"Berkeley" spent the spring of 1988 preparing for her next overseas deployment, on which she embarked on 6 July. In company with the battleship and TG 70.1, the warship took the great circle route to South Korea, arriving at Pusan on 24 July. The group participated in surface warfare exercises with the South Korean Navy before heading south to Subic Bay on 5 August. Following a short availability there, "Berkeley" detached from the task group and continued farther south, arriving in Darwin, Australia, on 26 August. As part of Australia's bicentennial celebration, the guided missile destroyer spent the next five weeks visiting ports on Australia's northern and eastern coasts. Starting with a visit to Cairns from 4 to 8 September, she moved on to stops at Townsville, Mackay, and Gladstone before putting into Sydney on 26 August for a week-long naval celebration with over 60 warships from 16 countries. "Berkeley" then made a visit to Bell Bay in Tasmania before rendezvousing with "New Jersey" on 18 October for the transit home, arriving in San Diego via Pearl Harbor on 9 November.
