila Bay in the Philippines. Origin Prior to the formal establishment of the Mine Planter Service, the Coast Artillery Corps had operated ships designated as Mine Planters, as well as an assortment of smaller vessels to establish and maintain the coastal defense mine fields. The ships, originating with vessels drafted into the work, were replaced by special construction in 1904 and 1909. Another block began with one ship, ''Gen. William M. Graham'' of 1917, and a group of nine constructed in 1919 to brin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Planter (ship)
Mine planter and the earlier "torpedo planter" was a term used for mine warfare ships into the early days of World War I. In later terminology, particularly in the United States, a mine planter was a ship specifically designed to install controlled mines or contact mines in coastal fortifications. This type of ship diverged in both function and design from a ship operating as a naval minelayer. Though the vessel may be seagoing it is not designed to lay large numbers of mines in open sea. A mine planter was designed to place controlled minefields in exact locations so that they might be fired individually or as a group from shore when observers noted a target to be at or near a designated mine's position. The terms and types of specialized ship existed from the 1860s where "torpedoes" were made famous in the American Civil War until the demise of large, fixed coastal fortifications brought on by the changes of World War II.
