I made a ship with one missile turret and one cannon turret last week. Tonight I finally took it out for testing against NPC pirates. When I activated the AI I found that the missiles were launching just fine, but the turret didn't rotate at all in order to lock onto targets. The cannon turret orientated itself as needed to fire at the same target.
(I also wasn't aware until this testing that AI can only be activated manually at present.) :/
