Sierra entered the Norfolk Naval Shipyard on 27 March 1962 for conversion under the FRAM II program.
Sierra was out of the yard and able to resume her normal work routine on 15 September.
From 1963 through December 1973, Sierra serviced ships of the fleet at ports along the United States East Coast, but primarily at Norfolk.

On 5 January 1974, she moved to Charleston, South Carolina, which became her home port for the next few years.
During that time, Sierra made two peacetime Mediterranean cruises in 1977 and 1978/79 and visited Spain, Majorca, mainland Italy, Sicily, and the French Riviera.
 Her home port, for both cruises while in Italy, was Naples.
