The third G3 turret is hemmed in by the superstructure and secondary battery, which limits its ability to engage targets ahead. The arrangement has sound engineering logic, but its combat value seems too low for the weight and cost. Concentrating two quadruple turrets forward, as in the French approach, at least gives every carried gun a clear tactical purpose. The comparison favours layouts that give each heavy turret a useful field of fire.

Why the G3's third turret troubles this design
The G3's amidships third turret illustrates the tension between compact engineering and a battleship's usable arcs of fire.
