The Deutschland class used eight diesel engines on two shafts, with four engines geared to each shaft. A proposed third shaft and another four engines could raise output to an estimated 80,000-81,000 shaft horsepower. The extra machinery would probably require a longer hull, which could also provide more fuel capacity and internal space. Another three guns would move the enlarged design toward the suggested miniature Scharnhorst.

A third shaft could turn Deutschland into a stronger raider
An enlarged Deutschland design with another shaft and four more diesels could gain speed, fuel capacity, and room for more guns.
