A nominal 28-knot Deutschland became easier to catch after prolonged operations reduced its practical performance. County-class cruisers could match these ships, a pair could trap them, and even Queen Elizabeth or Nelson-class battleships might catch them once their practical speed fell. Scharnhorst's roughly three-knot advantage appears small on a specification sheet but accumulates into substantial distance over hours of pursuit. Endurance keeps a raider at sea, while speed buys time before converging British forces can close the trap. That distinction helps explain why Scharnhorst posed a more demanding operational problem than the pocket battleships.

Why speed bought a surface raider time
The three-knot gap between a Deutschland and Scharnhorst changed how quickly a German raider could reach targets or escape as British forces closed the net.
