The Somua S40 was a prototype French tank developed before the Second World War. It was based on the Somua S35. Compared with the latter, the S40 had a new 220hp diesel engine; its hull was longer than the S35; and an extra pair of wheels was added on the suspension. The S40 also had a new turret, the ARL 2C.
Mass production was planned for the S40. However, production was cancelled after the Fall of France in 1940.[1] [2]
