Under the leadership of Gial Ackbar, who held the rank of Admiral, a fleet belonging to the Alliance to Restore the Republic saw action throughout the Galactic Civil War after Alderaan's destruction. The MC80 Liberty Type Heavy Star Cruiser called Aurora served as the fleet's flagship, receiving backup from a minimum of nine CR90 corvettes, seven EF76 Nebulon-B escort frigates, five GR-75 medium transports, and also Echo Squadron. During 0 BBY, this fleet played a role in the escape of a convoy of Alderaanian refugees from the Galactic Empire which was occurring at the Fostar Haven space station.
