hopes your too tests could be successfull !! it will be really something (in my mind) really interreting, and as gap said, with unique ships features (as you can put unique ship for any class and add names boats for each of them), it would be possible to know which ships has been sunked, and even how many tonnage has been sank by axis for a given month, year).
It would give a lot of immersion to the campaigns.
Anyway, thanks to you to have a look about this
@gap
yes, a very good idea in case it takes too much consuming cpu time.
