Artificial satellite (The Secret of the Emperor)
From Tardis Wiki, the free Doctor Who reference
An artificial satellite in orbit of the planet Uranus was home to an Earth colony. During the Invasion of Uranus, the satellite used supersonic waves to wreck a fleet of Dalek galactic ships. It was later determined by Dalek Scientists that the Golden Emperor sustained damage during this incident, observing that his sonic guard was cracked. (COMIC: The Secret of the Emperor)
