The Arethusas' legacy in later British cruisers

The Arethusas still looked like cruisers of their own era, with mixed six- and four-inch batteries rather than the twin six-inch turrets familiar from later British ships. Their link to later cruisers rests on what the Royal Navy asked them to do rather than on a direct match in weapons or silhouette. They scouted, led destroyers, screened fleets, adapted to new threats, and carried information between tactical forces and commanders. Their performance and missions became a starting point for later Royal Navy light-cruiser practice. This conclusion connects the class's First World War service to the cruisers Britain used in the Second World War.
