Morphology

unmanned = manned (transparent) = un + man + ed

The negative prefix 'un-' added to 'manned' ('having a crew') yields the straightforward meaning 'not crewed'.

Etymology

Unmanned is made from un- 'not' and man 'person', so it means 'not with a person'. Today we use it for vehicles or devices, like drones or space probes, that work without anyone on board.
