Question

Should Japan build the I-400 class?

Short answer

Yes; he would prioritize Japanese submarines generally and especially long-range boats such as the I-400s.

Notes

Japan's geography and Pacific distances made long-range submarines particularly valuable. The answer to the I-400 construction question is an unequivocal yes. The class belongs inside a broader submarine program rather than being treated as a self-contained aircraft-carrying novelty. Japan should build the I-400s alongside as many other useful long-range submarines as industry could support.
