Why modern warships prioritise sustained speed over maximum speed

Modern ships are often slower on paper because designers value efficient operational cruising speed more than a high maximum that cannot outrun aircraft or missiles.

Question

Why can many Second World War ships outrun modern warships?

Short answer

Modern designs trade maximum speed for efficient sustained operation because a surface ship cannot outrun aircraft or missiles anyway.

Notes

Modern surface ships are not built for the same top speeds as many Second World War designs. Aircraft and missiles cannot be escaped through a few extra knots, weakening the old tactical case for extreme maximum speed. Designers instead emphasise the speed a ship can sustain while covering distance and remaining useful with the fleet. The distinction is between a spectacular trial figure and the operational pace that endurance, machinery, and mission actually demand.
