The design was for a C-130-size V/STOL transport for the US Army's Future Transport Rotorcraft program and would have 50% commonality with ...
Bell created the V-247 to meet emerging U.S. military needs for a runway-independent Group 4 or 5 UAV to provide persistent support to ground forces while requiring less space to store and transport; Group 4 UAVs weigh more than 1,320 lb (600 kg) and fly below 18,000 ft (5,500 m), while Group 5 UAVs weigh the same but fly above 18,000 ft, such as the MQ-9 Reaper, RQ-4 Global Hawk, and MQ-4C ...
