Arriving on "Yankee Station" on 7 October, she conducted plane-guard and screen operations for assigned carriers. Aside from a short port visit to Hong Kong in late October, she remained there for the next two months, and was present when air strikes against North Vietnam were terminated on 1 November. Detached for two weeks on 13 December, "Carpenter" patrolled the waters south of Da Nang in support of coastal interdiction efforts as part of Operation Market Time. The warship also provided gunfire support for friendly riverine forces south of Chu Lai. Other than a period of Soviet trawler surveillance between 30 January and 2 February 1969, "Carpenter" remained on "Yankee Station" until 11 February, when she steamed to Subic Bay for refueling and upkeep. Departing that same day, the warship sailed for home and moored at Pearl Harbor on 1 March.
