Dalek ship (Into the Dalek)

A Dalek flying saucer fought in the war against the Combined Galactic Resistance.

It chased Wasp Delta, piloted by Journey Blue and her brother, attempting to destroy it and kill the two. The Twelfth Doctor succeeded in rescuing Journey, but her brother died. After "Rusty" turned evil again, he sent out a distress signal from the Aristotle and the saucer docked with the ship, dispatching boarding Daleks to slaughter the crew. At first they were successful, but the efforts of the Doctor and Clara Oswald turned "Rusty" against his own kind once more and he slaughtered the other Daleks on board the Aristotle. "Rusty" then ordered the saucer to retreat, telling the crew that the humans had activated the Aristotle's self-destruct. Fearing destruction and believing their mission accomplished, the saucer retreated with "Rusty" joining the resistance to continue his campaign against his species. (TV: Into the Dalek)

After returning to the ship, Rusty managed to destroy it, being left adrift in its wreckage. The Daleks eventually recovered him, exiling him to the Dalek Asylum for his deviance. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
