What makes you think UAVs are restricted to props for propulsion?
Pain

Can you give a cite for a ramjet model? Also, could you please cite a
role for a ramjet powered UAV (other than a harpoon/tomahawk - I suppose
they could be considered UAVs).


Ramjet - D21 :-)

The original question was about non-prop power, however.
Most of the large UAV's are jets. Like GlobalHawk.

The small and medium sized ones are prop driven.
