A subsea system for exploiting an oceanic current shear includes a first vehicle positionable in a first oceanic current and tethered to a second vehicle positionable in a second oceanic current. The first and second oceanic currents have a velocity differential. A drag or lift device integral or attached to the first vehicle exerts a force through the tether on the second vehicle and its associated drag or lift device, thus providing a net propulsive force. Hydrofoils or control devices attached to the vehicles provide hydrodynamic lift, drag, and/or depth control that allow the direction of the force to be controlled for propulsion in a desired direction. The relative currents and/or change in separation of the vehicles can be used for energy harvesting. Turbines and generators coupled to the vehicles harvest energy for long term subsea endurance. A sensor aperture comprises a plurality of sensors coupled to components of the subsea system.
