I DID A MISTAKE
didnt notice the caliber has changed, I just looked at the version of the cannon
have noticed a strange fact about the A/J21RA/RB, they have both around 1kg of one second burst mass less than their prop versions, even when in game they got the same guns, but weirdly the ones on the jet variant are the same but with half the speed. Wikipedia says the jet versions also had the same guns (1 20mil akan m/45 and 4 12.7 akan m/39)
I am just wondering why it is like this, and maybe why did they have them like that irl if its historically accurate in the game?
