A submarine device having a hull which is substantially symmetrical about a horizontal plane of symmetry and vertical longitudinal and transverse planes of symmetry. An integrated lift, propulsion and steering system is provided for the submarine device and comprises four conventional cycloidal propeller mechanisms in an arrangement in which two are mounted at the front of the hull and two at the rear, the two at the front being rotatable about a common transverse horizontal axis disposed below the horizontal plane of symmetry whereas the two at the rear are rotatable about a common transverse axis disposed above the horizontal plane of symmetry of the hull. Four auxiliary screws, rotatable about horizontal axes, can be arranged in pairs on the horizontal and vertical planes of symmetry respectively, the auxiliary screws having reversible blades and being capable of turning to produce vertical thrust.
