The idea of my mod is to make world of SHIII more lively and historically accurate.
It adds a handfull of new ships and planes and rearranges original ones. It makes ships and planes that player meets during compaign , their outlook, and nationality, as well as ability to attack or repell enemy attack strongly historically accurate, altering day by day following their prototypes.

For detailed information and list of fixes look here.
