What would Admiral Henderson change if later naval design books appeared on his desk when he became Third Sea Lord in 1934?
Short answerHe would likely revise the King George V, carrier, and Tribal designs while pushing an effective standardized dual-purpose gun.
NotesHenderson would probably use the information first on the King George V class, carrier design, and the Tribal-class destroyers. The largest common change would be an earlier drive toward a standardized dual-purpose gun suitable for destroyers. An archival Illustrious-class sketch with deck-edge lifts suggests another low-weight way to increase aircraft capacity. The foreknowledge changes several concrete design decisions across the fleet.
