Could HMS Hermes have been laid down early enough to enter service during the First World War?
Short answerA six-month advance would change little because trials dominated the schedule; the program would need to begin around late 1916 for wartime service to become plausible.
NotesConstruction itself was not the decisive delay. Moving the laying-down date by six months would also move launch earlier, but would not remove the long experimental period before commissioning. Britain used Hermes to test a new type of ship and had less reason to rush because other carriers were available. Only a much earlier 1916 decision, combined with wartime urgency, might plausibly have brought her into useful First World War service.
