The sky is too big, the distances are too large, and a fighter jet is moving too fast. What are these drones supposed to do, hope the jet flies close enough that the drone can act as a proximity mine? Plus, the kind of small drone you’re describing can’t operate at the altitude of a fighter jet. As the air thins out you need a lot of speed to keep sufficient oxygen flowing into the jets, and non-jet aircraft can’t operate. So unless the drones are going to be blimps, a drone that can climb to fighter jet altitude is going to be pretty big and look a lot like a fighter jet.
