Virginia Class

The Virginia class (or SSN-774 class) of attack submarines are the first U.S. subs to be designed for a broad spectrum of open-ocean and littoral missions. They are slated to replace aging Los Angeles-class attack submarines, some of which have already been decommissioned.

The Virginias were intended as a cheaper alternative to the $2 billion Seawolf subs, whose production run was stopped after just three vessels. To reduce costs, the Virginias use many "off-the-shelf" components, especially in their computers and data networks. But they actually cost about $2.6 billion each, thanks in part to an industrial arrangement designed to keep Electric Boat and Newport News Shipbuilding in the sub-building business, according to the Congressional Research Service. The firms run the only U.S. shipyards that build nuclear vessels.
