LFG Roland D.XIV

The LFG Roland D.XIV was a German single‑engine fighter developed in the closing months of World War I by the Luft‑Fahrzeug‑Gesellschaft (LFG) in Braunschweig. Conceived as a successor to the earlier D.VII and D.XI types, the D.XIV first flew in early 1918 and featured a streamlined, fully enclosed wooden monocoque fuselage that reduced drag and improved pilot protection. Powered by a 185‑horsepower Mercedes D.IIIaü V‑12 engine, the aircraft drove a two‑blade propeller and achieved a top speed of approximately 210 km/h (130 mph). Its armament consisted of twin synchronized LMG 08/15 Spandau machine guns mounted above the nose. The D.XIV employed a cantilever wing design with slight stagger, eliminating the need for external bracing wires and further enhancing aerodynamic efficiency. Although only a handful of prototypes were completed before the Armistice halted production, the D.XIV demonstrated LFG’s innovative approach to structural integration and aerodynamic refinement. The aircraft’s monocoque construction influenced later interwar designs and foreshadowed the move toward all‑metal stressed‑skin fighters that dominated the 1930s. In post‑war evaluations the D.XIV was praised for its excellent climb rate and handling, prompting several foreign observers to study its construction techniques, which later appeared in the British and French experimental types of the early 1920s.
