The Rumpler G.I was a bomber aircraft produced in Germany during World War I, together with refined versions known as the G.II and G.III.^[1]

Design and development[edit]

Based on a prototype with the factory designation 4A15, the G.I and its successors were built to a conventional bomber design for their time, two-bay biplanes with unstaggered wings of unequal span.^[2] The pilot sat in an open cockpit just forward of the wings, and open positions were provided in the nose and amidships for a gunner and observer. The engines were mounted pusher-fashion in nacelles atop the lower wings and enclosed in streamlined cowlings.^[2] Fixed tricycle undercarriage was fitted, with dual wheels on each unit.^[2]

The G.II version was almost identical, but featured more powerful engines and carried a second 7.92 mm (.312 in) machine gun and increased bombload.^[2] The G.III was again similar, but had engine nacelles that were now mounted on short struts clear of the lower wing.^[2]
