The Ki 67 was first flow in combat by the Army's 7th and 98th sentais and the Navy's 762nd kokutai in torpedo attack's during the air sea battle off Formosa in October 1944. The Ki 67 also operated in China and aganst the Marianas, and in defence of the Homeland.
I realise we will probably never get a Betty bomber, which would be approparate for the perioud,so the ki 67 is the only likely substute for a japanese bomber, but i wounder would u substute an A 26 for a B 26 or B25 if we did not have one? for a simmilar time perioud? The reasion I mention this is that in this time perioud you would be introducing and aircraft with late war speed and defensive aramement.
I have various sources for this info.
one of which is:
Japanese Aircraft of the Pacific War by Rene J. francillon.
That map looks like it would be great fun
Hopefully we will get some more Japanese aircraft in the future
