For some time I have wondered why did RN ship designers do some rather controversial decisions, especially when it comes to placing turrets. First, they managed to get rid of wing turrets with Orions and midshipturrets with QE's and Tiger. And then, after having perfectly good arcs of fire with their ships, they choose midshipturrets with G3 and N3 designs and limited arc forward with third turret of Nelsons. I understand why they place that third turret there with Nelsons but why on earth midshipturrets with G3 and N3? No arc of fire directly aft and magazines in the middle of engineering spaces. Edit: making text more understandable.
