The Rohrbach Ro XI Rostra was a flying boat built in Germany in 1928 for use as a transatlantic mail plane. It shared the same general configuration its predecessor the Ro V Rocco: a conventional high-wing flying boat with cruciform empennage and two engines mounted tractor-fashion in nacelles mounted on struts above the wing. The flight deck and cabin were fully enclosed. However while the Rocco’s wings had been braced by struts the Rostra’s wings were a fully cantilever design.
