The F27 was developed during the early 1950s with the expressed intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the successful Douglas DC-3. A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation. Innovative manufacturing techniques were also employed in the aircraft's construction. It has the distinction of being the most numerous post-war aircraft to have been manufactured in the Netherlands; the F27 was also one of the most successful European airliners of its era. The Friendship was one of the most widely used airliners in Australia, used by most mainstream airlines, (Ansett, TAA, East West, MMA, Virgin, et al), as well as the CSIRO and Dept.of Civil Aviation.
