The new destroyer sailed 4 February 1946 for shakedown training in the Caribbean. She returned to her homeport, Newport, in April, and was occupied for the next few months in Naval Reserve Training. Arriving Norfolk 8 October, the ship joined Admiral Leahy's flagship Wisconsin BB-64, and other units for a cruise to Chile and Venezuela. She transited the Canal twice on this voyage, and was reviewed by the President of Venezuela 25 November 1946. Joseph P. Kennedy, Jr., returned to her home port 14 December 1946.

During 1947 the destroyer operated on the East Coast and in the Caribbean.

During this period of great unrest in Europe, the fleet carried out the important role of peacekeeper and stabilizer. Joseph P. Kennedy, Jr. visited various Mediterranean ports before arriving Newport 26 June 1948. The remainder of the year was spent in antisubmarine exercises and the first half of 1949 saw her make two training cruises to the Caribbean.

The ship sailed 23 August 1949 for 6th Fleet duty as flagship of Destroyer Squadron 18, returning 27 January 1950.

She departed 8 April for the Formosa Patrol, helping to prevent further hostilities across the volatile Straits.

Joseph P. Kennedy, Jr., then returned to Korea arriving off Wonsan 20 May to take up bombardment station in support of the Allied siege and occupation of harbor islands. This duty continued until 13 June, a period of almost constant bombardment of great importance to the operation, after which the ship steamed to Sasebo.

Joseph P. Kennedy, Jr., did not return to the West Coast immediately upon the termination of this combat duty, but instead steamed westward to complete a circuit of the globe. With other units of Destroyer Squadron 8, she visited Singapore, Bahrein, Port Said, Naples, and Gibraltar before returning to Newport 9 August 1951. Until January 1953 she conducted battle practice and served as school ship for the Fleet Training School at Newport that serves well to keep the fleet abreast of the latest developments. She sailed 7 January for another 6th Fleet cruise, returning to Newport 18 May 1953.

She then arrived New York 1 July 1961 for a FRAM ( Fleet Rehabilitation and Modernization ) overhaul in the Naval Shipyard. During this period she received the latest in antisubmarine gear, a new helicopter flight deck and hangar aft, and numerous other modifications designed to increase greatly her useful life. After emerging in her new dress in late May 1962, she underwent exhaustive shakedown out of Guantanamo Bay, Cuba returning 26 August 1962.

She departed Newport 29 April 1964 for another Med cruise until 26 August, and in October was underway for Operation "Steel Pike I", one of the very largest amphibious operations since World War II. During the passage of the task force to the Spanish coast, she acted as antisubmarine screening ship. Joseph P. Kennedy, Jr. returned to Newport 19 November 1964.

Late in January of 1965, Joseph P. Kennedy, Jr., put to sea for Port Canaveral, Fla., where she helped qualify two newly constructed Polaris submarines for patrol over seas. There followed a regular 3-month overhaul in the Boston Naval Shipyard.

Comdr. J. W. Hayes took over command of Joseph P. Kennedy, Jr., from Capt. J. V. Peters on July 14; the next day, a 2-month period of refresher training commenced as the ship set sail for Guantanamo Bay, Cuba.

The U.S. Man In Space Program was one of Joseph P. Kennedy, Jr.'s most recent commitments; leaving Newport on November 27, 1965, the ship took station 1,200 miles southeast of Bermuda as part of the afloat recovery team for Gemini 6 and 7 on a 14-day orbital and rendezvous mission in space. The shots a success and her duty done, Joseph P. Kennedy, Jr. returned to Newport 21 December to prepare for another deployment in the Mediterranean.

Assigned to DesRon 10, Joseph P. Kennedy, Jr departed Newport 15 February 1966 for duty with the 6th Fleet.

She completed her peace-keeping patrols late in June and returned to Newport 8 July.

During the remainder of the year she conducted destroyer exercises and carrier screening operations off the eastern seaboard. In mid-November she participated in recovery operations following the successful 4-day flight of Gemini 12. On 1 March 1967 Joseph P. Kennedy, Jr. again sailed for duty with the mighty 6th Fleet. She cruised the Mediterranean until late April, thence transited the Suez Canal for the Red Sea and Indian Ocean. Late in June she departed the Gulf of Aden for the United States.
