Design and development

The FF.27 was a two-seat floatplane of mixed construction which had a single NAG 6-cyl 135hp piston engine mounted in the center nacelle. The tail empennage extended out from the fuselage via twin metal booms and the FF.27 had a pair of floats mounted under the center wing section.

The first flight of the FF.27 took place in 1914, occurring in response to the Baltic Ostsee-Wettbewerb 1914 aviation contest. After the outbreak of WWI, the FF.27 was delivered to the Imperial German Navy and given the serial 62, being used for reconnaissance duties.
