List of de Havilland aircraft

none

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 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 kept 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.

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 Biplane No. 2 25 September 1910 Single seat pusher configuration biplane – became the F. E.1 when de Havilland joined the staff at the Royal Aircraft Factory DH.1 Airco DH.1 January 1915 Two seat fighter/general purpose biplane DH.2Airco DH.2 1 June 1915 Single seat pusher biplane fighter DH.3Airco 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

Design study for a Napier Sabre powered twin engine fast bomber derivative, developed into DH.101 concept. Number later allocated to a light single engine civil biplane intended as DH.87 replacement. This was abandoned due to WWII. DH.100 Vampire, (known as Spider Crab until April 1944). 29 September 1943 Twin boom jet fighter DH.101 Not built High speed, high altitude unarmed night intruder with Napier Sabre engines to Specification B.11/41 and based on the Mosquito. Despite priority over the Vampire jet fighter, a shortage of Sabre engines resulted in the DH.101's abandonment in April 1942 in favor of the lower powered DH.102. DH.102 Not built Night bomber to Specification B.4/42, with two Rolls Royce Merlin or Griffon engines. Designed to carry a 5000 lb bomb load at lower speed than the Mosquito. Officially approved in April 1942 as the Mosquito Series II, but work was stopped in late 1942. DH.103 Hornet and Sea Hornet 28 July 1944 Twin engine fighter DH.104 Dove and Devon 25 September 1945 8 passenger airliner, military transport and communications DH.105 Not built Three seat primary trainer with fixed landing gear to Specification T.23/43. Production contract won by the Percival Prentice. DH.106 Comet 27 July 1949 Jet airliner DH.107 Not built Proposed development of the Vampire that eventually became the Venom. DH.108 de Havilland DH 108 "Swallow" 15 May 1946 Swept wing experimental aircraft DH.109 Not built Design study for a four engine airliner. Designation also possibly used for a naval strike aircraft to Specification N.8/49. DH.110 Sea Vixen 26 September 1951 Two seat naval fighter 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. 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. DH.120 Not built Jet airliner similar to the DH.119, but to meet both BEA and BOAC requirements. 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. Number also used for a executive aircraft project at Christchurch powered by two Gnome engines to compliment 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. 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.
