All UAVs or UAS will in the future become fully autonomous.

UAVs or UAS will in the future become fully autonomous and will be powered only by lithium-ion battery systems. Like advanced artifical intelligence these systems will be able to sense where they are, what they are doing, what they should be doing, where they should go to complete the pre-programmed task and how they can complete that task most efficiently and effectively and with a certain degree of luck return to base.  In the future the UAS rather than the UAV pilot will be the biggest decision-maker during a mission with the UAV pilot just monitoring what the vehicle is doing.
