The six-inch mount trained at 38 degrees per second and the three-inch mount at 60, creating enough momentum to make nearby obstructions a serious design problem. A fast mounting had to begin braking well before an obstruction, so limited arcs would have sacrificed much of its promised performance. Designers considered moving the bridge, swapping the forward six-inch and three-inch positions, and accepting blast exposure or extra topweight. Clearing structures also threatened scarce accommodation in an already crowded hull. The approved arrangement prioritized all-round arcs for both six-inch and waist three-inch mounts rather than preserving the older superstructure layout.

Fast automatic turrets reshaped the whole ship
Training rates of 38 and 60 degrees per second forced designers to clear arcs that slower conventional turrets could tolerate.
