D-Four
this was the designation of one of the Dreadnaughts that was part of the Outbound Flight starship. D-Four was the only Dreadnaughts which remained aboveground when the ship crashed into a large planetoid in the Redoubt, after it was attacked by a group of Chiss led by Thrawn. Thus, it was the only access point through which any visstor could reach the rest of the ship. However, because it was the only Dreadnaught aboveground, the Outbound Flight Colony expended a large portion of its efforts on getting D-Four ready for flight once again. When the remains of Outbound Flight were located by a Chiss-led expedtion some fifty years after its attack, D-Four was capable of flight but not ready for the Colony to continue its mission. This made it an attractive target for Estosh and Bearsh, who commanded their Vagaari pirates to steal the ship for their own use. After planting line creepers in the rest of the Outbound Flight Dreadnaughts, they blasted D-Four away from the main ship by destroying the turbolift pylons that connected them. The Vagaari hoped that this would kill anyone left on Outbound Flight, but Captain Talshib of the Chiss managed to seal them off. Estosh and his surviving Vagaari nearly reached the Brask Oto Command Station, the first stop in their attack on the Chiss, but Luke Skywalker and Mara Jade Skywalker managed to defeat them and bring the Dreadnaught under control.
