Rumpler 4B11

The Rumpler 4B11 was a floatplane based on the earlier Rumpler 4A13 landplane and unsuccessful 4B1 seaplane. Roughly eight of them were built and used during 1914 for patrol work.

Five were ordered in 1914 but one was not delivered. The rest arrived in August through December 1914. They served mostly at the Holtenau and Putzig bases.
