Bowship

Bowships were warcraft used by the Time Lords in their war against the Great Vampires.

Armaments
The primary weapon of a bowship was a launcher firing a "mighty bolt of steel" capable of killing a Great Vampire if it pierced it through the heart. (Great Vampires absorbed attacks from directed energy weapons and rapidly regenerated damage from minor projectiles.)

Bowships were mentioned in the Record of Rassilon. (TV: State of Decay)

Bowships were used in the Last Great Time War. They could not prevent the Fall of Arcadia. (PROSE: A Prologue)

Rassilon was exiled from Gallifrey in a Bowship. (COMIC: Supremacy of the Cybermen)
