. The ice extended as much as 60 feet (18.3 m) below sea level. During the initial attempt to go through the Bering Strait, there was insufficient room for the submarine to pass between the ice and the sea bottom. During the second, successful attempt to pass through the Bering passage, the submarine passed through a known channel close to Alaska (this was not the first choice way through the Bering Strait as the submarine wanted to avoid detection).

The trip beneath the ice cap was an important boost to America as the Soviets had recently launched Sputnik but had no nuclear submarine of their own. During the address announcing the journey the president mentioned that one day nuclear cargo submarines might use that route for trade.

Noise

The hull and superstructure of
Nautilus vibrated sufficiently that sonar became ineffective at more than 4 knots (7.8 km/h) speed. Also, noise generation is extremely undesirable in submarines as this makes the vessel vulnerable to detection. Lessons learned from this problem were applied to later nuclear submarines.

Presidential Unit Citation

For outstanding achievement in completing the first voyage in history across the top of the world, by cruising under the Arctic ice cap from the Bering Strait to the Greenland Sea.

During the period 22 July 1958 to 5 August 1958, U.S.S. NAUTILUS, the world's first atomic powered ship, added to her list of historic achievements by crossing the Arctic Ocean from the Bering Sea to the Greenland Sea, passing submerged beneath the geographic North Pole. This voyage opens the possibility of a new commercial seaway, a Northwest Passage, between the major oceans of the world. Nuclear powered cargo submarines may, in the future, use this route to the advantage of world trade.

The skill, professional competency and courage of the officers and crew of NAUTILUS were in keeping with the highest traditions of the Armed Forces of the United States and the pioneering spirit which has always characterized our country.
