SSN-594"金鯧魚級"攻擊核潛艇
SSN-594"長尾鯊級"攻擊核潛艇
註:此級艦艇英文命名共兩組、但中譯與漢翻的版本卻很多,標題仍以英文第二組官方翻譯為主。
以下是該級艦的各類翻譯:
"大參魚"、"金鯧魚"、"許可證"
原文:
In 1956 Admiral Arleigh Burke, then CNO, requested that the Committee on Undersea Warfare of the National Academy of Sciences to study the effect of advanced technology on submarine warfare. The result of this study, dubbed "Project Nobska" was an increased emphasis on deeper-diving, ultraquiet designs utilizing long-range sonar. The Permit class was based on Project Nobska旧 recommendations. Hull streamlining, reduction in sail dimensions by approximately 50%, quieting of the propulsion plant and an increase in test depth all led to a dramatic advance in submarine operational capabilities and stealth.
The SSN-594 Permit class was the world's first modern, quiet, deep-diving fast attack submarines, integrating such advanced features as a hydrodynamically shaped hull, a large bow mounted sonar array, advanced sound-silencing features, and an integrated control/attack center with the proven S5W reactor plant. These submarines were a major advance over previous submarine designs, and established the pattern of all successive American attack submarine classes, in several extremely important respects:
They were the first submarines to have hulls constructed of High Yield-80 (HY-80) steel alloy, which allowed operations at substantially greater depths than previous submarines.
They were the first submarines to have raft mountings for turbines, motors and other equipment, resulting in substantially quieter operations.
They were the first submarines to have a large bow-mounted sonar requiring the installation of torpedo tubes amidships, aft of the forward crew compartment.
Although they were larger than the previous SSN 585 Skipjack class, and used the same nuclear power plant, their hull design did not compromise their underwater speed. Designed for prolonged periods submerged, they were limited only by the amount of food that she can carry, and were capable of sustained operation at high speed.
These submarines were originally designated the THRESHER class, but the USS Thresher (SSN 593) was lost 200 miles off the coast of New England on 10 April 1963. According to investigators, a seawater pipe in the aft engine spaces broke, spraying water into the engine room and shorting one of the main electrical bus boards. The sub lost electrical power and couldn't operate the reactor. Darkness, a sea mist, and sheer terror inhibited the crew from manually actuating the valves. The aft part of the sub filled up with water and tilted down. With no power to get back on line, the sub drifted down to crush depth and imploded. A ghastly death for an entire crew, and one the US Navy vowed never to allow happen again. |
