imperial japanese navy

I've recently found this pretty interesting Japanese Project at the Hiraga Archive. It looks like a hybrid cruiser-carrier warship from 1920's era. 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...

I've found calculations for a 10.000ton cruiser in the Hiraga archives. What is unique about this vessel that it would carry 4 triple 20cm heavily armoured gun turrets, though calculations shows quad turrets were considered as well, but it is unknown if it would carry the same number of such...

I've posted this on another forum but it is better to post many forums to see if anybody know anything about this, I've got hold an extract from a naval forum about possible modernisation plans for the Kawachi class Battleship IJN Settsu which was stripped from her armament after the Washington...

Anyone know something about japanese airships until 1945 ? I have found this article on j-aircraft : http://www.j-aircraft.com/research/jas_jottings/japanese_airships.htm

Built by Osaka Imperial University and Syowa Kookuu-keiki Co.Ltd., likely on a Imperial Japanese Navy contract. Note that postwar the Japanese use the American spelling for analyser, i.e. analyzer. There are a couple of pictures at the original article. It had an older (completed in 1942)...

In 1932, the Imperial Japanese Navy issued a specification for its 7-Shi Land-based Attack. The only known contender (and winner) of that competition was the Hiro G2H1, or Type 95 Land-based Medium Attack, Twin Engine, also commonly known as the "Dai-ko" or "Big Attack." It was a remarkably...

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

Hi! Kawanishi E13K. http://www.airwar.ru/enc/sww2/e13k.html Auto translation. In 1937, the Imperial Japanese Navy decided to change the old Scout Kawanishi E7K seaplanes (Navy Type 94 Reconnaissance Seaplane) to more advanced aircraft. For this purpose, contracts were signed with companies...

Hi! Aichi E16A1 Zuiun.

I thought we already had a thread on these, but I must have been wrong. http://ajw.asahi.com/article/behind_news/social_affairs/AJ201404060014 IMAGE CREDIT: THE ASAHI SHIMBUN

While going through some Japanese sources I came across these seemingly undocumented projects: 7-Shi Special Bomber (one Nakajima prototype built — program cancelled) 7-Shi Reconnaissance Seaplane [E7N] (unbuilt Nakajima contender of the E7K "Alf" and E7A) 8-Shi Fighter (Nakajima proposal —...

Hi all! Maybe somebody can help with better, or at least bigger, drawing of this triplane monster? The only one which I could find is this (see attachment). I found it here: http://www.straggleresearch.com/2010/10/navy-type-10-carrier-torpedo-aircraft.html.

Reading the chapter about the Aichi M6A1 Seiran/I-400 submarine in "Strike From Beneath The Sea" by Terry C. Treadwell, I wondered, why this aircraft actually were fitted with floats ? In the mentioned book and in other sources, too, it's said, that they should be catapulted from the submarine...
