Did the Royal Navy expect its older World War I destroyers to remain in service far into the postwar period?
Short answerNo. They were expected to bridge the early postwar years and then be replaced around the end of the 1920s.
NotesThe Royal Navy expected the older destroyer classes to serve for a while after World War I. It nevertheless anticipated replacing them by about the end of the 1920s. They were therefore expected to bridge the early postwar years, rather than remain in service indefinitely.
