She returned to Subic on 22 October. During this tour, she transferred over 226 tons of foodstuffs during underway replenishments. Her second line period saw the ship transfer 290 tons of provisions to ships with task force TF 77 on Yankee Station. Bangkok, Thailand, provided welcome relief for liberty parties before the ship returned to the line a third time on 29 November. Operating in support of "Market Time," "Vega" transferred some 392 tons of food -- Christmas supplies—to ships engaged in the daily interdiction patrols of the sea lanes. Further, the ship delivered some 67 tons of supplies to Danang, Camranh Bay, Con Son, An Thoi, and Hon Choi—all in South Vietnam. After visiting Hong Kong from 13 to 21 December, "Vega" spent Christmas at Kaohsiung, Taiwan, and then returned to Subic Bay to load supplies. Before the year was out, the supply ship was underway again—for her fourth line period off Vietnam. During this swing, the ship transferred 300 tons of food to ships on "Yankee Station" and "Market Time" patrols. Many sailors on the ships she supplied probably enjoyed the fresh fruit acquired on Taiwan during the ship's visit there prior to deploying off the Vietnam coastline. The supply vessel conducted two more swings on the patrol line in the sea lanes off Vietnam into early 1971. Extremely difficult weather conditions hampered such operations on 29 and 30 January 1971, but the men on the ships involved rose to the occasion and accomplished the successful transfer of 100 tons of food without incident. Offloading 342 tons of supplies at the Naval Supply Depot, Subic Bay, from 8 to 10 March, the ship departed the Philippines to visit Japan. While en route, however, "Vega" was dispatched to search for a Japanese fishing vessel in distress off Yonakuni Jima. Conducting the search in heavy seas and beneath leaden grey overcast skies, "Vega's" efforts were uncrowned with success, as she found no trace of the distressed ship. "Vega" eventually visited Sasebo, from 17 to 20 March, before she got underway for Pearl Harbor, en route to her ultimate destination of Alameda, California. Making port at the Naval Air Station, Alameda, on 6 April, "Vega" later served from 13 to 17 May as host ship at San Francisco for HMCS "Terra Nova". "Vega" then entered Triple "A" Shipyard, San Francisco, on 27 May for a restricted availability which increased the ship's transfer capabilities.
