What three design recommendations would be most useful to the Admiralty in 1912?
Short answerBuild 28-knot Queen Elizabeths with triple 15-inch/50 turrets, give the main battery roughly 40 degrees of elevation, and develop high-angle 4.7- or 5-inch guns against airships and aircraft.
NotesThe recommendations stay close enough to 1912 technology to be demonstrable rather than merely predicting later carrier warfare. Greater speed and twelve 15-inch guns would transform the Queen Elizabeth class, while higher elevation expands the main battery's reach. A high-angle medium-caliber weapon begins solving the future anti-aircraft problem before the First World War fixes fleet design around lower-angle guns.
