The DP.II was a development of the earlier DP.I with the change to be a cantilever unequal-span biplane.[1] The DP.II was built with wooden wings and a steel-frame fabric covered fuselage and tailplane.[1] The aircraft had a fixed tailskid landing gear and was powered by a Siemens-Halske radial engine.[1] Following the single Siemens-Halske Sh 4 powered prototype was a production run of 58 improved DP.IIa variants powered by Siemens-Halske Sh 5 radial engines.[2]
