Abstract: A submersion system for a rotorcraft is described and includes a control module for controlling a depth to which the rotorcraft is submerged in a body of water; a compressed air chamber associated with the control module; and at least one flotation pod including a sealable opening on a top surface thereof and an opening on a bottom surface thereof. The control module selectively causes water to be taken into the at least one flotation pod to cause the submersion system to submerge in the body of water and selectively causes water to be evacuated from the at least one flotation pod to cause the submersion system to float in the body of water.
