Here are some interpretation ...

    IJN post Taiho fleet carrier plans

    Taiho was ordered as part of Maru 4 fleet expansion program. She was a compromised design, mating an armored flight deck to a Shokaku size hull, resulting in lower freeboard an reduced hangar capacity. The first, prewar, draft of the subsequent Maru 5 plan included 3 more armored carriers of a...

    http://www.armouredcarriers.com/japanese-aircraft-carrier-taiho-armoured-flight-decks/ A nice look at the background of the Taihō-class program in general, along with an detailed overview of IJN Taihō herself. The fact that she doubled as a support carrier, for example, is often overlooked.

There seems to be a few variants mostly by how large the hanger should be and where to locate the conning tower and AA guns. Apart from the unique...
