Dalek spaceship (Daleks' Invasion Earth 2150 A.D.)

A Dalek spaceship, commanded by a Red Dalek, on behalf of the Gold Dalek, oversaw the Daleks' occupation of Earth in 2150. Tom Campbell described it as a flying saucer.

When Dr. Who and his companions arrived in 2150, the saucer transported a fresh group of Robomen to the mine in Bedfordshire. When sabotage resulted in the magnetic forces of the Earth's core being unleashed against the Daleks, the ship took off in an attempt to escape but its engines were unable to counter the magnetism and it crashed. (NOTVALID: Daleks' Invasion Earth 2150 A.D.)

The Dalek Survival Guide indicated that this version of the Dalek Invasion Force was from a version of reality "B" relative to the First Doctor's version of reality "A". (PROSE: Dalek Survival Guide)

Behind the scenes
A drawing of this "saucer" appeared on the cover of the Doctor Who and the Dalek Invasion of Earth novelisation even though the book's content drew from the television version.

The comic prequel Daleks Versus the Martians features a similar saucer.
