Dalek shuttle

The Dalek shuttle was a shuttlecraft used by the Daleks to travel from their ships to the surfaces of planets. The shuttle was docked on the Dalek Mothership and left through a hatch on the ship's underside.

The shuttle could hold four Daleks and had heavy ground defences while having an unguarded service hatch on the top of the hull. Beneath the hatch was a control room where a Dalek was connected into the system. In November 1963, Imperial Daleks used a Dalek Shuttle to reach Earth to find the Hand of Omega for their emperor, Davros, before the Renegade Daleks did for the Dalek Supreme.
