On 6 March, "Albert David" departed Iloilo on the island of Panay to return to Vietnamese waters. This time, however, her mission was a peaceful one. She was part of Operation End Sweep, the removal of mines from North Vietnamese waters. Her participation in that effort punctuated by port visits to Sasebo in Japan, Subic Bay in the Philippines, and Hong Kong lasted until the second week in June. The warship cleared Vietnamese waters on 9 June, visited Keelung on Taiwan on 12 and 13 June, and arrived in Yokosuka on the 17th. Two days later, the ocean escort returned to sea for the voyage back to the United States. She made brief stops for fuel at Midway Island and Pearl Harbor before reaching Long Beach on 3 July.
