Jet powered drones... why not just call them affordable cruise missiles at this point?
Electronics like raspberry pi's and optical-recognition software and cheap GPS could probably be hooked up. Slap on cheap infrared or radiation-sensors, you just found a way to make missiles cheap and affordable to mass-produce.
Maybe use starlink stuff could be interesting for a kill-chain.
No more multi-million dollar cruise missiles, is starting to look like a reality.
