The U.S. aircraft returned and landed on their carriers by 13:38. By 14:20, the aircraft were rearmed and ready to launch against the Port Moresby Invasion Force or Gotō's cruisers. Fletcher was concerned that the locations of the rest of the Japanese fleet carriers were still unknown. He was informed that Allied intelligence sources believed that up to four Japanese carriers might be supporting the "MO" operation. Fletcher concluded that by the time his scout aircraft found the remaining carriers it would be too late in the day to mount a strike. Thus, Fletcher decided to hold off on another strike this day and remain concealed under the thick overcast with fighters ready in defense. Fletcher turned TF 17 southwest.
