Black Fleet
From Tardis Wiki, the free Doctor Who reference
The Black Fleet was the name given to an armada that consisted of at least eight Dalek worships. These starships were involved in a number of attacks conducted by the Dalek Empire against the Earth Alliance for at least six months. These assaults began on the outer fringe colonies which saw the entire world of Sifranos exterminated. Humanity was unaware of who this attacker was and the Black Fleet participated in the invasion of Earth in 2157. Upon entering the star system, the fleet attacked Void Station Cassius and destroyed it after which they blanketed the region by forming a subspace blockade in order to prevent any ships or supplies from reaching Cassius.
