Bowship

Bowships were warcraft used by the Time Lords in their war against the Great Vampires. (PDA: The Infinity Doctors, EDA: Interference - Book Two)

Armaments & History
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.) As most of the details of the Vampire War existed only as legendary fragments, little was known of the exact specifications of Bowship construction. (DW: State of Decay)

Bowships were later used in the Last Great Time War. (DWAN: Doctor Who Annual 2006)
