SV-A99 was an SV-class supervisor droid that was constructed on the moon Uffel during the waning years of the Galactic Republic. In circa 31 BBY, the rogue droid LN-73 sabotaged a droid production line on Uffel, and SV-A99 was among a group of SV-class droids that were dispatched to oversee repairs to the damaged assembly line.
