"Hollister" entered the Puget Sound Naval Shipyard on 15 March 1961 for FRAM (Fleet Rehabilitation and Modernization) overhaul, remaining there through the end of the year for an addition of a helicopter deck and hangar aft. After refresher training, she departed Long Beach, California on 7 June 1962 for duty with the 7th Fleet. This cruise came after the Laos crisis and Communist insurgency threatened Thailand.
