Did the Austro-Hungarian Navy successfully implement a defensive Jeune École strategy in World War I?
Short answerNot in a pure form; its flotilla defence was backed by dreadnoughts rather than substituted for a battle fleet.
NotesA viewer asks whether the Austro-Hungarian Navy successfully applied Jeune École defensively during the First World War. That description is too pure. Austria-Hungary possessed dreadnoughts and, in this assessment, better capital ships than the contemporary French force being used for comparison. Its system was flotilla defence backed by battleships, rather than small craft replacing the battle fleet.
