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.

“To pay tribute to the USS Lexington and the brave men that served on her is an honor,” said Paul Allen. “As Americans, all of us owe a debt of gratitude to everyone who served and who continue to serve our country for their courage, persistence and sacrifice.”

As one of the first U.S. aircraft carriers ever built, the Lexington became known as “Lady Lex” and went down with 35 aircraft on board.

Lexington was on our priority list because she was one of the capital ships that was lost during WWII,” said Robert Kraft, director of subsea operations for Allen. “Based on geography, time of year and other factors, I work with Paul Allen to determine what missions to pursue. We’ve been planning to locate the Lexington for about six months and it came together nicely.”

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.

The Lexington had been hit by multiple torpedoes and bombs on May 8 but it was a secondary explosion causing uncontrolled fires that finally warranted the call to abandon ship. The USS Phelps delivered the final torpedoes that sank the crippled Lady Lex, the first American aircraft carrier casualty in history. making it the first American aircraft carrier casualty in history. With other U.S. ships standing by, 2,770 crewmen and officers were rescued, including the captain and his dog Wags, the ships ever-present mascot.

During the Battle of the Coral Sea the Japanese navy sank USS Lexington (CV-2), USS Sims (DD-409), and USS Neosho (AO-23), and damaged the USS Yorktown. The Japanese lost one light carrier (Shōhō) and suffered significant damage to a fleet carrier (Shōkaku).

“As the son of a survivor of the USS Lexington, I offer my congratulations to Paul Allen and the expedition crew of Research Vessel (R/V) Petrel for locating the “Lady Lex,” sunk nearly 76 years ago at the Battle of Coral Sea,” said Navy Adm. Harry B. Harris Jr., head of the U.S. Pacific Command. “We honor the valor and sacrifice of the “Lady Lex’s” Sailors — all those Americans who fought in World War II — by continuing to secure the freedoms they won for all of us.”

The Battle of the Coral Sea was notable not only for stopping a Japanese advance but because it was the first naval engagement in history where opposing ships never came within sight of each other. This battle ushered in a new form of naval warfare via carrier-based airplanes. One month later, the U.S. Navy surprised Japanese forces at the Battle of Midway, and turned the tide of the war in the Pacific for good.

Based on some initial success with his M/Y Octopus, Allen acquired and retrofitted the 250-foot R/V Petrel with state-of-the-art subsea equipment capable of diving to 6,000 meters (or three and a half miles). Since its deployment in early 2017, the ship was active in several missions in the Philippine Sea before its transition to the Coral Sea off the Australian Coast.

Allen-led expeditions have also resulted in the discovery of the USS Indianapolis (August 2017), USS Ward (November 2017), USS Astoria (February 2015), Japanese battleship Musashi (March 2015) and the Italian WWII destroyer Artigliere (March 2017). His team was also responsible for presentation to the British Navy in honor of its heroic service. Allen’s expedition team was permanently transferred to the newly acquired and retrofitted R/V Petrel in 2016 with a specific mission around research, exploration and survey of historic warships and other important artifacts.
