Airco D.H. Aircraft of the First World War

The Airco D.H.1 was the first production aircraft designed by Geoffrey de Havilland after his appointment as Chief Designer for the Aircraft Manufacturing Co. Ltd in June 1914.

The Airco D.H.2 was the first purpose built fighter aircraft to enter British service, and played a major part in the defeat of the Fokker monoplanes and the end of the Fokker scourge.

The Airco D.H.3 was Geoffrey de Havilland's first twin engined aircraft and was designed as a day bomber with the range to hit German industry.

The Airco D.H.4 was the Royal Flying Corps' first purpose-built day bomber, filling a role that until then had been carried out by aircraft that had been designed for other duties.

The Airco D.H.5 was designed in 1916 as a replacement for Geoffrey de Havilland's earlier D.H.2 pusher aircraft, but it was outclassed by its British contemporaries and was most useful as a ground attack aircraft

The Airco D.H.6 was Geoffrey de Havilland's first training aircraft, and was a deliberately simple aircraft designed to be produced in large numbers in preparation for the massive expansion of the R.F.C. planned for 1917.

The Airco D.H.7 was a design for a single-seat single-engined tractor fighter, to be powered by a Rolls-Royce Falcon engine.

The Airco D.H.8 was a design for a pusher aircraft that would have been armed with the 1 ½ pounder Coventry Ordnance Works gun (the C.O.W. Gun)

The Airco D.H.9 was an unsuccessful single engined day bomber designed to replace the D.H.4 but that was let down by its original engine.

The Airco D.H.9A was a single-engined day bomber produced by matching the fuselage of the unsuccessful Airco D.H.9 with a 400hp Liberty 12 engine. The resulting aircraft was one of the most successful bombers of its period and remained in front line service with the RAF until 1931.

The Airco D.H.10 Amiens was a two-engined heavy bomber based on the earlier D.H.3, but that arrived too late to make any contribution to the fighting during the First World War.

The Airco D.H.11 Oxford was designed as a potential replacement for the D.H.10 twin-engined day bomber, but never progressed beyond the prototype stage.

The Airco D.H.12 was to have been a twin engined day bomber based on the D.H.11 Oxford

The Airco D.H.14 Okapi was a single-engined day bomber designed to replace de Havilland's earlier single engined bombers, but that never progressed beyond the prototype stage.

The Airco D.H.15 Gazelle was an experimental version of the D.H.9A, built as a flying test bed for a 500hp B.H.P. Atlantic twelve cylinder watercooled engine
