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.
