British yards had the necessary scale for an extremely large Japanese design but were occupied by First World War work in 1915. Japanese facilities had plans to expand toward the required capacity but could not yet simply produce the hypothetical ship at home. The United States, by contrast, is described as able to construct a matching design and likely to produce a more capable result than the game's version. The point connects ambitious paper designs to the yard size, industrial capacity, and wartime priorities required to make them real.

Shipyard capacity limits a 1915 Japanese design
The closing counterfactual returns to the practical question of which yards could build extremely large Japanese ships in 1915.
