That would be new. Dog fighting drones. Now that would be interesting to watch.
I suppose the only reason we haven't seen such is that the US has not faced significant aerial opposition since before the advent of the modern drone. Of course, surface to air missiles, such as the SM-2MR, are just specialized drones.
Except for their limited range, autonomy once launched, can't be recovered, vastly less human interface etc, they are really drone like as the military defines it drone capability
