Stand down continued into January 1970. On 21 January, she began a restricted availability at the Bethlehem Steel shipyard located in San Francisco. Repairs complete on 16 February, "Virgo" moved back to Concord to load ammunition in preparation for operations at sea along the west coast. Refresher and type training occupied her time until 7 May at which time she departed San Francisco for the last western Pacific deployment of her Navy career. "Virgo" arrived in Subic Bay on 29 May and embarked upon the first of six line periods supplying ammunition to warships off Vietnam. She completed her final line swing early in November and, after a stop at Sasebo, she got underway for home on 27 November. She arrived back at Concord on 12 December and began preparations for decommissioning. "Virgo" was decommissioned at Vallejo, California, on 18 February 1971, and her name was once again stricken from the Navy List. Subsequently transferred to the Maritime Administration for disposal, she was sold on 19 November 1973 to Taipei Hsieh, of Taiwan, for scrapping.
