The Supermarine S.6 was a British single-seat racing seaplane that first flew in 1929, exemplifying interwar high-speed achievement. With a 9.1-metre wingspan and single engine, it reached 575.7 km/h. Its 7.9-metre fuselage embodied the cutting edge of hydrodynamic and aeronautical engineering during the Golden Age of air racing.
