Four naval decisions worth changing

If one historical figure could be permanently persuaded of one idea, who should be targeted and what naval consequence would follow?

The choices target command, capital-ship design, naval-air control, and torpedo testing, where one decision could reshape later operations.

One intervention would persuade Beatty in July 1914 to change his approach to command. Another targets Fisher and the prime minister during Dreadnought's development, proposing five superfiring triple turrets with 14-inch guns and a speed of 24 knots, then asking how that larger leap might affect the naval arms race. A naval-aviation proposal would convince Beatty to preserve naval control of the Fleet Air Arm, with the panel distinguishing the original 1918 decision from his later opportunity to change the arrangement. A further intervention would insist on extensive testing of the Mark 14 torpedo and Mark 6 exploder.
