In 1958, the Navy's nuclear — powered submarine Nautilus surfaced in the Greenland Sea after a 1.830 — mile journey, under the polar ice park, from the Pacific to the Atlantic Ocean. A Number of surface ships had sailed between those oceans, either via the Northwest Passage, close to the island of the Canadian Arctic, or via the Northeast Passage, along the northern coasts of Europe and Asia; the Nautilus, however, was the first ship to go from ocean to ocean via the North Pole.
The Nautilus ; 96 hours, sailed an almost direct course under the ice, travelling a greater part of the way at a depth of 400 feet and a speed of 20 knots. The submarine was bellow the ice, which in general is only from 7 to 14 feet thick, though stalactites sometimes reach depths of 125 feet.
This voyage effectively brought to the world's attention the potential role of nuclear — powered submarines, capable of prowling beneath the polar pack and launching missiles from any of the countless lagoons and channels of open water that divide it.
The submarines also seems to have been designed to offset the effect of the Soviet sputniks on word opinion. Although the Nautilus did not come back empty — handed from the scientific point of view, the voyage was as much a demonstration of potential as if was a potential expedition. Undoubtedly, much more was learned about the polar pack by those aboard fhe two American and two Soviet ice borne, scientific, stations then adrift in the Arctic ocean than by the group that manned the Nautilus.
