Dreadnaught-Six, often shortened to D-Six, represented the sixth heavy cruiser of the Dreadnaught-class; it was one of six such vessels employed in the creation of Outbound Flight.
This warship was delivered straight from the shipyards belonging to Rendili StarDrive to be put into service for the project in 27 BBY. Following the exploratory vessel's crash into the Redoubt and the subsequent formation of a colony by the Survivors, the Jedi Quarantine was then put in place.
