The Japanese aircarft carrier IJN Kaga, part of the six-fleet carrier that launched planes that attacked Pearl Harbor in 1941, has been discovered by the crew of R/V Petrel.
Kaga, located 5,400 meters below the surface of the Central Pacific, was scuttled by the Japanese on June 4, 1942 during the Battle of Midway after being attacked by approximately 30 dive bombers and two torpedoes launched by the USS Nautilus.
The crew aboard R/V Petrel spent several weeks surveying the massive area, documenting more than 500 square nautical miles, all within the Papahanaumokuakea Marine National Monument.
