Abstract: A submersible marine vehicle, operable both upon and beneath water, includes a fluid-tight hull elongated along a longitudinal axis corresponding to an intended direction of travel of the vehicle, the hull having integral gripping elements and velocity controls proximal to each of the gripping elements, the hull further including internally energy storage elements for power control and transfer within an air space in the hull, the air space also defining a buoyancy characteristic of the vehicle, the hull defining a total longitudinal dimension co-linear to the longitudinal axis of the hull. The vehicle also includes a single circumferentially integral propeller shroud depending integrally downwardly from a lower surface of the hull along an axis transverse to the axis of the hull.
