This "design" apparently did exist as a specification for the Maru 6 program -- but since the plan was pretty much shelved with the defeat at Midway, nothing came of it. Assumedly, most (if not all) records of its existence were destroyed. Certainly, no official drawings survived (if they ever...

Something about Super-A Cruisers before Maru-5 Project. Source: 早川幸夫，スーパー・クルーザー「超甲巡」覇王伝説，月刊《丸》，2013年5月号 (Monthly "Maru", May 2013). The author stated that in a 1934 document named "Required National Defense Force from Treaty-Break to 1940" (条約決裂後ノ昭和十五年度ニオケル国防所要兵力表), that IJN's original plan...

Here I gathered all the various cruiser designs and projects proposed for the Imperial Japanese Navy Protected Cruisers: Not found any so far except the cancelled sister ships of the Unebi and Tone classes Light Cruisers: Design C-19 (1912) - A primary mine-layer cruiser design offered before...

Time frame should cover gearing-up to the Pacific war and the war itself. What should've they specified differently for industry to make vs. what was made historically, in order to put up a better fight against the 'West', or mostly against the USN/USMC/USAAF? Not to make a host of designs that...

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.

Hi Aichi F1A. Competitor of Mitsubishi F1M. There was a sea plane version and a land base plane version of F1A.
