Doomhammer was the callsign of an assault dropship in service to the Terran Dominion. Several years after the Brood War, Doomhammer was involved in ferrying a Dominion Marine Corps squad to Vespene Refinery BF 1138 on Mar Sara to reinforce the ground team engaged against the zerg. However, it was destroyed by a flight of mutalisks en route, along with fellow dropship Lightbringer.
