SS America was an ocean liner built in 1940 for the United States Lines and designed by the noted naval architect William Francis Gibbs. She carried many names in the 54 years between her construction and her 1994 wrecking, as she served as the SS America (carrying this name three different times during her career), the USS West Point, the SS Australis, the SS Italis, the SS Noga, the SS Alferdoss, and the SS American Star. She served most notably in passenger service as the SS America, and as the Greek-flagged SS Australis for Chandris. In 1941, she carried two Nazi spies from the Duquesne Spy Ring in her crew: Erwin Wilhelm Siegler and Franz Joseph Stigler.
