Was there ever a Japanese jet transport or bomber designs conceptually in world war II?

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...

I've tried to collect the WW2 Japanese radar Type designation systems with data and if possible photos and drawings. Gathered from these sources: http://www.combinedfleet.com/radar.htm http://pwencycl.kgbudge.com/R/a/Radar.htm http://home.e01.itscom.net/ikasas/index.htm...

I wish to ask, if anybody knows what were the building capacity of the major shipyards of Japan in the 1900-1950 period, eg how long were the drydock facilities and building slips of these shipyards? Ishikawajima Shipyard Uraga Dockyards Kawasaki Dockyards Kure Naval Arsenal Maizurue Naval...

Hi. From the Research Topics - Designations Systems Forum part: Are there any further data/infos/pics in japanese service available on these IJN experimental aircraft? Yours tom! ;)

Not long ago I've finished drawing the various Amagi/Akagi carrier designs I've found in the Hiraga archive. So I post them here now: Amagi Aircraft Carrier Preliminary Design 1 https://www.deviantart.com/tzoli/art/Amagi-Aircraft-Carrier-Preliminary-Design-1-827366018 This is something...

Japanese Wikipedia entry on Akizuki class DD stated that IJN started in 1936 to study dedicated AA vessels following the example of Dido class. They contemplated anything from a 1000 ton torpedo boat armed with a single 10 cm or 12.7 cm AA gun to a quite large cruiser equipped with 12 double...

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.

Following a heavy reorganization of all Japanese aircraft topics, here is the breakdown of all Yokosuka-related threads this far: Yokosho (Yokosuka) Navy Type 10 Reconnaissance Seaplane Kusho (Yokosuka) Type 96 Carrier Attack (B4Y1) Yokosuka 9-Shi Medium-Sized Flying Boat (H5Y) Yokosuka 12-Shi...

Hi people I'm searching for data/drawings of never build Japanese carriers such as the G19 project Hopefully some one can help me on this subject

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...

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

Hi! Kawanishi E10K. It was the furst Kawanishi designed flying boat as 9-shi night reconnaissance seaplane. But not selected by the IJN. One prototype was converted into transport version as 94-shiki transport flying boat which had the gear for land transportation. Source:ENCYCLOPEDIA OF...

Does anyone have any info or pics or drawings of this airplane? I just discovered the existence of this plane while visiting Dave's Warbirds - http://www.daveswarbirds.com/Nippon/aircraft/Tillie.htm I did a google search and found no other info on this project except for a Czech site -...

...According to comments from someone on another forum, the Jap Zero's main weakness was that its fuel tanks were not "self-sealing", and that once hit they leaked profusely. Was this actually the case, and can anyone provide info on just exactly how the self-sealing tanks on Allied planes...
