Though the FF.33 had given excellent service, a machine with more power was needed. The Friedrichshafen FF.39 was designed to fill that role, with a 200hp engine and larger wings.[1]

Only fourteen of the FF.39 seaplanes were built, because after the first batch the more promising Friedrichshafen FF.49c had emerged. It was a 1917 design with a gun only for the observer.[3] They were used for patrol and they carried a radio transmitter.[2] Most of the FF.39's service life was spent in patrols of the North Sea.[1]
