 etween New Guinea and Australia\, while combat aircraft were sent to Port 
 Moresby to reinforce the base. The Japanese and American fleets struck at 
 each other by air for two days in the Battle of the Coral Sea. Neither sid
 e's ships ever got within gun range of each other.\n\nThe LEXINGTON was su
 nk and the YORKTOWN was badly damaged. The Japanese light carrier SHOHO wa
 s sunk\, and two larger Japanese carriers had to return to Japan for repai
 rs. The battle was tactically a draw\, but strategically an Allied victory
  because the Japanese drive on Port Moresby had been turned back. The Amer
 icans and Australians were able to ramp up their efforts to dislodge the J
 apanese from the northern regions of New Guinea.
