Drones?

[Vanguard]

The fins will be functional.

Would a spaceborne drone have fins?

Maybe for planetary surface bombardment I suppose.

Just a thought.

While not necessary for maneuvering, the artwork shows them as present... and since mankind has added stabilizing fins to it's missiles for hundreds of years... that's a lot of ingrained belief to overcome.
I vote, Yes. Fins would be present on the drones.

I recall seeing SVC's description of his artwork stating that the fins are antenna to receive tracking data from the controlling ship.
