First integrated sonar suite, including both a low-frequency passive array, for long range detection, and a spherical array, for approach and attack (AN/BQQ Series Sonar). Only nuclear submarine specifically designed as an ASW (Anti-Submarine Warfare) weapon (i.e., a SSKN ).
Seawolf was the same basic "double hull" twin-screw submarine design as her predecessor USS Nautilus (SSN-571), but her propulsion system was more technologically advanced. The Submarine Intermediate Reactor (SIR) nuclear plant was designed by General Electric 's Knolls Atomic Power Laboratory and prototyped in West Milton, New York .
