The research vessel RV Petrel , almost one year after locating the remains of USS Lexington in the Coral Sea, has located the wreck of USS Hornet on February 12. The third of the three Yorktown -class aircraft carriers, Hornet was perhaps most famous as the launch ship for Doolittle's Raid on Tokyo. She also holds the distinction as being the last US fleet carrier to be sunk by enemy action (several light and escort carriers were sunk later in the war, including St. Lo and Gambier Bay at the Battle Off Samar).
Seeing combat at the Battle of Midway with her sisters Yorktown and Enterprise , Hornet later fought in the subsequent Guadalcanal campaign, helping to support landing, and safeguarding operations to reinforce the island with elements of the Seventh Marine Regiment alongside Wasp . Hornet fought alongside Enterprise at both the Battle of the Eastern Solomons in August, 1942, and her final stand at the Battle of Santa Cruz two months later that October. She sank in over 17,000 feet of water as a result of bomb and torpedo damage, and had been lost for 77 years. Her discovery leaves Wasp — sunk by Japanese submarine I-19 in September 1942 — as the only remaining American fleet carrier wreck unaccounted for, with Yorktown having previously been located by Robert Ballard in 1998.
The rediscovery of Hornet is just the latest of many such explorations undertaken by Petrel . In addition to Lexington in March, 2018, Petrel also relocated the wrecks of USS Juneau — made famous by the deaths of the five Sullivan Brothers — and USS Helena in that year. A previous expedition by Petrel in 2017 uncovered the wreckage of USS Ward , which fired the first American shots of World War II when she depth charged a Japanese mini sub prowling outside Pearl Harbor hours before the arrival of the air attack. Additionally, a week before Hornet's discovery Petrel located the Japanese battleship Hiei in the waters off the Solomon Islands.
In order to protect Hornet's remains, and because of her status as a war grave, the exact position of her final resting place is being kept secret.
