Development of the S.13 was started in 1947. This versatile aircraft could be used to train advanced pilots, navigators, bomb aimers, radio-telegraphers and observers. It was also suitable for the training of paratroopers and for aerial mapping. Test pilot Burgerhout made the first flight of the S.13 at Schiphol on March 13th, 1950. An intended order from KLM did not materialise owing to a gift of Beechcraft aeroplanes from America. The sole prototype was used during the flood disaster of February 1953 to photograph the inundated areas.
