DH104 Dove
& Devon

The first new commercial aircraft to fly in the UK after the end of the Second World War.

The DH104 Dove was a short-haul small airliner developed in the 1940's as a result of the Brabazon report which mapped the future of the UK aircraft industry, post World War II.

 

Designed by Ronald Bishop, famous designer of the Mosquito and later the Comet Airliner, the Dove prototype (G-AGPJ) was flown for the first time on 25th September 1945, the twenty-fifth anniversary of the formation of the company.

 

Unlike its predecessor the DH89 Dragon Rapide, the Dove was an entirely metal construction and featured a number of key innovations such as constant feed propellers and a fully retractable tricycle undercarriage.

 

In its standard configuration, the Dove could carry between 8 and 11 passengers with an easy conversion between the two by adding or removing the lavatory compartment or the rear baggage area.  Additional to its obvious commercial airline use, the Dove often encountered more diverse roles such as aerial surveys, air ambulance and even as a Flying Classroom in more out-lying communities.  A number of aircraft were fitted out to accommodate the busy Executive role with 5 seats and a number proved popular at home and in the US market-place.

 

Typically crewed by a Pilot and Wireless Operator, a co-pilot's second set of controls could quickly and easily be fitted for the more long endurance flights.

 

544 Dove were built in a production run that extended for twenty-three years, the last aircraft built being G-AVVK, a Dove Mk 8 delivered in February 1968.

 

The aircraft was of a very elegant appearance, with clean lines and a sweeping dorsal fin reminiscent of that fitted to the DH103 Hornet fighter. The initial production model, the Dove 1, was powered by two 330hp Gipsy Queen 70 engines.

Various models of the Gipsy Queen engine were used throughout the production run, power being increased progressively to 400hp by the time the final models, the Dove 7 and 8 appeared. The increased power allowed an increase in all up weight for improved payload range performance.

 

Later military transport and communication aircraft were know as the Devon C Mk1 & Mk2 with a Sea Devon serving with the Royal Navy.

 

By far the largest order for the type was placed by Argentina who eventually took 70 aircraft, most used by the Argentinian Air Force.  Over 50 aircraft were sold in the USA whilst the initial batch of 30 aircraft for the RAF were used for over 30 years in a VIP and transport mode.  The Royal New Zealand Air Force also took 30 aircraft which lasted in service until the mid-1970's.

The Dove 7 and 8 also featured a smooth upper canopy line, similar to that adopted for the DH114 Heron. 39 Dove 4 aircraft were delivered to the RAF for communication duties as the Devon C.Mk.1; 13 similar aircraft were supplied to the Royal Navy as the Sea Devon C.Mk.20.

 

A number of aircraft were re-engined with two 400hp Lycoming IO-720 engines; these aircraft featured a large, exaggeratedly swept, fin and were known as the Riley 400. A few aircraft received the Lycoming engines but retained the original tail surfaces.

Whilst a number of aircraft are still considered to be 'live' aircraft, none have a certificate to fly at present.
