The Roland D.III prototype used a conventional cabane structure to further improve the pilot's view forward. This photograph was taken October 26, 1916 at the factory.This first prototype D.III was essentially the same as the earlier D.II except for the center section. Unfortunately, the maneuverability and handling qualities were not improved and few Roland D.III fighters served operationally. Production D.III fighters had a reduced-chord lower wing and larger fin. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |

The first Roland D.III protoype was powered by a 160 hp Mercedes D.III engine. The wings and tail were the same as the Roland D.II, but production D.III aircraft had a lower wing of reduced chord and a larger fin. Production D.IIIs were powered both by the 160 hp Mercedes D.III and by the 180 hp Argus As.III, apparently with the same type designation. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
The second Roland D.III prototype 700/17 (work #2500) photographed on May 16,1917 shows important changes from the first prototype.The engine is now a 180 hp Argus As.III and the fin is larger for improved directional stability. The chord of the lower wing has been reduced to further improve the pilot's downward field of view, resulting in the lower wing spars being closer together as indicated by the fact the interplane struts now are closer at the bottom instead of being parallel. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
The second Roland D.III prototype now carries an anemometer on the interplane strut to measure airspeed. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
Manfred von Richthofen flew the second Roland D.III prototype 700/17 on May 16, 1917 at Adlershof. While his evaluation is unknown, it must not have been negative or it seems unlikely that more Roland D.III fighters would have been ordered. In June 1917 Pfalz received an order for 100 Roland D.III(Pfal) fighters. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |

This Roland D.III powered by an Argus As.III engine was photographed on June 13, 1917 at Roland's Kaiserdamm facility. This aircraft was used to test different airfoils in an effort to improve flight performance. The D.III was the third configuration of the first Roland fighter generation, all part of a continued search for better visibility for the pilot. The D.I, D.II, and D.III all had a pair of synchronized machine guns mounted inside the fuselage for minimum drag, but these were difficult for the pilots to access in flight to clear jams, which occurred frequently. The fighters also shared the same structural technology and the 160 hp Mercedes D.III engine, although many D.II and D.III fighters used the 180 hp Argus As.III as the Mercedes was in great demand for many other aircraft types. Flight performance, maneuverability, and handling qualities for these very similar fighters were also nearly identical. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |

Bulgarian airmen in front of a Roland D.III of the Bulgarian air service. This aircraft has a 160 hp Mercedes D.III engine. At least six Roland D.III fighters were supplied to Bulgaria. Postwar one D.III, 3000/17, work number 2700, also powered by a Mercedes, was inspected by the British Armistice Commission. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |

Roland D.III fighters with their engines removed stored at Leignitz, today Legnica, Poland. Few Roland D.III fighters were built and fewer still saw combat; many, perhaps most, were sent directly to storage. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |

The structure of the second version of the Roland D.III prototype photographed April 20, 1917, after Roland had a production contract, showing its massive, robust center section. Wickelrumpf fuselage construction gave great strength without requiring a heavy internal structure. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
The structure of the second version of the Roland D.III prototype photographed April 20, 1917. The fin was larger than that of the D.II and first D.III prototype. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
Pilot's view from the cockpit of a Roland D.III illustrates the very robust cabane struts. The small wheel likely adjusted airflow through the offset airfoil radiator, allowing the pilot to control engine temperature. | J.Herris - Roland Aircraft of WWI /Centennial Perspective/ (9) |
