A balanced surface fleet for Poland

What mix of surface combatants would make sense for the Polish Navy?

Combine smaller Baltic-focused corvettes with two or three larger frigates for expeditionary work.

A mixed fleet would avoid asking one design to perform incompatible missions. Corvette-sized ships derived from the Orkan or Visby idea could serve local Baltic tasks, while two or three larger frigates would provide the endurance needed for expeditionary operations.
