Abstract

An autonomous marine vehicle is disclosed, the vehicle comprising a rigid hull having an interior and a periphery, a deck joining the rigid hull at the periphery; and a rigid mast pivotally attached to the deck, the mast housing a plurality of sensors capable of effecting communication to and from said vehicle. In preferred embodiments, the vehicle further comprises various sensors and mission-specific hardware. Sensors include mast-mounted audio/video devices, radar, GPS and RF antennas, and other positioning and collision avoidance devices. Mission-specific hardware include refueling probes, fire protection systems, towing assemblies, flame thrower assemblies, liquid spray assemblies, and work pup assemblies.
