Iron Duke was a Strike-class medium cruiser that was an escort ship for Task Force Whirlwind.

The task force was supposed to rendezvous with a convoy of Missile Boats that were used as bait to lure Demetrius Zaarin's forces into a trap. Zaarin sent the Maelstrom to destroy the task force, but they were repelled. However, they managed to stall the task force long enough to be hopelessly behind schedule.
