Ok, yeah I understand now. I wasn't sure about Bobby.FoV is the bobys field of view, and because there can be other objects between the turret and the target I made a difference between those two.
If there is an enemy/target and the turret is able to rotate in such a way that it can shoot/look at it, it will. However, if there are other turrets or even the ship itself in between the turret and the target the turret will continue to shoot at it regardles of that entity.
So the AI still needs a lot of work.
