Battle TARDIS

Battle TARDISes existed as the main form of TARDIS used in battle before the War with the Enemy and any other temporal wars. The Celestial Intervention Agency made significant use of them.

Their main weaponry were time torpedoes, which could be used to suspend other vessels in the Vortex.

The CIA used at least one Battle TARDIS to capture the Fifth Doctor after he had brought an elemental being to Stockbridge. (DWM: ''The Stockbridge Horror)

A flotilla of Battle TARDISes were sent to gather the Eighth Doctor and Charlotte Pollard for the fight against Anti-Time. The Doctor initially avoided them (BFA: Embrace the Darkness), but they eventually caught up to the Doctor's TARDIS and snared it with time torpedoes. (BFA: Neverland)

Over a million Battle TARDISes were used by the Time Lords in the Last Great Time War. (NSA: Peacemaker)
