Nautilus (World Game)

The Nautilus was an early submarine constructed by Robert Fulton to demonstrate in front of Napoleon Bonaparte for his empire building.

The Nautilus itself was noted by the Second Doctor, who was on a mission for the Time Lords with the Time Lady Serena to stop the transdimensional Players from influencing and altering human history, for not being antiquated or comical in appearance, but modern and deadly. It was built from copper.

Fulton developed torpedoes propelled by compressed air, which was able to sink ships and were also powerful enough to destroy a Raston Warrior Robot.

The Countess helped in the construction of the Nautilus - originally the submarine was powered by hand, but the Countess supplied an Omega drive which would convert the submarine into a nuclear-powered vessel, but the Doctor was able to help when the drive destroyed the connections Fulton kept coming up with to connect the drive to the propeller.

The Nautilus was destroyed during a demonstration against a ship, although the Countess had originally planned to destroy the submarine anyway. (PROSE: World Game)

Behind the scenes
The Nautilus takes its name from the fictional submarine of the same name, from the novel 20,000 Leagues Under the Sea.
