Would a Royal Navy air attack on the High Seas Fleet prevent Taranto or Pearl Harbor?
Short answerNo; it would make the danger visible, but later navies would believe improved defenses had answered it.
NotesTaranto and Pearl Harbor remain plausible even after a successful British carrier attack in World War I. Ten hits from a hundred aircraft could be dismissed as a disappointing success rate despite the damage inflicted. Later navies could point to radar and stronger anti-aircraft weapons as reasons that their situation was different. A precedent would expose the danger without necessarily overcoming confidence in newer defences.
