It never had 2 rockets either … But its far more realistic then the Kikka or the Ho-Ri so yeah welcome to BR V Japan.
it only has 2 mounting points so it could carry two of those rockets, but not 6 mounting points
They are for bombs the rockets is the explosive bay theoretical payload that was build in very limited numbers just a prototype for testing. Even the in game model has place for 6 rockets since its literally based on the same rocket prototype.
The original one has no rocket modification at all:
it can carry only bombs.
N1K2-J could only carry 2x 60kg bombs or 2x Rockets in real life
N1K2-Ja had changes to vertical stabilizer and its ground attack capability was enhanced to carry 4x 60kg bombs or 2x 250kg bombs. Since it could mount 4x 60kg bombs, it should be able to mount 4x of those rockets.
BS it could carry no rockets in real life since it had no rocket modification it had only bomb variant all the rocket modifications are prototypes… bombs are not mounted like rockets by your logic P47 can carry 13 bombs… rockets are not installed like bombs … as always you waste my time…
Even the game model supports 6 rockets.
if it could have 6 then i dont oppose
