The USS Triton, a nuclear submarine in the U.S. Navy, embarked on Operation Sandblast, an ambitious mission to achieve the world's first submerged circumnavigation of the globe. Setting off from New London, Connecticut, the Triton, under the command of Captain Edward L. Beach Jr., began the journey with a crew of 111. This unprecedented voyage was aimed at demonstrating the capabilities of nuclear submarines during the tense atmosphere of the Cold War, emphasizing the importance of naval power in global affairs.

The Triton's voyage spanned a total distance of approximately 26,723 nautical miles and took 84 days to complete. During this time, the submarine navigated through critical international waters, showcasing the effectiveness of U.S. naval tactics and technology. The mission's operational secrecy, combined with its extensive geographic reach, allowed the U.S. Navy to assess global maritime routes and potential strategic locations.

This groundbreaking undertaking received significant media attention and was marked by various international events, including the ceremonial launch of a documentary that followed the Triton's progress. As the submarine completed its route back to the United States, it solidified its place in naval history, affirming the U.S. Navy's advancements in underwater warfare and exploration, and highlighting the evolving role of submarines in military strategy and global security.
