No, they can just shoot one down and hold the pilot.
You can make drones more resistant to jamming. You can make them smarter so that they won't need control signals so much.
We can send drones with a preset mission. If they jamb them then we have no way to recall the mission. Oops, too bad, boom.
The advantage of a drone is that it is expendable. And we’ve expended a lot of them in Iraq and Afghanistan.
But the remote link does much more than just fly the plane. The remote link also controls the onboard sensors and relays real-time data back. If the link is jammed, the drones already have a failsafe autopilot to fall back on, but there would be no intel.
