History

The SV.4 was designed as a biplane tourer/training aircraft in the early 1930s, by Stampe et Vertongen in Antwerp. The first model was the SV.4A, an advanced aerobatic trainer, followed by the SV.4B with redesigned wings and the 130 hp/97 kW de Havilland Gipsy Major engine.
Only 35 aircraft were built before the company was closed during the Second World War. After the war, between 1948 and 1955, the successor company Stampe et Renard built a further 65 aircraft as trainers for the Belgian Air Force.
A licensed SV.4C version was built in France by SNCAN (Société Nationale de Constructions Aéronautiques du Nord), and in Algeria by Atelier Industriel de l'Aéronautique d'Alger, the two firms completing a combined total of 940 aircraft. The postwar SV.4Cs were widely used by French military units as a primary trainer. Many also served in aeroclubs in France, numbers of which were later sold second hand to the United Kingdom and other countries. The Rothmans Aerobatic Team flew SV.4C aircraft from 1970 to 1973.[1]
