In most respects the D 6 was a conventional biplane fighter; its one distinguishing feature came from an attempt to improve the pilot's upward view, normally limited by the upper wing.

Though it served its immediate purpose, this feature required extra cabane strengthening and much increased the induced drag associated with vortices at wing tips, now six rather than four in number.

Each upper wing tip was supported over the fuselage by a N-form strut, one foot at mid-fuselage and the forward one higher.

It was flat sided and tapered strongly in plan behind the 145 hp (108 kW) Oberursel Ur.III eleven cylinder rotary engine which was completely cowled, driving a large spinner and two blade propeller.

The D 6 had a fixed single axle undercarriage, with mainwheels mounted on cross wire braced V-struts and a tailskid.
