USS Triton Circumnavigates the Globe | Naval History Blog

May 10, 1960

(Link in title) The USS Triton completes a submerged circumnavigation of the globe in only 84 days.  The mission was called Operation Sandblast and was a first in history.  The sub followed routes taken by Magellan, making the voyage even more historically relevant.  At the time, the Triton was the largest and most expensive submarine the world had ever known.
