This is an Autonomous Underwater Vehicle that uses a combination of propolsion systems. A variable buoyancy system for silent deep ocean crossing and a diesel electric system for shallow water. Four dive planes with an electric motor mounted on the tip makes the sub highly manuverable. A retractedable 15 foot mast combining radar, GPS, 30x day/night video camera, radio antenna, and snorkel. A sonar pod is mounted on the end of the rudder mount.
