It first flew before the start of the war in August 1914 and was still in service as a trainer in 1918.

==Development== DFW designed the B.I as an unarmed, two-seat observation [[biplane]] for the Imperial Air Service in 1914, with its [[fuselage]] built from steel tubing and [[Biplane#Bays|three-bay wing]] from wire-braced wood, both covered in [[Aircraft dope|doped]] fabric. The aircraft had a distinctive appearance that differentiated it from its contemporaries as the [[leading edge]] of its wings curved to the junction with the trailing edge. Its shape was inspired by that of the earlier [[Rumpler Taube]] [[monoplane]], and led to the DFW aircraft being named the "Flying Banana" ({{lang|de|Fliegende Banane}}) by its pilots. The observer's cockpit was located beneath the upper wing while the pilot's was behind the wing's trailing edge. The aircraft flew a variety of [[water-cooled]] engines, although the {{convert|100|hp|lk=on|adj=on|sp=us}} [[Mercedes D.I]] [[straight-six engine|straight-six]] engine was commonly used. Some B.Is were fitted with the more powerful [[Mercedes D.II]] or [[Benz Bz.III]] engines. Its [[Radiator (engine cooling)|radiators]] were located on the sides of the fuselage and its cylindrical fuel tank was positioned above the upper wing.<ref>Lamberton, p. 130</ref><ref name=Gray/><ref>Herris, p. 42</ref>

The '''B.II''' was similar but had a more conventionally shaped two-bay wing with a straight leading edge. It mostly served as a trainer through the end of the war.<ref>Herris, pp. 66–67</ref>
