Tyrant

The Tyrant was an Imperial II-class Star Destroyer in the Imperial Navy. Under the command of Captain Lennox, it served as part of Darth Vader's personal fleet, Death Squadron. In 3 ABY, along with the rest of the fleet, it took part in the Battle of Hoth, where the Empire assaulted the Rebel Alliance's secret base on the ice planet Hoth.

The rebels had installed a powerful deflector shield to protect their base, so the five Imperial Star Destroyers of Death Squadron, including the Tyrant, blockaded the planet to stop Alliance forces from escaping the Imperial ground assault. As such, the Tyrant tried to intercept the first rebel transport attempting to flee Hoth; however, the Star Destroyer was disabled by the rebels' v-150 ion cannon and left to drift into deep space while the rebel ship escaped.
