Naval technologies to prioritize in the 1930s

Which naval technologies should have received greater emphasis in the 1930s?

Deck-edge lifts, radar, and more dual-purpose gun development, especially 4.7-inch weapons, would be his main priorities.

Deck-edge lifts would be favored over centreline lifts where possible. Their armour and stability trade-offs are accepted because moving the lift can help increase a carrier's usable air group and flight-deck efficiency. Radar development would also receive greater emphasis. A dual-purpose 4.7-inch gun is another priority, accepting added weight and complexity in return for a weapon better able to meet both surface and high-angle air threats.
