USS O-12 (SS-73), also known as "Submarine No. 73", was one of 16 O-class submarines of the United States Navy commissioned during World War I.

Laid up in reserve by the US Navy, in 1924, the submarine was leased for use in Arctic exploration in 1930, sponsored by William Randolph Hearst. Renamed Nautilus, the submarine suffered significant damage while exploring the Arctic, in 1931, and while having recorded significant data while there, Hearst considered the venture a failure. She returned to Norway, to repair the damage, and the submarine was returned to the USN there, they had the submarine towed down a fjord and scuttled, in November 1931.

Design

The later O-boats, O-11 through O-16, were designed by the Lake Torpedo Boat Company, to different specifications from the earlier boats designed by Electric Boat. They did not perform as well, and are sometimes considered a separate class.Template:Sfn The submarines had a length of Template:Cvt overall, a beam of Template:Cvt, and a mean draft of Template:Cvt. They displaced Template:Convert on the surface and Template:Cvt submerged. The O-class submarines had a crew of 2 officers and 27 enlisted men. They had a diving depth of Template:Cvt.Template:SfnTemplate:Sfn

For surface running, the boats were powered by two Template:Convert Busch-Sulzer diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Template:Convert Diehl Manufacture Company electric motor. They could reach Template:Convert on the surface and Template:Cvt underwater. On the surface, the O class had a range of Template:Convert at Template:Cvt.Template:SfnTemplate:SfnTemplate:Sfn

The boats were armed with four 18-inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The O-class submarines were also armed with a single [[3"/23 caliber gun|Template:Cvt/23 caliber]] retractable deck gun.Template:Sfn

Construction

O-12Template:'s keel was laid down on 6 March 1916, by the Lake Torpedo Boat Company, in Bridgeport, Connecticut. She was launched on 29 September 1917,Template:Sfn sponsored by Mrs. Marguerite Cummings, wife of Homer S. Cummings,Template:Sfn and commissioned on 18 October 1918.Template:Sfn

Service history

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

When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-73.Template:Sfn

In 1921, she was awarded a Battle Efficiency Pennant and trophy for gunnery (gun and torpedo). She decommissioned on 17 June 1924, after just five and a half years of service, and was placed in reserve at the Philadelphia Naval Yard.Template:Sfn

Nautilus Arctic Expedition

Template:See also Struck from the Naval Vessel Register on 29 July 1930, ex-O-12 transferred to the United States Shipping Board (USSB), for conversion by the Philadelphia Navy Yard.Template:Sfn She was leased at the rate of one dollar per year to Lake and Danenhower, Inc., of Bridgeport, for use on Hubert Wilkins's and Lincoln Ellsworth's Arctic Expedition of geophysical investigation.Template:Sfn The lease required that she either be returned to the Navy for disposal, or scuttled in at least Template:Cvt of water.

On 24 March 1931, she was re-christened Nautilus. As Prohibition prevented the use of an alcoholic beverage, she was baptised not with the traditional champagne but rather with a bucket of ice cubes.Template:Sfn Great French writer Jules Verne's grandson was present at the event, under the French flag, along with Sir Hubert's new-wed wife, actress Suzanne Bennett.Template:Sfn

Simon Lake furnished Nautilus with several pieces of scientific equipment designed for under-ice operations. One was a mechanical probe, much like a trolley pole, that would scrape along the bottom of the ice cap to indicate how much clearance the submarine had below the ice.Template:Sfn Another included drills, supposedly capable of cutting through Template:Cvt of ice, to reach fresh air.Template:Sfn The vessel's torpedo chamber was converted into a moon pool, when its water-tight door was closed, pressure was equalized, so a trap door could be opened, allowing the lowering of scientific instruments. These innovations were tested only cursorily before the boat put to sea.Template:Sfn

Nautilus, with her crew of 20 men, was commanded by Captain Sloan Danenhower, son of John Wilson Danenhower, who served aboard Template:USS during her Arctic expedition.Template:Sfn On 4 June 1931, Nautilus began the crossing from New York City, United States, to Plymouth, England. The first leg of the voyage that was planned to take them up the coast of the North Sea, to Spitsbergen, and conclude with a dramatic rendezvous at the North Pole with the German airship Graf Zeppelin. On that first leg, however, Nautilus encountered a violent storm. Both engines failed, leaving the boat adrift. She was rescued, and initially towed into Cork Harbor, in Southern Ireland, on 22 June, where her batteries were re-charged, before being towed to England, by Template:USS, where she was repaired.Template:Sfn

On 5 August 1931, very late in the year to begin an Arctic expedition, Nautilus began making her way through the English Channel, and along the Norwegian coast. Another storm again damaged the boat, carrying away her bridge and giving her a permanent list, but after a stop in Tromsø, on 11 August, she successfully reached Spitsbergen, where Wilkins allowed only a single day for repairs.

The crew carried out the planned scientific experiments as they pushed on northward, but thick pack ice hindered their progress. The boat was ill-equipped to deal with the extreme cold, lacking insulation and heaters. The fresh water system froze and the hull developed slow leaks.

After ten days, Nautilus reached the 82nd parallel north, the farthest north any vessel had reached under its own power, and preparations began to dive and proceed under the ice. However, the boat refused to respond; the stern planes had been carried away at some unknown earlier time. Without them, the submarine could not control its depth while submerged, and the expedition had to be aborted.

On 31 August, under financial pressure from newspaperman William Randolph Hearst, who had initially promised to pay for the expedition, but who indicated by telegraph that Wilkins would not be paid if he did not continue, Wilkins ordered the submarine onward. Captain Danenhower ordered Nautilus trimmed down by the bow, and deliberately rammed an ice floe in an attempt to force the boat under. The manoeuver worked, in that Nautilus submerged, and became the first submarine to operate under the polar ice cap. However, her unconventional method of diving caused significant damage to her upper works. She was out of radio contact for days, was presumed lost, and rescue efforts were planned. In fact, she had actually travelled only a short distance under the ice before resurfacing through a polynya, but her radios had been badly damaged, requiring days to repair.

The scientific crew continued their experiments, and their findings became the first paper published by the Woods Hole Oceanographic Institution. On 20 September, Nautilus returned to Spitsbergen, carrying invaluable data and with all crew alive. Hearst, however, considered the expedition a failure and carried out his threat, refusing to pay for the expedition.

Fate

Following the expedition, O-12 was returned to the Navy Department.Template:Sfn On 20 November 1931, she was towed Template:Convert down the Byfjorden, a Norwegian fjord just outside Bergen, and scuttled in Template:Cvt of water. In 1981, Norwegian divers found her wreck.

In 1959, Template:USS was the first submarine to surface at the North Pole, and the second submarine, after Template:USS in 1958, to reach the North Pole. Her crew conducted a tribute to Sir George Hubert Wilkins, and scattered his ashes over the North Pole.

In 2010, the research submersible JAGO dove to try to locate and inspect Nautilus.Template:Sfn
