Bowship

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

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

As most of the details of the Vampire War exist only as legendary fragments, little is known of the exact specifications of Bowship construction. (DW: State of Decay)

Bowships were later used in the Last Great Time War, although their effectiveness against Dalek technology would have been limited at best.
