when do you think air to air combat will be conducted by drone aircraft instead of manned aircraft, I think the yanks will be the first to have this capability if they don't already have it (early stages) , the direction drone technology is going I could see the first true air to air combat by drone aircraft by 2025 for me this will be the first stage towards drone aircraft being the dominant superiority fighter (sixth generation) cost will be a key factor
The problem for any drone is whose hand is on the trigger, human or the machine.
A human shoots a civilian by mistake, its the individual.
But when a machine shoots a civilian by mistake, its all of them. So you have to ground the fleet until it is fixed. Finding and correcting the bug is probably relatively easy, but the testing process to find and fix any new problems the change creates before you can install it in the fleet is long and complex -- weeks, possibly months, maybe even years if enough other problems show up. Just look at the software problems with the F-35 or Microsoft Windows.
If a human still makes the decision you need secure, jam proof, communications. That’s a big gamble, especially if the other side can kill your communications satellites. You are also running up against bandwidth problems that limit how many drones can be in a given area, depending on how much data you have to pass to the human decision maker.
My guess, when drone fighters are deployed you are going to 2 or 3 drones working with a 2 seat fighter serving as a local control aircraft.
