As I recall, capital ships had gun-directors (sort of like big range-finding binoculars) in the gun-director stations atop the masts. The forward gun-director fed azimuth and elevation to the forward turrets, the aft GD to the aft turrets. The individual turrets could also direct themselves, but the GD towers gave them better line-of-site (being high up on the masts). I would like to see the main gun batteries linked to two GD positions (forward to forward, aft to aft), which would control the main batteries remotely. The five-inchers I'd leave to local control (i.e. from within the turrets), since these are dual-purpose (AS and AA). This model would of course lay the ground work for battleships

. Next, I'd like to see surface-search radar (make this an arena option to have on or off). This would give approximate range to surface targets, but would not help with land targets. Finally, I'd like the option for different ammo types for all ship guns: HE, AP, Smoke, illumination (i.e. "star shells").
