Nautilus EX-USS O-12 (SS-73) 1917 3D MODEL

O-12 was laid down on 6 March 1916 by the Lake Torpedo Boat Company in Bridgeport, Connecticut and was launched on 29 September 1917.

O-12 spent much of her career as a unit of Submarine Division 1, based at Coco Solo, Panama Canal Zone.

Struck from the Naval Vessel Register on 29 July 1930, ex-O-12 transferred to the United States Shipping Board for conversion by the Philadelphia Navy Yard.

She was leased for one dollar per year to Lake and Danenhower, Inc, for use on Hubert Wilkins's and Lincoln Ellsworth's Arctic Expedition.

Following the expedition, O-12 was returned to the Navy Department.

On 30 November 1931 she was towed three miles down the Byfjorden (a Norwegian fjord just outside Bergen) and scuttled in 1,138 feet (347 m) of water.
