Task Force Whirlwind

Task Force Whirlwind was an Imperial Navy unit under Grand Admiral Thrawn. It consisted of three Imperial-class Star Destroyers (the Gorgon, Verox, and Hydrus) as well as several Dreadnaught-class heavy cruisers.

In 0 BBY, during the Galactic Civil War, they fought the rogue Admiral Harkov in the Triton system of the Mid Rim, where he took control of the vital E-40 starfighter production facility.
