The carriers turned south late in the afternoon of the 17th to prepare to support the amphibious landings on Iwo Jima on 19 February. TG 58.1 was refueling on the day of the landing, but joined the other task groups providing close support for the Marines ashore on the 20th. Three days later, Spruance released the fast carriers to attack the Japanese Home Islands again in an attempt to neutralize the kamikaze threat. Bad weather limited the effectiveness of the airstrikes around Tokyo on 25 January; continued bad weather forced the cancellation of the airstrikes planned the following day despite moving southwards overnight. Mitscher refueled his ships on the 27th and turned south to attack Okinawa on 1 March before returning to Ulithi on the 4th. American claims were 52 aircraft shot down and more than 60 destroyed on the ground in exchange for 55 aircraft lost to all causes between 19 February and 1 March.
