Here’s a new concept I’ve been playing with. Sectors of space in Star Wars have enormous numbers of systems to patrol. We see probe droids being used to blanket recon planets in TESB, but I think there’s a gap for persistent ISTAR craft; small ships could do it but it doesn’t seem like a very efficient use of trained manpower. Droids are perfect for this – long endurance, low logistical requirements, fully expendable if they find something dangerous. Jump into a system, passive scan, line up on another system, do it again until fuel gets low.
So here’s a droid probe ship concept, roughly shuttle/transport sized, mounting individual sensor elements from a star destroyer sensor dome, wrapped around a reactor and sensor processing core.
