Because of its smaller size in combination with a modified design, the aircraft is much more aerodynamic than the D.H.1 and therefore more manoeuvrable. Furthermore the D.H.2 was, in comparison to the D.H.1, equipped with a more powerful engine, which was a Gnôme Monosoupape rotary engine, with a power of 100 hp (75 kW).
The first flight took place on 1st July 1915.
At the beginning of the year 1916, the first of them were delivered to the Air Force. The pilots criticized that the DH-2 is difficult to fly, the reasons were the sensitive controls of the aircraft, but which made it, on the other hand an excellent dogfighter, that was able to compete with the Fokker-Eindecker in the air. However only experienced pilots were able to fly the DH-2.
