The Seawolf class attack submarine (SSN) was the intended successor to the Los Angeles class, ordered at the end of the Cold War  in 1989. 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 Virginia class.

Compared to previous Los Angeles class submarines, Seawolf  subs are larger, faster, and significantly quieter; they also carry more weapons and have twice as many torpedo tubes, for a total of 8. As a result of their advanced design, however, Seawolf subs were much more expensive. They were intended to combat the then-threat of large numbers of advanced Soviet ballistic missile submarines such as the Typhoon class and attack submarines such as the Akula class in a deep ocean environment.

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 52,000 hp (39 MW) to a low-noise screw.
