When Hitech releases patch25 that will fix the terrain editor, I will update it into my gunnery training terrain and verify the 16in gun's max range. I may have just placed the city strat for each country a mile or two past max range for land mode. My real hope is knowing the thing is loose in the MA, hunting it down all the time and putting it on the bottom will become a national past time.
But then I did put in permanent 2000ft base cloud banks over most of the water channels to give the task forces half a chance to go be naughty.
Half the terrain in the cloud editor. All cloud systems are duplicated across the three countries. Cloud fronts over water are permanent and from testing them, you need to be very close to the task group to see it through the random cloud openings.

Each country main island has a port at the top of the island as you see in this screen shot from the cloud editor. After testing for max range of the 16in gun, the task group for each of those three ports is where I will put the battleship. Guys wanting to slug it out between battleships would then know to stay in the primary water ring to hunt each other. The town will never stand a chance being pounded by the 16in batteries.
