The SNCASE SE.161 Languedoc was a French four-engined airliner produced by SNCASE (Sud-Est). Developed from the Bloch MB.160 and known in the late 1930s as the (SNCSO) Bloch MB.161, the SE.161 was in service with Air France and the French military after World War II. In 1936, Air Afrique needed a new airliner for its African services. Marcel Bloch proposed a development of his Bloch MB.160 aircraft, the Bloch MB.161, which after World War II became the SNCASE SE.161 Languedoc. Design work on the new aircraft began in 1937. The prototype, F-ARTV, first flew on 15 December 1939. It was powered by four Gnome-Rhône 14N radial engines of 1,020 hp (760 kW) each. The aircraft underwent a slow development programme and the test flying was not completed until January 1942. The French Vichy government placed an order for twenty in December 1941, but none were built. The programme was finally abandoned following Allied bombing of the factory at Saint-Martin-du-Touch [fr], Haute-Garonne in 1944. After the liberation of France the provisional government led by General De Gaulle authorised production to be resumed with the first series production aircraft, designated the SE.161 and registered F-BATA, first flying either on 25 August 1945 or 17 September 1945. An initial batch of 40 production examples was completed for Air France between October 1945 and April 1948. The Languedoc was an all-metal four-engined low wing cantilever monoplane airliner with twin fins and rudders. It had a crew of five (pilot, co-pilot/navigator, radio operator, flight engineer and steward) Standard cabin accommodation was for 33 passengers seated in eleven rows of three, two on the starboard side and one to port. An alternative first class arrangement was for 24 seats. A 44-seat higher density version was introduced by Air France in 1951. The Languedoc was fitted with underwing retractable main undercarriage wheels and a tailwheel landing gear and was powered by four 1,020 hp (760 kW) Gnome-Rhône 14N 44/45 or 54/55 radial engines in wing-leading edge nacelles, with partial convertibility to inline water-cooled pistons. A total of 100 aircraft were built for Air France, the French Air Force and French Navy. Several examples were utilised as test aircraft with the CEV at Villacoublay and elsewhere. The only export customer for new production aircraft was the Polish airline LOT which bought five with some being refitted with Pratt & Whitney R-1830 Twin Wasp radial engines.
