Dalek warship
From Tardis Wiki, the free Doctor Who reference
In an account of the Last Great Time War in which the conflict was ended by the Eighth Doctor, concentric rings of Dalek warships surrounded the planet Gallifrey before they and the planet were destroyed by the Moment. (PROSE: Doctor Who and the Time War) These vessels were saucer-shaped. (TV: The Day of the Doctor, COMIC: Weapons of Past Destruction)
