Attack submarines, designed to seek and destroy enemy subs and surface ships,
are the stealthy members of the battle group. They boast cutting edge
technology—the concept of technical prowess over numerical superiority is
still the driving force in U.S. submarine development. Other uses range from
intelligence collection and the delivery of Special Forces, to anti-ship and
strike warfare. The Navy began construction of Seawolf class submarines in
1989. Seawolf is exceptionally quiet, fast and well armed.
Far more common today are the Los Angeles-Class submarines. For more
information about these nuclear-powered subs, take a virtual tour of the
USS Springfield.
