After striking Tulagi, "Yorktown" rejoined with "Lexington", and the two carriers engaged the rest of the Japanese forces involved in the "Mo" operation from 6–8 May in the Battle of the Coral Sea. In the battle, "Lexington" was sunk and "Yorktown" was damaged. The Japanese suffered "Shōhō" sunk, a fleet carrier heavily damaged, and heavy losses to their carrier aircraft and aircrews. Fearing more damaging attacks from Allied land-based aircraft or warships and unable because of their aircraft losses to provide adequate air cover for their naval surface forces, the Japanese turned back from their planned assault on Port Moresby with the intention of trying again later. The next Japanese seaborne attempt to take Port Moresby, however, never happened, mainly because of their navy's defeat in June at the Battle of Midway. Instead, the Japanese decided to try to take Port Moresby in an ultimately unsuccessful overland attack along the Kokoda Track. The failure to take Port Moresby in May 1942 would have significant and far-reaching strategic implications, many of which involved the small Japanese naval base at Tulagi.
