The RV Petrel has located the wreckage of the Japanese aircraft carrier Akagi, sunk in the Battle of Midway in June 1942. The ship is the second of two sunken Japanese carriers that the Petrel has located two days apart. They had previously located the carrier Kaga. The Akagi and the Kaga were two of four large carriers sunk in the battle, which was considered a turning point in the Pacific conflict in WWII.  Both carriers had participated in the attack on Pearl Harbor on December 7, 1941.   

The Akagi was found in the Papahanaumokuakea Marine National Monument, sitting upright in a debris field, in nearly 18,000 feet of water, or almost 3 nautical miles deep, more than 1,300 miles northwest of Pearl Harbor.
