Aerodynamics aren't problem, dogfighting drones(called missiles) are a thing for 7 decades now.Actually Yankee states clearly in the podcast that there will be a CCA type drone specified for A2A/dogfight in China's 6gen system. So after the CAC/SAC 6gen program revealed I'm thinking, what would a dogfighting drone be?
The more interesting thing is how to setup situational awareness in dogfight(and priority/fof logic in group fight with deteriorating comm picture), while still preferably costing less than a manned aircraft.
Otherwise what's the purpose of it, go optionally manned for same money and be happy.
