The de Havilland DH.104 Dove is a British short-haul airliner developed and manufactured by de Havilland. It is a monoplane successor to the prewar de Havilland Dragon Rapide biplane. The design came about from the Brabazon Committee report which, amongst other aircraft types, called for a British-designed short-haul feeder for airlines.
The Dove was a popular aircraft and is considered to be one of Britain's most successful postwar civil designs, in excess of 500 aircraft were manufactured between 1946 and 1967. Several military variants were operated, such as the Devon by the Royal Air Force, the Sea Devon by the Royal Navy, the type also saw service with a number of overseas military forces.
A longer four-engined development of the Dove, intended for use in the less developed areas of the world, was the de Havilland Heron.
The development team for the Dove was headed by Ronald Eric Bishop, the creator of the de Havilland Mosquito, a wartime fighter-bomber, and the de Havilland Comet, the first commercial jet aircraft in the world. It had been conceived as a replacement to the pre-war de Havilland Dragon Rapide, and also needed to be competitive with the large numbers of surplus military transports in the aftermath of the Second World War. The Dove could also serve as a dedicated executive transport, which proved to be popular with overseas customers, particularly in the United States.
Production of the Dove and its variants totalled 542 including 127 military Devons and 13 Sea Devons. The first deliveries to customers were made in Summer 1946, the final example of the type was delivered in 1967. Initial production of the Dove was at de Havilland's Hatfield factory, but from the early 1950s the majority of aircraft were built at the company's Broughton facility near Chester.
The Dove first flew on 25 September 1945. From summer 1946 large numbers were sold to scheduled and charter airlines around the world, replacing and supplementing the prewar designed de Havilland Dragon Rapide and other older designs.
The largest order for the Dove was placed by Argentina, which ultimately took delivery of 70 aircraft, the majority of which were used by the Argentine Air Force.[page needed] LAN Chile took delivery of twelve examples and these were operated from 1949 onwards until the aircraft were sold to several small regional airlines in the United States in 1954.[page needed]
In excess of 50 Doves were sold to various operators in the United States by Jack Riley, an overseas distributor for the type. De Havilland later assumed direct control of U.S. sales, however did not manage to match this early commercial success for the type.
An initial batch of 30 Devons was delivered to the Royal Air Force, these aircraft were used as VIP and light transports for over 30 years. The Royal New Zealand Air Force acquired 30 Devons between 1948 and 1954 and these remained in service for VIP, crew-training and light transport duties into the 1970s.[page needed]
The Biafran Air Force operated a single Dove during the Nigerian Civil War, the aircraft was lost and subsequently found in 1970 on the premises of a school in Uli. A second US-registered Riley Dove N477PM delivered in 1967 to Port Harcourt from Switzerland never reached Biafra because it was stopped by Algerian authorities.
A few Doves and civilianised Devons remain in use in 2011 in the United Kingdom, Canada, Germany and elsewhere with small commercial firms and with private pilot owners.
