HMS Lion and the battlecruiser's cruiser role

The battlecruiser was a large cruiser intended to outrun stronger opponents and overpower weaker ones. HMS Lion's eight 13.5-inch guns, amidships turret, dimensions, and long hull show how speed and firepower shaped the type. A comparison with Tiger's large-tube boilers introduces another disputed design choice. Lion's amidships turret draws criticism because its firing arcs and demands on internal space made it less useful than a superfiring after position. Older cruisers and battleships also show why a cruiser hull could be as long as, or longer than, a capital ship. Longer, narrower hulls generally favored speed, while shorter, fuller forms favored maneuverability and subdivision, so the hull proportions followed the ship's intended role.
