- You may be looking for War TARDIS.
Battle TARDISes were the usual type of TARDIS used in battle. Contrary to the Doctor's Type 40 and other conventional TARDISes designed for time travel without the threat of attack and for scientific research and exploration missions, these TARDISes were equipped with heavy armaments to engage in battle at a second's notice while being flown into hostile locations. The Celestial Intervention Agency made significant use of them.
Their outer plasmic shells were composed of living metal, able to morph into shields and any number of predetermined gun emplacements. (PROSE: Engines of War) Their main weaponry were time torpedoes, which could be used to freeze time and thus suspend other vessels in the time vortex. (AUDIO: Neverland)
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 (AUDIO: Embrace the Darkness), but they eventually caught up to his TARDIS and snared it with time torpedoes. (AUDIO: Neverland)
Over a million Battle TARDISes were used by the Time Lords in the Last Great Time War. (PROSE: Peacemaker) Cardinal Ollistra travelled to Synthesis Station in a battle TARDIS. (AUDIO: Day of the Vashta Nerada) A flotilla of Battle TARDISes were destroyed by Dalek stealth ships near the Tantalus Eye. Rassilon later sent another flotilla to the Eye to deploy the Tear of Isha. (PROSE: Engines of War) On the final day of the war, Priyan stated that every Battle TARDIS had been destroyed.
