Fundamental question here. Stealth - low signature. Drone - RF link back to a controller. Isn’t that a basic conflict?
It can be autonomous.
Yeah if it’s transmitting you can target that.
probably operates on automatic logic circuits eliminating the need for a direct link for much of its mission. This is a bomber, it just has to fly to a set of way points, drop its payload on a final GPS coordinate, and then return from whence it came via a second set of way points or the same way points. Not a lot of “thought processes” would be required. A fighter plane would have to do a lot more “thinking”.
The downfall of drones is the failure to maintain EMCON. Someone will eventually figure out how to ferret out the signal and get a location on the drone. Unless the software exists for the to identify the target in a dynamic environment, there will still be some signals activity going on. So the only way to implement stealth technology with EMCON is to have a manned aircraft.
Drones may still work for now dealing with low-tech opponents, or we think low tech - one will eventually develop a countermeasure.
Just remember that an F-117 Nighthawk was shot down over Serbia by an SA-3 Goa in 1999. Not exactly a state of the art missile at that time.
