On 5 February, the warship reentered the lagoon at Ulithi. Upkeep occupied the next two weeks. On 19 February, the destroyer escort reported for duty with the U.S. 5th Fleet as an element of Task Unit (TU) 50.7.3. That same day, she departed Ulithi with that task unit and headed—via Guam—to the vicinity of Iwo Jima to support the battle then in progress for that island. For about a month, she and the other ships of the task unit conducted antisubmarine patrols of the sea lanes between the Marianas and Iwo Jima. On 11 March, she cleared the Iwo Jima area to return to her base at Ulithi where she arrived on 14 March.
