In a change of pace from her usual route, the guided missile destroyer followed a great circle route through the northern Pacific and the Bering Sea before arriving at Pusan, South Korea, on 1 September. After an ASW exercise with units of the Japanese Maritime Self-Defense Force at mid-month, and another ASW exercise with South Korean warships in mid-October, "Berkeley" sailed south for the Philippines on 7 November. Following a brief stop at Subic Bay to refuel, the warship conducted Exercise "Burgonex 86" with the Royal Brunei Armed Forces between 15 and 23 November. Afterwards, she visited Pattaya Beach, Thailand, and then made a "freedom-of-navigation" demonstration off the coasts of Kampuchea and Vietnam in early December. "Berkeley" then stopped at Hong Kong and Subic Bay for port visits, before ending the year on her way to Chinhae, South Korea.
