Numbers 404 and 405 were the sole two examples of a unique seaplane design produced for the flying service of the Imperial German Navy during the First World War. By 1917 the output of the major German seaplane manufacturers was taken up producing machines for front-line service. As a consequence the only machines available for training purposes were those that had been made obsolete or which had been damaged and rebuilt.
Made by Kaiserliche Werft Danzig.
