The Francesco Caracciolo class's turret-spacing trade-off

The large gaps between the Francesco Caracciolo class's superfiring turret groups gave the end turrets unusually broad arcs. Moving the inner turrets farther outward could have broadened their arcs too. Italian designers instead kept the groups relatively compact so armour could be concentrated around a shorter protected volume. Saving armour weight supported the ship's intended power-to-weight ratio and high speed. The design trades some idealized turret freedom against protection and propulsion rather than reflecting arbitrary placement. One visible feature can embody several linked naval-architecture decisions.
