The Dragon is small autonomous underwater vehicle (AUV) that can tow a payload whose drag is many times larger than that of the AUV. The Dragon presents a number of design challenges. For example, the highly-loaded propulsion system must provide many times more thrust than needed for the AUV alone, but without cavitation or excessive roll-moment. Likewise, the control system requires unconventional control affectors for maneuving due to the large restoring moment imparted by the towed payload.
