The Virginia Class attack
submarine is the U.S. Navy’s newest undersea warfare platform and
incorporates the latest in stealth, intelligence gathering and weapons
systems technology. Attack submarines are designed to seek and destroy
enemy submarines and surface ships; project power ashore with Tomahawk
cruise missiles and Special Operation Forces; carry out Intelligence,
Surveillance, and Reconnaissance (ISR) missions; support battle group
operations; and engage in mine warfare.


The Virginia class wa not the first new design to come into service
after the Cold War. The Seawolf class was originally intended to
succeed the Los Angeles class, but production was canceled after only
three submarines were produced. This restriction occurred due to
budgeting restraints at the end of the Cold War, and the final
submarine was manufactured in 1995. At a cost of $3 billion per unit,
the Seawolf class was the most expensive SSN submarine. The Virginia
class was put into production in full swing due to being smaller and
carrying more manageable costs than the Seawolf.


The Navy is now building the next-generation attack submarine, the
Virginia (SSN 774) class. The Virginia class has several innovations
that significantly enhance its warfighting capabilities with an emphasis
on littoral operations. Virginia class SSNs have a fly-by-wire ship
control system that provides improved shallow-water ship handling. The
class has special features to support special operation forces including
a reconfigurable torpedo room which can accommodate a large number of
special operation forces and all their equipment for prolonged
deployments and future off-board payloads.


The class also has a large lock-in/lock-out chamber for divers. In
Virginia-class SSNs, traditional periscopes have been supplanted by two
photonics masts that host visible and infrared digital cameras atop
telescoping arms. With the removal of the barrel periscopes, the ship’s
control room has been moved down one deck and away from the hull’s
curvature, affording it more room and an improved layout that provides
the commanding officer with enhanced situational awareness.
Additionally, through the extensive use of modular construction, open
architecture, and commercial off-the-shelf components, the Virginia
class is designed to remain state of the practice for its entire
operational life through the rapid introduction of new systems and
payloads.


As part of the Virginia-class’ third, or Block III, contract, the
Navy redesigned approximately 20 percent of the ship to reduce their
acquisition costs. Most of the changes are found in the bow where the
traditional, air-backed sonar sphere has been replaced with a
water-backed Large Aperture Bow (LAB) array which reduces acquisition
and life-cycle costs while providing enhanced passive detection
capabilities. The new bow also replaces the 12 individual Vertical
Launch System (VLS) tubes with two 87-inch Virginia Payload Tubes
(VPTs), each capable of launching six Tomahawk cruise missiles. The VPTs
simplify construction, reduce acquisition costs, and provide for more
payload flexibility than the smaller VLS tubes due to their added
volume.
