Anti Aicraft ammunition

[V13dweller]

Is there anyway to get proper exploding anti aircraft ammunition like the ships use? I read through the Flak Vielings files in Goblin editor, and it has exploding ammunition, but the U-boats ones do not explode.
I even allocated my U-boats guns and even the deck gun with AA ammunition, but they do not explode in the sky, and why do Starshells not work when allocated to the Players U-boat deck gun?

I managed to give my sub Starshells that worked, but then , all ships, when they fired their AA rounds (Because I had to set it change the AA rounds to Starshells since the starshells do not present as an icon on the screen when in deck gun mode) they explode like starshells, causing huge lag due to every round being a starshell, does any one know the default AA round "Effect"?
And can you allocate specific ammunition to specific guns?
