may 4, 1942 - Battle of Coral Sea
Coral Sea was the world’s first all-carrier battle, and the first sea battle in which neither side could see the other. Both the U.S. and the Japanese navies thought they understood how to fight using carriers. Both discovered they were wrong. At the end of this painful learning experience, the United States had lost the 41,000-ton carrier Lexington, while Japan had lost only the 11,000-ton carrier Shoho.
