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)
