Why paddle warships did not return after 1945

Were there paddle warships after World War II?

A few wartime survivors remained, but navies did not build a new postwar generation of paddle warships.

The wartime niche did not create a continuing postwar construction program. Some surviving vessels remained in use after 1945. Navies nevertheless treated them as inherited wartime craft rather than prototypes for a replacement class. Newer propulsion and purpose-built small ships displaced the need for new military paddle designs.
