The 9.2-inch cruiser proposal addresses a specific German problem: the Deutschland class and its six 11-inch guns. In this counterfactual, the British ship brings twice as many slightly smaller weapons, greater speed, probably better armour, and technology developed beyond the First World War foundations of the German design. It could also expect friendly reinforcements, making interception especially dangerous for a lone surface raider. A credible counter can restrict an opponent's deployments before either ship fights.

How a 9.2-inch cruiser could constrain Deutschland-class raiders
The proposed British cruiser is assessed as a deterrent to Deutschland-class deployments because it combines twelve 9.2-inch guns with greater speed, protection, and likely support.
