Radio would transform age-of-sail command and control

What could the eighteenth-century Royal Navy do with Second World War-era radio?

It could coordinate dispersed scouting and battle forces directly, greatly improving information flow and an admiral's control over subordinate ships.

Age-of-sail fleets depended on sight, signals, and officers acting independently once separated. Reliable radio would allow inshore squadrons to report directly and let the main fleet remain beyond visual range while still responding. At battles such as the Glorious First of June, an admiral could also challenge a captain's misunderstood or disobedient maneuver immediately.
