About this time, intelligence reports convinced Admiral Chester Nimitz that the enemy sought to take Port Moresby, on the southeastern coast of New Guinea, and he resolved to thwart those designs. He sent TF 11, built around a refurbished "Lexington" and led by a new commander, Rear Admiral Aubrey W. Fitch, to join Fletcher's TF 17 in the Coral Sea. "Astoria" returned to sea with TF 17 on 27 April to rendezvous with TF 11. The two carrier task forces met in the eastern Coral Sea early on the morning of 1 May.
