Beginning on 7 May, the carrier forces from the two sides exchanged airstrikes over two consecutive days. The first day, the U.S. sank the Japanese light carrier Shōhō, while the Japanese sank a U.S. destroyer and heavily damaged a fleet oiler (which was later scuttled). The next day, the Japanese fleet carrier Shōkaku was heavily damaged, the U.S. fleet carrier Lexington was critically damaged (and was scuttled as a result), and the Yorktown was damaged. With both sides having suffered heavy losses in aircraft and carriers damaged or sunk, the two fleets disengaged and retired from the battle area. Because of the loss of carrier air cover, Inoue recalled the Port Moresby invasion fleet, intending to try again later.
