The first submarine to travel under the North Pole was the USS Nautilus, a nuclear-powered sub from the United States. In 1958, it made history by becoming the first vessel to reach the geographic North Pole, traveling completely underwater. The journey was top-secret at the time and called “Operation Sunshine.”

After successfully navigating the icy waters, the Nautilus resurfaced in the Pacific Ocean. This mission proved submarines could operate in extreme conditions, even under the polar ice cap.

The achievement was a major milestone in both naval history and Arctic exploration!
