Returning to "Yankee Station" on 5 July, "Berkeley" spent the next two weeks working on the northern SAR station. Heading south on 18 July, the warship passed through the Strait of Malacca and moored at Penang, Malaysia, for a port visit on 23 July. Following four days there, and just over a week in Singapore for upkeep, "Berkeley" returned to the Vietnam war zone on 7 August. Assigned to a naval gunfire support mission, the warship cruised off Cua Viet for the next three weeks in support of friendly forces near the demilitarized zone (DMZ). During this time, she fired 2,143 5-inch rounds at enemy targets. After a brief stop at Subic Bay, the guided-missile destroyer retraced her path across the Pacific and arrived in Long Beach on 16 September.
