Tusk completed her shakedown cruise in the southern Atlantic with a round of goodwill visits to Latin American ports.
She called at Rio de Janeiro and Bahia in Brazil, Curaçao in the Netherlands West Indies, and at Colón in the Panama Canal Zone before returning to New London, Connecticut, in June.
Her sail was streamlined and enlarged to house the snorkel, a device added to allow her to operate on diesel power at periscope depth and to recharge her batteries while running submerged.
She conducted her shakedown training and made a simulated war patrol to the Panama Canal Zone in June and July.
That fall and winter, Tusk resumed normal operations, participating in exercises with other United States and NATO forces.
Tusk rushed to the aid of the stricken submarine, providing medical supplies for Cochino's injured by way of life rafts.
That assignment, punctuated by regular exercises with the fleet, continued until the summer of 1952 when she returned to an operational unit, Submarine Squadron (SubRon) 10.
Normal East Coast duty out of New London lasted until late in the year at which time Tusk was deployed to the Mediterranean Sea for a six-month tour with the Sixth Fleet.
During the summer of 1967, the submarine returned to northern European waters, visiting several ports and participating in yet another series of multinational NATO exercises.
Throughout 1968 and during the first half of 1969, the ship continued New London based operations, including services to nuclear-powered submarines Jack and Lafayette.
After almost three years of that New London-based routine, including an overhaul at the Charleston Navy Yard from July to December 1971, Tusk set out for her fifth and final tour of duty with the Sixth Fleet.
The submarine rounded out the final year of her career with normal operations along the eastern seaboard, primarily in the New England vicinity.
Ex-Tusk was commissioned into the Republic of China Navy as Hai Pao (meaning "seal"), first with hull number SS-92, then SS-794, and finally SS-792.
