From Jeune Ecole shortcuts to flotilla defence

Jeune Ecole promised a cheap path to sea control through torpedo boats, torpedoes, rapid-firing guns, and explosive shells that would strip away an enemy battle fleet. Jackie Fisher's flotilla defence adapted those weapons to the main fleet and a wider force doctrine. The German submarine campaigns are interpreted here as applications of that broader flotilla strategy, with the World War I blockade judged closer to success than its World War II counterpart. Their effectiveness therefore does not by itself establish the case for relying on a single weapon. Crewed and uncrewed warships working in partnership provide a modern example of combining capabilities. The appropriate fleet balance depends on the period, the mission, and the technologies available.
