#OTD in 1942, the Battle of the Coral Sea began. This was the first at-sea battle in world history where opposing ships were not in visual range of one another and all damage to the ships was inflicted by aircraft. The battle also represented the first time since Pearl Harbor that the enemy advance in the Pacific was halted.
During the battle, on May 8, the aircraft carrier USS Lexington (CV-2) was sunk by the Japanese. Her wreckage was lost until an expedition crew of Research Vessel RV Petrel discovered her in March 2018, seen below.
