The Aircraft Manufacturing Company (Airco) D.H.9 was intended as a replacement for the successful D.H.4, but it was limited by a bad engine: the 230hp Siddeley Puma, which was based on the B.H.P. Galloway Adriadic. The engine left the D.H.9 with less horsepower than its predecessor and left it with a poor climb rate and shedding speed and altitude in maneuver. Even with its serious limitations, 3,890 DH9s were produced and it served with about 30 squadrons on the western front starting in February 1918. The true character of the DH9 was not revealed until it was re-engined with the 400hp Liberty V12 in the form of the DH9A.
The D.H.9 was used in Palestine, Macedonia, the Aegean and Mediterranean as well as the Western Front with the RAF, Belgium, and the US Naval Northern Bombing Group.
