Protected by heavy air bomb proof horizontal armour. The funnel was also protected against bombs and was at the same time foundation for the catapult with a hangar below the stack to store the scout plane.

Notes
1. He was an industrial and marine working as illustrator and writers for newspapers but also for the United States Lines and other shipbuilding related industry. In the 1950s he made promotional maps and brochures to celebrate the passenger ship ss United States which won the Blue Riband in 1932.
2. The Yamato-class possessed 3x3-46cm/18.1” guns, so slightly larger calibre but less in number with 9 against 15 guns. The normal displacement of 65,027 tons was comparable. The never realized American Montana-class with a displacement of 64,240 tons was to be fitted out with12-40,6cm/16” 50 cal Mk 7 guns. The never realized British Lion-class with a standard displacement of 41,200 tons was to be armed with 3x3-40,6cm/16” guns while HMS Vanguard with a standard displacement of 45,200 tons was even armed with a smaller calibre namely 4x2-38,1cm/15” guns. In the French and Italian was the calibre of the main guns also 40,6cm/16”guns. The Russian navy choose for 40,6cm/16”, her Sovetsky Soyuz-class (project 23) was comparable with the Japanese Yamato-class dealing with the dimensions but weaker armed. Project II-2p was to be armed with 1x2-45,7cm and 1x4-22cm. The German battleships Bismarck and Tirpitz were armed with 4x2-38cm/15” guns, so far weaker than the Yamato. However the (theoretical) H-44 design with a displacement of 131,000 tons was to be armed with 50.8cm/20: guns.
