The Akagi, or 赤城 in Japanese, was regarded as the Japanese naval fleet's flagship at the time. The Battle of Midway, which took place close to the U.S. Hawaiian Islands, was won or lost as a result of the bombing of that ship and the subsequent sinking by American forces.
A dive was made by a group of deep-sea explorers and researchers using an autonomous underwater vehicle (AUV) with sonar. The long-lost Akagi aircraft carrier was later discovered, for the first time since it sank, at 18,000 feet of water in the Papahnaumokukea Marine National Monument (PMNM), some 1,300 miles (2,092 kilometers) northwest of Pearl Harbor.
Remote-operated vehicles (ROVs) were used by Nautilus researchers to descend to the seafloor in 2023, nearly four years later. It is the first time since its sinking in 1942 that people have actually seen the wreckage.
It was successful.
The study team, which included archaeologists from Japan and the U.S., carried out the historic, non-invasive dive in September 2023 to record the wreck's historical significance, assess its condition, and pay tribute to the victims lost on both sides of the conflict.
"As we are indeed on the carrier Akagi, let’s take a moment of silence, please, to remember the type of site that we are on – an important site – for great service and sacrifice and the loss of lives," mentioned James Delgado, an archaeologist associated with the expedition.
Surveying the Akagi and the other ships destroyed in the Battle of Midway has proven to be a difficult undertaking because to its distant location and exceptional depth. The Akagi marks one of the deepest, most remote cemeteries in the world with its dark, icy, high-pressure waters of the deep Pacific Ocean.
"We can understand this as Native Hawaiians and the depth and the reverence that we hold for this place, and for those who lay in the realm of Po Kanaloa, the god of the sea," said Malia Evans, a monument resource monitor at the O’ahu Education Coordinator PMNM. "We are in reverence as we view the Akagi."
Battle damage, including a section of the carrier's deck that had been turned upside down due to accumulated explosive pressure, was visible from the ROV cameras.
"The survival of this structure, even in its damaged state, is something we hadn’t been expecting. It’s rather amazing to see and even though it has deteriorated and fallen in, there are identifiable elements that clearly connect us back to that time and that point in the battle," said Delgado.
