Dalek saucer commander

The Dalek Saucer Commander was the designated commander of the Dalek flying saucer in Bedfordshire during the 22nd century Dalek invasion of Earth. Unlike Dalek drones the Saucer Commander had a black dome and black and silver slants and served as the second-in-command to the Supreme Dalek. The Commander, along with the Supreme Dalek and the Dalek fleet, was destroyed at the climax of the story by the uprush from the exploding penetrative explosive capsule (TV: The Dalek Invasion of Earth)

A Dalek Saucer Commnander led a saucer destroy satellites during the Cold War, hoping the Americans and the Russians would blame each other and the conflict would escalate. It exterminated a Dalek for questioned an order. However, the Dalek saucer was infiltrated by the Third Doctor who contacted a submarine, the HMS Pandora, and ordered it to fire on the ship. The Daleks, including the Saucer Commander died as the ship flooded (COMIC: The Threat from Beneath)

Behind the scenes

 * The prop for this Dalek is the same prop for the Supreme Dalek. The production team didn't paint it in time for the show as seen during the attack on the saucer - the commander went in but the supreme came out - for it was not seen during the second part of part 2 and the rest on the episode.
 * In the remake of The Dalek Invasion of Earth starring Peter Cushing, the Saucer Commander's roles are taken up by a Red Dalek.
