On 28 January 1973, the Vietnam cease fire was announced, and "Worden" joined TF 78 at Subic Bay. During the sweeping of Haiphong harbor, she functioned as Rear Admiral Brian McCauley's flagship as well as the helicopter support platform, the repair and logistic facility for the minesweeping units, and task force antiair warfare and surface defense. For later operations, the frigate served on antiair picket station and as the Positive Identification and Radar Advisory Zone (PIRAZ) station. Besides the inherent responsibility for aircraft control and identification and air surveillance, "Worden" functioned as search and rescue asset coordinator and platform for the pre-positioned helicopter.
