The German ship's rapid 3.4-inch fire cannot penetrate the main belt, yet it repeatedly damages the British fire-control system. The low-level tower arrangement appears to be the vulnerable point, prompting a rebuild with a more advanced main tower and a compact secondary tower. Fitting the new structures requires increasing beam and reconsidering the placement of the extra main turret. Six-inch and three-inch weapons are also added because the simulated opponent persistently forces the action into secondary range.

Small-calibre hits expose the fire-control system
Repeated 3.4-inch hits damage fire control and prompt a wider redesign of towers, beam, and secondary armament.
