Time torpedo

Time torpedoes were Time Lord weapons. They would freeze a target in time. Most Battle TARDISes carried time missiles, firing them from warp silos. They would create a halo effect when fired.

The Celestial Intervention Agency shot them at the Fifth Doctor to capture him for trial after allowing an elemental being to alter the timeline of Stockbridge. (COMIC: The Stockbridge Horror)

The CIA used them again when retrieving the Eighth Doctor and Charlotte Pollard for the fight against Anti-Time. (AUDIO: Neverland)

During the Last Great Time War, the Fifth Time Lord Battle Fleet fired time torpedoes on a Dalek fleet in the Tantalus Eye, destroying them. Karlax and the CIA used their TARDISes to fire time torpedoes at the Doctor's TARDIS, but the War Doctor had upgraded his TARDIS' sheilds so that they would have no effect. (PROSE: Engines of War)
