 A shaft-driven lift fan would exhaust through the nosewheel door for vertical landings, while the nose sensor array would pivot forward to expose the intakes for the lift fan.The UCAV would have a retractable refueling probe, communications antennas mounted on the aircraft's spine, and lights for navigation and refueling operations.Moveable wingtips and control surfaces along the sawtooth rear edge of the UCAV would eliminate the need for vertical stabilizers.
