The book's closing reflection defines its subject as three generations of ships and three generations of crews. Moving from the Tribals through the Battles to the Darings means following changing wartime experience, service expectations, and the people who operated each design. An author must choose both the subject and the chronological boundary of a class history. Keeping the narrative largely out of the later 1950s prevents the book from becoming a separate study of missile-age refits and replacement programs. This passage makes the human and editorial structure of the book explicit.
