The Mark VI Supremacy-class starfighter, alternatively referenced as the ISF interceptor or just the Mk. VI interceptor, represented a specific starfighter design employed by the revived Sith Empire throughout the timeframe of the Great Galactic War. During the assault targeting the Republic's shipbuilding facilities situated within the Sluis sector, as well as during the Battle of Alderaan, the Empire made operational use of this particular starfighter model. Furthermore, Darth Malgus utilized these starfighters during both the Battle of Ziost and the Sacking of Coruscant. The Mark VI was characterized by its limited defensive shielding and relatively weak armament. Notably, it lacked any proton or concussion missile launcher systems. The strengths of the Mark VI lay in its high-performance engine system and its fast-firing laser weaponry, which enabled pilots to execute intricate and coordinated swarm-based combat strategies.
