The Royal Navy's cruiser numbers support a wider argument about the recurring burdens of pre-eminent power. Even in a multipolar system, the strongest state must spend resources to police distant interests and appear where decisions are made. Imperial Germany sought to challenge British power without making the same global investment. Possessing strength on paper is not enough if ships cannot be present at the relevant place and time. Economical cruisers such as the Mersey class helped turn national power into visible influence rather than commentary from the sidelines.
