In a remarkable feat of naval engineering and exploration, the USS Triton, a nuclear-powered radar picket submarine, set sail from New London, Connecticut, on February 16, 1960, embarking on the first-ever submerged circumnavigation of the globe. Under the command of Captain Edward "Iceberg" McClintock, the Triton was tasked with demonstrating the capabilities of nuclear power while also testing advanced navigational technologies. As the first vessel to complete a full journey around the world while submerged, Triton’s mission was both ambitious and groundbreaking. Departing under the cover of darkness, the submarine traversed the Atlantic Ocean, navigating through the icy waters of the Arctic Circle before making its way to the Pacific. The vessel’s innovative propulsion system allowed for extended underwater endurance, allowing it to avoid detection while running deep beneath the surface. The Triton’s historic voyage lasted 84 days, during which it covered approximately 26,723 nautical miles—all while submerged. Notably, the crew of 144 sailors faced numerous challenges, including prolonged isolation and the psychological strains of underwater living, while also showcasing the tactical and logistical prowess required for such a journey. Triton returned to its home port on May 10, 1960, completing its circumnavigation and marking a significant milestone in naval history. This extraordinary expedition not only solidified the USS Triton’s place in maritime lore but also underscored the potential of nuclear-powered vessels, paving the way for future submarines and innovations in underwater exploration. As the world watched, Triton’s successful journey heralded a new era in naval capabilities, demonstrating the extraordinary advancements in technology and the endurance of human spirit beneath the waves.
