The all-electric DeepFlight Dragon is designed specifically for easy use from yacht or shore to explore the twilight zone down to 400 ft (120 m). At 3,968 lb (1,800 kg) and under 5 ft (1.5 m) in height, the Dragon is less than half the weight of competing submarines and readily fits into existing yacht garages or deck areas. Like all DeepFlight personal submarines, the Dragon is positively buoyant, meaning the craft automatically floats to the surface. And the Dragon is the first DeepFlight craft to use vertical thrust, thus enabling a hover capability.

The two-person Dragon is the only personal submarine which has enough power to rely solely on vertical thrust to dive, eliminating the complexity of the ballast and drop weight systems that all competing submersibles use to get heavy and sink to depth. This newest DeepFlight craft also uniquely offers the DeepFlight Dive Manager, a proprietary technology that monitors and manages critical functions, therefore eliminating the need for a professional pilot in a third seat.
