Some mysterious Japanese projects...

[Stargazer]

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 — program cancelled; prototype built?)
• 11-Shi Bomber Seaplane (unbuilt Mitsubishi and Nakajima proposals — program cancelled)
• 11-Shi Advanced Trainer Seaplane (unbuilt Mitsubishi contender of the K6K and K6W prototypes)
• 12-Shi Test Fighter (unbuilt Nakajima proposal — program cancelled)
• 13-Shi Three-Seat Twin-Engine Fighter Bomber (Mitsubishi proposal — program cancelled)
• 13-Shi Union(?) Fighter (unbuilt Mitsubishi proposal — program cancelled)
• 13-Shi Twin-Engine Land Fighter (unbuilt Mitsubishi contender of the J1N Gekko/"Irving")
• 13-Shi Attack (unbuilt Mitsubishi contender of the G5N Shinzan/"Liz")
• 20-Shi Armored Fighter (unbuilt Mitsubishi proposal — program cancelled)

Any ideas? Pics? Descriptions? Specs?

Err Mitsubishi Seaplane???
Mitusbishi not known for such plane designs except from the F1M Reikan / Pete Reconnaissance Seaplane

And Stargazer forget to put the sources.

The profile is from Japanese Aircraft 1910-1941. It shows the 6-Shi Nakajima Special Bomber. According to Mikesh and Abe, the 7-Shi Special Bomber was basically the same as the 6-shi but without the staggered wings. One built in 1933 but came up short and ended up deferred to the 8-Shi specification where it was redesigned again and failed yet again. It was designated the D2N1 during the 8-Shi competition. Methinks Nakajima should have not kept the same designers through all three revisions.

Wikipedia contributor Buster40004, doesn't list sources for his list of Japanese projects. But, I suspect that the Wiki 1-Shi listing originated with Robert Beechy.

Guys, I know these web pages well already, and they do not provide any new information regarding the projects I mentioned... but thanks anyway.

I will try and dig up the references for the aircraft projects I mentioned... they're in some old Japanese book I have somewhere.

Hi all,

Noticed this thread on japanese early aviation, I have to many japanse aircraft I am looking for info on!

I have two questions that I could not so far find answers to:

-Does anyone have more info on the ISHIKAWAJIMA T-3 ? there is a picture here in the thread in the beginning, but I am especially looking for more pictures and a 3view? I have found some remarks on the web, but not much... It was later owned by Asahi Shimbun (registratio J-BBCA, fleet number 53?). See some pictures here too:

-Does anyone have maybe a three view (and pictures are always welcome too!) of the Nakajima NAF-2? It seems two were built as prototypes and also taken over by Asahi Shimbun newspaper. Registrations of these were J-BAAC and J-BAAD when in civil use. Very little pictures seem to be available, never seen a three view either... Who has more?

Many thanks in advance!!!
