4-8 May 1942
The significance of air power on the sea is highlighted in the first naval battle in history, pitting aircraft carriers against aircraft carriers. Although each side loses a carrier (the Lexington and the Shoho), the US Navy defeats the Japanese navy in the Battle of the Coral Sea. The US notches a strategic victory in the battle in the sea southeast of New Guinea and northeast of Australia. Japan is flustered in its drive to extend battle lines southward toward Australia.
