Seawolf Class Fast Attack Submarine

Seawolf class fast attack submarines were designed to operate autonomously against the world's most capable submarine and surface threats. They are exceptionally quiet, fast, well-armed, and equipped with advanced sensors. Though lacking Vertical Launch Systems, the Seawolf class has eight torpedo tubes and can hold up to 50 weapons in its torpedo room. In addition to their capabilities in countering enemy submarines and surface shipping, Seawolf submarines are also suited for battlespace-preparation roles. Incorporation of sophisticated electronics produces enhanced indications and warning, surveillance, and communications capabilities.
