designing the fortressess between Nordmark & Russia, though this will probably have to wait. The Coastal fortressess are outdated, and will have to be updated (though considering what the RL batteries south of Oslo did to Blucher I'm not so bad off)
Considering the geography of most major Norkarkian ports, there is little need for large costal artillery guns, as far as i know there is no ports that is open to the sea, narvik gothenburg is the one most exposed i can think of. It is usally at least 10km from the outlying islands to the main anchorage (the most extreme is stockholm were it is at least 30-40km)
So attempts to enter a harbour is best done with mines, historically (at least in the case of sweden) there were a lot of remotcontrolled mines laid in the main routes into the harbours, and ordinary mines in seconday passages.
But then again, counter bombardment guns are nice...
btw, is peopel aware that at its most shallow the sailing path in öresund is around 8m? Ships with more draft then around 7m have to use the belts.
