Stormhawk was an Imperial I-class Star Destroyer of the Galactic Empire, according to Legends continuity.
Prior to the Battle of Endor, the Stormhawk was observed undergoing weapons systems evaluations at the Imperial Academy located on Carida. Following the Liberation of Coruscant which took place in 7 ABY, the Stormhawk received orders to proceed to the New Republic-controlled world of Saarn for a rapid offensive operation. During this military action, Stormhawk's technical teams established a covert listening post and determined that the New Republic's defenses on Saarn were weak, which led to the Stormhawk deploying numerous Stormtrooper units to seize the base.
The Stormhawk was integrated into Grand Admiral Thrawn's personal fleet during his campaign against the New Republic, approximately five years after the Battle of Endor (9 ABY). The Stormhawk participated in the Battle of Sluis Van, where it unsuccessfully attempted to capture undefended New Republic ships. Later, it served as a support vessel for the Chimaera during the attack on the Ukio system, where its mission was to deploy a pair of Carrack-class cruisers equipped with a working cloaking device, which were intended to be pivotal in the assault. The final recorded appearance of the Stormhawk was at the Battle of Bilbringi.
