I just wonder if it only has 2 type 5 guns with 84 rounds, which means you must be very careful to aim, consider there are a lots of sparks in 30mm ammunition, J2M5 's performance is even worse than the J2M2, I remembered someone mentioned that J2M5 has additional 20mm guns, but unfortunately it is still not fixed, should J2M5 move to 4.7?
Yes it had IRL 2 30mm + 2 20mm. Here is doc and even video footage of this plane standing on the field
To be honest ammo capacity is also wrong. It has 42 rounds but this number of ammo was taken from 30mm Type 2 which was fitted with drums while J2M5 has Type 5 guns which was fitted with belt so there mostly was another number of ammo but unfortunately correct number is unknown at the moment
I think as minimum it had 50 rounds like Kikka and J8M1 with the same ammo has but it is only my thinks
I have checked some documents, but unfortunately, most of them havenβt even mentioned that this Prototype exists. but if it could have like 50 or 60 rounds per gun(like J7W1), then will be perfect, I am not sure if Gaijin wants to fix it, even the additional 20mm guns report has been submitted over 2 years( which was approved)
