Auk-class Minesweeper
The ''Auk'' class were a class of minesweepers serving with the United States Navy and the Royal Navy during World War II. In total, there were 93 ''Auk''s built. Design and development Prior to the United States entering World War II, they had produced two ships of the for testing and evaluation. From these two examples it was decided that the use of diesel-electric engines to power the ship and the minesweeping equipment, rather than separate geared diesel engines to propel the ship and diesel generators to energize the minesweeping equipment, would work better. The Royal Navy placed an order for 32 of these minesweepers from the United States, ''BAM-1'' - ''BAM-32''. Because of the additional equipment, the displacement was raised from on the ''Raven''s, to on what would come to be known as the ''Auk'' class in the USN, and the ''Catherine'' class in the RN. The ''Auk'' class displaced 890 long tons, with a length of , a beam of , and a draft of . They had a maximum speed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper
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, when they were deployed by the British. The Crimean War minesweepers were rowboats trailing Grappling hook, 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, 3rd Baronet, Sir Arthur Wilson noted the real threat of the time was a blockade aided by mines and not an invasion. The function of the ...

Cleveland Diesel Engine Division
The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines, tugboats, destroyer escorts, s and other marine applications. Emergency generator sets were also built around the Cleveland Diesel and were installed in many US warships. The division was created in 1938 from the GM-owned Winton Engine Corporation and was folded into the GM Electro-Motive Division in 1962. The engines continue in use today on older tugs. History Cleveland Diesel traces it roots to the Winton Gas Engine and Manufacturing Company, which was formed by the early Cleveland automobile manufacturer Alexander Winton in November 1912. Winton soon expanded into production of heavy spark-ignition and diesel engines, introducing the first American diesel in 1913. Renamed the Winton ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 somet ...

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Busch-Sulzer
The Busch-Sulzer Bros. Diesel Engine Company was founded by Adolphus Busch of the Anheuser-Busch brewing company in 1911 as a joint venture with Sulzer Brothers of Switzerland. The company manufactured diesel engines until 1946. In 1897, Adolphus Busch acquired rights to build diesel engines in the United States, with Rudolph Diesel as a consultant. The first companies resulting from this were the Diesel Motor Company (1898–1902) of New York City and the American Diesel Engine Company (1902–1911), which relocated to St. Louis, Missouri in 1908 and was succeeded by Busch-Sulzer. Although Busch acquired the rights to build Sulzer designs with the formation of Busch-Sulzer, the American joint venture preferred its own designs.
