Design of an unmanned autonomous vehicle capable of operating in air, on the surface, and underwater was explored to assess technical and technological issues required by such a vehicle. A goal of the vehicle was a footprint comparable to an 11m Rigid Hull Inflatable Boat RHIB to facilitate shipboard compatibility. Characteristics of the design are gross weight less than 8 tonne, wing span of 11m, length of 5m, and height of 2.4m. Airborne cruise speed is estimated to be over 100 knots. Maximum submergence depth is 50m. A major objective of the project was to explore the complex design issues associated with a vehicle that operates in the three fluid domains and document the design process used.
