Eighty-three years ago today, on May 8, 1942 (March 24, 1942), both Japan and the United States suffered heavy losses in the Battle of the Coral Sea. The USS Enterprise ushered in a new pattern of American naval warfare May 8, 1942. Both the United States and Japan claimed victory after a fierce air-to-sea battle in the Coral Sea. For the first time in the history of naval warfare, the ships of the two sides did not directly engage in battle. The two warships never even met, but only served as a take-off and landing ground for carrier-based aircraft to carry out offensive operations. During the battle, the US military successfully prevented the Japanese from landing at Tulagi in the Solomon Islands and Port Moresby in New Guinea, but at a high cost. " The USS Lexington was sunk and the USS Yorktown was damaged. In addition, the United States also lost a destroyer, an oil tanker and more than 60 aircraft. Most of the engineers on the USS Lexington were rescued. Japan lost an aircraft carrier, several cruisers and destroyers in five days of fighting. More importantly, however, the battle was the first major setback for Japan since Pearl Harbor. The actions of the United States showed that Japan is not invincible in the Pacific.
