If the Japanese took port moresby, they would have complete air superiority in northern australia, which would allow Japan to bomb cities like Perth, sydney, Brisbane or Canberra. Japanese air superiority would also allow for a Japanese invasion of australia, and if that were to happen, the Japanese could win the war in the pacific. The US after finding out, sent two carrier task forces; The first was led by the USS Yorktown and the second was led by the USS Lexington. The first task force decided to split off from the second and went to attack a small Japanese seaplane base. The task force destroyed a destroyer, a mine layer, and all of the seaplanes there, the task force then returned to the second after the attack. The Japanese thought that the carrier from the first task force had retreated into the area of the solomon islands, but the US carrier didn’t retreat to the solomon islands, and the opposing fleets were very far apart in fact. The next morning, the two fleets sent out search sorties to find one another. Some of the US search planes saw a small group of Japanese destroyers and light cruisers and thought that it was a part of the larger Japanese fleet. When the USS lexington and USS Yorktown heard about the small Japanese force, they sent sorties of bombers to attack the ships. On the way to the Japanese force, the bombers found the Japanese light carrier Shoho, and sank it after intense bombing. A small force of australian ships had been ordered to attack the larger invasion force and succeeded in driving the Japanese away from port moresby thus completing the allied objective. The Japanese had found out the whereabouts of the US carrier task forces but did not want to attack at night
