Passage:Flint reported to the 3rd Fleet for duty at Ulithi on 27 December 1944, and six days later, sailed with Task Force 38 (TF 38) for a month-long cruise in support of the invasion of Luzon. She screened aircraft carriers as they launched strikes on Luzon, Taiwan, and the China coast, and fired protective anti-aircraft cover during a Japanese kamikaze attack on 21 January 1945. Replenishing at Ulithi from 26 January to 10 February, Flint then sailed with newly designated TF 38 for air strikes on Tokyo preceding the attack on Iwo Jima. Her force arrived off Iwo Jima on 21 February to provide anti-aircraft cover for the Marines who had landed two days previously, and Flint returned to Ulithi 12 March for a brief 2 days of replenishment.
