The Royal Navy used sloops and light cruisers for routine presence, then relied on a station flagship to deliver a more serious warning when a dispute escalated. That ship showed that a local squadron, and ultimately a battle squadron from the home or Mediterranean fleet, could follow if the warning was ignored. Armored cruisers also reinforced fleets and protected important convoys in wartime, so the role demanded both capability and numbers. A larger battlecruiser could outgrow a station's yards and ports or make its arrival a stronger threat than the dispute required. As HMS Tiger-type battlecruisers became second-rate capital assets and older cruisers approached retirement, a cheaper 9.2-inch cruiser could restore the missing third-rate mass.

Station flagships made naval deterrence scalable
Armored cruisers supplied an intermediate rung between routine flag-showing patrols and the arrival of a battle squadron, but later battlecruisers became too scarce and expensive for that work.
