( www.MaritimeCyprus.com ) On August 3, 1958 , the USS Nautilus made history by completing the world's first undersea transit across the geographic North Pole. Submerging near Point Barrow, Alaska, the vessel traveled nearly 1,000 miles beneath the Arctic ice cap, pioneering a revolutionary sub-ice route connecting the Pacific and Atlantic Oceans. Construction and Launch of the World's First Nuclear Submarine The story of the USS Nautilus began under the leadership of Captain Hyman G. Rickover , an engineer who assumed control of the U.S. Navy’s nuclear propulsion program in 1947. Driven by a vision to revolutionize naval warfare, Rickover delivered the world's first atomic-powered vessel years ahead of schedule. Key Milestones in the Building of the Nautilus: Keel Laid: June 1952, by U.S. President Harry S. Truman. Christened & Launched: January 21, 1954, by First Lady Mamie Eisenhower in Groton, Connecticut. Commissioned: September 30, 1954. First Atomic Operation: January 17, 1955. Specifications and Atomic Capabilities Unlike conventional diesel-electric submarines, the nuclear-powered Nautilus possessed virtually unlimited underwater endurance. Because its nuclear engine required no oxygen and consumed minimal fuel, it eliminated the need to surface frequently to recharge batteries. Specification Details Length 319 feet Displacement 3,180 tons Power Source Uranium-powered nuclear reactor Underwater Speed In excess of 20 knots Operation Northwest Passage: The Journey to the Pole On July 23, 1958 , under the command of Commander William R. Anderson , the Nautilus departed Pearl Harbor, Hawaii, to embark on "Operation Northwest Passage." The crew comprised 116 men, including 111 officers and crew members alongside four civilian scientists. Entering the Arctic: The submarine navigated north through the Bering Strait and submerged near Point Barrow, Alaska. Under the Ice: On August 1, the Nautilus dove beneath the Arctic ice cap, maintaining a depth of approxima
