• 
  I notice the standard designation system seems to completely break down with the last two interceptor competitions, a possible indication that we're missing later revised specifications/competitions within 17-Shi and 18-Shi?

I notice this doesn't seem to have a corresponding entry under the 14-Shi section, or indeed any later section.

Otsu does not equal "B," even though it is often translated into English as such.

About 13- Shi Attack Bomber : is really Mitsubishi submitted project of Mitsubishi G5M ?

Stargazer said:

My understanding is that it was submitted but not accepted.
However, I do not read Japanese, and I may therefore have made a mistake.
Some forum members here such as blackkite are much more competent to answer your question I think!
