The destroyer parted company with the carrier shortly after midnight on 30 July in response to orders to return with HMAS "Hobart" to "Sea Dragon" duty off Vietnam. On 8 August, she reentered Yokosuka once more for a brief respite from combat duty. From there, she moved to Subic Bay with a task force built around the carrier and, after three days in the Philippines, headed back to Vietnamese waters. During that tour of duty, she provided escort and plane-guard services to "Coral Sea" and, later, to the carrier . Before returning to Yokosuka on 17 October, the warship participated in a series of ASW exercises, visited Hong Kong, and conducted surveillance of Russian trawlers operating in the vicinity.
