Wreckage from the USS Lexington was discovered by the expedition crew of Research Vessel (R/V) Petrel on March 4. The Lexington was found 3,000 meters (about two miles) below the surface, resting on the floor of the Coral Sea more than 500 miles off the eastern coast of Australia.

The USS Lexington was originally commissioned as a battlecruiser but was launched as an aircraft carrier in 1925. She took part in the Battle of the Coral Sea (May 4-8, 1942) along with the USS Yorktown against three Japanese carriers. This was the first carrier versus carrier battle in history and was the first time Japanese forces suffered a permanent setback in its advances on New Guinea and Australia. However, the U.S. lost the Lexington and 216 of its distinguished crew.
