The British ship appears to hold its distance when it carries only the main battery. This suggests that secondary armament may cause the game's tactical system to seek a range where every weapon can engage. That behavior would squander the reach of a powerful main battery by bringing the ship into a less favorable tactical envelope. The test also reflects a real design tension: secondary guns remain important against small ships even when closing range is undesirable for the battleship's primary mission.

Secondary batteries can shape engagement range
The no-secondary trial suggests that fitting secondary guns may encourage a battleship to close instead of exploiting long-range firepower.
