The series begins with British examples before widening its comparison to other navies. Examining omissions in the best-known body of naval history first provides a fair basis for criticizing another navy's historiography. The Japanese cases then show how labels such as destroyer, torpedo boat, sloop, and corvette can conceal considerable overlap in size, armament, and intended work. This framing prepares the viewer to compare practical capability rather than rely on category names alone.
