Wreckage of Japanese Battleship Hiei Located

The Wreckage of Japanese Battleship Hiei was recently confirmed by the research vessel R/V Petrel, continuing its remarkable legacy of uncovering World War II-era shipwrecks. Despite the passing of Paul Allen, the co-founder of Microsoft who funded the research operation, the R/V Petrel remains dedicated to locating sunken relics of the past. The discovery of Hiei adds to a list of more than a dozen significant wrecks located by the Petrel team, shedding light on one of the most iconic warships of the Pacific Theater.

Launched in November 1912 and commissioned on August 4, 1914, the Japanese battleship Hiei was the second of four Kongo-class battlecruisers. Renowned for her formidable firepower and resilience, Hiei carried eight 14-inch guns and was protected by nine-inch-thick armor. During World War I, she patrolled Chinese waters and later took part in relief operations during the 1923 Great Kanto earthquake, earning her a place of significance in Japan’s naval history.

By 1929, Hiei was converted into a gunnery training ship, but as Japan expanded its fleet of aircraft carriers, Hiei was reclassified as a battleship. Her transformation marked a pivotal point in her service, preparing her for the fierce battles of World War II.

In November 1941, Hiei joined the fleet of six aircraft carriers that launched the infamous attack on Pearl Harbor, propelling the United States into World War II. Following the attack, she participated in the invasion of the Dutch East Indies and was later deployed to the Solomon Islands to support Japan’s push on Guadalcanal.

On November 13, 1942, Hiei encountered a fierce assault from American naval forces, including the destroyer USS Laffey (DD-459) and the cruiser USS San Francisco (CA-38). The intense barrage damaged her steering, leaving her vulnerable in the waters near Guadalcanal. For a full day, Hiei endured relentless air attacks by U.S. fighters and bombers. On the night of November 14, she finally succumbed to the onslaught, sinking with the loss of 188 officers and crew. Hiei became the first Japanese battleship sunk by the U.S. Navy during the War in the Pacific.

The wreckage of the Hiei was first identified by a Japanese research group, but the R/V Petrel was the first to deploy a remote-operated vehicle to thoroughly investigate and confirm the ship’s identity. Images captured by Petrel revealed two five-inch gun turrets resting in the depths of Ironbottom Sound—a stretch of water infamous for the numerous warships lost during the Solomon Islands campaign.

This discovery places Hiei among other historic World War II shipwrecks found by the R/V Petrel team, including the USS Ward (DD-139), USS Indianapolis (CA-35), and USS Lexington (CV-2). Ironbottom Sound now serves as a solemn underwater graveyard, preserving the memory of countless sailors who gave their lives during the brutal battles of the Pacific War.

The discovery of the Japanese battleship Hiei is more than just a historical achievement—it’s a tribute to the bravery and sacrifices made during World War II. Each sunken warship discovered by the R/V Petrel team tells a story of courage, strategy, and resilience.

As the R/V Petrel continues its mission, it honors the memory of Paul Allen, whose vision brought these hidden relics to light. For historians, veterans’ families, and enthusiasts, these discoveries offer an opportunity to connect with the past and preserve its lessons for future generations.

The wreckage of Hiei, now resting in the depths of Ironbottom Sound, is a haunting reminder of the cost of war and the enduring stories left behind. The meticulous efforts of the R/V Petrel team ensure that these stories are not forgotten, offering a window into a pivotal chapter of history.
