That's a Lexington class aircraft carrier. Only two were made, the Lexington and the Saratoga. Both of which saw extensive fighting in WWII in the pacific.
Both if which are now at the bottom of the sea. The Lexington due to the battle of the Coral Sea, and the Saratoga due to a Bikini Atol nuclear test(It took two of them to sink her).
That's not the most curious thing to me here, tho. The curious thing is the two ships were nearly identical aside from a black stripe at the top of the stack on Saratoga, so it would take someone with more skill than me to note which ship this is and when, as the stripe could have been removed or redone after the Lexington sank, or perhaps mostly only on one side of her, I dunno.
To me it appears to be an updated mid 1940's model in dock. Also note the 48 star US flag.
The Lexington was at the bottom of the sea by 1942. Saratoga was sunk in a nuclear test in 1946.
So this is quite an old photo.
