The Battle of 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 direct ship-to-ship combat, as planes launched from carriers attacked enemy ships. The battle was crucial in stopping the Japanese advance towards Australia and protecting Allied supply lines. Although both sides suffered losses, the United States managed to sink the Japanese aircraft carrier Shoho and damage others, marking a strategic victory that boosted Allied morale.
