"We already use robotics in the military. You see unmanned aerial vehicles as a form of a robot. We are experimenting today with surface and subsurface vessels in the Navy," Milley said during a commissioning ceremony at Princeton University.
"I would submit to you that within 10 or 15 years, you're going to have a partially pilotless Air Force, that most of your airplanes are likely to be robots of some kind with the man-machine interface between them."
The US will be equipped in the future with robotic unmanned ground vehicles that will nullify casualties during convoy movements as was the case in Afghanistan and Iraq, Milley said.
Artificial intelligence, robotics, precision fires and enhanced monitoring ability will provide for the next fundamental change in the conduct of war in a highly dynamic world.
Earlier in May, US President Joe Biden announced his intention for current US Air Force Chief of Staff Charles Brown to serve as the next chairman of the Joint Chiefs of Staff instead of Milley, who will retire in four months.
