J2M - 30 mm Interceptor

[Myspit_mk]

I'm trying to find out any details for these. currently I received 2 photos which showed J2M might have a 4*30mm variant, but I can't find the resource.

As we know, J2M has tested different kinds of 30mm cannons, and there are multiple plans, such as 2*20mm+2*30mm or only 2*30mm(type 2 cannon), but till now it is pretty hard to find details, such as how many rounds for each gun. I have tried to search the whole internet but can't find more. The most likely source is a report from the U.S. military's postwar interrogation of officers at the Yokosuka base in Japan.

Does anyone know more about this?

Does anyone know more about this, Slope Game 2?

I’ve run into the same issue, most sources only confirm experimental fits but not finalized ammo loads. You might want to check US Technical Air Intelligence reports or postwar interrogation summaries from Yokosuka, they sometimes list armament details more clearly.
