USS Lexington (CV-2), nicknamed “Lady Lex”, was a Lexington-class early aircraft carrier built in the 1920s. She was the lead ship among two of her kind ever built. USS Lexington (CV-2) was sunk on 8th May 1942 by torpedoes and bombs from the Japanese Navy.
Lexington sustained first two torpedo hits. Soon afterwards, 19 Aichi D3A Japanese dive-bombers attacked Lexington. Though Lexington took down two aircraft, she was hit by two bombs. Within an hour, the leaking aviation fuel tank caused a massive explosion and two hours later another explosion occurred.
216 crewmen of Lexington were killed and 2,735 were rescued. And finally, American destroyer USS Phelps was ordered to fire 5 torpedoes to scuttle the critically damaged USS Lexington.
