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.) (TV: State of Decay)

History
Rassilon ordered the construction of bowships, (TV: State of Decay) though he may have taken the idea from someone else, (PROSE: Interference) during Gallifrey's war with the Great Vampires. (PROSE: A Brief History of Time Lords) He piloted a Bowship against the Great Vampires and drove them from the galaxy. (PROSE: The Multi-Faceted War)

Bowships were given artificial intelligence, which ultimately played against the Time Lords. Some wanted compensation before attacking a Great Vampire. (AUDIO: The Scent of Blood)

Of the almost 700 bowships that went into this war, only 34 returned. (PROSE: The Scrolls of Rassilon)

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

The Eighth Doctor encountered a Bowship near Edinburgh during the 1890s. (AUDIO: The Scent of Blood)

Bowships were time-scooped for use in the Last Great Time War. (PROSE: A Brief History of Time Lords) They could not prevent the Fall of Arcadia. (PROSE: A Prologue)

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

Arriving in the Capitol after escaping the Cyberman invasion of Karn, the Twelfth Doctor, asked for the bow-ships to be scrambled, only to find Rassilon, allied with the Cybermen. (COMIC: Supremacy of the Cybermen)

A damaged Bowship crashed into Terebek, and dragged the entire asteroid along with it as it performed time jumps. Jenny managed to repair it and used it to find the Twelfth Doctor. (COMIC: The Lost Dimension)
