The Rohrbach Ro X Romar links constrained German aviation work with French demand for maritime reconnaissance. Although one aircraft served with Lufthansa, most operated for the French Navy. Its engines sit above the wing with pusher propellers, a layout that some design bureaux believed improved takeoff from water. The Do X provides the contrast with its paired tractor-and-pusher installation. Designers were trading possible takeoff and water-clearance advantages against the complexity of multiple engines and propellers.

Rohrbach Ro X Romar and the pusher layout
The German-designed Rohrbach Ro X Romar, used mainly by the French Navy for reconnaissance, illustrates experimentation with above-wing pusher engines and complex propeller arrangements.
