Hubert Wilkins, with financing from the coal heir Lincoln Ellsworth, undertook a series of expeditions including an attempt to reach the North Pole by submarine. The expedition leased the submarine O-12 from the USN and refitted her to include an arched topside that could slide under the polar ice cap, and an auger to bore holes for the snorkel.
She was 175 feet long, 560 tons and diesel powered. The batteries could run her about 125 miles.
Aptly, she was renamed Nautilus.
After a series of misadventures, the expedition was abandoned and she was scuttled in Norway.
She was able to go about as far as 80 N.
The nuclear submarine USS Nautilus encountered similar problems in her initial trips under the ice cap. Significant damage to the sail and the periscopes was made by ice projecting down that the rather primitive upward looking depth sounders did not detect. Also, open leads or polynyas were far fewer and more distant apart than was supposed. That made navigation difficult as gyrocompasses did not function well at that latitude, and LORAN was not usable unless surfaced, and even then celestial navigation was more accurate. She reach the pole on August 3rd, 1958. USS Skate did the same on August 11th, although neither surfaced.
USS Skate returned on March 17th, 1959 and as Subfixer correctly reported, committed Wilkins' ashes to a location at or about the North Pole.
Over to you, sir.
