An automatic depth regulation system uses changes in water pressure to automatically control the depth of an underwater vehicle. The system uses a piston chamber having a piston that is movably disposed within the chamber and mechanically linked to the vehicle's fins. The bottom of the piston is subjected to pressure from the ambient environment through which the vehicle travels. The chamber contains a compressible medium at a preselected pressure above the piston. A spring is also above the piston in the chamber. Changes in ambient pressure on the bottom of the piston causes the piston to move within the chamber, thereby rotating the fins to adjust the depth of the vehicle to the desired, preselected, depth. The desired depth is determined by the pressure and spring force exerted on the top of the piston in opposition to the ambient pressure.
