I don't know if this has been posted before but drones are not new. In Louisiana last week looked at ww2 navy destroyer, the "Orlech"?? that was refitted with a helicopter drone in 1962 with two rotors, a little jet turbine, a drone operator to take off and land it on the deck before handing over to CIC who directed it, with a load of small depth charges or torpedoes to its target. I have some photos, which I don't know how to post, but will happily email to anyone who wants to post them. It is a long while from 1962 to 2017 but not much has changed.
