What changes if the reconnaissance seaplane's radio works at Jutland?
Short answerJellicoe gains a clearer tactical picture, can press rather than turn away, and may inflict substantially heavier losses on the High Seas Fleet.
NotesReliable airborne reporting could reveal German turns and distinguish an actual torpedo attack from a theoretical threat. Jellicoe might then advance instead of opening the range, putting more British shells onto the High Seas Fleet during its withdrawal. Given the damage already inflicted historically, the added hits could sink German ships and turn Scheer's retreat into a costly fighting withdrawal.
