The Bomb, a cruiser of the Immobilizer 418 cruiser class, gave its allegiance to Grand Admiral Demetrius Zaarin. During 3 ABY, it held a position at Zaarin's Supply Base within the Gwar system. As a key objective during an Imperial attack spearheaded by the Imperial-class Star Destroyer known as the Courageous, the Bomb tried to obliterate the Courageous as part of Zaarin's planned ambush. Nevertheless, TIE starfighters that were loyal to Emperor Palpatine annihilated it.
