About the Battleship Mutsu

I was dissatisfied with the armor of the battleship Mutsu and submitted a bug report.


However, the management countered with materials from the Hiraga archive.

Normally, the Hiraga Archive is a reliable source of information, but there were some suspicious aspects to the materials presented by the management.

For example, the cover says 1924. The chimney on the drawing is bent. The main armor is listed as 480mm. The armor above the main armor is listed as 360mm.

I am very confused and don’t know what is right.

If you have any knowledge about the battleship Mutsu, please let me know what is correct.


That’s not “360 mm” but pounds (lbs.).
360 lbs. = 228.6 mm
