Do Tiger, Renown, and the Admiral class represent one evolutionary battlecruiser lineage?
Short answerThey share a broad design tradition, but Renown's wartime improvisation and the Admiral class's extensive revisions make a simple Tiger-to-Renown-to-Hood progression misleading.
NotesRenown and Repulse were improvised from material available for battleship construction, with speed and rapid completion shaping what could be built. Their original six-inch belt contrasts with Tiger's nine-inch belt. The Admiral-class design also underwent substantial revision, including changes to subdivision and an increase from an originally contemplated six-inch belt to twelve inches. These ships still belong to the same broad design tree and philosophy. Their changing protection and purposes matter more than treating each successive class as an uncomplicated improvement on its predecessor.
