Why do the "smaller systems" only get a brief mention at the end of your comment? There are relatively few uses for an unmanned but full size aircraft. The advantage to using a drone is that it can often do the same task previously done by a large, manned aircraft but at a fraction of the cost and complexity due to its reduced size Imagine being able to send out ten drones to scour a mountain for lost climbers, and on the same day that they got lost (rather than waiting until tomorrow to make sure they really are lost and it really is worth spending thousands launching a single helicopter)
