Why is judging Graf Zeppelin by gun and armor totals inadequate?
Short answerBecause weapon quality, layout, firing arcs, radar, and weather exposure determine whether the nominal armament can actually be used.
NotesThe exchange warns against judging a warship by a spreadsheet of calibers and armor thicknesses. Radar, weapon quality, firing arcs, and the technical details of installation determine what those figures mean in combat. Graf Zeppelin's casemate weapons illustrate the problem: their placement and exposure could prevent their use in the same bad weather that grounded the air group. Operational access and arrangement are therefore as important as nominal armament.
