As I understand, there is no San-Shiki?
I have changed main BB/CA guns into DP, and it seems to have small impact, probably enough, to be quite historical (lots of wasted ammo for maybe 1-2 extra planes shot down). Does changing from pure-Naval, into DP have any effect on surface combat? I see some guns, which are pure NAVAL, but still have ceiling. So, does gun shot at planes, when it have ceiling, or is it need to be set to AA/DP type?
However, this change brings a question:
Should not shrapnel ammunition, also increase ground bombardment effects?
There are few types of 12.7 cm/50 Type 3 naval gun. As I understand, only those with maximum elevation of 75 deg can be used as DP, which brings another question:
What was actual ammunition type used for anti-aircraft fire? Was it not a San-Shiki?
I am guessing T A means Twin A type, and S A means Single A type, as I see Single A was used at Hatsuharu class, but in game it uses only T B, not that it changes anything, because all guns have the same statistics, which bring another question:
Should not different maximum elevation, also change maximum range/ceiling?
And, since ammunition is THE SAME, should not all 12.7 cm guns be DP? With probably worse ceiling/accuracy for those, with lower maximum elevation? Why 12.7 AA type have WORSE accuracy, than standard DP? Is accuracy used in determining hit of planes?
Was not the special-fragmentation-ammunition, used several times at Guadalcanal, a San-Shiki? Does Kongo used it in main guns?
Ok, I found this:
APC Type 91 - 1,485 lbs. (673.5 kg)
Common Type 0 HE - 1,378 lbs. (625 kg)
Common Type 3 IS - 1,371 lbs. (622 kg)
So, there is San-Shiki for 14', and I do not see any special shrapnel ammunition type, besides San-Shiki.
