Implacable was the name given to an EF76 Nebulon-B escort frigate used by the Imperial Navy in a TIE/IN interceptor simulator mission.

The mission objectives were to destroy a Rebel supply base to draw the light Mon Calamari Cruiser Ardent into an ambush. Implacable would drop out of hyperspace before the supply depot and launch TIE Interceptors and TIE/sa bombers. The bombers would attack the space station AZ 77, while the interceptors would engage the Z-95 Headhunters that were defending the depot. When the Ardent arrived, the same Imperial forces would engage it as well.

The frigate would also participate in destroying three space platforms XQ1 Abriham, XQ2 Bersabba and XQ3 Cyrlus and then finally a Mon Calamari cruiser Ossus Day.
