The Virginia class (or SSN-774 class) is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The submarines are designed for a broad spectrum of open-ocean and littoral missions. They were conceived as a less expensive alternative to the Seawolf class attack submarines, designed during the Cold War era, and they are planned to replace the older of the Los Angeles-class submarines, twenty of which have already been decommissioned (from a total of 62 built). The class was developed under the codename "Centurion", renamed to NSSN (New SSN) later on with design work (possibly) starting as early as 1993.
