A sensible six-inch raider needed speed and range first

What would a sensible German six-inch cruiser for commerce raiding look like?

It would prioritize at least 30 knots and long range, with the planned M-class being the nearest German proposal to that requirement.

The mission matters more than the armament list. A raider must travel far enough to reach trade routes and remain fast enough to choose or escape engagements. The proposed M-class offered a plausible basis for that combination, although its eight six-inch guns left it weaker than a British Town-class cruiser in a direct fight. It was better suited to scouting and supporting commerce-raiding groups than to acting as a cruiser killer. Endurance and tactical freedom can matter more than headline firepower.
