Seawolf-class submarine
The ''Seawolf'' class is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the . Design work began in 1983.〔http://www.navy.mil/navydata/cno/n87/history/chrono.html〕 At one time, an intended fleet of 29 submarines was to be built over a ten-year period, later reduced to twelve submarines. The end of the Cold War and budget constraints led to the cancellation in 1995 of any further additions to the fleet, leaving the ''Seawolf'' class limited to just three boats. This, in turn, led to the design of the smaller . The ''Seawolf'' class cost about $3 billion ($3.5 billion for USS ''Jimmy Carter'') making it the most expensive SSN submarine and second most expensive submarine ever after the French SSBN .
== Design ==
The ''Seawolf'' design was intended to combat the threat of large numbers of advanced Soviet Navy ballistic missile submarines such as the and attack submarines such as the in a deep ocean environment. ''Seawolf'' class hulls are constructed from HY-100 steel, which is stronger than the HY-80 steel employed in previous classes, in order to withstand water pressure at greater depths.
Compared to previous ''Los Angeles''-class submarines, ''Seawolf'' submarines are larger, faster, and significantly quieter; they also carry more weapons and have twice as many torpedo tubes, for a total of 8. The boats are able to carry up to 50 UGM-109 Tomahawk cruise missiles for attacking land and sea surface targets. The boats also have extensive equipment to allow for littoral, or shallow water, operations. The class uses the more advanced ARCI Modified AN/BSY-2 combat system, which includes a new, larger spherical sonar array, a wide aperture array (WAA), and a new towed-array sonar.〔http://www.harpoondatabases.com/Encyclopedia/Entry2316.aspx〕 Each boat is powered by a single S6W nuclear reactor, delivering to a low-noise pump-jet.
As a result of their advanced design, however, ''Seawolf'' submarines were much more expensive. The projected cost for twelve submarines of this class was $33.6 billion, but after the Cold War ended, construction was stopped at three boats.〔(【引用サイトリンク】title=SSN-21 Seawolf Class )〕
