Sea Wolf Class Submarines
The Seawolf design was intended to combat the threat of large numbers of advanced Soviet Navy ballistic missile submarines such as the Typhoon class and attack submarines such as the Akula class 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 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. Each boat is powered by a single S6W nuclear reactor, delivering 45,000 hp (34 MW) to a low-noise pump-jet.
Seawolf-class SSN Profile
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.
