Red October (submarine)

Red October (Russian: Красный Октябрь, "Krasniy Oktyabr" ) is a fictitious modified Typhoon class submarine in the Tom Clancy novel The Hunt for Red October and the film that followed. She was built with a revolutionary stealth propulsion system called a "caterpillar drive", which is described as a pump-jet system in the book. In the film however, it is shown as being a magnetohydrodynamic drive.
