These would be non-mobile emplacements of large anti-naval guns with fortifications (or alternately maybe the player needs to build the fortifications separately). Should have ability to hit land units in range but the primary purpose is to target naval convoys. Should have longer range that mobile field artillery and greater damage.
Besides being historical, this is needed in-game because the existing field artillery is not effective against naval targets.
And, these units could be built inland to form a sort of Maginot Line.
