It was designed to automatically target a mineral rich asteroid and mine it. Mineral Exploiters were used in the Hoth asteroid field to produce materials for the Darksaber weapon.

Delta and Gamma replaced them. The programming on the later two was changed to prevent one Exploiter from targeting another.
