A large “hoverbike” like quadcopter is being developed for the military, the JTARV(Joint Tactical Aerial Resupply Vehicle) intended for autonomous delivery of supplies to troops. The current vehicle can carry up to 300 pounds over short distances. The goal is to increase the range to 125 miles and to increase the payload to 800 pounds.
The prototype was flown recently at the Aberdeen Proving Ground in Maryland.
If the development is successful, and the goals are met, then these could serve many uses in the front lines.
