The Rumpler B.I (factory designation 4A) was a military reconnaissance aircraft produced in Germany during World War I.[1]

Design and development

[edit]

The B.I was a conventional two-bay biplane with unstaggered wings of unequal span.[2] It featured two open cockpits in tandem and fixed, tailskid undercarriage.[2] Its upper wing reflected the wing design of the Etrich Taube that Rumpler was building at the time.[3]

Rumpler built 198 of these aircraft for the Luftstreitkräfte, plus 26 seaplane versions for the Imperial German Navy.[2]
