A Third Sea Lord counterfactual focuses on prewar materiel

Which Sea Lord post and period would offer the best opportunity to improve Royal Navy readiness?

He would choose Third Sea Lord before the Second World War, avoid obstructing Henderson, push readiness, prefer 15-inch guns for the King George V class, and order more carriers and Tribals.

The personal counterfactual chooses the prewar period and the Third Sea Lord's materiel responsibilities. It avoids displacing Henderson and instead replaces Chatfield. The proposed changes include avoiding the 14-inch gun decision on the King George V class and improving logistics. More carriers, Tribals, and related ships would also be ordered before war began.
