Auk Class
The ''Auk'' class were a class of minesweepers serving with the United States Navy and the Royal Navy during the Second World War. 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 ... [...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, where 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 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 ...
