After a somewhat lengthy wait at Eniwetok occasioned by the unexpectedly difficult task of rooting out the defenders of Saipan, "Winged Arrow" returned to the island on 19 July and retracted units of the 2nd Marine Division for the Tinian assault. On the morning of 24 July, she and several other ships carried that division, made up of the 2nd and 8th Marine Regiments, around to the southwestern coast of Tinian opposite Tinian Town where they feigned a landing to draw enemy forces from the real objective on the eastern coast. Upon concluding the feint, "Winged Arrow" transported the marines back around to waters off the actual invasion beaches where they remained in the floating reserve. On the 26th, they went ashore to reinforce and support the 4th Marine Division during the reduction of Tinian.
