Produced by Société Anonyme des Appareils d'Aviation Hanriot at Neuilly-Sur-Seine, Paris, as the 75th of 79 HD.1s for the Belgian Military Aviation, the aircraft was delivered to the 1e Escadrille de Chasse, at the Les Moores (The Moors) near La Panne, Belgium, in September 1918. The 1e Escadrille was the well-known 'Thistle' squadron, among its pilots were the famous Willy Coppens, André de Meulemeester and Jan Olieslagers.

Till 1928 the aircraft was a front-line fighter, it was newly re-covered in 1930, and by 1933 it was deregulated to training duties. Withdrawn from service in 1934, it was sold in late 1934 to the Drossaert brothers of Brussels, André, Paul and Jules, indicated by the registration OO-APJ that was issued on January 8, 1935.
