Domm was a group of four Class-A cargo containers. The containers were located at a staging area for TIE/D Defenders and each contained parts for the starfighters as well as crew quarters. The Galactic Empire dispatched a pair of Missile Boats to destroy all TIE Defenders in the area. The destruction of Domm group was considered a secondary objective. The operation was later used as a training exercise for Missile Boat pilots.
