Tusk left New London on January 18, 1960 and conducted ship to ship exercises with USS Entemedor (SS-340) out of Norfolk, VA. On January 23-25, 1960 she welcomed visitors at City Pier #5 in Washington DC. March 1960 found Tusk participating with USS Tench (SS-417) in the artic for Operation ICEX and visiting Halifax, Nova Scotia. Six years elapsed between her 1954 northern Europe assignment and her second Mediterranean cruise late in 1960. During this cruise (July 6-7, 1960) she participated in a Joint Naval exercise with three Portuguese Frigates (Nuno Tristao, Diogo Gomes and Corte Real) visited Oporto, Portugal (July 8-11, 1960) to help celebrate "Navy Day" events and commemoration ceremonies related to the 500th anniversary of Prince Henry the Navigator. Later visiting Rota, Spain; Malta; Genova, Sardegna, Livorno, Fiumicino during the Olympic games, Naples, Sicily, Cagliari, Italy and Gibraltar. One event of that cruise was a submerged collision with the USS Independence CVA-62, destroying the Tusk's forward torpedo boom and capstan and damaging the teak decking. Tusk returned to New London in December 1960 for a 6 week upkeep repairing engine #4 by replacing 2 broken crank shafts.
The fall of 1961 brought another round of NATO exercises followed by joint American-Canadian training operations in the western Atlantic. January 1962 found Tusk in upkeep prior to heading north with SKATE (SS-578) and ENTEMADOR (SS-340) for SUBICEX 1-62. One purpose of the exercise was to train SKATE for a rendezvous at the North Pole in the summer with the SEA DRAGON coming from Pearl Harbor. After ICEX Tusk conducted local operations going to Halifax and Bermuda for liberty until entering Philadelphia Naval Shipyard in July 1962. This yard period was a major overhaul for TUSK. All 4 engines, all 4 generators, and all 4 main propulsion motors were removed from the ship and taken to the shop for complete overhaul. Number 4 engine was scrapped and an overhauled replacement engine was placed aboard. The superstructure from the sail aft was replaced with the new plastic clamshell superstructure. She received a new periscope with built in electronic sextant for taking star sights submerged. Toward the end of the overhaul, an experimental sonar was placed aboard just forward of the sail.
Another three-year period of New London-based local operations occurred before she was deployed again to Europe in the fall of 1964 for more NATO training. TUSK entered the Philadelphia Naval Shipyard in June 1965 to undergo a major overhaul. Her configuration was changed with the addition of a new high plastic conning tower fairwater, the purpose of which is to provide room for more electronic masts, provide easier visual observation of the deck, and greater comfort for the TUSK's watchstanders. In addition, TUSK received the PRAIRIE-MASKER system, increased air-conditioning capacity, additional storerooms, and additional fresh water tanks. Upon completion of overhaul in January 1966, TUSK was transferred from Submarine Squadron TEN to Submarine Squadron EIGHT. During the spring and summer of 1966, Tusk returned to the Mediterranean for her third tour of duty with the 6th Fleet, visiting Gibralter- Valletta, Malta- Naples- Patrais- Greece- Barcelona and Palma, Mallorca. August 1966 brought a resumption of duty in American coastal waters which lasted until early 1967.
During the summer of 1967, the submarine returned to northern European waters, visiting Holy Loch, Scotland; Portsmouth, England; Cherbourg, France; Bremerhaven, Germany; Aarhus, Denmark; Goteborg, Sweden; Londonderry, Northern Ireland; and participating in yet another series of multinational NATO exercises. That November, she joined in binational American-Canadian exercises in the western Atlantic before resuming her east coast routine. The boat spent the summer of 1968 in the Philadelphia Naval Shipyard for an extensive overhall where the batteries were replaced, engines removed and rebuilt, all systems were gone over and boat was painted inside and out, later conducting services with nuclear-powered submarines Jack (SSN-605) and Lafayette (SSBN-616).
January 27, 1969 until March 10 she participated in Operation Springboard visiting San Juan and Roosevelt Roads, Puerto Rico, Charlotte Amalie, St. Thomas, V.I. On July 7, 1969 she made her fourth deployment to the Mediterranean, traveling across the Atlantic with USS Sea Owl (SS-405) and USS Irex (SS-482) arriving in Rota, Spain on July 19. She spent 4 days in Gibralter B.B.C. and conducted exercises with the Sixth Fleet. August 15-19, 1969 found Tusk in dry dock in Rota followed with trips to Naples, Italy and Palma de Mallorca, Spain.Returning to east coast operations in October. On December 1, 1969, TUSK was transferred to Submarine Squadron TWO.
