Why the U.S Built Only 3 of the Deadliest Submarines Ever, Like The F-22 of Submarines

[Music] [Music] the extreme quietness of the Seawolf class gave the Navy the idea of modifying the last submarine USS Jimmy Carter to support clandestine operations an extra 100 feet was added to the hull a section known as the multi mission platform MMP the MMP gives carter the ability to send and recover remotely operated vehicles unmanned underwater vehicles and seals and diving teams while submerged it includes berthing for up to 50 seals or other attached personnel Carter also features one ciliary maneuvering devices for and aft for precise maneuvering in situations such as undersea cable tapping and other acts of espionage the Sea Wolf class submarines were envisioned as the best submarines ever built designed to succeed the los angeles-class attacked submarines and maintain America's edge of the underwater domain the class suffered from cost overruns in the collapse of the Soviet Union while still some of the best submarines ever built they were built at reduced numbers in many respects they are the f-22 of submarines widely considered in the world's best but costs made wide their wide usage a major challenge in the late 1980s the US Navy was faced with a crisis in 1980 the Soviet Union had received information from the Walker family spiring that the Navy could track its submarines through excessive propeller noise as a result the Soviet Union went looking for advanced Western machinery to make better propellers in 1981 the Japanese company Toshiba sold propeller milling machinery now a relatively common nine axis CNC milling machines to the Soviet Union via the Norwegian Kongsberg corporation by the mid-1980s the Soviet Union's new machinery began to make itself felt the new Acula class submarines had a steep drop in broadband acoustic noise profiles one government source told the Los Angeles Times the submarine started to get silent only after the Toshiba stuff went in on of running silent the Acula class could dive tunics of up to 2,000 feet while the US Navy's frontline submarines the los angeles-class could dive to only 650 feet to combat the threat of the Acula class the US Navy responded with the Sea Wolf class of nuclear attack submarines the Sea Wolf submarines were designed with high 100 steel alloy house 2 inches thick the better to withstand the pressures of deep diving high 100 steel is roughly 20% stronger than the high 80 used in the los angeles-class as a result the submarines are capable of diving to depths of up to 2,000 feet in crush depth estimates run from two thousand four hundred to three thousand feet at 353 feet si will subs were designed to be slightly shorter than their predecessors by just seven feet but with the 20% wider beam making them 40 feet wide this width made them substantially heavier than the subs before them topping the scales of 12,000 158 tons submerged the sea wolf submarines are each powered by one Westinghouse s6w nuclear reactor driving two steam turbines to a total of 52,000 shaft horsepower the class was the first class of American submarine to utilize pump jet propulsors / propellers a feature that is carried over to the newest Virginia class as a result a c loop is capable of 18 knots from the surface a maximum speed of 35 knots underwater in a silent - running speed of about 20 knots the Sea Wolf class is equipped with the bqq 5 D sonar system which features a 24 foot diameter bow-mounted spherical active and passive array as well as wide aperture passive flank arrays the submarines are being refitted with te b-29 a thin line towed array sonar systems rounding out sonar systems as the bqs 24 heard detection of close-range objects such as mines the ship's original combat data system was the Lockheed Martin vs y2 which uses a network of 70 motorola 68030 processors the same processor that drove early Macintosh computers and is now being replaced with the in by Guan weapons control system the submarines were designed to be true hunters and as a result of eight torpedo tubes double the number of earlier submarines it is stores fur up a combination of up to 50 mark 48 heavyweight torpedos sub Horton anti-ship missiles and Tomahawk missiles alternatively it can substitute some of this ordnance for mines [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] you [Music]
