Agreed. But there's going to be "happy medium" drones that can be delivered by a long-range mothership. Price is no object when you can take out a carrier.
That's just silly. For attacks against surface targets, the bombers or strike aircraft (possibly unmanned) are going to continue carrying large, fast cruise missiles just like they have been since the 1960's. There is zero reason to use quadcopter type drones for this mission.
