Here is a bundle of the IJN Special Type submarine carrier I-401, her aircraft, and then some other variations. Iona (Arpeggio of Blue Steel) was a "Fleet of Fog" submarine, whose captain was Gunzou Ghihaya. I-400 (Arpeggio of Blue Steel) is also a "Fleet of Fog" submarine. She is identical to Iona, just with a magenta hull instead. They were made by xYoshii_ and myself.
