The Sud-Est LeO H-246 was a large four-engined flying boat from the late 1930s.
The LeO H-246 was designed by the French aircraft manufacturer Lioré-et-Olivier to meet a 1935 specification for a commercial flying boat for use on the Mediterranean routes of Air France. It was a four-engined parasol monoplane of mixed construction and powered by four 720 hp (537 kW) Hispano-Suiza 12Xir liquid cooled V12 engines. All four engines were mounted in streamlined nacelles ahead of the leading edge of the wing. It had a duralumin hull of similar layout to that of Lioré et Olivier's H-47 which accommodated seats for 26 passengers and a crew of four.
The prototype H-246.01 (Lioré et Olivier's factories had been nationalised at the end of 1936, so the aircraft was built by Sud-Est) made its maiden flight from the Étang de Berre on 30 September 1937.Air France placed an order for six H-246.1 aircraft in January 1938, with the prototype also being brought up to production standard for commercial service.
The refurbished prototype and the first production aircraft were being readied for commercial service when the Second World War broke out in September 1939. The French Navy drew up plans to requisition the H-246s as maritime patrol aircraft, but Air France still needed them, and the Navy agreed to take over only four of the aircraft. This allowed Air France to commence operations with the prototype on the Marseille–Algiers route on 14 October 1939.
The third production aircraft was completed for the Navy in June 1940, with a glazed position in the nose for a bombardier/navigator, bomb racks below the wings and four 7.5 mm Darne machine guns as defensive armament. It entered service with Escadrille 9E on 25 August 1940, the only aircraft of the type actually to be operated by the French Navy, with the remaining aircraft going to Air France.
