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 (and integration into) 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^{[ citation needed ]} 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 - (later the Royal Aircraft Factory), and later his various designs at The Aircraft Manufacturing Company Limited (Airco).

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 – (became the F.E.1) 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 (which he had used to teach himself to fly) 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 (Canard or tail-first layout) B.E. = Blériot Experimental (Tractor or propeller-first layout) F.E. = Farman Experimental (Pusher or propeller behind the pilot layout) 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 (tractor) Scout (fighter).
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 (45 kW) E.N.V. Type F engine.
F.E.2	Farman Experimental 2 (Pusher type) Royal Aircraft Factory	18 August 1911	Two Seat (Pusher) 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 (37 kW) Gnome rotary engine.
B.E.1	Bleriot Experimental 1 (Tractor type) Royal Aircraft Factory	4 December 1911	Two Seat (Tractor) 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 (45 kW) water-cooled Wolseley engine.
B.E.2	Bleriot Experimental 2 (Tractor type) Royal Aircraft Factory	1 February 1912	Two Seat (Tractor) Biplane trainer/bomber The B.E.2 was almost identical to the B.E.1, differing principally in being powered by a 60 hp (45 kW) air-cooled V-8 Renault and in having equal-span wings.
B.S.1 / S.E.2	Bleriot Scout 1 Scout Experimental 2 (Tractor type) Royal Aircraft Factory	March 1913	Single Seat (Tractor) Scout. small tractor biplane, was named the B.S.1 (standing for Blériot Scout) 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 (75 kW).
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 (Airco), 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.111		Not built	Jet bomber based on Comet I to Specification B.35/46 proposed in May 1948. Despite not meeting the Specification, it represented the most advanced aircraft that could be produced with a certainty of success within a reasonable time scale. The Comet's wing and engines and tailplane were fitted to a thinner fuselage that could carry a single 10000 lb bomb or eighteen 1000 lb bombs and a crew of four. Pilot located under a bubble canopy offset to the left with the copilot on the right side and two radar navigators/bomb aimers behind the pilot facing to the rear.
DH.112	Venom	2 September 1949	Jet fighter
DH.113	Vampire NF.10		Night fighter variant
DH.114	Heron	10 May 1950	Small airliner development of Dove
DH.115	Vampire, T.11 and export variants		two seat trainer variant
DH.116		Not built	Naval jet fighter to Specification N.114 powered by a Rolls-Royce RA.14 Avon jet engine with an estimated maximum speed of Mach 1.0 in level flight. Cockpit and fuselage were based on the Sea Venom with a new thin-section swept-back wing. Dropped in favor of the DH.110.
DH.117		Not built	Submission to F.155T, designed with straight wing and to be powered by two de Havilland Gyron Junior turbojets and one de Havilland Spectre rocket.
DH.118		Not built	Long-haul jet transport powered by four Rolls-Royce Conway jet engines. Designed as a Comet successor to carry 120 passengers on transatlantic and similar long-distance routes. Larger than the Comet but smaller than the Boeing 707, the DH.118 promised improved speed and increased range. Announced in the House of Commons on 24 October 1956, the aircraft was planned to commence operations in February 1962, but was abandoned in February 1957 in favor of the Vickers VC10. [1]
DH.119		Not built	High-speed short to medium range high-capacity airliner. Projected in 1956–1957, the DH.119 was based on Comet experience and intended to fulfill a BEA requirement. The aircraft sat 95 passengers over lengths of 1250 mi. Wings and tail surfaces were swept back 35° with four Rolls-Royce Avon jet engines mounted in pairs under the wing trailing edge. [1]
DH.120		Not built	Jet airliner similar to the DH.119, but to meet both BEA and BOAC requirements. [1]
DH.121	Hawker Siddeley Trident	9 January 1962	Three-engine jet airliner
DH.122		Not built	Proposed Trident variant to compete with the Vickers VC10. [1] Number also used for an executive aircraft project at Christchurch powered by two Gnome engines to complement the DH.123.
DH.123		Not built	Feederliner intended as a Dakota replacement. Powered by two de Havilland Gnome turboprops with a high-wing layout and a maximum capacity of 40 passengers or a payload of 7800 lb. Designed for economic operations over very short routes (e.g. 200 mi), but with a full fuel load and payload reduced to 2400 lb, the range could be extended to 1610 mi. Abandoned due to competition with the HS.748 when de Havilland joined Hawker Siddeley. de Havilland turned to the DH.126 instead. [1]
DH.124			A series of design studies for a twin-engine jet airliner with BS.75 engines on the rear fuselage and a high-swept tail. The aircraft would seat 48 passengers with room forward for cargo. Similar in size to the Hunting H.107 project.
DH.125	British Aerospace 125 initially "Jet Dragon"	13 August 1962	Medium corporate jet
DH.126		Not built	Twin jet-engine feederliner similar to the DH.125 but seating 26-32 passengers. Design put forward in May 1960, powered by two engines of 3500-4200 lb thrust range. Engines considered were the Rolls-Royce RB.173, de Havilland BS.92 and GE CF-700.
DH.127		Not built	Proposed delta-winged strike fighter for Royal Navy as Blackburn Buccaneer replacement, early 1960s. Design featured two Rolls-Royce Spey engines with vectored thrust and two Rolls-Royce RB.108 lift jets in the nose to lower approach speed. Designation chosen to avoid confusion with the Hawker P.1127 that was later designated DH.128.
