the destroyer hosted Mrs. James J. Cabot, the daughter of Capt. William R. Rush; and, in 1957, the ship cruised the Mediterranean with Naval Academy midshipmen embarked. In between the Mediterranean deployments, William R. Rush operated from the Arctic Circle to the Caribbean, homeported first at Newport, from 1954 to 1958, and then from Mayport, Florida, from 1958 to 1964. She twice penetrated north of the Arctic Circle, in the autumn of 1957 and late in 1960, both times on NATO exercises. 1960–1969 There were highlights of the ship's closer-to-home deployments as well. In the summer of 1960, the ship embarked 35 Naval Academy midshipmen and took part in operations off the eastern seaboard with the Atlantic Fleet. She visited Quebec City, Canada; Hamilton, Bermuda; and Poughkeepsie, New York, during the cruise. That autumn, the ship served on "barrier patrol" when Cuban Premier Fidel Castro threatened the Caribbean nations of Nicaragua and Honduras. Two years later, in the fall of 1962, after American reconnaissance planes discovered the presence of Soviet offensive missiles in Cuba, William R. Rush returned to the area and operated with TF 135 on the Cuban "quarantine" line from 20 October to 3 December. The ship was at sea continuously during that period, except for an availability alongside the destroyer tender from 12 to 17 November. William R. Rush departed Mayport, Florida on 22 June 1964 and arrived at the New York Naval Shipyard on the 26th. Once at the shipyard, the ship commenced a 10-month Fleet Rehabilitation and Modernization (FRAM) overhaul, at the completion of which she would resume her old classification, DD-714. William R. Rush departed New York on 30 April 1965. Homeported back at Newport, the modernized destroyer soon commenced regular operations with the Fleet, following essentially the same sort of schedule that she had pursued since commissioning in 1945. As a member of Destroyer Squadron (DesRon) 10, she operated off the eastern seaboard between Newport and Key West, Florida, assuming a new role as an antisubmarine warfare ship. Returning to Newport on 27 July 1965 from refresher training out of Guantanamo Bay and a week of providing services to the Fleet Sonar School at Key West, William R. Rush embarked 25 NROTC midshipmen for three weeks at sea with Royal Canadian Navy units on exercise "CANUS (Canadian and United States) SILEX 1-65." The ship then went back to Newport for availability alongside Yosemite
