The facility became the site of a small space battle during Operation: Quick Strike when Rebel Alliance starfighters tried to intercept a consignment of newly built TIE Avengers while they were transferred from the factory to the ISD Dauntless by untrained workers.
The fate of the Sentinel installation is unknown. It is unlikely that the factory suffered any serious damage during the rebel attack, as it was not the target. However, even if it was not destroyed by the Rebels it is unlikely that Sentinel survived beyond the attempted coup by Admiral Zaarin shortly after this Rebel raid, as Zaarin had great success in his initial move of destroying all TIE Avenger production facilities.
The outcome of the space battle depends on the actions of the player.
