The United States Army is looking into using, Autonomous Vertical Takeoff and Landing (VTOL) Unmanned Aircraft Systems (UAS) to deliver medical supplies in situations where it might not be reasonable to send a rescue team. These unmanned aircraft are also to be used to pick up injured soldiers.
The Army is not asking to develop new technology or new aircraft, but to repurpose the existing aircraft they use now.
The A160 Hummingbird is one of the unmanned aircraft being used that would be preferred. As well as the K-MAX and the Black Hawk is a suggestion for remote-control modification.
