"Turner Joy"'s fourth deployment to the western Pacific brought her three tours of duty off the coast of Vietnam and concluded with a visit to Australia. On 15 December, she departed Kaohsiung and headed for the coastline of the II Corps area of South Vietnam. The destroyer reached her zone of operations on the 18th and, for the next month, conducted shore bombardments in support of American and South Vietnamese troops operating ashore. She concluded that assignment on 17 January 1967 and headed for the Philippines. After two weeks of availability at Subic Bay and a five-day liberty visit to Hong Kong, "Turner Joy" returned to the Vietnamese coast on 10 February. For almost a month, she delivered gunfire support for troops ashore, this time in the I Corps zone of South Vietnam. That duty ended on 3 March, and a nine-day tender availability alongside in Sasebo, Japan, followed.
