Why did Germany plan twenty-two lightly armoured Spähkreuzer that looked too weak for cruiser combat or commerce raiding?
Short answerBecause the design makes more sense as a long-range destroyer than as a conventional scout cruiser.
NotesThe 1938 planning figure reached twenty-two ships. Their light armour and modest cruiser qualities make the number puzzling if they are judged as commerce-raiding cruisers. Treating the design as a large, long-range destroyer makes the emphasis on speed, scouting reach, and numbers more intelligible. The ships would still remain vulnerable in a cruiser fight. The label can obscure the operational concept the design was meant to serve.
