How 9.2-inch armoured cruisers could change classification

How would fast armoured cruisers with twelve 9.2-inch guns be employed and classified?

They would probably serve much like existing armoured cruisers but could be labelled dreadnought cruisers, leaving the faster Queen Mary generation to define the battlecruiser category.

The hypothetical ships would probably perform familiar armoured-cruiser missions. Their heavy twelve-gun battery and possible extra speed would nevertheless distinguish them from earlier classes. They might acquire the label dreadnought cruiser while Queen Mary and the later fast ships retained the battlecruiser name. That terminological split could matter at treaty time because legal categories often harden distinctions that began as design and service language.
