Manned by a United States Coast Guard crew, Carson City departed Los Angeles, California, on 19 July 1944, for Espiritu Santo and Milne Bay, New Guinea, where on 13 August 1944, she reported for patrol and escort duty in the New Guinea area with the United States Seventh Fleet.

On 22 October 1944, she accompanied her charges into the landing area, and next day began a voyage escorting the empty ships back to Humboldt Bay.

After reaching Humboldt Bay, Carson City resumed convoy escort duty in the New Guinea area, shuttling to Wakde, Biak, Noemfoor, Sansapor, Morotai, and Mios Woendi until 26 November 1944, when she departed New Guinea for Pearl Harbor, Territory of Hawaii, where she underwent an overhaul.
