"After the war the Joint Army-Navy Assessment Committee reviewed the Japanese records and determined that SHINANO was the largest ship sunk by a submarine. The Japanese listed her as 69,000 tons, and the committee confirmed her at 69,000
tons."
Sounds like a typo combined with confusion. The original credit was 28,000 tons for a "Hayatake-class" carrier, as Enright claimed at the time. This was revised upwards to 71,000 tons at the end of the war, then JANAC's postwar analysis changed it downwards to 59,000 tons (not 69,000), a believable figure just under the standard displacement of the ship if she'd actually been completed. Makes sense.
69,000 tons is clearly too high, as it exceeds the standard displacement she would have had if she'd been completed. Of course, she wasn't.
Many websites, including the one on which we are posting, confirm the 59,000-ton figure. For example:
[uboat.net]
In any case, they did not use full load displacement to assess warship sinkings in those days.
You have a nice day, too.
