Hehe, no, I'm not so ambitious.
I only want to know what ships from the ones aviable on the game could be used as 1991's ships.
i.e. I supose that I would not be very "realistic" to place a Seawolf.
It's hard to explain, but I just want... for example, I think that using a Perry would be non realistic, not because it didn't exist (was commisioned on 1976), but because in the game she has very powerfull sensors that I think :hmm: that would be too hard for an Akula I or a Kilo.
I don't know if I'm explaining well... sorry for my English
