Imagine a sub simulation using these two subs.

I remember a documentary on these Submarines. The Sen Toku class were essentially aircraft carrier submarine that carried 3 Aichi M6A sea planes.

Only 3 were ever built but it showed the Japanese military were forward thinkers. The I class could carry enough fuel to circumnavigate the globe 1 and one half times.The U.S took possession of them after WW2 concluded to study them. The Soviet Union learned of them and demanded one or more be turned over to them . The U.S instead took the Subs and used them for gunnery practice, destroying them all.

Fantastic read and video.
