The Renard R.31 was a Belgian single-engined parasol monoplane reconnaissance aircraft of the 1930s. 32 R.31s were built for the Belgian Air Force, the survivors of which, although obsolete, remained in service when Nazi Germany invaded Belgium in 1940. The Renard R.31 was the only World War II operational military aircraft entirely designed and built in Belgium.
The R.31 was hopelessly obsolete, and those that were not destroyed on the ground in the early hours of the German Blitzkrieg invasion of Belgium in May 1940 were ravaged by German fighters as they bravely attempted to gather information on the German invasion.
