Sud-Ouest Triton
Country	France
Role	Experimental trainer aircraft
First flight	11 November 1946
Built	5+2

The Sud-Ouest SO.6000 Triton was the first French jet aircraft to be manufactured and was completed during the 1940s by SNCASO. The SO.6000 design began in 1943, as a clandestine project due to the German occupation, under engineer Lucien Servanty. Shortly after the war, the French government required five prototypes to be built.

SO.6000 Triton

The Secret Project of the Occupation

The Sud-Ouest SO.6000 Triton holds the distinction of being the first French-built jet aircraft. Remarkably, its design began in secret in 1943 during the German occupation of France. Under the leadership of Lucien Servanty, engineers worked clandestinely to ensure that France would not be left behind in the “Jet Age” once the war ended. The resulting aircraft was a side-by-side two-seat trainer, though its bulbous fuselage gave it an unconventional, somewhat rotund appearance.

Engineering and Design Peculiarities

Side-by-Side Seating: Unlike many contemporary jet trainers that opted for tandem (one-behind-the-other) seating, the Triton featured a wide cockpit for side-by-side instruction. This contributed to its wide, “barrel-like” fuselage profile.
The German Engine Paradox: Ironically, the first flight of France’s “sovereign” jet was powered by a captured German Junkers Jumo 004 engine, as the intended French engines were not yet ready.
The “Nose” Intake: The Triton used a classic early-jet nose intake. In later prototypes, this was refined into a large, gaping circular intake that fed air directly back to the centrifugal-flow Rolls-Royce Nene engine.
Mid-Wing Design: The aircraft featured a straight, mid-mounted wing. This was a conservative aerodynamic choice compared to the swept-wing designs being explored in the US and USSR at the same time, reflecting the project’s early 1943 origins.

Legacy: The Foundation of French Jet Power

Limited Production: Only five prototypes were ever built. While the Triton itself never entered mass production, it served as an invaluable testbed for French pilots and engineers to learn the nuances of high-speed jet flight.
The “Nene” Connection: The installation of the British-designed, French-built Nene engine in the Triton began a long and successful partnership between Hispano-Suiza and Rolls-Royce, which powered many early French jet fighters.
Birth of the Concorde Engineer: The Triton’s lead designer, Lucien Servanty, later became the chief French engineer for the Concorde supersonic transport, showing a direct lineage from this experimental jet to the pinnacle of civil aviation.
Survivor: The first prototype (No. 01) is preserved and on display at the Musée de l’Air et de l’Espace at Le Bourget Airport near Paris.
