"Oliver Mitchell" and "Lawrence C. Taylor" were detached to TG 38.2 of the Fast Carrier Task Force between 2 and 6 January 1945 to screen the fleet carriers as they launched strikes on Formosa and Luzon in support of the invasion of Lingayen Gulf. While returning to TG 30.7, a broken shaft disabled her sonar, preventing effective anti-submarine operations and relegating her to providing plane guard duty for "Anzio". As a result, the commander of CortDiv 72 transferred his pennant to "Lawrence C. Taylor" on 10 January. On the next day, "Oliver Mitchell" was detached from TG 30.7 to return to Ulithi in company with two destroyers and an oiler, arriving two days later. At Ulithi, the ship was drydocked for sonar repairs and remained there for the rest of the month. The commander of CortDiv 72 returned his pennant to her when TG 30.7 returned to Ulithi on 28 January.
