On 10 December, "Hobby" sortied with the fast carriers of Task Force 38 for strikes on the important Philippines target of Luzon. She remained with the carriers through further strikes on the Philippines, Formosa, and the China coast into 1945, as U.S. naval power pushed closer to Japan. On 16 February, "Hobby" joined Admiral Marc Mitscher's fast carriers of the 5th Fleet as they carried out the first air strikes against Tokyo since the Doolittle Raid of April 1942. In addition to screening tankers for the carrier force, she operated off Iwo Jima and later off Okinawa as part of the valuable tankers ASW screen. Detached from Pacific duty at the end of June, "Hobby" arrived Seattle on 17 July 1945 for overhaul. News of the Japanese surrender reached her while she was in drydock.
