The frigate, as part of the 7th Fleet, assisted in the evacuation of Americans from Vietnam as part of Operation "Frequent Wind." As the operation came to a close on 3 May, "Worden" returned to Thailand to resume her port visit. However, the capture of the SS "Mayaquez" by the Cambodians on 13 May interrupted her stay; and she sailed for Hong Kong. "Mayaquez" was freed before "Worden" reached the British crown colony, so the frigate proceeded to Yokosuka, arriving there on 20 May.
