Australasia 1942: Battle of the Coral Sea
After conquering the East Indies, Japan shifted its focus to cutting Australia's supply line to America. In May, it attempted to send an invasion fleet to occupy Port Moresby, but ran into an American carrier force in the Coral Sea. The ensuing battle was dominated by aircraft carriers, with neither side's ships sighting each other.

18 Apr 1942 Doolittle Raid▲
Sixteen US Army Air Force B-25B Mitchell medium bombers were launched beyond fighter escort range from the US Navy's aircraft carrier USS Hornet in the western Pacific Ocean, flying on to bomb the Japanese capital Tokyo and other places on the island of Honshu. Fifteen of the bombers carried on to land in China - landing a medium bomber on an aircraft carrier being impossible - with the 16th landing in Vladivostok, Soviet Union. The success of the mission demonstrated the vulnerability of Japan and was a major morale boost for the US.
4–8 May 1942 Battle of the Coral Sea▲
In preparation for Operation MO - the intended Japanese landing at Port Moresby, New Guinea - a Japanese naval force, including two fleet carriers and one light carrier, advanced into the Coral Sea to hunt down US carriers known to be operating there. Over the next few days, they fought the first naval engagement in which neither side's ships sighted each other, with Japan losing the light carrier Shōhō and taking damage to the fleet carrier Shōkaku, and the US losing the fleet carrier Lexington and taking damage to the fleet carrier Yorktown. Although the US losses were worse, Japan was forced to abandon Operation MO.
