The SS Augustus was an unseen Space Corps spaceship mentioned numerous times by the mechanoid Kryten as one of the spaceships he had served aboard in the past, possibly the first. In the episode "Ouroboros", Dave Lister recalls that the crew of the SS Augustus all died of old age, suggesting it was likely to have been on a long-term voyage. Kryten again mentioned the SS Augustus during "Duct Soup" when the crew roamed around the Starbug vents. He spoke of it along with the Nova 5 as ships where the crew "abandoned" him.
