Die US Navy vermietete das USS O-12 in den späten 1920er Jahren für eine Jahresmiete von einem Dollar an Lake and Danenhower, die es dem Briten Hubert Wilkins für eine Polarexpedition zur Verfügung stellen durften. Lake and Danenhower, das Nachfolgeunternehmen der Bauwerft, rüstete das U-Boot für eine Unterquerung des Nordpols um und benannte es in Nautilus.
In the late 1920’s, accomplished explorer Sir Hubert Wilkins became convinced that a submarine would provide the ultimate means of reaching the North Pole. A submarine could travel for extended periods beneath the ice, avoiding the extreme hazards above which had caused earlier expeditions to fail. Carrying the latest scientific equipment, the submarine’s crew could conduct valuable meteorological, oceanographic, biological, magnetic, and spectrographic experiments.
Wilkin’s submarine would be called the Nautilus. It was a retired WW1-era submarine that had been extensively modified by renowned Naval Architect Simon Lake. The Nautilus featured a heavily reinforced bow, a shock absorber and sledge runners to protect it from collision with sea ice. A diving compartment and airlock was also added to allow divers to explore the depths while the submarine remained submerged. Most importantly, the Nautilus was fitted with three ice drills, allowing the submarine to recharge batteries, refresh air and even allow the crew to exit while the submarine still remained below the ice.
The Nautilus and her crew of 20 men began their expedition to the North Pole in June of 1931.
None of them realized how grueling their journey would be, and almost immediately things began to go wrong.
