Webstar

Webstars were starships used by the Racnoss Empire during the Dark Times. They were made out of a thin, silk-like substance strengthened by Huon energy. Each was piloted by a single Racnoss, and the ship could teleport this Racnoss to and from the surface of a planet. It was capable of firing bolts of electricity from its eight points.

Possibly the last Webstar in existence was used by the Empress of the Racnoss during her wait for Earth to develop Huon energy. It was destroyed after its Huon particles were depleted and British Army tanks fired upon it on Christmas Eve 2007 (by the orders of the Master, under the pseudonym Harold Saxon, as Defence Minister). (DW: The Runaway Bride) In Donna's World's version of this event, the Webstar still attacked and was destroyed, but the Doctor died while drowning the Racnoss. (DW: Turn Left)

Saxon also made mention of the Webstar and the death and destruction it had caused during his address to the British people concerning the Toclafane. He referred to it as the Christmas Star. (DW: The Sound of Drums)
