The 1966 Soviet submarine global circumnavigation was announced to be the first submerged around-the-world voyage by a group of Soviet nuclear-powered submarines. The voyage was an early example of blue-water operations by the Soviet Navy`s nuclear-powered submarine fleet, and it paved the way for future operations during the latter half of the Cold War. The voyage took place nearly six years after the first complete submerged circumnavigation of the world undertaken by the U.S. Navy`s nuclear-powered submarine Triton in 1960. Technically speaking, this Soviet submerged around-the-world voyage was not a true "circumnavigation" since the submarine group went from the Soviet Northern Fleet in the area of the Kola Peninsula to the Soviet Pacific Fleet base in Kamchatka and consequently did not go completely around the world as did the USS Triton.
