How to judge Hood and Yamato in context

How should Hood and Yamato be assessed without repeating national propaganda?

Judge Hood in the context of her completion and Yamato as an impressive but strategically misused investment whose secrecy blunted deterrence.

Hood was formidable when completed, but she fought two decades later after the strategic and technical setting had changed. Yamato is admired as a warship while criticised as an industrial and strategic dead end. A super-battleship deters only when rivals know it exists and must plan around it. Concealing the class therefore surrendered much of the peacetime leverage that might have justified its extraordinary cost.
