Connecticut built the sub that sailed under the North Pole—and you can walk through it today

USS Nautilus’s Historic Arctic Crossing Under Ice

The USS Nautilus changed how we fight wars at sea.

In 1951, Congress backed a bold plan for the world’s first nuclear sub, led by Polish-born Captain Hyman Rickover.

President Truman laid its keel in 1952 at Groton, Connecticut. By 1954, it was ready. On January 17, 1955, Commander Wilkinson sent a simple message: “Underway on Nuclear Power.”

Then came the big test. In August 1958, Nautilus and its 116-man crew slipped under Arctic ice for Operation Sunshine.

After 1,830 miles deep below the surface, they did what no ship had done before – crossed the North Pole.

The historic submarine now rests in Groton, where visitors can walk through the very vessel that made underwater history.

Rickover Built America’s Nuclear Navy

Congress approved the world’s first nuclear submarine in July 1951. Captain Hyman Rickover, who came to America from Poland as a kid, led the charge.

He joined the Navy’s atomic program in 1946 and fought for nuclear submarines. President Truman started construction at Electric Boat Shipyard in Connecticut on June 14, 1952.

The new technology would let submarines stay underwater much longer than old diesel boats that needed to come up for air often.

The Nautilus Made a Big Splash

First Lady Mamie Eisenhower christened the USS Nautilus on January 21, 1954, with thousands watching.

The Navy put the submarine into service on September 30, 1954, with Commander Eugene Wilkinson in charge. Nautilus was 319 feet long with a 28-foot beam and ran on a nuclear reactor.

Unlike diesel subs that needed to surface regularly, Nautilus could stay underwater for months, only coming up when food ran low or crews needed a break.

Nuclear Subs Changed Everything

Commander Wilkinson sent a simple message on January 17, 1955: “Underway on Nuclear Power.”

The Nautilus then traveled 1,381 miles underwater from New London to Puerto Rico in just 89.8 hours. No sub had ever gone so far or stayed down so long before.

Nuclear submarines could move around underwater without coming up for fuel or air, making them hard for enemy ships to find.

America Wanted to Top the Soviets

The Soviet Union launched Sputnik in October 1957, shocking Americans. President Eisenhower wanted to show America still led in science and engineering.

The Navy came up with a bold plan to send a submarine under the North Pole ice cap, something nobody had done before.

The White House approved Operation Sunshine as a top-secret mission that would take a sub through one of the harshest places on Earth.

The Sailors Got Ready for Ice

Commander William Anderson led Nautilus with 116 men for the polar trip. Arctic expert Waldo Lyon came along to help with ice navigation.

The Navy added special sonar that looked upward to check ice thickness above the submarine. Crew members practiced for emergencies like getting stuck under thick ice.

They loaded extra food and supplies for the risky journey through waters no submarine had ever crossed.

The Secret Trip Started in Hawaii

Nautilus left Pearl Harbor on July 23, 1958, heading north. The crew couldn’t tell anyone where they were going.

Commander Anderson steered toward Point Barrow, Alaska, the northernmost spot in America and the gateway to the polar ice cap.

The crew checked weather reports and ice conditions as they moved into colder waters. Once under the ice, they would be cut off from the rest of the world.

The Sub Slipped Under Arctic Ice

The Nautilus went under at Point Barrow on August 1, 1958, starting its risky journey beneath the ice cap.

The submarine stayed between 400 and 500 feet deep to avoid ice ridges that hung down like underwater mountains.

The special sonar constantly checked overhead, showing how thick the ice was above them. Complete darkness wrapped around the submarine as it pushed through the freezing Arctic waters.

They Reached the North Pole

Commander Anderson spoke over the ship’s speakers at 11:15 PM Eastern Time on August 3, 1958: “For the world, our country, and the Navy—the North Pole.”

The Nautilus had just crossed the exact North Pole, becoming the first vessel ever to reach this spot. The crew members smiled and shook hands in their tight quarters.

No ship had ever reached the pole before, and they did it completely underwater.

The Sub Popped Up in the Atlantic

Nautilus traveled 1,830 miles under the Arctic ice pack during the crossing.

The submarine finally came to the surface between Greenland and Spitzbergen on August 5, 1958, ending its record-breaking underwater journey.

Anderson sent a coded message to Washington about their success. The crew kept quiet about what they had done until the government shared the news.

Submarines could now go anywhere in the world’s oceans, even under polar ice.

Eisenhower Celebrated the Crew

President Eisenhower told the world about the North Pole crossing on August 8, 1958. He gave Commander Anderson the Legion of Merit at the White House.

The entire crew got the Presidential Unit Citation, the first time this award went to a military unit during peacetime.

The mission changed how navies thought about submarine operations forever.

Groton Keeps the Nautilus Story Alive

The Nautilus served the Navy for 25 years, going on countless missions and training exercises.

The Navy finally decommissioned the submarine on March 3, 1980, after it traveled more than 513,000 miles. The historic vessel returned to Groton, Connecticut.

Today, visitors can tour the Nautilus at the Submarine Force Museum and walk through the actual submarine that changed naval warfare and made history at the North Pole.

Visiting Groton, Connecticut

You can explore the USS Nautilus and Submarine Force Museum at 1 Crystal Lake Road in Groton for free.

Bring photo ID since it’s near the Naval Submarine Base. The museum is open Wednesday through Monday, 9am-4pm in winter and 9am-5pm in summer.

You’ll learn about Admiral Hyman Rickover’s nuclear navy revolution and see the submarine that first crossed under the North Pole in 1958.

Groups of 25 or more need advance reservations.
