Update: IJN Taiho - Japan's armoured carrier

There isn't a lot of reliable, in-depth information about Japan's armoured carrier, Taiho, floating about in readily accessible publications. Even worse so than Britain's Illustrious class armoured carriers. But fortunately you can scratch about and find a few works which provide a comprehensive account. From these  I've assembled an overview of the doctrine, design and fate of this radical ship.

Fortunately, a comprehensive account can be found in the Polish/English Okretow Wojennych publication by Lars Ahlberg and Hans Lengerer – Taiho, Volumes 1 and 2. These documents go well beyond detailing Taiho's evolution and characteristics. They also spell out in fine detail the Japanese doctrines and practices that shaped her.
