The USS Horne t was sunk during the Battle of the Santa Cruz Islands with Japan on October 26, 1942, when around 140 of her 2,200 sailors and crew were killed. It lay lost on the seabed until it was discovered more than 17,000 feet (5,000 meters) below the ocean's surface in January.
The discovery was announced by Vulcan Inc. , which owns the R/V Petrel research vessel that discovered the Hornet. Vulcan was founded by the late Paul Allen , a co-founder of Microsoft.
Robert Kraft, director of subsea operations for Vulcan, said that they had set out to find the Hornet in honor of Allen: "Paul Allen was particularly interested in aircraft carriers so this was a discovery that honors his memory."
He said: "We had theHornet on our list of WWII warships that we wanted to locate because of its place in history as a capitol carrier that saw many pivotal moments in naval battles."
The Hornet was commissioned in October 1941, launched the Doolittle Raid on Tokyo, and played a key role in the US victory in the Battle of Midway with Japan in 1942, sinking four Japanese aircraft carriers.
But the Battle of the Santa Cruz Islands just one year after it was commissioned was its last fight. On the first day of the battle, it was hit by four bombs and two torpedoes in 10 minutes, leaving it dead in the water as some crew members were transferred to another ship and others tried to repair the damage.
It was attacked again with a torpedo and two bombs. It sank the next morning, and its crew had to abandon it.
Richard Nowatzki, a gunner on the ship, who survived the battle, told CBS News: "When they left, we were dead in the water."
"They used armor-piercing bombs, now when they come down, you hear 'em going through the decks ... plink, plink, plink, plink ... and then when they explode the whole ship shakes."
A 10-person crew on the 250-foot R/V Petrel found the wreck by using data from national and naval archives. The Hornet was found on the Petrel's first mission by its autonomous underwater vehicle.
This isn't the Petrel's first discovery of WWII wreckage. It discovered the wreck of the USS Indianapolis, a WWII heavy cruiser that played a critical role in the atomic bombing of Hiroshima, in August 2017. And it found the USS Lexington, which sank during the Battle of the Coral Sea in 1942, in March 2018.
