Norad-series battlecruisers

The Norad-series of battlecruisers were powerful battlecruisers designed by the Terran Confederacy and Terran Dominion. The two known examples of the line, the Norad II and the Norad III, were both commanded by General Edmund Duke.

Norad II
The Norad II had enhanced weapons systems compared to most other battlecruisers. It was also defensively superior to Behemoth-class battlecruisers.

These weapons systems could not save it from a Zerg assault over Antiga Prime, however. It crashed on Antiga Prime, but Duke and his crew were rescued by the Sons of Korhal.

After Duke joined the Sons of Korhal, it was repaired and joined in Duke's attack on the Confederate forces in orbit of Tarsonis.

By StarCraft: Brood War Episode V it was replaced by the Norad III.

Norad III
The Norad III was (apparently) superior to the Norad II. With General Duke on board, it was destroyed by Infested Kerrigan's forces on Korhal shortly after the Zerg launched a sneak attack on the Terran Dominion.
