Sailing south, "Berkeley" arrived in Subic Bay on 11 November. After a two-week availability there, she moved to the Tabones training range to keep up her gunnery prowess. On 30 November, in response to a coup attempt against the Aquino government in Manila, the warship put to sea with the Enterprise battle group for contingency operations. As the crisis eased, "Berkeley" detached from the battle group on 12 December and sailed east to Thailand. En route, the guided missile destroyer took part in more "freedom-of-navigation" missions off Vietnam and Kampuchea, before arriving at Pattaya Beach on 14 November. After four days there, the warship moved on to Singapore for a week of upkeep.
