About the Virginia Class Submarines
Stealth, Endurance, and
Agility Under the Sea
Designed by Electric Boat, the Virginia-class is being built jointly under a
teaming arrangement between Electric Boat and Northrop Grumman Newport News in
Virginia.
In 1998, the U.S. Navy awarded a $4.2 billion contract for the construction of
the first four ships of the class. Virginia is the first of these. Displacing
approximately 7,800 tons with a length of 370 feet, Virginia is longer but
lighter than the previous Seawolf-class of submarines.
The 132-member crew can launch Tomahawk land-attack missiles from 12 vertical
launch system tubes and Mark 48 advanced capability torpedoes from four 21-inch
torpedo tubes.
Virginia will be able to attack targets ashore with highly accurate Tomahawk
cruise missiles and conduct covert long-term surveillance of land areas,
littoral waters or other sea forces. Other missions Virginia will conduct
include anti-submarine and anti-ship warfare, special forces delivery and
support, and mine delivery and minefield mapping. With enhanced communications
connectivity, Virginia also will provide important battle group and joint task
force support, with full integration into carrier battle group operations.
The Virginia-class of attack submaries surpasses the performance of any
current projected threat submarine, ensuring U.S. undersea dominance well into
the next century.
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
around the world. They were designed as a cheaper alternative to the Cold War
era Seawolf-class attack submarines, and are slated to replace aging Los Angeles
class subs, seventeen of which have already been decommissioned.
Innovations
The Virginias incorporate several innovations. Instead of
periscopes, the subs have a pair of extendable "photonics masts" outside the
pressure hull. Each contains several high-resolution cameras with
light-intensification and infrared sensors, an infrared laser rangefinder, and
an integrated Electronic Support Measures (ESM) array. Signals from the masts'
sensors are transmitted through fiber optic data lines through signal processors
to the control center. The subs also make use of pump-jet propulsors for quieter
operations.

On December 22, 2008, the Navy awarded a new $14B contract to the GDEB/NGC team
for eight more VA-class subs, the first of which will be NORTH DAKOTA. Beginning
in 2011, the Navy will double the current production rate by building two subs
per year. The new contract calls for construction times of 60 months and costs
to be held at $2B each (in 2005 dollars).
On 21 June 2008, the Navy christened the New Hampshire (SSN-778), the first of
the Block II boats. The submarine was delivered 8 months ahead of schedule and
$54 million underbudget.[8] The Block II boats are built in four sections,
compared to the ten sections of Block I boats. This enables a cost savings of
$300 million per boat, reducing the cost to $2 billion per boat and the
construction of two boats per year. Beginning in 2010, new vessels of the class
will include a software system that can monitor and reduce EM signatures when
needed.
