Following a short period of replenishment at San Pedro Bay, "Fanshaw Bay" again returned to Okinawa, arriving off of the Sakishima Islands on 9 June to continue launching airstrikes. She continued these operations until 27 June, when she was assigned to Task Force 39, commanded by Rear Admiral Alexander Sharp. Consisting of 107 minesweepers, seven minelayers, and seven netlayers, the Task Force began minesweeping operations within the East China Sea, beginning on 5 July. "Fanshaw Bay", along with three other escort carriers, provided an aerial screen for the minesweepers, and launched strikes against targets situated around the mouth of the Yangtze River on 28 July. On 30 July, she withdrew from the operations, having assisted the minesweepers in clearing 404 mines over , with no loss in ships, despite the occasional Japanese submarine or plane.
