Bell revealed their newest drone design this year at the 2018 Modern Day Marine Expo. The V-247 Vigilant is an unmanned tilt-rotor that has been pitched as an idea for the U.S Marine Corps’ MUX (Marine Air Ground Task Force Unmanned Aircraft System Expeditionary) program. The aircraft has technology similar to that of the V-22 Osprey and the V-280 Valor, reports The Drive.
