returned to the waters off the coast of Vietnam. There, she engaged in nearly continuous rearmings of a host of ships, including the attack carriers, Ranger, Constellation, and the veteran , with Task Force 77. These operations were part of the ship's regular routine that alternated load-in operations at Subic Bay with replenishment work during line deployments in the South China Sea and Tonkin Gulf. The end of January 1969 found the ship enjoying a temporary pause in her hectic schedule, undergoing a period of tender overhaul alongside the repair ship at Sasebo, Japan. Returning to Subic Bay soon thereafter, Wrangell loaded ammunition to return to the "line", in February. After a series of routine rearmings near the Demilitarized Zone (DMZ), rough weather and high seas frustrated several attempts by the destroyer to come alongside. Since the destroyer's magazines were low, the need to replenish her stocks was urgent; so Wrangell and George K. MacKenzie anchored inside the sheltered lee of Cam Ranh Bay to effect the transfer. While nearby patrol craft periodically dropped antiswimmer charges and kept a lookout for possible Viet Cong interference in the operation, the job was completed in two hours. As the ship's history for the year stated: "For Wrangell, the Camranh Bay episode was the closest she had ever brought her thousands of tons of ammunition to hostile fire. All hands breathed a sigh of relief when the exciting, risky rearming of the MacKenzie was over." Back in Subic Bay on 10 April, Wrangell turned over ammunition ship duties to and headed for home two days later. However, before she could complete the voyage, North Korean fighters shot down an EC-121 reconnaissance plane over the Sea of Japan. The resulting crisis saw a show of American naval force in that area – a presence that Wrangell supported. Wrangell transported ammunition from Sasebo to Yokosuka to Sasebo again before heading for Pearl Harbor on 3 May. During her recently completed deployment, she had supplied ammunition to ships ranging from the battleship New Jersey to the Coast Guard cutter , transferring nearly 12,000 tons of that necessary commodity. Port visits included Subic Bay, Hong Kong, Singapore, Sasebo, Yokosuka, Pearl Harbor, Acapulco and the Panama Canal before the ship eventually arrived back at her home port, Charleston, on 10 June 1969. After repairs and underway training evolutions during the summer, Wrangell departed Charleston on 6 October, standing
