On 10 February, "Yarnall" left Ulithi with TF 38 to attack the Japanese home islands for the first time since the Halsey-Doolittle Raid and to provide strategic cover for the assault on Iwo Jima. For two days, 16 and 17 February, the skies over Tokyo rained death and destruction. On the 18th, "Yarnall" steamed south with the carriers to lend the marines a hand during the Iwo Jima landings. While TF 38 planes supported the assault, "Yarnall" protected their floating bases from enemy air and submarine attacks. She remained in the vicinity of the Volcano Islands until the 22d when she and the carriers again headed toward the Japanese home islands for another swipe at Tokyo on the 25th. Then, after rendezvousing with TG 50.8, the logistics group, TF 38 sent its planes to strike Okinawa on 1 March.
