Operation Sea Orbit was the 1964 around-the-world cruise of the United States Navy's Task Force One, consisting of USS Enterprise (CVAN-65), USS Long Beach (CGN-9), and USS Bainbridge (DLGN-25). This all-nuclear-powered unit steamed 30,565 miles unrefuelled around the world for sixty-five days.

USS Enterprise (CVN-65), formerly CVA(N)-65, is a decommissioned United States Navy aircraft carrier. In 1958, she was the first nuclear-powered aircraft carrier and the eighth United States naval vessel to bear the name. Like her predecessor of World War II fame, she is nicknamed "Big E". At 1,123 feet (342 m), she is the longest naval vessel ever built and the only ship of a class that was originally planned to have five other ships. Her 93,284-long-ton (94,781 t) displacement ranks her class as the third largest carrier class, after the Nimitz class and the Gerald R. Ford class. Enterprise had a crew of some 4,600 service members.
