WW2 1940's tech questions

[LoneWolf_gabo]

Hello everybody,

As part of the development of my sim i need to get some info regarding the functionality of some tech of 1940's. While most topics can be researched on the web there are some stuff that remains unknown to me.
And i think this forum is the best resource for the matter.

One key topic i have been trying to get right is how big deck guns of for example a destroyer or a cruiser work for the aiming. I understand there's a "turret" called the fire director where inside it there's crew tracking and providing data for the firing solution. Not sure wich data other than range finding and target tracking maybe?
Also, does guns automatically track where the director is aiming? or was this done manually inside each gun turret? if so, did the fire director transmit via radio the range and direction to shoot?

The main reason for needing to know this is that crew will have to be trained to speed up and improve the function they do. So i need to know what rely on crew on what rely on automatization.

Hope it's not too much to ask
