The roles defined in the styles are the only ones the AI will choose from when building its ships; there is no way to add new roles that I'm aware of.

Well, here goes Eight Small_Tiny_Huge_Cargo seconds too late for the bad news!

Hello,

thanks for the answers. So that would mean i'm stuck to the 26 ships i can choose and replace via the "Create Custom Ship Style" button in "Appearance" in the AI Race Setup ? Or is it possible to add additional ships by adding something like this in the new saved shipstyle (blue are the original entries, red the newly added ones):

...
<AIAttacker1>AttackerTemplate2_t</AIAttacker1>
<AIAttacker2>AttackerTemplate1_t</AIAttacker2>
<AIAttacker3>AttackerTemplate3_t</AIAttacker3>
<AIAttacker4>AttackerTemplate4_t</AIAttacker4>
<AIAttacker5>AttackerTemplate5_t</AIAttacker5>
<AIBattleship1>BattleshipTemplate2_t</AIBattleship1>
<AIBattleship2>BattleshipTemplate1_t</AIBattleship2>
<AIBattleship3>BattleshipTemplate3_t</AIBattleship3>
<AIBattleship4>BattleshipTemplate4_t</AIBattleship4>
<AIBattleship5>BattleshipTemplate5_t</AIBattleship5>
...

What do you think - is this possible ?

AFAIC, Kryo's reply made it clear that (sadly) it can't be done... never hurts to 'try' just for fun, but i doubt the AI would use any or at least in the same fashion as what their pre-coded algorithms allow for.
