Coral Sea
In World War II the Battle of the Coral Sea was the first aircraft carrier battle fought between the United States and Australia against Japan. The battle lasted from 4 May to 8 May 1942.  During that time none of the ships saw each other or fired their guns at each other.  All the fighting was done by aircraft from the carriers. It is the largest naval battle fought near Australia.  It was important because it stopped the Japanese from invading Port Moresby, the capital city of New Guinea.  Many people regarded it as the battle that saved Australia.
