Dalek ship (Four Doctors)

In the year A10%?, a Dalek saucer was sent to Marinus, where the Daleks intended to erase the Voord from reality. However, the Voord were defended by the War Doctor, who deployed a chronic tripwire which accelerated the evolution of the Daleks within the saucer, reducing them to dust. As a result, the saucer crashed on Marinus' surface. (COMIC: Four Doctors)
