Kite-class Minesweeper
The ''Kite''-class minesweepers were a class of two ships operated by the United States Navy during World War II. Both ships were built as fishing trawlers in 1928 by the Bath Iron Works Corporation of Bath, Maine Bath is a city in Sagadahoc County, Maine, in the United States. The population was 8,766 at the 2020 census. It is the county seat of Sagadahoc County, which includes one city and 10 towns. The city is popular with tourists, many drawn by its ..., for F. J. O'Hara and Sons, Inc. of Boston, Massachusetts. The ships were acquired by the U.S. Navy in late 1940, and converted to minesweepers at Bethlehem Steel Co. of East Boston, Massachusetts, and commissioned in early 1941. Both were disposed of towards the end of the war. Ships * * References {{Kite class minesweeper * Mine warfare vessel classes World War II minesweepers of the United States ...

Bath Iron Works
Bath Iron Works (BIW) is a major United States shipyard located on the Kennebec River in Bath, Maine, founded in 1884 as Bath Iron Works, Limited. Since 1995, Bath Iron Works has been a subsidiary of General Dynamics. It is the fifth-largest defense contractor in the world as of 2008. BIW has built private, commercial, and military vessels, most of which have been ordered by the United States Navy. History Bath Iron Works was incorporated in 1884 by General Thomas W. Hyde, a native of Bath who served in the American Civil War. After the war, he bought a shop that made windlasses and other iron hardware for the wooden ships built in Bath's many shipyards. He expanded the business by improving its practices, entering new markets, and acquiring other local businesses. By 1882, Hyde Windlass was eyeing the new and growing business of iron shipbuilding, and it incorporated as Bath Iron Works in 1884. On February 28, 1890, BIW won its first contract for complete vessels: two iron gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bath, Maine
Bath is a city in Sagadahoc County, Maine, in the United States. The population was 8,766 at the 2020 census. It is the county seat of Sagadahoc County, which includes one city and 10 towns. The city is popular with tourists, many drawn by its 19th-century architecture. It is home to the Bath Iron Works and Heritage Days Festival, held annually on the Fourth of July weekend. It is commonly known as "The City of Ships" because of all the sailing ships that were built in the Bath shipyards. Bath is part of the metropolitan statistical area of Greater Portland. History Abenaki Indians called the area Sagadahoc, meaning "mouth of big river". It was a reference to the Kennebec River, which Samuel de Champlain explored in 1605. Popham Colony was established in 1607 downstream, together with Fort St George. The settlement failed due to harsh weather and lack of leadership, but the colonists built the New World's first oceangoing vessel constructed by English shipwrights, the ''Vi ...

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Fairbanks-Morse
Fairbanks, Morse and Company was an American manufacturing company in the late 19th and early 20th century. Originally a weighing scale manufacturer, it later diversified into pumps, engines, windmills, coffee grinders, radios, farm tractors, feed mills, locomotives, and industrial supplies until it was purchased by Penn Texas in 1958. There are three separate corporate entities that could be considered successors to the company, none of which is a complete and direct descendant of the original company.

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driveshaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3"/50 Caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships.

M1919 Browning Machine Gun
The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries. The M1919 was an air-cooled development of the standard US machine gun of World War I, the John M. Browning-designed water-cooled M1917. The emergence of general-purpose machine guns in the 1950s pushed the M1919 into secondary roles in many cases, especially after the arrival of the M60 in US Army service. The United States Navy also converted many to 7.62 mm NATO, and designated them Mk 21 Mod 0; they were commonly used on riverine craft in the 1960s and 1970s in Vietnam. Many NATO countries also converted their examples to 7.62 mm caliber, and these remained in service well into the 1990s, as well as up to the present day in some countries. Operation Loading The ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom.
