Hammer was an IPV-1 System Patrol Craft belonging to the Galactic Empire. It was stationed at Quesna Base for guard duty when Ace Azzameen, along with Dunari, came to rescue his brother Emon, who was imprisoned there at the time. They delivered a container of tibanna, which had been booby trapped, and it provided cover for Dunari as he boarded the station and rescued Emon. The Hammer, along with all the TIE/LN starfighters and Assault Gunboats present, were destroyed in the ensuing chaos.
