Société Nationale de Construction Aéronautique (SNCA) du Sud-Est was formed in 1936 by the nationalisation of Loiré-et-Olivier, Romano and Société Provençale de Constructions Aéronautiques; SNCA du Midi, previously Dewoitine, was added in 1941. Having enjoyed modest success with its Languedoc and Armagnac airliners, Sud-Est responded eagerly to a 1951 French Government specification for a medium-range airliner capable of carrying up to 65 passengers and 1,000 kg of cargo at speeds of up to 600 km/h on routes from France to North Africa. Initially conceived with three engines, the availability of more powerful Avon turbojets led to the adoption of the then-novel layout of one engine mounted on each side of the rear fuselage. Sud-Est saved on developmental costs through use of the nose and cockpit sections from the De Havilland Comet.
A contract for two prototypes was awarded to Sud-Est by the French Government on 2 July 1953, with the first production order following on 3 February 1956, an Air France commitment for 12 aircraft. Other orders were received from Scandinavian Airlines System (for six aircraft) and United Air Lines (for 20), and production was launched in mid-1957. A highly anticipated order from Trans World Airlines led to a change in the transatlantic partner from Republic to Douglas, but an order was not forthcoming, TWA selecting the Boeing 727 instead. Despite this setback, Caravelle production continued steadily for a further 10 years. The last active Caravelle, operational in the Democratic Republic of Congo, was retired in July 2005.
