On 10 February the ships sortied again, bound for Tokyo and subsequent support of the Iwo Jima landings. On the second day out, "Porterfield" rescued two pilots from the carrier "Cowpens" (CVL-25). The Fast Carrier Task Force penetrated to within 60 miles (110 km) of Tokyo without being attacked, and then retired toward Iwo Jima to provide direct support for the landings there. The carrier planes flew direct support missions until 23 February, when the group refueled and set course for Tokyo. During the Iwo Jima campaign "Porterfield" added another plane to her credit. The group prowled off the Japanese home islands for several days, striking almost at will.
