Fighting fleets and designing them require different admirals

The admiral who states operational requirements and the specialist who turns them into ships, systems, and institutions need different skills. Andrew Cunningham illustrates how an excellent fighting commander could struggle when interfering with the Third Sea Lord's design responsibilities. Reginald Henderson demonstrated technical and aviation leadership but died before his ability to command a wartime fleet could be tested. John Jellicoe appears as one of the rare officers able to span both domains, while John Fisher excelled at vision, procurement politics, and institutional change rather than wartime fleet command. Rozhestvensky belonged more naturally to the engineer-organizer category, yet he was also the only available Russian officer capable of organizing the distant expedition.
