The class was the intended successor to the Los Angeles class, and design work began in 1983. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion per unit ($3.5 billion for USS Jimmy Carter), making it the most expensive SSN submarine and second most expensive submarine ever, after the French SSBN Triomphant class.

Seawolf combat system
The combat data system is a Lockheed Martin BSY-2 with a network of 70 68030 Motorola processors. It was replaced by the Raytheon AN/BYG-1 combat system. Weapons control is managed by the Raytheon mk2 fire control system.

Seawolf missiles
Similarly to the improved Los Angeles Class, the Seawolf does not have any external weapons. The submarine is armed with both the land-attack and anti-ship version of the Tomahawk missile from Raytheon. The land-attack Tomahawk has a range of 2,500km.

Design
The Seawolf design was intended to combat the threat of advanced Soviet 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.
