Scout ship
From Tardis Wiki, the free Doctor Who reference
Scout ships were reconnaissance craft that could be detached from a mothership. The Hydrax had three scout ships fronted with bolts of steel. One of these was used by the Fourth Doctor to impale and kill the King Vampire. (TV: State of Decay)
The Sontarans had spherical scout ships that each contained a single Sontaran. (TV: The Time Warrior)
