The conclusion distinguishes a design's technical plausibility from the pace at which a navy can finance and complete it. Amagi and Kii are judged workable, although Kii would probably demand more time and effort than planned. The larger Number 13 class would strain resources, while its 18-inch gun programme was still immature, so only part of the class might enter service by 1930. Economics, construction capacity, and weapon development therefore matter as much as paper design feasibility.

What Japan could likely have completed
Amagi and Kii are judged feasible, while the Number 13 programme would probably advance more slowly because of cost, construction pace, and immature 18-inch gun development.
