The Virginia-class attack submarines (SSN) are the first U.S. submarines to be designed for battlespace dominance across a broad spectrum of regional and littoral missions. They complement the Seawolf class's capabilities for open-ocean, blue water missions, and are slated to replace the aging fleet of Los Angeles class attack submarines, some of which have already been decommissioned.
The Virginias incorporate several innovative design features. Perhaps the most radical change occurred in the sensor suite: Virginias have no periscopes. Rather, two extensible "photonics masts" are installed outside the pressure hull, each of which contain several high-resolution, color cameras with enhanced infrared and low-level light image enhancement features, an infrared laser range finder, and an integrated Electronic Support Measures (ESM) array and associated signal processing for unparalleled situational awareness. Signals from the masts' sensors are transmitted through fiber optic data lines to the control center.
To reduce costs, the Virginia-class make extensive use of 'off-the-shelf' components (especially in the onboard computer system and data network), which also shortens development timeframes. The Virginias have a unit cost roughly half that of a Seawolf.
A preliminary Pentagon budget draft circulated in January 2005 indicated that the Virginia-class submarine program may be deeply cut due to the growing Federal budget deficit.
