Deutschland-class raiders and ammunition performance

The Deutschland-class design receives a mixed assessment: its range suited commerce raiding, but the ships did not fully answer what the Kriegsmarine required. Graf Spee sometimes expended main, secondary, and torpedo ammunition against merchant targets, imposing an unexpectedly high cost on each sinking. Long periods at sea may have affected how well shells were stored and how reliably they performed, though this remains a suspicion. Despite the German Panzerschiff label, the ships fit the surface-raider or heavy-cruiser categories better than the battleship category. The ammunition point needs further research and is not offered as a settled explanation of the Battle of the River Plate.
