I remember reading a story about that in Reader's Digest when I was a kid. The captain was absolutely convinced that he had sunk a carrier, but the Navy didn't believe him at first because they didn't know this one existed.
Shinano was a death trap, and took over 1400 men with her to her watery grave.
To date, the wreck has never been found.
