| A single-seat reconnaissance fighter derived from the
two-seat HD.3, the HD.9 was placed in the broad category
of Avions de Corps d'Armee (thus being the HD.9
Apl) and its armament consisted of a single synchronised
7.7mm Vickers machine gun. The airframe was
basically that of the HD.3 and the installation of the
260hp Salmson 9Z radial engine was identical, but fuel
capacity was considerably increased. The first example
of the HD.9 was completed in November 1918 as the
initial aircraft built against an order for 10 machines.
However, its career was cut short by the Armistice and
there is no evidence that all nine remaining aircraft
were completed.
