How turret layout changes the forward firing arc

As the British ships cross Bismarck's track, the game exposes an operational consequence of turret placement. The hypothetical design can bring its full main battery onto a forward target, while the historical Nelson arrangement restricts the aftermost turret in that arc. The historical arrangement concentrates protection and saves weight on a uniquely valuable pair. Armour concentration, turret geometry, and tactical firing arcs have to be considered together.
