USS Lexington

[imntxs554]

I seem to recall hearing that either no Essex class carriers have ever been lost to enemy action or just a single one during WW2?

Your Correct the The USS Lexington CV-2 was damaged beyong repair by the Japanese in the Battle of the Coral Sea then it was Scuttled by US Battleships. The USS Lexington CV -16 was built to be a Essex Class and was in the Battle of Midway.
