The day Nautilus traveled under the North Pole – level 3


On August 3, 1958, the United States Navy submarine Nautilus became the first submarine to successfully pass under the North Pole.

The Nautilus was also the world’s first nuclear-powered submarine. The submarine was named after Jules Verne’s famous fictional submarine, which was described in his novel Twenty Thousand Leagues Under the Sea.

The submarine departed from Pearl Harbor, Hawaii, and headed to the Bering Strait. Then it submerged and traveled 2,940 km under the Arctic ice cap before emerging near Greenland. The journey under the ice cap took 96 hours.

Difficult words: league (three miles), Bering Strait (water between Russia and Alaska), submerge (to go under water), emerge (to go above the surface of the water).

What technologies did the Nautilus use to successfully navigate under the icy Arctic waters?
