The class evolved directly from the R-class battleships, retaining structural features that later made added protection more feasible. In this analysis, their framing and conversion of weight into speed make them a more revealing transitional case than simply labeling Hood a fast battleship. Frames-per-meter and the structural support required by turrets, machinery, and armor reveal design choices that an external silhouette conceals. Looking inside the hull, rather than at the silhouette alone, is the key to this distinction.

The Renown class between battlecruiser and fast battleship
Renown and Repulse retained battleship-derived structure while trading a turret for speed, making them a useful bridge toward the fast-battleship idea.
