All the information was gleaned from the relevant Wikipedia articles so de facto cannot be OR. Incidentally, the infobox for KGV-class gives a maximum armour belt thickness of 14.7in but the text gives 15in. I am aware that the above table needs conversions to metric measurements and links, but it is here as a point for discussion. Also, if the table were to be extended to also give displacement, speed and main armament it would be an invaluable resource for many WWII battleship-related articles.
