The Battle of the Coral Sea was a significant naval battle fought from May 4 to May 8, 1942, during World War II. It was primarily between the naval forces of the United States and Japan. This battle marked the first time in history that aircraft carriers engaged each other without the ships directly seeing one another, as planes launched from carriers conducted the attacks. The battle was fought near the Coral Sea, northeast of Australia, and aimed to stop the Japanese advance towards Port Moresby in New Guinea. Although both sides suffered losses, the battle is considered a strategic victory for the Allies, as it halted Japanese expansion in the Pacific.
