"Abnaki" completed the overhaul on 19 September and returned to San Diego the next day. Refresher training followed in October; and, at the beginning of November, she resumed west coast operations out of San Diego. During December 1974 and the first part of January 1975, she prepared for overseas duty. On the 11th, the tug weighed anchor to begin her voyage to the Far East. She made only one stop – at Pearl Harbor from 20 to 22 January – before arriving in Subic Bay on 9 February. Two days later, she got underway to participate in Readex 1–75 conducted in the South China Sea. Following that exercise, "Abnaki" visited Yokosuka and Sasebo in Japan. In March, she made a four-day liberty call at Hong Kong followed by a visit to Singapore. She returned to Subic Bay early in April but, on the 10th, got underway for Vung Tau where she salvaged the cargo door of a C-5A cargo plane which had crashed shortly after takeoff from Tan Son Nhut Air Base. After participation in Operation Frequent Wind — the evacuation of Saigon — "Abnaki" returned to Yokosuka on 15 May for three weeks of upkeep before heading for the Marianas on 8 June. The tug arrived at Guam on 13 May, loaded supplies destined for the natives of the Marshall Islands, and put to sea again on the 16th. After dropping the supplies off at several of the smaller atolls in the Marshalls, she continued on via Pearl Harbor to San Diego where she arrived on 13 July.
