List of de Havilland aircraft
This is a list of aircraft produced or proposed by Geoffrey de Havilland or designed at the de Havilland Aircraft Company from its founding in 1920 until its purchase by the Hawker Siddeley Group in 1959.
The aircraft are ordered by de Havilland model number; the numbers started with de Havilland's employment at the Airco company as chief designer. Although Airco built the planes, their design was owned by de Havilland and when de Havilland started his own company, he continued the numbering. The numbering sequence continued for later designs of de Havilland's aircraft company, even if they were designed by a factory team with little input from de Havilland himself. The DH.89, for example, was the 89th de Havilland design.
The designs DH.121 and DH.125 which were under development when de Havilland lost its separate identity under Hawker Siddeley, retained their numbering and were produced as the Hawker Siddeley HS-121 Trident and the Hawker Siddeley HS.125.
The list does not include aircraft designed by de Havilland Canada or de Havilland Australia, founded as de Havilland subsidiaries.
A separate list includes his earlier designs prior to the company formation including his first two family funded Biplanes, his various designs at the HM Balloon Factory -, and later his various designs at The Aircraft Manufacturing Company Limited.
Designs prior to company foundation
These are designs by Geoffrey de Havilland while working for himself or for other manufacturers.| Design number | Aircraft | First flight | Remarks |
| Biplane No. 1 | December 1909 | Single-seat biplane. Built with money borrowed from his maternal grandfather, de Havilland's first aircraft took two years to complete. Unfortunately, he crashed it during its first very short flight at Seven Barrows near Litchfield, Hampshire in December 1909. | |
| Biplane No. 2 | 25 September 1910 | Single-seat pusher configuration biplane – After the crash of his first aircraft, he built a fresh biplane, making his first flight in it from a meadow near Newbury in September 1910. | |
| F.E.1 | Biplane No. 2 | 25 September 1910 | Single-seat pusher configuration biplane – became the F.E.1 In December 1910, de Havilland joined HM Balloon Factory at Farnborough, which was to become the Royal Aircraft Factory He sold his second aeroplane to his new employer for £400. It became the F.E.1, the first aircraft to bear an official Royal Aircraft Factory designation. For the next three years, de Havilland designed, or participated in the design of, a number of experimental types at the "Factory". Up to about 1913 the designation letters referred to the general layout of the aircraft, derived from a French manufacturer or designer famous for that type: S.E. = Santos Experimental B.E. = Blériot Experimental F.E. = Farman Experimental From 1913/4 onwards this was changed to a designation based on the role for which the aircraft was designed. The B.S.1 of 1913 was a one-off anomaly, combining both systems: Blériot Scout. |
| S.E.1 | Santos Experimental 1 Royal Aircraft Factory | 11 June 1911 | Experimental research aircraft - originally based on a Santos monoplane design, it emerged as a pusher biplane with large balanced fore-elevators, similar in basic layout to the Wright Flyer, but with a fully covered fuselage. Ailerons were fitted to the top wing, and twin balanced rudders were mounted behind the propeller and powered by a 60 hp E.N.V. Type F engine. |
| F.E.2 | Farman Experimental 2 Royal Aircraft Factory | 18 August 1911 | Two Seat Fighter / reconnainnance - The new aircraft resembled the final form of the F.E.1, with no front elevator, but seated a crew of two in a wood and canvas nacelle, and was powered by a 50 hp Gnome rotary engine. |
| B.E.1 | Bleriot Experimental 1 Royal Aircraft Factory | 4 December 1911 | Two Seat Biplane trainer It was a two-bay tractor biplane with parallel-chord unstaggered wings with rounded ends and used wing warping for roll control and powered by a 60 hp water-cooled Wolseley engine. |
| B.E.2 | Bleriot Experimental 2 Royal Aircraft Factory | 1 February 1912 | Two Seat Biplane trainer/bomber The B.E.2 was almost identical to the B.E.1, differing principally in being powered by a 60 hp air-cooled V-8 Renault and in having equal-span wings. |
| B.S.1 / S.E.2 | Bleriot Scout 1 Scout Experimental 2 Royal Aircraft Factory | March 1913 | Single Seat Scout. small tractor biplane, was named the B.S.1 after Louis Blériot, a pioneer of tractor configuration aircraft. It had a wooden monocoque circular section fuselage, and single-bay wings. Lateral control was by wing warping. It was powered by a two-row, 14-cylinder Gnome rotary engine rated at 100 hp. |
| DH.1 | Airco DH.1 | January 1915 | Two-seat fighter/general purpose biplane In December 1913, de Havilland was appointed an inspector of aircraft for the Aeronautical Inspection Directorate. Unhappy at leaving design work at the Royal Aircraft Factory, in May 1914 he was recruited to become the chief designer at The Aircraft Manufacturing Company Limited, in Hendon. He designed many aircraft for Airco, all designated by his initials, DH. Large numbers of de Havilland-designed aircraft were used during the First World War, flown by the Royal Flying Corps/Royal Air Force. |
| DH.2 | Airco DH.2 | 1 June 1915 | Single-seat pusher biplane fighter |
| DH.3 | Airco DH.3 | Twin-engine long-range day bomber | |
| DH.4 | Airco DH.4 | August 1916 | Two-seat biplane day bomber |
| DH.5 | Airco DH.5 | October 1916 | Single-seat biplane fighter |
| DH.6 | Airco DH.6 | 1916 | Biplane trainer |
| DH.7 | Not built | Single-seat tractor fighter project with a Rolls-Royce Falcon engine, not built due to non-availability of engine | |
| DH.8 | Not built | Pusher fighter projected to be fitted with a Coventry Ordnance Works gun, not built due to delays in gun development and non-availability of specified engine | |
| DH.9 | Airco DH.9 | July 1917 | Two-seat day bomber biplane |
| DH.10 | Airco DH.10 Amiens | 4 March 1918 | Twin-engine heavy bomber biplane developed from the DH.3 |
| DH.11 | Airco DH.11 Oxford | 1919 | Twin-engined day bomber |
| DH.12 | DH.12 | Not built | Improved DH.11 powered by Dragonfly engines and modified gunner's position – unbuilt |
| DH.13 | Not used, probably due to superstition | ||
| DH.14 | (Airco) Okapi | 1919 | Two-seat day bomber to replace DH.4 and DH.9 |
| DH.15 | Airco Gazelle | 1919 | Experimental aircraft similar to DH.9 |

| DH.17 | Not built | 16 seat biplane airliner powered by two Rolls-Royce Condor engines, featuring an enclosed cabin and semi-retractable landing gear. Not built for a lack of orders due to post-WWI slump. | |
| DH.18 | (Airco) DH.18 | 1920 | 8 seat, single-engine commercial aircraft |
