      The  Sea  Shadow is 160 feet long, 70 feet wide, displaces
660  tons and has a draft of 14 feet. It has a maximum speed
of  approximately 38 knots and is powered  by  a  twin-screw
diesel electric drive.Armed with a modified Arleigh Burke VLS
launcher and Aegis system. The Sea Shadow is what all modern FAC's
should be: Fast, Quiet, Manueverable and WELL ARMED.
      The Sea Shadow should be used in areas of low intensity 
conflict, with other FAC's or in the protection of a battle
group in any High intensity conflict area.
      The sloped sides of the vehicle are an extension of the
angled  struts, which were driven by signature, hydrodynamic
and structural considerations.
      The test program for the Sea Shadow was initiated in the
mid-1980s and is a  combined effort of the Advanced Research 
Project  Agency,the Navy and Lockheed.
      Signature  control technology from the Sea Shadow  has
already  been  incorporated into the  DDG-51  Arleigh  Burke
class  destroyers. In addition, Small Waterplane  Area  Twin
Hull  technology has been incorporated into the TAGOS-19,  a
twin  hull ocean surveillance ship that serves as a platform
to tow the Surveillance Towed Array Sensor.
