Avenger

The Avenger was an Imperial Star Destroyer in service with the Empire during the Galactic Civil War. It was commissioned as part of Vader's Death Squadron and participated in the attack on the Rebel Base on Hoth. It took only minor damage during the battle and later pursued the Millenium Falcon through an asteroid field, and despite the fact that it failed to catch the ship it later gained a reputation for being the fastest ship in Death Squadron, even faster than the Stalker.

The ships captain, Needa, was executed by Darth Vader for failing to capture the Millenium Falcon, but this mattered little to the rest of the crew as most of them were glad to have escaped the asteroid belt alive. The Avenger was later used as a communications vessel during the Battle of Endor, and it therefore survived and was used by the remnants of the Empire for many years afterwards.
