1. With in-air refueling, a greatly increased time in the air vs manned aircraft. Not unique to unmanned aircrafts. On the other hand, pilots need to go to the restroom, get hungry, and tired. 2. Ability to outmaneuver any manned aircraft by exceeding the human g limit. Only useful if human pilot have low latency access to aircraft, or if AI is good enough to fight. Otherwise, you're good as owned. 3. Greatly lowered cost in both manufacture and pilot training (or lack of). Useful, when nobody is trying to shoot down your drone. 4. When fully realized, AI that is superior to human pilots -- increasing overall combat effectiveness and reducing error. In 30 years, maybe.
