I'm using the WWII blank ship log to improvise SDS for my Argentine Navy while I wait for the South American Navy Supplement. I would like to get it right and I realized when it came to rating a ship's belt and turret armor that I think know what's right. But, I don't actually know what's right.
Here is what I think is right and if I'm wrong, please by all means let me know so I can get it right.
Armor less than 2" = CS
Armor 2 to 3" = CL
Armor 4 to 5" = CA
Armor 6 to 7" = BD
Armor 8 to 9" = BC
Armor 10 to 11" = BB
Armor 12" = BA
I've no clue what BA+ plus is as the Iowas and the Yamatos are both rated BA+ even though they vary so much in thickness.
