In StarCraft, General Edmund Duke commands the Terran battlecruiser Norad II.
The Norad II appears during the original StarCraft campaign after it is damaged and forced down on the planet Antiga Prime. Jim Raynor helps defend the wrecked battlecruiser from the Zerg, after which Duke and his forces become connected to the developing story of the Terran Confederacy and the Dominion.
Duke later serves Arcturus Mengsk and becomes one of the most prominent military commanders in the Terran Dominion. His ship is therefore an important link between the early Terran campaign and the political rise of Mengsk.
The name is easy to confuse with the Hyperion, which is Jim Raynor’s flagship in StarCraft II, or with the Norad III, a later battlecruiser associated with Duke. The original StarCraft vessel commanded by Duke is specifically the Norad II.
