Once cargo freighters, several stripped down ships were given by the Sullustans to the Virgillian Free Alignment Forces to aid them in the Virgillian Civil War. In turn, the Virgillians converted the cargo hold into a hangar, as well as installing stolen Imperial-grade shields and weapons. At the conclusion of the Virgillian Civil War, and once the Imperial presence was removed from the system, the Virgillian Alignment donated their fleet of carriers to the Rebel Alliance shortly before the Battle of Endor.
This is a favourite of mine and so I just had to model and texture her. She is a frigate sized ship that I like to think would be the Rebellions anti-fighter frigate much in the same way that the Imperial have the Victor. However rather than have anti-fighter weaponry as it's main focus, it uses fighters to counter Imperial and enemy fighters.
