The Renault FT-17 was a French tank which was extensively used in World War I as it was manufactured in 1917. It was the first tank made with a fully rotating turret on top, engine in the back and the driver in front; a configuration that has been repeated in the majority of tanks until today.
The Renault FT-17 was a light tank designed by Rodolphe Ernst-Metzmaier in 1917 and was manufactured by Renault the same year. It weighed 6.5 tonnes, measured 5 m in length, 1,47 m in width, and 2.14 m in height, and had a capacity for a crew of two. The Renault FT-17 was powered by a Renault 4-cylinder, petrol engine of 39 hp. The tank was armed with a 37 mm gun, or a 7.92 mm machine gun. It had an operational range of 60 km and a speed of 7 km/h. Its armor was 22 mm wide.
The Renault FT-17 saw action for the first time by the end of 1917. Then the tank was widely used by the French and the Americans after May 31, 1918, during the Hundred-day Offensive. Because the FT-17 was unexpensive, it was well-suited for mass production. 84 were produced in 1917, but 2,697 were delivered before the end of the war. Around 3,177 FT-17 tanks were produced in total. After World War I this light tank was used in many other conflicts, such as the Russian Civil War, Polish-Soviet War, Chinese Civil War and Spanish Civil War.
