Survey Ship Delta

Survey Ship Delta was the saucer used by a contingent of Daleks sent on a mission to travel through Earth's history and analyse how humans made war so that weaknesses could be found and exploited in future conflicts with the Daleks. They called this mission the Dalek Project. This saucer was equipped with new time-drive systems and got caught in a Vortex storm. It landed in 1908, collided with Survey Ship Sigma and was destroyed on the wastelands of Siberia when the damaged time drive exploded and destroyed Daleks inside it. According to the Eleventh Doctor, that saucer left no survivors. (COMIC: The Dalek Project)
