The Seawolf Class is a series of three American nuclear attack submarines, developed and built by General Dynamics Electric Boat. The first of the class, the USS Seawolf SSN-21, entered service with the US Navy in 1997; the other two submarines of this class are the USS Connecticut SSN-22, commissioned in 1998, and the USS Jimmy Carter SSN-23, which entered service in 2005, partially replacing the Los Angeles Class submarines.
The submarines of the Seawolf Class are powered by one S6W nuclear reactor, producing 45,000 horsepower. They sail at the maximum speed of 39+ knots (submerged) and they have an unlimited range, but they have to stop for food and ammunition supplies. Built with HY-100 steel, the hardest steel yet known, the Seawolf submarine can go down underwater to the maximum depth of 2,100 ft + (620 m+). However the strongest feature is stealth as the hull is covered by several layers of special materials which make them practically undetectable. The Seawolfs are armed with 50 UGM-109 Tomahawk cruise missiles and 16 Harpoon torpedoes.
