Abstract: Vehicle for aeronautic operation and submersed operation includes members secured to rotors and a body, the members having adjustable features arranged and disposed to position the rotors to rotate in a first plane during the aeronautic operation and a second plane during the submersed operation, a fluid enclosure operably connected through the body to the rotor, the fluid enclosure having a submersion mechanism arranged and disposed for the vehicle to adjustably ascend and descend during the submersed operation of the vehicle, and a control system and power system for operably controlling the rotor, the adjustable feature, and/or the fluid enclosure. The rotor is configured to move the vehicle during the aeronautic operation and the submersed operation. A process includes operating the vehicle in the aeronautic operation and the submersed operation.
