The walker had an open cockpit where the driver and operator—or gunner—were seated. The gunner was positioned towards the rear of the walker, behind a protective plate.
Designed as a load-lifting exoskeleton, maintenance Uggernaughts featured plasma torches and magnetic projectors for lifting extremely heavy materials. Armed walkers were fitted with a cannon and a projectile launcher to the walker's right and left respectively. The Uggernaught could move quite fast, and its cannons were also capable of rapid fire.[source?]
Uggernaughts were employed throughout Bespin on construction platforms. Imperial-loyal Ugnaughts employed several Uggernaughts in a confrontation with former Sith apprentice Galen Marek and Jedi Master Rahm Kota during the Great Jedi Purge.[source?]
