Defense budgets.

Some of the constraints imposed on fighter jets is life support and G-force limitations for the pilot. Removing the pilot and allowing an on-board computer handle things in the moment (e.g. dogfights) gives an unmanned jet the upper hand.

It's obviously a step toward completely automated war machines, but that's the justification for the "unmanned fighter jet"

CCAs or collaborative combat aircraft are the new hotness in military aviation. Basically smaller unmanned fighter jets that work alongside a traditional manned fighter. The idea is that you can have maybe 4 or 5 fighter jets worth of capability but only one of them has a human pilot on board. So the manned fighter can hang back and tell a farther forward one to fire a missile. Is it a wunderwaffen? Is it a boondoggle? Idk man
